Original type series Lectotype ♀ (ANSP). Cresson (1877, p. 200) described Platylabus canadensis from ‘Hab.– Canada’ without specifying the number of specimens included in the description. Cresson (1916, p. 23) in his list of types, simply reported the type to be a female and in ‘ I n good condition’, without clarifying the number of specimens. Townes (1944, p. 311) and Townes and Townes (1951, p. 280) did not specify any number of specimens either. Later on, Heinrich (1962b, p. 776) referred to the specimen as the ‘Holotypus’. Carlson (1979, p. 317) expressed the assumption that Cresson (1916) ‘indicated which single specimen was to be regarded as the type for each; thus he selected lectotypes for those cases in which he had described a species from more than one specimen’. Hopper (1984, p. 968) reported being unable to see how it can be claimed that Cresson (1916) indicated a single specimen to be the type. This statement contradicted Cresson’s (1916, p. 1) own statement that ‘In selecting the single type the author has been governed by the present condition of the original material, and has always selected the perfect, or more nearly perfect specimen’ and suggests that Hopper (1984) overlooked this clear indication of Cresson’s (1916) intention to select a single name-bearing type (i.e. a lectotype in the modern sense). Cresson’s (1916) lectotype designation was valid and no subsequent lectotype designation has any validity (ICZN 1999, Article 74.1.1). The fact that the selected specimen eventually could no longer be traced, as suggested by various subsequent authors (Heinrich 1962b, p. 780; Hopper 1984), could be explained by collection mismanagement and has no influence on the validity of the lectotype selection. Only a careful study of Cresson’s collection can provide more insights. Heinrich’s (1962b, p. 776) employment of the term ‘holotypus’ is in error., Published as part of Dal Pos, Davide, Heilman, Victoria & Welter-Schultes, Francisco, 2022, Platylabini (Hymenoptera: Ichneumonidae: Ichneumoninae) of the south-eastern United States: new distributional data, taxonomic notes, illustrated keys, and an annotated catalogue of the genera and species, pp. 1869-1938 in Journal of Natural History 56 on pages 1884-1885, DOI: 10.1080/00222933.2022.2134061, http://zenodo.org/record/7397619, {"references":["Cresson ET. 1877.

Probolus Wesmael, 1845 Ichneumon (Probolus) Wesmael, 1845: 150. Type species originally Ichneumon fossorius Linnaeus, 1758, by monotypy. This type species was set aside because it was misidentified, and a new type species Ichneumnon culpatorius Linnaeus, 1758 was fixed under ICZN Article 70.3.2, by Horstmann (2000). Notes Type species originally fixed as Ichneumon fossorius Linnaeus, 1758, by monotypy, with a second species Ichneumon alticola Gravenhorst, 1820 included with doubts (not belonging to the originally included nominal species under ICZN 1999, Article 67.2.5). Wesmael (1845) did not cite an authorship for I. fossorius. Subsequent authors attributed the name incorrectly to Gravenhorst (1820) and recognised this as a different species (Ashmead 1900a, p. 19; Viereck 1914, p. 122; Townes et al. 1965, p. 509). Gravenhorst (1820, p. 285) used the Linnean name subsequently and did not establish a new name. Under ‘No. 9 Ichneumon subsericans ’, Gravenhorst reported I. fosssorius as used by Linnaeus and other authors, to belong to the species I. subsericans Gravenhorst, 1820. Under ‘No. 10 Ichneumon fossorius ’, Gravenhorst (1820, p. 285) presented a species under the name I. fossorius and explained that he used this name in the sense of Fabricius (and Walckenaer and Müller), not of Linnaeus. Gravenhorst (1820) did not intend to establish a new name, but used subsequently the previously established name I. fossorius Linnaeus, 1758, in the taxonomic sense of Fabricius and other authorities. So, this usage was a misidentification of I. fossorius Linnaeus, 1758 sensu Fabricius, Walckenaer and Müller (Gravenhorst did not provide bibliographic references). Such a misidentified name cannot be taken to establish a new available name (ICZN 1999, Article 49). Thus, no new name was established, either by Fabricius or by Gravenhorst (1820). Carlson (1979, p. 513) interpreted ‘ Ichneumon fossorius Gravenhorst, 1820 ’ as a deliberate misidentification of Ichneumon fossorius Linnaeus, 1758 by Gravenhorst (1829, p. 164). Such a case would fall under ICZN Articles 11.10 and 67.13, but only if the deliberately misidentified species was employed to establish a new genus or subgenus. This situation does not apply here. Wesmael (1845) did not demonstrate awareness of a misidentification when establishing Probolus. Horstmann (2000) reported that Wesmael (1845) misidentified the type species (confirming previous statements by Wesmael (1848) and Wesmael (1853)), and that three female specimens in the collection matched the description of the Probolus type species by Wesmael (1845). These specimens belonged to Ichneumon culpatorius Linnaeus, 1758 in the taxonomic judgement of Horstmann (2000). Horstmann (2000) cited Article 70.3, stating that I. culpatorius Linnaeus, 1758 shall be the type, originally misidentified as I. fossorius in the type fixation by monotypy by Wesmael (1845). Horstmann (2000) attributed I. fossorius to ‘ Gravenhorst 1820 ’; however, incorrect authorship and date citations are immaterial in such acts, and in any case the authorship does not form part of the name (ICZN 1999, Articles 67.7 and 51.1). By this action Horstmann (2000) validly fixed I. culpatorius as the type species of Probolus., Published as part of Dal Pos, Davide, Heilman, Victoria & Welter-Schultes, Francisco, 2022, Platylabini (Hymenoptera: Ichneumonidae: Ichneumoninae) of the south-eastern United States: new distributional data, taxonomic notes, illustrated keys, and an annotated catalogue of the genera and species, pp. 1869-1938 in Journal of Natural History 56 on pages 1920-1921, DOI: 10.1080/00222933.2022.2134061, http://zenodo.org/record/7397619, {"references":["Wesmael C. 1845.

Regarded as synonym of I. clarus by Bradley (1903: 280). Original type series Holotype ♀ of Platylabus clarus, by monotypy (ANSP); holotype ♀ of Platylabus magnificus, by monotypy (LUEC). Cresson (1867, p. 297) described Platylabus clarus based on ‘One ♀ specimen’. Therefore, this specimen is here referred to as the holotype fixed by monotypy (ICZN 1999, Article 73.1.2). Provancher (1886, p. 36) described Platylabus magnificus based on ‘Une seule ♀ capturée Bécàncour’ (= only one ♀ captured at Bécàncour). Gahan and Rohwer (1918a, p. 168) designated a lectoype, but as Barron (1975, p. 503) acknowledged, there is no need for a lectotype as Provancher clearly mentioned only one specimen. Therefore, this specimen is here referred to as the holotype fixed by monotypy (ICZN 1999, Article 73.1.2) and Gahan and Rohwer’s (1918a, p. 168) designation should be considered an invalid lectotype designation. Type locality United States of America, Massachusetts, Ridings (Platylabus clarus). Canada, Québec, ‘Bécancour’ (Platylabus magnificus). Heinrich (1962b, 1977) reported New Hampshire as the type locality for Platylabus clarus, even though the type locality, as reported by Cresson (1867, p. 297), is Massachusetts, while New Hampshire is a locality later added by Cresson (1877, p. 199).

Host Caripeta divisata Walker (Bradley 1978), Eutrapela clemataria J.E. Smith (Bradley 1978; Bugg et al. 1989), Phaeuora quernaria J.E. Smith (Bradley 1978) (Lepidoptera: Geometridae). Bradley (1978, p. 6) reported also one ‘ Noctuidae ’ among the possible hosts for the species, without mentioning any genus or species. Further investigations are needed to confirm the record. Male The first description of a male was provided by Cresson (1877, p. 199), but Heinrich (1962b, p. 705) believed that he himself was describing the male for the first time (referring to it as neallotype). Comments This species is widespread across the entire eastern part of North America, as stated by Townes and Townes (1951) and Carlson (1979), where it is the Platylabus with the southernmost distribution (reaching Florida) (Heinrich 1977; Yu et al. 2016). Heinrich (1962b) stated that he has never seen specimens of this species from the west, but the species was reported by Guppy (1948, p. 13) for Vancouver Island (British Columbia). However, this last record is inconsistent as the author listed the species for the island but also added a comment by Henry Townes – the one responsible for the determination – who stated that the species was ‘not recorded from the West’. It is unclear whether he was referring to the western United States or more generally to western North America. Subsequent records by Foxlee (1954, p. 13) and Bradley (1978, p. 6) provided new evidence of the species occurring in the West, specifically at Robson, British Columbia. There are several images of the species on BugGuide. However, we preferred to be cautious with including those records within this publication as there are species morphologically very similar to Platylabus clarus (e.g. Platylabus divisatae Heinrich, 1963 or Platylabus hyperetis Heinrich, 1962), which could prevent a correct identification from photos. Townes (1944) proposed that Platylabus metallicus Bradley, 1903 was a junior synonym of P. clarus without providing any comments, while Heinrich (1959, p. 215) rejected this view, noting that Townes (1944) misidentified some specimens as Platylabus clarus when they actually belonged to the former species., Published as part of Dal Pos, Davide, Heilman, Victoria & Welter-Schultes, Francisco, 2022, Platylabini (Hymenoptera: Ichneumonidae: Ichneumoninae) of the south-eastern United States: new distributional data, taxonomic notes, illustrated keys, and an annotated catalogue of the genera and species, pp. 1869-1938 in Journal of Natural History 56 on pages 1905-1907, DOI: 10.1080/00222933.2022.2134061, http://zenodo.org/record/7397619, {"references":["Cresson ET. 1867.

Asthenolabus Heinrich, 1951 Stenolabus Heinrich, 1935: 197. Type species: Platylabus lastiscapus Thomson, 1894, by original designation. Preoccupied by Stenolabus Schulthess-Rechberg, 1910 (Hymenoptera: Vespidae). Asthenolabus Heinrich, 1951: 240. New replacement name for Stenolabus, 1935. Comparative diagnosis The very elongate and narrow sickle-shaped propodeal spiracles (Figure 9b) set Asthenolabus apart from Apaeleticus, Carlsonia, Cyclolabus and Lincyus (all with small and round propodeal spiracles). However, this feature places Asthenolabus close to Platylabus and Tropicolabus from which it can be distinguished by the very superficial, almost obsolete, gastrocoeli and thyridia (Figure 9d), and to Probolus from which it can be distinguished by the presence of propodeal carinae and the absence of a hump in the anterior part of the postepetiole (Heinrich 1961, 1962b; Tereshkin 2009). Range and diversity The genus is known only from the Nearctic, Palearctic and Indomalayan regions, with three species in North America, of which only one, Asthenolabus canadensis (Cresson, 1877), occurs in the south-eastern United States (Heinrich 1962b; Yu et al. 2016)., Published as part of Dal Pos, Davide, Heilman, Victoria & Welter-Schultes, Francisco, 2022, Platylabini (Hymenoptera: Ichneumonidae: Ichneumoninae) of the south-eastern United States: new distributional data, taxonomic notes, illustrated keys, and an annotated catalogue of the genera and species, pp. 1869-1938 in Journal of Natural History 56 on pages 1882-1884, DOI: 10.1080/00222933.2022.2134061, http://zenodo.org/record/7397619, {"references":["Heinrich G. 1951.

Original type series Holotype ♂, by monotypy (ANSP). Davis (1898, p. 353) clearly stated that the description was based on only ‘One specimen from Camden, N.J’. This specimen can be referred to as the holotype designated by monotypy (ICZN 1999, Article 73.1.2). Type locality United States of America, New Jersey, Camden. Type specimens examined (Figures 38b, 40 d-f) Holotype: ‘[White label] Camden N.J./92 // [White label] Platylabus / foxi /Davis/ [White label] COLLECTION OF/G. C.

Stange, 1♀ (FSCA). Updated distribution (Figure 41) New Jersey (Davis 1898); Florida (new state record). Host Unknown Female Hereby described for the first time (see below). Comments Davis (1898, p. 352) described Platylabus foxi based on a single male specimen from Camden (New Jersey). The taxon was later synonymised under Thaumatoteles ornatus (= Ambloplisus ornatus) by Townes (1944, p. 314) without adding any evidence or comments for the new synonym. Heinrich (1959, p. 216), after examining the holotype, resurrected foxi, noting that it can be easily distinguished from Ambloplisus ornatus by the characters mentioned above (see Comparative diagnosis). The specimen hereby examined and described represents the first record since the original description as well as the first record for the south-eastern United States, and the first female of the species. The current scattered distribution (Figure 40f) indicates that the species has been overlooked in collections for many years, due to the considerable chromatic convergence with Ambloplisus ornatus.

Linycus Cameron, 1903 Linycus Cameron, 1903: 234. Type species: Linycus rufipes Cameron, 1903, by monotypy. Comparative diagnosis From all the other four Nearctic Platylabini genera with small, circular or roundish propodeal spiracles – Apaeleticus, Carlsonia, Cyclolabus and Neolinycus – Linycus can be easily distinguished by the combination of different features. The subobsolete gastrocoeli, represented only by narrow and shallow, oblique, longitudinal depressions, bearing some coarse, irregular, longitudinal rugae (Figure 15d), set Linycus apart from Cyclolabus (which has strongly pronounced gastrocoeli, with thyridia larger than the space between them (Figure 13e)) and, in addition to these features, the presence of distinct propodeal carinae (Figure 15d) allows separation from Apaeleticus (which has a strongly reticulated and completely areolated propodeum (Figure 7a)). Lastly, Linycus differs from Carlsonia by the structure of the head, which is not as broad and strongly convex, but narrower and less bulging, and from Neolinycus Heinrich, by the structure of the temples, which are not strongly reduced, but moderately developed (Figure 15b) (Heinrich 1961, 1962b, 1977; Tereshkin 2009). Range and diversity The genus Linycus has a Holarctic and Oriental distribution, with four species in the Nearctic, only one occurring in the south-eastern United States (Heinrich 1962b, 1971, 1975; Yu et al. 2016)., Published as part of Dal Pos, Davide, Heilman, Victoria & Welter-Schultes, Francisco, 2022, Platylabini (Hymenoptera: Ichneumonidae: Ichneumoninae) of the south-eastern United States: new distributional data, taxonomic notes, illustrated keys, and an annotated catalogue of the genera and species, pp. 1869-1938 in Journal of Natural History 56 on pages 1892-1893, DOI: 10.1080/00222933.2022.2134061, http://zenodo.org/record/7397619, {"references":["Cameron P. 1903.

Current distribution (Figure 24) UNITED STATES OF AMERICA: Louisiana (Heinrich 1977). Host Unknown. Male Unknown. Comments This species is known only from the type locality and a single female specimen. Heinrich (1977, p. 275), while describing this species, acknowledged that it could represent a subspecies of P. clarus Cresson, 1867, adding the fact that if this is the case, then the male of P. clarus recorded for Louisiana should be attributed to the new taxon. However, he tentatively ranked P. flavidoclarus as a species. We have examined a male specimen, collected in Georgia, and housed at the FSCA, that could be a male of this species, due to the very extensive white markings on the entire body. However, more material is needed to corroborate our hypothesis and, therefore, we do not describe it here., Published as part of Dal Pos, Davide, Heilman, Victoria & Welter-Schultes, Francisco, 2022, Platylabini (Hymenoptera: Ichneumonidae: Ichneumoninae) of the south-eastern United States: new distributional data, taxonomic notes, illustrated keys, and an annotated catalogue of the genera and species, pp. 1869-1938 in Journal of Natural History 56 on pages 1907-1908, DOI: 10.1080/00222933.2022.2134061, http://zenodo.org/record/7397619, {"references":["Heinrich G. 1977.

Original type series Lectotype ♀, designated by Gahan and Rohwer (1918b, p. 136) (CNCI). Provancher (1886, p. 56) described Phygadeuon gracilicornis from ‘Ottawa (Harrington) [= collected by Harrington]’ without specifying the number of female specimens included in the description. Gahan and Rohwer (1918b, p. 136) designated a lectotype, addressing it as ‘Type– Female, Harrington Coll. Left antenna broken’. Subsequently, Heinrich (1962b, p. 763) incorrectly employed the term ‘Holotypus’ for a female specimen from ‘ Ontario (Ottawa). C.N.C’. Barron (1975, p. 478) designated a lectotype, arguing that both Gahan and Rohwer’s (1918b) and Heinrich’s (1962b) actions did not constitute valid lectotype designations since the authors ‘did not specify a particular specimen’. Barron’s (1975) observations appear to be wrong. Not being able to recognise the specimen in the collection does not invalidate the designation (ICZN 1999, Article 74.1.1). Gahan and Rohwer’s (1918b, p. 136) designation is valid and Barron’s (1975) invalid. Heinrich (1962b, p. 763), on the other hand, was relatively more specific in referring to a female specimen housed at the CNCI. However, his employment of the term ‘holotypus’ was in error. Therefore, the valid lectotype designation is the one established by Gahan and Rohwer (1918b, p. 136), while Barron’s (1975, p. 478) designation should be considered invalid. Type locality Canada, Ottawa. No type locality is given on the lectotype labels, but the species has been described from Ottawa in the Harrington collection, now housed at CNCI.

Host Cladara limitaria nigroangulata Strecker, Eupithecia ornata Hulst (Lepidoptera: Geometridae) (Bradley 1978). Male The first description of a male was provided by Heinrich (1962b, p. 763), who referred to the specimen as the neallotype. Comments Davis (1895, p. 285) provides a new combination of this species under the generic name ‘ Herpistomus ’. We are not aware of Provancher having used the name Herpistomus for a genus in ichneumonids, and all other circumstances suggest that Berthoumieu must have had Herpestomus in mind. Therefore, and in agreement with Townes (1944, p. 315), we regard Herpistomus as an incorrect subsequent spelling of Herpestomus Wesmael, 1845 (ICZN 1999, Article 33.3). Following Heinrich (1959, p. 216), Probolus subdentatus Ashmead, 1902 is treated as a subspecies of Cyclolabus gracilicornis. This subspecies has a northern distribution but has been recorded by Heinrich (1962b) for North Carolina without any other information on the specificity of the record. Carlson (1979) reported the species for Michigan, but Yu et al. (2016) did not record it for the state. There is another subspecies, Cyclolabus gracilicornis subdentatus (Ashmead, 1902), within North America, but it does not occur in the south-east of the United States (Heinrich 1962b, p. 763)., Published as part of Dal Pos, Davide, Heilman, Victoria & Welter-Schultes, Francisco, 2022, Platylabini (Hymenoptera: Ichneumonidae: Ichneumoninae) of the south-eastern United States: new distributional data, taxonomic notes, illustrated keys, and an annotated catalogue of the genera and species, pp. 1869-1938 in Journal of Natural History 56 on pages 1888-1892, DOI: 10.1080/00222933.2022.2134061, http://zenodo.org/record/7397619, {"references":["Provancher L. 1886.

Apaeleticus Wesmael, 1845 Apaeleticus Wesmael, 1845: 166. Type species: Apaeleticus bellicosus Wesmael, 1885, by subsequent designation of Ashmead (1900a: 22). Comparative diagnosis From all the other Nearctic Platylabini genera, Apaeleticus can be easily distinguished by this combination of characters: (1) strongly developed sternauli; (2) middle field of face strongly protruding (Figure 7c); (3) roughly irregularly cellular-wrinkled sculpture of propodeum with small, sharp teeth (Figure 7a); and (4) truncated apex of metasoma, with hidden sixth and seventh tergites retracted under the fifth (Figure 7c) (Heinrich 1961, 1962b; Tereshkin 2009). Range and diversity Only two species in the Nearctic, of which only one occurs in the south-eastern United States, Apaeleticus americanus Cushman, 1926. Notes There is a discrepancy in reporting the year of description of the genus, with Heinrich (1962b, p. 791) reporting 1844 and Yu et al. (2016) reporting 1845. The work by Wesmael (1845) has ‘1844’ printed on the cover of the article, but it was included in the journal Nouveaux Mémoires de l’Académie Royale des Sciences, des Lettres et Beaux-Arts de Belgique, volume 18, published in 1845, as reported by the cover of the journal itself.

Key to the tribes of Ichneumoninae of North America and genera ofPlatylabini of the south-eastern United States The following key is based on the results from Santos et al. (2021) and adapted from Heinrich (1961, 1962b), Tereshkin (2009), and Valemberg (2014). Since the character ‘first metasomal tergite broader than high’ (first couplet) can be difficult to score, Apaeleticus and Probolus can be keyed out from both statements in the first couplet. 1.

Updated distribution (Figure 6) MEXICO (Berthoumieu 1904); UNITED STATES OF AMERICA: Florida (Heinrich 1977), Georgia (new state record), Iowa (Heinrich 1962b, wrongly mentioned as Idaho, see Comments), Illinois (Nason 1905), Maryland (Townes and Townes 1951), Massachusetts (Carlson 2011), New York (Cresson 1868), North Carolina (Heinrich 1962b). Host Unknown. Male The first description of a male was provided by Heinrich (1962b, p. 790), who referred to the specimen as the neallotype and stated that the specimen was tentatively placed under Ambloplisus ornatus because of the colour variation between the two sexes. The association was later confirmed by Heinrich (1977, p. 277), who collected on the ‘same small bush’ first the female and subsequently thereafter the male. Comments Townes and Townes (1951, p. 281) reported the species for Maryland (not recorded by Yu et al. 2016), New York, and New Jersey. However, the New Jersey record belongs to Tropicolabus foxi (Davis, 1898), a species that was synonymised under Ambloplisus ornatus by Townes (1944, p. 314) (as Platylabus foxi), and later resurrected by Heinrich (1959, p. 216), who placed it under the newly described genus Tropicolabus Heinrich (see below). Therefore, Ambloplisus ornatus is not known for New Jersey. The records from Massachusetts and Ohio are from BugGuide and identified by Carlson (2011) as Ambloplisus ornatus. However, these have not been recorded in any paper or catalogue (see Yu et al. 2016). Another record missing from Yu et al. (2016) is the one from Illinois by Nason (1905, p. 149) whose specimens were identified by the Ichneumonid expert G.C. Davis. Heinrich (1962b, p. 790) reported a specimen in the USNM from Idaho, but as noted by Carlson (1979, p. 547), who analysed the same specimen, the actual locality is in Iowa. Unfortunately, Yu et al. (2016) listed Idaho as a locality for the species, without mentioning Iowa. Berthoumieu (1904, p. 30) reported the species ‘ Hoplismenus ovatus Cress’. for Mexico. We are not aware of Cresson having used the name ovatus for a species in this insect group, and all other circumstances suggest that Berthomieu must have had H. ornatus in mind. Therefore, and in agreement with Townes (1944, p. 314), we regard H. ovatus as an incorrect subsequent spelling of Hoplismenus ornatus Cresson, 1868 (ICZN 1999, Article 33.3). Yu et al.

Tropicolabus Heinrich, 1959 Tropicolabus Heinrich, 1959: 216. Type species Platylabus foxi Davis, 1898, by original designation. Comparative diagnosis Heinrich (1959, p. 216), and later Heinrich (1962b, p. 754), specified that Tropicolabus differed from Platylabus because of the ‘upwards curbed [sic] apophyses of the propodeum’, a character shared instead with Ambloplisus. After a careful examination of the type species and the first female, it is safe to conclude that the upward apophyses are in fact simply tooth-like projections formed by the conjunction of the strongly lamellate propodeal carinae (Figure 37b). This character can be seen in several other Platylabini species (e.g. Platylabus clarus), and does not constitute apophyses as in the case of Ambloplisus ornatus (Figure 37a) or as delineated by Ronquist and Nordlander (1989). Therefore, the primary diagnostic character proposed by Heinrich (1959) during the establishment of the new genus does not allow an unambiguous separation between Tropicolabus and Platylabus. However, we do not feel the need to synonymise the two genera (and therefore restore the original combination for the species), to avoid further complications within the tribe. For the purpose of this contribution, Tropicolabus can be easily separated from Platylabus employing other characters, one of which was not previously mentioned by Heinrich (1959, 1962b). According to our examination, Tropicolabus can be distinguished from Platylabus by the following combination of characters: presence of twisted mandibles, appearing unidentate in frontal view (bidentate in Platylabus); the predominantly smooth and shining mesoscutum, with dense punctures only in the anterior half (Figure 36b); and lamellate propodeal carinae (Figure 37b) (never lamellate in Platylabus). The misinterpretation of the propodeal tooth-like projection also impacts the separation between Tropicolabus and Ambloplisus, which can now be easily distinguished by the following characters: the tooth-like propodeal carinae (Figure 37b) (and not long apophyses as in Aploplisus, Figure 37a); the strongly impressed gastrocoeli and thyridia as large as or larger than the space between them, the strong and large gastrocoeli (Figure 36c) (superficial and small in Amploplisus, Figure 5d); the broad genae in frontal view (Figure 38b) (convergent in Ambloplisus, Figure 38a); temples roundly narrowed in dorsal view (Figure 39b) (steeply, almost concavely narrowed in Ambloplisusi, Figure 39a) the propodeum with the area superomedia separated from the area basalis (Figure 37b) (a single elongate area in Ambloplisus, Figure 5c). Range and diversity The genus is monotypic and, so far, has been recorded only in the Nearctic, even though some comments in Santos et al. (2021, supplement S8) seem to confirm its presence in Costa Rica (unpublished material). Heinrich (1962b, p. 755) already hypothesised a more tropical distribution of the genus based on the rich yellow colour pattern on the thorax, typical of Neotropical species. Prior to this contribution, the genus was known only for the north-eastern United States and only from the type locality., Published as part of Dal Pos, Davide, Heilman, Victoria & Welter-Schultes, Francisco, 2022, Platylabini (Hymenoptera: Ichneumonidae: Ichneumoninae) of the south-eastern United States: new distributional data, taxonomic notes, illustrated keys, and an annotated catalogue of the genera and species, pp. 1869-1938 in Journal of Natural History 56 on pages 1925-1927, DOI: 10.1080/00222933.2022.2134061, http://zenodo.org/record/7397619, {"references":["Heinrich G. 1959.

Original type series Lecotype ♀ (originally described as ♂ by Cresson (1864), see below) (ANSP). Cresson (1864, p. 288) described Hoplismenus thoracicus from ‘Hab.– Pennsylvania. Mr.Tryon Reakirt [= collected by Mr.Tryon Reakirt]’ reporting it as a male but without specifying the number of specimens included in the description. Cresson (1916, p. 59), in his list of types, reported the lectotype having the ‘Left antenna off’. Townes (1944, p. 316) and Townes and Townes (1951, p. 282) did not specify any number of specimens, but simply reported the information given in the literature. Later on, Heinrich (1962b, p. 780) referred to the specimen as the ‘Holotypus’, highlighting the fact that the actual sex is female and not male. Carlson (1979, p. 317) stated that Cresson (1916, p. 1) ‘indicated which single specimen was to be regarded as the type for each; thus he selected lectotypes for those cases in which he had described a species from more than one specimen’. Hopper (1984, p. 968) reported being unable to see how it can be claimed that Cresson (1916) indicated a single specimen to be the type. This statement contradicted Cresson’s (1916) own statement that ‘In selecting the single type the author has been governed by the present condition of the original material, and has always selected the perfect, or more nearly perfect specimen’ and suggests that Hopper (1984) overlooked this clear indication of Cresson’s (1916) intention of selecting a single name-bearing type (i.e. a lectotype in the modern sense). Cresson’s (1916) lectotype designation was valid and no subsequent lectotype designation has any validity (ICZN 1999, Article 74.1.1). The fact that the selected specimen eventually could no longer be traced, as suggested by various subsequent authors (Heinrich 1962b, p. 780; Hopper 1984), could be explained by collection mismanagement and has no influence on the validity of the lectotype selection. Only a careful study of Cresson’s collection can provide more insights. Moreover, the mismatch between the original sex description by Cresson (1916, p. 59) (male) and the observation of a female by Heinrich (1962b, p. 780) is troubling. Hopper (1984, p. 968) experienced a similar situation when, looking at Cresson’s type housed at ANSP and stored in a separate case, he found a mismatch of sexes between the original description and the segregated specimen. Apparently, the two former curators of the collection had personally hand-picked the specimens from the original type series and stored them in a different drawer, and because they both worked on different taxa, they were not skilled in identifying the sex of Ichneumonidae (Hopper 1984, p. 968). Therefore, there is a real possibility that the original description contained more than one specimen and that the curators at ANSP selected only one specimen that later was regarded as the ‘holotype’ by Heinrich (1962b, p. 780). Only a careful study of Cresson’s collection can resolve the issue. Type locality United States of America, Pennsylvania.

Host Although host records for the subspecies thoracicus are unknown, the nominate subspecies (Europe) is a parasitoid of Geomemetridae (Lepidoptera) (Shaw et al. 2015). Male The first description of a male was provided by Heinrich (1956, p. 651). However, Heinrich (1956, p. 651) did not realise the problem with the sex of the syntypes (see above, Type series), and believed he had described the female for the first time. Comments The species Linycus exhortator (Fabricius, 1787) is represented by three subspecies, one with a European distribution (the nominotypical subspecies), and the other two occurring in the Nearctic (Heinrich 1962b, p. 780). Of these two, only one occurs in the south-eastern United States, L. exhortator thoracicus. Unfortunately, there are some issues regarding the state distribution of this latter subspecies within the US. Townes and Townes (1951, p. 282) reported only three states for the distribution of the subspecies, namely New York, Pennsylvania and Rhode Island. Yu et al. (2016) did not report Rhode Island in their catalogue. Another issue revolves around Carlson (1979, p. 542). In his catalogue, the author mentioned the species as occurring from ‘ Maine s. to Va., w. to Wis. And Mo’. This distribution probably stems from the idea already advanced by Heinrich (1977, p. 279) that the taxon is probably widespread throughout the eastern part of the country, ‘From Michigan and Ontario south to Georgia and Tennessee’. However, these statements are too vague and inconsistent, and it is not clear whether they are substantiated by any specimens. Therefore, we are not considering Heinrich’s (1977) and Carlson’s (1979) vague statements to represent valid distributional records – even though they are very probably true. The records from Massachusetts and Ohio are from BugGuide and identified by Carlson (2010a, 2013) as Linycus exhortator., Published as part of Dal Pos, Davide, Heilman, Victoria & Welter-Schultes, Francisco, 2022, Platylabini (Hymenoptera: Ichneumonidae: Ichneumoninae) of the south-eastern United States: new distributional data, taxonomic notes, illustrated keys, and an annotated catalogue of the genera and species, pp. 1869-1938 in Journal of Natural History 56 on pages 1893-1895, DOI: 10.1080/00222933.2022.2134061, http://zenodo.org/record/7397619, {"references":["Cresson ET. 1864.

Cyclolabus Heinrich, 1935 Cyclolabus Heinrich, 1935: 198. Type species: Platylabus nigricollis Wesmael, 1845 by original designation. Comparative diagnosis From all the other four Nearctic Platylabini genera with small circular or roundish propodeal spiracles – Apaeleticus, Carlsonia, Cyclolabus and Linycus – Cyclolabus can be easily distinguished by: the strongly pronounced gastrocoeli; thryidia larger than the space between them; and the presence of distinct propodeal carinae (Figure 10). Cyclolabus is also morphologically similar to Platylabus Wesmael, 1845, mainly differing from it by the presence of small and circular propodeal spiracles (Figure 22) (Heinrich 1961, 1962b; Tereshkin 2009). However, as already noted by Heinrich (1962b), the small species of Platylabus can also possess roundish and relatively small spiracles, rendering the demarcation of the two genera ambiguous for certain specimens. In these latter cases, the observation of other characters is necessary, and we have listed them under the genus Platylabus. Range and diversity Cyclolabus has a worldwide distribution, with 11 species in the Nearctic and only two species occurring in the south-eastern United States (Heinrich 1961, 1962b; Yu et al. 2016).

Tribe Platylabini Berthoumieu 1904 (Ichneumonidae, Ichneumoninae) Traditionally, the diagnostic traits used to identify the tribe Platylabini have been the following: (1) a convex clypeus; (2) first metasomal tergite broader than high with postpetiole dorsally strongly flattened; and (3) amblypygous metasoma in females (Heinrich 1961, 1967a, 1967b; Townes et al. 1961; Tereshkin 2009). However, as extensively discussed by Santos et al. (2021, supplement S8) the tribe, as above defined, excludes at least two genera well nested within the tribe: Probolus Wesmael, 1845, and Cotiheresiarches Telenga, 1929. The authors concluded that, for the moment, it is impractical to provide a succinct diagnosis of the tribe and, with a couple of exceptions (Eurylabus Wesmael, 1845 and Levansa Townes, 1961), all the Ichneumoninae with a flattened petiole are surely Platylabini. Even though more in-depth morphological analyses will be necessary to better delineate the diagnosis of the tribe, we also believe that a practical key to the tribes and to the Platylabini genera can facilitate identification., Published as part of Dal Pos, Davide, Heilman, Victoria & Welter-Schultes, Francisco, 2022, Platylabini (Hymenoptera: Ichneumonidae: Ichneumoninae) of the south-eastern United States: new distributional data, taxonomic notes, illustrated keys, and an annotated catalogue of the genera and species, pp. 1869-1938 in Journal of Natural History 56 on page 1873, DOI: 10.1080/00222933.2022.2134061, http://zenodo.org/record/7397619, {"references":["Berthoumieu V. 1904.

Host Unknown. Male Described by Heinrich (1962b, p. 730) in the original description, based on a single male that he designated as allotype. The other two known male specimens of the species are from Newfoundland and Labrador, recorded by Heinrich (1975, p. 774). Comments Platylabus opaculus Thomson, 1888, is split in two subspecies, one with European distribution (the nominotypical subspecies), and the other occurring in the Nearctic (Heinrich 1962b, p. 730). According to Heinrich (1962b, p. 730), the only difference between the two is the colour of the legs, which are entirely black in Platylabus opaculus opaculus and rufous in Platylabus opaculus americanus. The records from Massachusetts are from BugGuide and identified by Carlson (2010b) as Platylabus opaculus. However, these have not been recorded in any paper or catalogue (see Yu et al. 2016). The new record for North Carolina is based on a female specimen found at the FSCA that Townes identified as Platylabus opaculus americanus in 1967, which DDP double checked, confirming Townes’ identification. The record has never been reported in any paper or catalogue (cf. Yu et al. 2016), and apparently Heinrich (1975) was not aware of it since no mention of it appears in his paper. The record of Platylabus opaculus americanus for North Carolina also marks the southernmost distributional record for the subspecies and the first for the south-eastern United States (Figure 22b)., Published as part of Dal Pos, Davide, Heilman, Victoria & Welter-Schultes, Francisco, 2022, Platylabini (Hymenoptera: Ichneumonidae: Ichneumoninae) of the south-eastern United States: new distributional data, taxonomic notes, illustrated keys, and an annotated catalogue of the genera and species, pp. 1869-1938 in Journal of Natural History 56 on pages 1911-1913, DOI: 10.1080/00222933.2022.2134061, http://zenodo.org/record/7397619, {"references":["Heinrich G. 1962 b.

Provancher (1882, p. 329) described ‘ Platylabus Rubri Capensis ’ from Québec without specifying the number of specimens included in the description. Gahan and Rohwer (1918a, p. 168) designated the lectotype, addressing it as ‘Type– Female, yellow label 717. 2nd Coll. Pub. Mus., Quebec’. Subsequently, Heinrich (1962b, p. 774) incorrectly employed the term ‘Holotypus’ for the same specimen. Barron (1975, p. 546) considered valid the designation of Gahan and Rohwer (1918a, p. 168). b) Habitus, lateral view. c) Head, frontal view. d) Labels. Type locality Canada, Québec, ‘Cap-Rouge’. No type locality is given on the lectotype labels or in the original description, but the species has been described as ‘Platylabe du-CapRouge’ (= Platylabus from Cap-Rouge). Cap-Rouge is a former city in central Québec. Type specimens examined (Figure 30) Holotype: ‘[Yellow label] 717/[White label] Platylabus / rubricapensis /Prov. // [Red label] LECTOTYPE / PLATYLABUS /RUBRI CAPENSIS/ Provancher 717/ Gahan & Rohwer ’15/Barron ‘71’ (images examined).

Host Unknown. Male The first description of a male was provided by Heinrich (1975, p. 774), who referred to the specimen as the neallotype. Comments Townes and Townes (1951, p. 281) recorded the species for Québec, New York and North Carolina. However, as noted by Heinrich (1962b, p. 712), these last two state records refer to Platylabus rubristernatus Heinrich, 1962b (see below). The correct first record for New York must be attributed to Heinrich (1962b, p. 712), while the species has yet to be recorded for North Carolina. Yu et al. (2016) failed to list the type locality (Québec) and all the records provided by Heinrich (1962b, p. 712) and Carlson (1979, p. 545) among the distribution locality of the species. Provancher (1882) described the species under the name ‘ Rubri Capensis ’. Carlson (1979, p. 545) considered it an ‘invalid’ name because it was not binomial, and proposed the use of Platylabus rubricapensis Provancher, 1886, since the redescription contained a ‘valid binomen’. Subsequent authors kept using rubricapensis Provancher, 1882 as a valid authorship without adding any reason for rejecting Carlson’s (1979) observation (Yu and Horstmann 1997; Yu et al. 2016). We hereby provide a rationale to solve the confusion. Firstly, Carlson (1979) used the term ‘invalid’; however, the name would have been unavailable rather than invalid (see differences between Chapters 4 and 6 of ICZN (1999)). Secondly, the two words together refer to a single entity (i.e., from Red Cape (= Cap Rouge, Québec, Canada)) and are accepted to form a species-group name; they are deemed to form a single word and are united without a hyphen (rubricapensis) (ICZN 1999, Articles 11.9.5 and 32.5.2.2). Therefore, Platylabus rubricapensis Provancher 1882 is an available name., Published as part of Dal Pos, Davide, Heilman, Victoria & Welter-Schultes, Francisco, 2022, Platylabini (Hymenoptera: Ichneumonidae: Ichneumoninae) of the south-eastern United States: new distributional data, taxonomic notes, illustrated keys, and an annotated catalogue of the genera and species, pp. 1869-1938 in Journal of Natural History 56 on pages 1916-1918, DOI: 10.1080/00222933.2022.2134061, http://zenodo.org/record/7397619, {"references":["Provancher L. 1882.

Original type series Syntypes ♀ of Ichneumon detritus (MNHN); lectotype ♂ of Amblyteles illaetabilis (ANSP); lectotype ♀ of Ichneumon indistictus, designated by Gahan and Rohwer (1917, p. 306) (LUEC). Brullé (1846, p. 302) described Ichneumon detritus without specifying the number of specimens included in the description. Townes (1944, p. 376) and Townes and Townes (1951, p. 283) did not specify any number of specimens either. Later on, Heinrich (1962a, p. 519) referred to the specimen as the ‘Holotypus’. Heinrich’s (1962a, p. 776) employment of the term ‘holotypus’ did not constitute a valid lectotype designation (ICZN 1999, Article 74.5). In this paper, we decided to take a more conservative approach, referring to the specimen(s) as ‘syntypes’ ICZN (1999, Article 73.2). Cresson (1877, p. 190) described Amblyteles illaetabilis without specifying the number of specimens included in the description. Cresson (1916, p. 35), in his list of types, simply reported the type to be a male from Georgia and ‘In good condition’, without clarifying the number of specimens. Townes (1944, p. 319) and Townes and Townes (1951, p. 283) did not specify any number of specimens either. Later on, Heinrich (1962a, p. 519) referred to the specimen as the ‘Holotypus’. Carlson (1979, p. 317) stated that Cresson (1916) ‘indicated which single specimen was to be regarded as the type for each; thus he selected lectotypes for those cases in which he had described a species from more than one specimen’. Hopper (1984, p. 968) reported being unable to see how it can be claimed that Cresson (1916) indicated a single specimen to be the type. This statement contradicted Cresson’s (1916, p. 1) own statement that ‘In selecting the single type the author has been governed by the present condition of the original material, and has always selected the perfect, or more nearly perfect specimen’. Furthermore, it suggests that Hopper (1984) overlooked this clear indication of Cresson’s (1916) intention of selecting a single name-bearing type (i.e. a lectotype in the modern sense). Cresson’s (1916) lectotype designation was valid and no subsequent lectotype designation has any validity (ICZN 1999, Article 74.1.1). The fact that the selected specimen eventually could no longer be traced, as suggested by various subsequent authors (Heinrich 1962b, p. 780; Hopper 1984), could be explained by collection mismanagement and has no influence on the validity of the lectotype selection. Only a careful study of Cresson’s collection can provide more insights. Heinrich’s (1962a, p. 519) employment of the term ‘holotypus’ was in errror. Provancher (1875, p. 75) described Ichneumon indistinctus from Québec without specifying the number of specimens included in the description. Gahan and Rohwer (1917, p. 306) designated the lectotype, addressing it as ‘Type– Female, yellow label 185. 2nd Coll. Pub. Mus., Quebec’. Subsequently, Heinrich (1962a, p. 519) incorrectly employed the term ‘Holotypus’ for the same specimen. Barron (1975, p. 487) considered valid the designation of Gahan and Rohwer (1917, p. 75). Type locality United States of America, ‘la Caroline’ (Ichneumon detritus), Georgia (Amblyteles illaetabilis); Canada, Québec (Ichneumon indistinctus). Brullé (1846, p. 304) reported Ichneumon detritus for ‘la Caroline’. The same author, when reporting the locality for Ephialtes irritatus Fabricius, stated ‘l’Amérique du Nord (la Caroline)’. It is not clear what Brullé (1846, p. 304) was referring to with ‘la Caroline’ – possibly the region encompassed by the two Carolinas (North and South).

Host Unknown. Male The syntypes of Amblyteles illaetabilis Cresson, 1877 are males and thus their description functions as a description of the male. Moreover, Heinrich (1962a, p. 520) also provided a description of the males. Comments The taxonomic history of detritus is complicated. Cresson (1877, p. 192) synonymised Ichneumon syphax Cresson, 1864 under Amblyteles detritus (Brullé, 1846). Conversely, Townes (1944, p. 376) transferred syphax under the genus Ctenichneumon, and synonymised detritus under syphax disregarding that detritus was the senior name that should have had precedence (ICZN 1999, Article 23.1). In the same work, Townes (1944, p. 319) maintained as valid both illaetabilis and indistinctus, transferring them under the genus Probolus. This view was followed by Townes and Townes (1951, p. 283, 296). After Townes (1961, p. 107) examined the syntypes at MNHN, detritus was resurrected and transferred to the genus Probolus, treating Amblyteles illaetabilis as its synonym. Heinrich (1962a, p. 519) followed Townes’ (1961, p. 107) view, but treated indistictus as a synonym of Probulus expunctus (Cresson, 1864). It was Barron (1975, p. 487) who, based on the original type series of indistinctus, recognised indistictus as junior synonym of detritus instead of expunctus., Published as part of Dal Pos, Davide, Heilman, Victoria & Welter-Schultes, Francisco, 2022, Platylabini (Hymenoptera: Ichneumonidae: Ichneumoninae) of the south-eastern United States: new distributional data, taxonomic notes, illustrated keys, and an annotated catalogue of the genera and species, pp. 1869-1938 in Journal of Natural History 56 on pages 1921-1924, DOI: 10.1080/00222933.2022.2134061, http://zenodo.org/record/7397619, {"references":["Brulle GA. 1846.

Gahan and Rohwer (1918a, p. 168) designated a lectotype, but as Barron (1975, p. 523) acknowledged, there is no need for a lectotype as Provancher clearly mentioned only one specimen. Therefore, this specimen is here referred to as the holotype fixed by monotypy (ICZN 1999, Article 73.1.2) and Gahan and Rohwer’s (1918a, p. 168) designation should be considered an invalid lectotype designation.

Male The first description of a male was provided by Heinrich (1962b, p. 747), who referred to the specimen as the neallotype. Comments Bradley (1978, p. 16, fig. 11 reported the species from ‘Newfoundland to British Columbia’, plotting the records on a map without pointing out the Canadian provinces. This is probably why subsequent authors (Carlson 1979; Yu and Horstmann 1997; Yu et al. 2016) did not report the species occurring in Manitoba and Nova Scotia. Yu et al. (2016) also failed to report California and Washington, reported by Townes and Townes (1951, p. 281), as state records for the species. According to Heinrich (1962b, p. 748), these western populations are slightly less melanistic than the eastern ones and could also be interpreted as different subspecies., Published as part of Dal Pos, Davide, Heilman, Victoria & Welter-Schultes, Francisco, 2022, Platylabini (Hymenoptera: Ichneumonidae: Ichneumoninae) of the south-eastern United States: new distributional data, taxonomic notes, illustrated keys, and an annotated catalogue of the genera and species, pp. 1869-1938 in Journal of Natural History 56 on pages 1913-1915, DOI: 10.1080/00222933.2022.2134061, http://zenodo.org/record/7397619, {"references":["Provancher L. 1875.

Updated distribution (Figure 21) UNITED STATES OF AMERICA: Arkansas (Heinrich 1977), Florida (new state record), Georgia (Heinrich 1972), Louisiana (Heinrich 1972), Mississippi (Heinrich 1971), Tennessee (Heinrich 1977). Host Unknown. Male The first description of a male was provided by Heinrich (1972, p. 210), who referred to the specimen as the neallotype. Comments Heinrich (1971, p. 1025) described the genus Neolinycus and the species N. michaelis based on a single female from Mississippi (Figure 17). The same author, a year later, described a new subspecies, Neolinycus michaelis georgianus Heinrich, 1972, based on a female from Georgia that was ‘Chromatically strikingly different, particularly by color of mesoscutum and pleuron’ (Figure 18) (Heinrich 1972, p. 210). According to Heinrich (1972), N. michaelis georgianus differs from the nominotypical subspecies by the following characters: black mesoscutum (orange in michaelis); longitudinal white lines running across the mesoscutum (small and reduced in michaelis); mostly orange pleura (mostly white in michaelis); white prescutellar carinae (orange in michaelis). In the same work, he also described the male of N. michaelis michaelis for the first time, acknowledging the presence of slight infuscation of the metasoma on tergites 2–5, and the different colouration of the mesoscutum, with the lateral lobes black and the median lobe orange. Later on, Heinrich (1977, p. 282) proposed another new subspecies, Neolinycus michaelis arkansae, this time based on two male specimens from Arkansas (Figure 19), that differ from the other two subspecies by: the entirely black mesoscutum (character revised below); the black bands on metasoma covering more than half of 2–5 tergites; the mostly white mesopleuron; prescutellar carinae not white marked. The differences among all these subspecies are summarised in Table 1. Carlson (1979, p. 542) synonymised N. michaelis georgianus without providing any evidence or comments for the new proposed treatment and failed to list N. michaelis arkansae in his catalogue of Ichneumoninae of North America. It is not clear whether Yu et al. (2016) reocrded Carlson’s (1979) treatment and considered the subspecies georgianus to be a synonym. Reading Heinrich (1972, 1977), it is pretty clear that the author’s subspecies hypotheses are mostly based on two factors: colour pattern and distribution. After studying the type specimens of the different subspecies, we realised that the ‘entire mesoscutum black’ that Heinrich (1977, p. 282) listed among the characters important for the separation of N. michaelis arkansae from the other two subspecies is incorrect: two reduced white stripes are clearly present on the mesoscutum, and the pin simply obscures part of them (Figure 19a). The character has been revised in Table 1. Moreover, we have also analysed several specimens of Neolinycus from Florida and Georgia, and the same specimens that Porter (2003) examined and wrongly identified as Cyclolabus carolinenesis Heinrich, 1962. Because of this new material, we provide here three lines of evidence that, when analysed together, falsify the subspecies concepts proposed by Heinrich and that support both Carlson’s (1979) synonymisation and the establishment of a further new junior synonym N. michaelis michaelis = N. michaelis arkansae. The first evidence derives from the observation of specimens that have a colour pattern halfway between the purportedly different subspecies. For instance, a male specimen from Florida has tergites 2–5 of the metasoma infuscate (condition considered diagnostic for N. michaelis michaelis) but associated with a complete black mesoscutum with well-developed longitudinal white lines (condition considered diagnostic for N. michaelis georgianus) (Figure 20a–b). Nine male specimens have very reduced longitudinal white lines on the mesoscutum that are partially red (median lobe) and partially black (lateral lobes) (typical of males of N. michaelis michaelis) but with black bands covering more than half of tergites 2–5 (typical of N. michaelis arkansae) (Figure 20c–d). Eight other females fitting the colour pattern expected for the latter subspecies were collected among male specimens with colour pattern halfway between N. michaelis georgianus and N. michaelis arkansae. The second line of evidence is composed of specimens collected in the ‘wrong range’ – that is, the range expected/ascertained/assumed to be that of the other subspecies. This is the case for four males that correspond to the holotype of N. michaelis arkansae and were collected in Georgia, which is the typical range of N. michaelis georgianus. The third line of evidence is composed of specimens well matching with the colour pattern expected for two different subspecies but collected together in the same location. This is the case for a female that agrees chromatically with the definition of N. michaelis michaelis by having an orange mesoscutum with very reduced white longitudinal stripes but was collected in Florida among specimens matching the colour pattern of N. michaelis georgianus (Figures 20e–f). From all the above evidence, it is clear that a continuum in colour pattern and distribution exists, and the subspecies cannot be unequivocally differentiated based either on consistent morphological traits or on clear distributional patterns. Therefore, we hereby regard for the first time N. michaelis arkansae as a junior synonym of N. michaelis michaelis and confirm the synonymisation by Carlson (1979) of N. michaelis georgianus with N. michaelis michaelis. Heinrich (1971, p. 1025) reported Michael Horan as the collector of the type for N. michaelis. There is no collector information on the labels (Figure 17c). Heinrich (1972, p. 210) reported F. Naumann as the collector of the type for N. michaelis georgianus.

The rediscovery of the holotype of Stephanus (Distephanus) [sic!] athesinus Biegeleben, 1929, preserved in the collections of the Museo di Storia Naturale, Venice (Italy), is recorded together with a redescription and a comment on its taxonomic identity. Therefore, its synonymy with Megischus anomalipes (Förster, 1855) is confirmed. New distributional data for M. anomalipes is provided: it is recorded for the first time from the Italian regions of Veneto, Emilia-Romagna, Tuscany and Basilicata, and newly recorded from Greece.

The genus Saotis Förster, 1869, with its species Saotis mirabilis Schmiedeknecht, 1914, is hereby recorded for the first time from Italy.

Zombrus bicolor (Enderlein, 1912) is recorded from new and further sites in Tuscany, far from the previous and only record, suggesting its establishment in Italy.

Ibalia jakowlewi Jacobson, 1899 is hereby recorded for the first time for Italy, based on three specimens collected in the Veneto region, which in turn represent the first record of the subgenus Tremibalia Kierych, 1973 for Italy. Some ecological notes based on the circumstances of their sampling are also reported.
