Two new species of Harpalyce are described from Cuba, H. revolutasp. nov. from a serpentine area in the northern part of E. Cuba and H. marianensissp. nov. from calcareous areas in the southern part of E. Cuba. Both have relatively small flowers, with an up to 6 mm long standard, and 2–3 mm long wings. Harpalyce marianensis is further characterized by strongly suberous (corky) young branches of a spongy consistence, deeply furrowed longitudinally, and by leaflets covered with a particular type of orange, apparently disk-shaped, sessile glands abaxially. Harpalyce revoluta, moreover, has suborbicular or broadly elliptic leaflets with a strongly recurved or sometimes revolute margin, secondary veins inconspicuous on either side; the foliar glands, by their morphology and anatomy, are of a different type. An epitype is designated for the name Harpalyce and its type, H. formosa; the distribution of both new species and their close relatives is mapped, and an updated identification key is offered, to cater for all 16 currently recognised Cuban species.

Two new species, Urodeta falcatasp. nov. from Ghana and U. bisignasp. nov. from Democratic Republic of the Congo are described. The habitus and genitalia are diagnosed and illustrated in detail. Identification keys to the Afrotropical species of the genus Urodeta, based on male and female genitalia, are provided.

Elachista karsticola Varenne & Nel, 2018 Elachista karsticola Varenne & Nel, 2018: 6, figs. 10–11. Examined material. Holotype Ƌ: France, Alpes-Maritimes, Courségoules, 950 m, 12.IV.2017, Th.

(Fig. 10) Remarks. Elachista karsticola was described from a male holotype and separated from the randomly selected species of the E. bifasciella species-group E. sebastella Kaila, 2015, E. sulcsiella Savenkov, 2013, E. orstadii Palm, 1943 and E. gruenewaldi Parenti, 2002 on genitalia characters (Varenne & Nel 2018). The species was recently included in the World Catalogue of Elachistidae as valid taxon (Kaila 2019). However, the successfully sequenced holotype shares the barcode with E. maculosella, a species described from France and corresponding in morphology but not considered as potential conspecific by Varenne & Nel (2018).According to Kaila (pers. comm.) the taxon falls in the range of intraspecific variation of E. maculosella. We therefore synonymize E. karsticola with E. maculosella.

Elachista bidentata was described from a male holotype and separated from E. orstadii on subtle differences in genitalia (Varenne & Nel 2019). However, the DNA barcode sequence of the holotype fully corresponds with the latter species and the alleged genitalia differences are within the intraspecific variation of large samples from Europe and Siberia (Kaila in litt.). We therefore synonymize E. bidentata with E. orstadii.

The worn specimen with overall white appearance was compared with other superficially similar looking species (Nel & Varenne 2019a) but not with the morphologically closest species E. bedellella (Sircom, 1848) (Kaila in litt.). We have been able to obtain a short sequence of the holotype with 259bp which, however, corresponds to E. squamosella (Duponchel, 1843) with 99.6% similarity. The latter species is quite different externally and in genitalia morphology and similarity in DNA barcode may be due to the short sequence. E. rosseloensis was not considered in the almost simultaneously published World Catalogue of Elachistidae (Kaila 2019)., Published as part of Huemer, Peter & Van Nieukerken, Erik J., 2021, Identity of some recently described Lepidoptera from France-re-assessed with DNA barcodes and morphology, pp. 301-337 in Zootaxa 4941 (3) on page 330, DOI: 10.11646/zootaxa.4941.3.1, http://zenodo.org/record/4595123, {"references":["Nel, J. & Varenne, T.

Seventy-three species of Lepidoptera described from France since 2000, particularly by Jacques Nel and Thierry Varenne, are re-assessed from largely unpublished molecular data. We tried to obtain DNA barcode sequences from 62 holotypes, supplemented by paratypes of eight species and on one case by non-type material, whereas one previously synonymized species was not sequenced. Altogether we obtained 78 DNA barcode sequences for 65 nominal taxa while sequencing failed for six holotypes. An integrative analysis from molecular data and morphology supports the validity of the majority of species but also resulted in the re-assessment of several taxa. The following 13 new synonymies are established: Stigmella cyrneorolandi Nel & Varenne, 2013 syn. nov. of Stigmella rolandi van Nieukerken, 1990; Stigmella thibaulti Varenne & Nel, 2019 syn. nov. of Stigmella nivenburgensis (Preissecker, 1942) (Nepticulidae); Nemapogon peslieri Varenne & Nel, 2017 syn. nov. of Nemapogon inexpectata Varenne & Nel, 2017 (Tineidae); Phyllonorycter acericorsica Varenne & Nel, 2015 syn. nov. of Phyllonorycter ochreojunctella (Klimesch, 1942) (Gracillariidae); Ancylis paraobtusana Varenne, Nel, & Peslier, 2020 syn. nov. of Ancylis comptana (Frölich, 1828) (Tortricidae); Celypha paludicolella Varenne & Nel, 2017 syn. nov. of Celypha doubledayana (Barrett, 1872) (Tortricidae); Cydia oxytropidana Nel & Varenne, 2016 syn. nov. of Cydia oxytropidis (Martini, 1912) (Tortricidae); Sorhagenia orocorsa Varenne & Nel, 2016 syn. nov. of Sorhagenia janiszewskae Riedl, 1962 (Cosmopterigidae); Chionodes cerdanica Peslier, Nel & Varenne, 2020 syn. nov. of Chionodes distinctella (Zeller, 1839) (Gelechiidae); Elachista bidentata Varenne & Nel, 2019 syn. nov. of Elachista orstadii Palm, 1943; Elachista karsticola Varenne & Nel, 2018 syn. nov. of Elachista maculosella Chrétien, 1896 (Elachistidae); Scythris chablaisensis Delmas, 2018 syn. nov. of Scythris laminella ([Denis & Schiffermüller], 1775) (Scythrididae); Epermenia pumila (Buvat & Nel, 2000) syn. nov. of Epermenia profugella (Stainton, 1856) (Epermeniidae). Finally, the status of some taxa still remains unclear due to the lack of DNA barcodes of closely related species and the absence of convincing diagnostic characters in morphology.

Biselachista zonulae Sruoga, 1992 (Abb. 1) Bei einem Ausflug am 24. Juli 2018 in die Region Arosa (GR) fand der Erstautor in einer steilen Bergwiese im Furggatobel auf 2170 m. ü.M. einen vorerst unbestimmten Kleinschmetterling. Aufgrund der geringen Spannweite von 5 mm und der Gesamtmorphologie wurde eine Zuordnung zur Familie Elachistidae vermutet. Eine genitalmorphologische Untersuchung führte zu Biselachista zonulae. Diese Art wurde aus den zentralasiatischen Gebirgen von Kasachstan, Kirgisistan und Tadschikistan beschrieben (www.lepiforum.de). In Europa wurde sie in den Gebirgen der Slowakei, in Polen (Tokár et al. 1999), Österreich (Huemer 2013), Frankreich (Kaila & Varalda 2004) und in Deutschland gefunden. Im Rahmen eines Arbeitstreffens von Kleinschmetterlings-Spezialisten der Schweiz konnte die Bestimmung nicht restlos bestätigt werden. So wurden Bilder des Belegtieres und des Genitalpräparates an den Spezialisten Lauri Kaila aus Finnland gesendet. Mit E-Mail vom 18. Februar 2019 bestätigt Lauri Kaila die Bestimmung von Biselachista zonula e. In seiner Privatsammlung konnte der Drittautor ein weiteres Belegtier aus Riein (GR) finden. Auch dieses Tier wurde von Lauri Kaila als zu B. zonulae gehörig bestätigt. Fundorte: CH-Riein (GR), 1320 m. ü.M., 12.07.2001, leg.

The genus Gielisella gen. n., belonging to the Elachistidae: Parametriotinae is described with two new species from southern Spain: its type species G. clarkeorum sp. n. and G. nigripalpis sp. n., both only known from adults collected at light. DNA barcodes of both species are provided. The taxonomic history of the Parametriotinae is discussed and a catalogue of the 35 recognised genera is provided as appendix. The arguments for erecting a new genus are discussed and we hypothesize that this constitutes an overlooked native Palaearctic element, although we cannot completely rule out the possibility of imported exotic species.

Seven first records and one confirmation of old records for the Lepidotera fauna of Switzerland (Lepidoptera: Elachistidae, Gelechiidae, Tortricidae, Pyralidae)Seven microlepidoptera are reported as new for Switzerland:ElachistahedemanniRebel, 1899,Chionodescontinuella(Zeller, 1839),Gynnidomorphaalismana(Ragonot, 1883),Pelochristahuebneriana(Lienig & Zeller, 1846),Cydiailipulana(Walsingham, 1903),Hypochalciadignella(Hübner, 1796) andEuchromiusbella(Hübner, 1796). An other species, so far known only from old records on the Swiss checklist, is also reported:Aplotanigricans(Zeller, 1852).

Elachista pellineni Sruoga & Kaila sp. nov. urn:lsid:zoobank.org:act: 2D8B8809-389A-486E-B79A-6EA153 F34425 Figs 24���39 Diagnosis Elachista pellineni Sruoga & Kaila sp. nov. is a small species with peculiarly coloured forewings (Figs 24, 35) and dorsoventrally flattened head. In wing pattern and male genitalia, the new species is comparable to E. heteroplaca (for illustrations, we refer to Kaila 1998: figs 1���5) and E. oryx Sruoga & Kaila sp. nov., known from the same locality. However, E. pellineni Sruoga & Kaila sp. nov. is distinguishable by the much longer digitate processes, the juxta lobe strongly produced posteriorly and the wider uncus lobes. The female genitalia are very distinctive with the invagination of integument between sterna 7 and 8 densely filled with dark scales. Etymology The species named after Markku J. Pellinen, who collected the type material. Type material Holotype THAILAND ��� ♂; Lampang, Muban Phichai; 18��18��15�� N, 99��31��06�� E; 20 May 2013; M.J. Pellinen leg.; MZH VS2 / 23.11.18.

Remarks: The fragment of male genitalia illustrated by Clarke (1967) shows the shape of the phallus, with a large, keel-shaped manica. This is a feature typical of Stephensia and Perittia, not Elachista. The illustration also shows the shape of the juxta which is typical of several South American Perittia, P. regina Kaila, 2000 in particular (cf. Kaila 2000: 162). The characterization of the species as ‘brilliant’ is also a trait in P. regina.
