- Abstract
Mangabea troglodytes sp. nov. (Hemiptera: Heteroptera: Reduviidae: Emesinae) is described based on four specimens collected in a cave of the Namoroka Karstic System, Madagascar, and deposited in the Collection of the Muséum National d'Histoire Naturelle, Paris. The dorsal habitus as well as diagnostic characters of male and female genitalia are extensively illustrated and imaged. A key to species of the genus Mangabea Villiers, 1970 is provided and the degree of cave specialization of the new species is discussed.

Etymology. The name of the new species is the latinized form of the Greek noun φάντασμα, which means ‘ghost’, referring to the transparent, phantom-like appearance of the species. Noun in apposition. Habitat. The type locality is an abandoned human-made water mine locally known as ‘La Federica’, whose fauna and biological attributes have been described in detail in Suárez, Martín & Naranjo (2018) and Naranjo et al. (2018). The mine is divided in two parts: a west sector, in which oxygen levels are low and CO 2 is always higher than 10,000 ppm, and an east sector, in which the relative humidity is about 85%, but air conditions are more similar to those of the surface. All individuals of C. phantasma sp. nov. were hand collected from the floor of the east sector (Fig. 14), about 150 metres from the mine entrance. The landscape surrounding the mine consists of degraded thermo-sclerophyllous woodland, of Pistacia lentiscus L. and Olea cerasiformis Rivas-Mart. & del Arco.

The presence of Ploiaria domestica Scopoli, 1786 (Hemiptera: Heteroptera: Reduviidae: Emesinae) in Cyprus was considered doubtful. Hereby we report the first confirmed occurrence of this species in the island. Images of a living specimen and diagnostic characters for recognition of this species are provided. Whether this species has a native population in this island remains to be found.

THORAX (Figs. 7, 11���14): pronotum: anterolateral angles pronounced, rounded, diverging laterally; midlongitudinal sulcus shallow anteriorly, deep distally; transverse sulcus well defined; pronotum with shiny integument, margins of anterior lobe covered by dense, short blackish setae; in the disc, these setae sparser; anterior portion of posterior lobe with sparse, short setae, forming a midlongitudinal line in the hind lobe, where these setae are brighter, yellowish to whitish; disc smooth, with faint horizontal depression across humerus; humeral angles rounded, their margins slightly raised; humeral angles rounded; propleurae with acetabula produced laterally; stridulitrum attaining fore coxa; pleurae with blackish hairs, and small groups of adpressed whitish large setae on superior portion of mesopleura in some individuals; meso- and metasternum with patches of white wax, with whitish setae between coxae in few specimens; meso- and metaepisternum with whitish hairs. Scutellum subtriangular, apex blunt; acute in one specimen, with a few hairs in the central portion, reddish-brown or more darkened; sometimes with midlongitudinal line of whitish setae on approximately the first third, this is a continuation of the line of whitish setae on hind lobe. Legs: slender and elongate; coxae globose, slightly constricted apically; trochanters almost quadrangular; coxae and trochanters ventral with fine whitish hairs; femora thickened basally, mostly in fore and mid pairs, with sparse long straight blackish hairs; fore and mid femora with dense erect brush-like whitish setae ventrally; fore tibia with dense erect brush-like whitish setae ventrally, and small apical spur on anterior side of segment; all tibiae with sparse long straight blackish hairs too, and numerous erect setae, denser towards apex and in fore and mid tibiae. Tarsi three-segmented, densely setose, mainly on ventral surface. Hemelytra long, surpassing abdomen by about half length of membrane; corium covered with dense darkened bristle-like setae; cells and nervures of hemelytra and hind wing as Fig. 13. Abdomen: elongate; sternites with integument shiny with long whitish hairs; small patches, with variable dimensions, of whitish short setae on midlateral portions of first sternites in some specimens. MALE GENITALIA (Figs. 15���35): Pygophore blackish or brownish, with blackish hairs, longer in lateral portions, subpentagonal in ventral view (Figs. 15���16); with a rounded basal protuberance and subtriangular rounded apex (Figs. 15���16). Parameres blackish, symmetrical, elongated, with elongated blackish hairs on lateral margin and apex, where three or four elements are longer (Fig. 17). Phallus simple (Figs. 18���21); articulatory apparatus moderately short; with somewhat rounded arms (Figs. 19, 22, 25), or subsquared arms, these are more sclerotized (Fig. 23); dorsal phallothecal sclerite variably sclerotized, struts simple (Figs. 19, 26���27). After endosoma expansion, in two males, a conical projection of conjunctiva was observed at the apex (Fig. 20), whereas in the specimen from Paraguay, a similar conical projection of the conjunctiva is dorsal between endosoma processes and the apex of the phallothecal sclerite (Fig. 21); conjunctiva finely spiculose (Fig. 31). Among endosoma processes, in addition to diffuse basal thickening, a small, ventral, curved, and somewhat sclerotized process (Fig. 28) was followed, just above it, by another pair of small few sclerotized subrectangular processes (Fig. 28). These latter were subapical in one male (Fig. 28), apical in the male from Paraguay (Fig. 29), and apico-dorsal in another two males, in which these processes were dorsally located in relation to a group of numerous triangular, sclerotized processes (Fig. 30). These triangular processes could be better observed, after full endosoma expansion in the specimen in which they are located alone in the apex (Figs. 32���35). In the specimen from Paraguay, this group of triangular sclerotized processes was subapical. PLATE 4.

NOTES ON DISTRIBUTION : G. bicolor has been recorded from Brazil (Burmeister, 1838). However, the only detailed geographical data were given by St��l (1855, 1860, 1872), for the states of Minas Gerais and Rio de Janeiro. Berg (1879) collected this species in eastern Uruguay. NEW RECORD: Paraguay. NOTES ON ECOLOGY - BIOLOGY : Under natural conditions, a female of G. bicolor was found inside a corn field without information on the prey of this species. The offspring and adults were reared in the laboratory and fed with larvae of Spodoptera frugiperda (Smith, 1797) (Lepidoptera: Noctuidae) (Fig. 39), at different stages of development, as well as with larvae of other unidentified lepidopteran species. The only observed copula occurred in a dorsoventral position. Fertile eggs were laid together, displaying a round-shaped clutch. On the other hand, it was observed that females of G. bicolor also laid eggs without fertilization, but these latter were laid in a scattered manner, without showing a normal clutch shape. Five instars were observed before emergence of the adults. These are preliminary observations, and a complete description of the immature forms and biological data will be the subject of a future paper. Burmeister (1838) described Myocoris bicolor based on specimens from Brazil (Figs. 1���4). After some taxonomical changes as recorded above, and its inclusion in Graptocleptes by St��l (1872), the species has remained included in this genus ever since (Lethierry & Severin, 1896, Wygodzinsky 1949, Maldonado 1990). Eccagoras [= Euagoras] nigricornis St��l, 1855, described as from ���Minas Geraes��� [now the state of Minas Gerais], Brazil, was recognized as a junior synonym of G. bicolor by C. St��l himself (St��l 1866, 1872). The description (St��l 1855) and photos of the holotype of E. nigricornis are concordant with the idea that these two taxa are identical. The photos of the syntype of E. nigricornis have been made available by the Swedish Royal Natural Museum (Naturhistoriska Riksmuseet, NHRS), and can be freely accessed at http://www 2.nrm.se/en/het_nrm/n/ graptocleptes _ nigricornis.html. Walker (1873 a) based his description of R. coleopteroides on a single female specimen, erroneously thought to be male, without any reference to geographical data, which is also missing from the labels attached to the holotype (Fig. 5). This author, in the next part of his catalogue (Walker 1873 b), cited Myocoris bicolor Burmeister as a valid species, but as a ���desiderata,��� or species that it would be ���desirable to procure for the collection��� as can be inferred by the convention of absence of letters, as explained in the preface, thus denoting that he was unaware that they were conspecific. PLATE 6. Figs 36���39, Graptocleptes bicolor, female, 36���37, head, 36, dorsal view, 37, lateral view, 38, specimen determined as ��� Amaurosphrodus ��� by W. L. Distant deposited in BMNH, head and prothorax lateral view, 39, alive, feeding on a caterpillar. Hiranetis Spinola, 1840 and Graptocleptes St��l, 1866 are two closely related genera (Champion 1898), which together with certain other Harpactorini have been recognized as M��llerian wasp mimics, using various Ichneumonidae and Braconidae as models (Champion 1898, Haviland 1931, Hogue 1993, Maldonado & Lozada 1992). The resemblance resulting from this mimicry has led to misidentification of these two genera, as shown in the present case. In G. bicolor, variable extent of reddish coloration on the pronotum was recorded here (Figs. 2���3, 6, 7, 11���12, 14, 38���39). Reddish coloration in the sternal area of the thorax and trochanters was recorded in the original description (Burmeister 1838), but the coloration of the thoracic sterna in the specimens examined here was variable, going from entirely reddish to brownish-red and to black in the other specimens. The variation of the extent of the reddish to blackish coloration was also noticed in the head (except for the ocellar bases, eyes, and antennae) (Figs. 6, 8���9, 14, 36���38) and thorax, including the scutellum, distal sternites, and connexivum. Significant color variation has been recorded in other Graptocleptes species as well (Champion 1898). St��l (1872) recorded a variation of the coloration of the corium of hemelytra, describing it as either paler (���Var. b. - pallidior ���) or completely blackish (���bb. Corio toto nigricante ���) Males of Graptocleptes can be recognized by their large prominent eyes and the thickened third antennal joint (Champion 1898). Otherwise, regarding G. bicolor, no sexual dimorphism of eyes size was described by St��l (1872) - ��� oculis (���) in utroque sexus aeque prominulis. ��� Although more specimens should be examined in order to confirm these results, the sexual dimorphism of G. bicolor was shown in the specimens examined here to be subtle. Thus, it possibly might go unnoticed in a rapid viewing of specimens. The third antennal segment is slightly thicker in males, whose maximum width of this segment measured 0.18���0.21 mm (min. ��� max.); in females, it was 0.13 ��� 0.15 mm (Tables 1���2, 3). The eyes may seem somewhat larger in males, when comparing separately some specimens of each sex (Figs. 8���9, 36 ��� 37). In fact, the measurements of the transverse width of the right eye in dorsal view showed higher values in males (0.35��� 0.75 mm: min. ��� max.) than in females (0.30���0.45 mm), but the range of 0.35���0.45 mm was found in both sexes, so no differences in the respective specimens could be seen, as observed by St��l (1872). In the specimens from the state of S��o Paulo (Tables 1, 3), the antennal segments I and II were longer in females, with minimum lengths greater than the maximum lengths of the same segments in males; whereas the antennal segments III and IV are longer in males than in females. However, in the other two females from the BMNH, the lengths of the antennal segments I and II are within the range of those of males from S��o Paulo; the other segments are missing, thus not allowing further comparison. On the other hand, in the male from Paraguay, the third antennal segment was shorter than in all other specimens. Therefore, more specimens need to be examined, in order to clarify these possible sexual differences. Lent & Jurberg (1985) studied the male genitalia of specimens of Triatoma dimidiata (Latreille, 1811) (Triatominae) from diverse origins, and pointed out that the same variability noticed in its external color characters and in the relationship between the head and pronotum was demonstrated by structures of the phallus such as the endosoma processes, struts, phallosoma, and vesica. On the other hand, in Triatoma infestans (Klug, 1834), a species with ���stable external characters��� (Lent & Jurberg 1985), the dissection of the male genitalia of specimens from different regions or populations showed only a small variability in struts and endosoma processes (Lent & Jurberg 1985; Pires et al. 1998). Because the dissection of the male genitalia is usually carried out on only one specimen of each species (Lent & Jurberg 1985), the variability of these structures may remain unrecorded. Therefore, in future studies, and particularly in relation to species in which a color or morphological variation is evident, dissection should be performed on more than one specimen of each species, in order to ascertain the possible male genitalia variability, as recorded in the phallic structures of G. bicolor in the present study (Figs. 20���23, 26 ��� 30).

The Canary Archipelago is home to two species of obligately cavernicolous assassin bugs of the genus Collartida Villiers, 1949 (Hemiptera: Heteroptera: Reduviidae: Emesinae: Collartidini). These species are highly adapted for cave life, being blind and wingless. In the present study, we describe a new species of the genus, C. phantasma sp. nov. from the Federica mine in Gran Canaria. C. phantasma sp. nov. differs from the other two Collartida species found in the Canary Archipelago in that the male is fully winged, the female is wingless, and both sexes have well-developed eyes. We provide information regarding the new species’ habitat, its taxonomic affinities, and its ability to fly., We are grateful to Marcos Roca-Cusachs and Marta Goula (University of Barcelona) for providing access to the Ribes collection. We thank Álvaro Monzón for showing us the Federica Mine. We also thank Heriberto López (IPNA-CSIC) for his help during fieldwork and Pedro Oromí (University of La Laguna) for providing information and bibliography regarding troglobiont species of the Canary Archipelago. L.-R. Davranoglou is grateful to the Leverhulme Trust Early Career Fellowship grant (ECF-2021-199) for funding this research. Daniel Suárez was funded by the Ministerio de Ciencia e Innovación through an FPI PhD fellowship (PRE2018-083230). The fieldwork was supported by the project ‘Fauna subterránea del Barranco de los Cernícalos’, funded by the local council of Gran Canaria.
