Paratypes. 3 ♀. French Guiana • 1♀; Montagne de Kaw, Piste pk 36; 24.VII. 91; P. Grandcolas leg.; low forest (xerophytic); plant at night; Molec 2019 lbr_330; MNHN-EO-ENSIF10889; MNHN. • 2♀; same data as for allotype, MNHN-EO-ENSIF10890-10891; MNHN.
DIAGNOSIS. — This species is separated from the other species of Adenophallusia by the following characters: ocelli absent. Male: FWs covering the entire abdomen, but not supra anal plate; harp crossed by four diagonal veins; median spine of supra anal plate with base not enlarged. Male genitalia: pseudepiphallic sclerite elongated; only inner lobe of LLophi with apex pointed. Female: FWs not covering the last three abdominal tergites. Female genitalia: copulatory papilla cylindrical, posterior half thinner than anterior, unpigmented.
DESCRIPTION
General morphology.
Body. Medium to small size, covered by bristles, general coloration medium brown, legs light brown.
Head. Occiput and vertex covered by light bristles, medium brown. Fastigium as long as wide, pubescent, medium brown (Fig. 14A, C, E). Ocelli absent. Frons with some yellowish bristles on median region, medium to dark brown (Fig. 14E). Eyes longer than wide in lateral view, ommatids dark yellow with some sparse black ones. Antennal scape longer than wide, inner margin with yellowish bristles, medium to light brown, antennomeres medium brown. Gena medium brown in frontal view, light brown in lateral view. Mandibles medium brown, apex darker (Fig. 14E). Epistomal suture dark yellow; clypeus and labrum light to medium brown (Fig. 14E). Maxillary palpi pubescent with light bristles; articles light brown; articles 3-5 almost same-sized; article 5 clavate.
Pronotum. DD slightly longer than wide, covered by bristles; reddish-brown. DD cephalic margin slightly concave, with reddish-brown bristles; caudal margin somewhat convex, with reddish-brown bristles (Fig. 14A, C). LL medium to dark brown; ventro-cephalic angle rounded; ventro-caudal angle gradually ascendant in lateral view (Fig. 14B, D).
Wings. FWs covered by tiny bristles, somewhat translucent, medium brown; veins medium brown.
Legs. Legs I and II with yellowish and brownish bristles. FI and FII light brown. TI and TII light brown. TI with oval inner tympanum. TI with three apical spurs: two ventral, one dorsal, inner. TII with three apical spurs: two ventral, one dorsal, inner. FIII longer than TIII; with yellowish and brownish bristles, light brown; apical region medium brown (Fig. 14B, D). TIII medium brown, with yellowish bristles. TIII subapical spurs 5/4, with two spines between uppermost spurs, one spine between the others; seven spines above the inner spurs, five or six spines above outer subapical spurs. TIII apical spurs 3/3, longer on inner side; inner apical spurs: dorsal (iad) and median (iam) with same length, ventral the smallest (iav) (iad=iam>iav); outer apical spurs: median longest (oam), dorsal slightly shorter (oad), ventral almost same size of dorsal (oav) (oam>oad>oav). TIII apical and subapical spurs and spines light brown with apex medium brown (Fig.14 A-D). Basitarsus dorsal spines 3/3, apical spine the longest; inner and outer apical spur same size, shorter than basitarsus. Basitarsus medium brown.
Abdomen. Tergites slightly pubescent, medium brown.
Male
Morphology. FWs covering abdomen but not supra anal plate; PCu vein curved on anterior region, bearing a stridulatory file. Harp crossed by four diagonal veins, connected to CuPa, third and fourth connected apically; CuPb short; mirror divided on the middle by a curved vein (Fig. 14A). Lateral field with c. 13 parallel veins, perpendicular to dorsal field in lateral view. Supra anal plate bearing a median spine, posterior margin rounded; dark brown, median region black (Fig. 14F, G). Subgenital plate posterior margin straight, strongly pubescent; medium brown, bristles yellow (Fig. 14H).
Male genitalia (Figs 15 A-C, 16). Phallic complex not glandular (different from type species). Pseudepiphallus: pseudepiphallic sclerite general shape triangular in dorsal and ventral views, longer than in Adenophallusia legendrei n. sp., slightly upcurved in lateral view, anterior margin concave in dorsal view. MLophi absent. LLophi slightly curved inwards in dorsal view; outer lobe longer than inner lobe; apex of outer lobe rounded, apex of inner lobe pointed. PsP almost same size as LLophi, not surpassing their tip; with two lobes, outer and inner; tips of outer lobe rounded, tip of inner lobe rounded; outer lobe longer than inner lobe. R elongated, shorter than pseudepiphallic sclerite, flattened laterally, anterior region curved inwards. Ectophallic invagination: EctAp almost same size as LLophi, almost straight in dorsal and ventral views; surpassing the anterior margin of pseudepiphallic sclerite. Arc not complete, flattened dorso-ventrally, median apex slightly curved posteriorly in dorsal and ventral views; ventral projections of ectophallic invagination short, as long as half Arc. EctF membranous, posterior margin rounded. Endophallus: EndSc weakly sclerotized, longer than wide, oval in dorsal and ventral views, anterior and posterior margins rounded.
Female
Morphology. Body larger than male, general coloration similar to male (Fig. 14C, D). FWs not covering the last three abdominal tergites; bearing six longitudinal veins. Supra anal plate anterior margin rounded, medium brown, laterals dark brown (Fig. 14I). Subgenital plate wider than long, posterior margin concave medially; light brown, covered by yellowish bristles (Fig. 14J). Ovipositor upcurved, medium to dark brown; apex tip pointed (Fig. 14I, J).
Female genitalia (Fig. 15 D-E). Copulatory papilla longer than wide, cylindrical, almost straight in lateral view, without ventral aperture; posterior half thinner than anterior, unpigmented; posterior margin straight, anterior margin convex in dorsal view.
