DIAGNOSIS. — This species is separated from the other species of Adenophallusia by the following characters: metanotum with two median projections rounded in dorsal view; first abdominal tergite with a depression resembling an inverted heart in dorsal view. Male: FWs covering the entire abdomen; stridulatory with c. 56 stridulatory teeth; harp crossed by three diagonal veins; median spine of supra anal plate with base enlarged. Male genitalia: both lobes of LLophi with apex of pointed; EndSc oval in dorsal and ventral views, anterior and posterior margins rounded. Female: FWs covering abdomen but not supra anal plate; posterior tip of ovipositor pointed. Female genitalia: posterior margin of copulatory papilla with a median rounded projection in dorsal view.
DESCRIPTION
General morphology.
Body. Medium to small size, covered by bristles, general coloration medium brown, legs light brown.
Head. Occiput and vertex covered by yellowish bristles, medium brown. Fastigium as long as wide, pubescent, dark brown (Fig. 11A, E). Lateral ocelli small, rounded; median ocellus absent. Frons without bristles, dark brown (Fig. 11E). Eyes longer than wide in lateral view, dorsal ommatids whitish, others black (Fig. 11B, E). Antennal scape longer than wide, inner margin with yellowish bristles, light brown, marbled dark brown; antennomeres medium brown. Gena medium brown in frontal view, light brown in lateral view. Mandibles dorsal half dark brown, ventral half light brown, apex darker (Fig. 11E). Epistomal suture medium brown; clypeus light to medium brown, dark brown punctuated; labrum light brown, dark brown punctuated laterally (Fig. 11E). Maxillary palpi slightly pubescent with yellowish bristles; articles light brown, article 5 darker; articles 3-5 almost same-sized; article 5 clavate.
Pronotum. DD slightly wider than long, covered by bristles light yellow; medium brown. DD cephalic margin slightly concave, with reddish-brown bristles; caudal margin somewhat convex, with reddish-brown bristles (Fig. 11 A, C). LL medium to dark brown; ventro-cephalic angle rounded; ventro-caudal angle gradually ascendant in lateral view (Fig. 11B, D).
Wings. FWs not covered by bristles, light to medium brown, somewhat translucent; veins light brown (Fig. 11A, C).
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; no outer 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 bristles, medium brown; apical region dark brown (Fig. 11D). TIII medium to dark brown, with yellowish bristles. TIII subapical spurs 5/4, with two spines between most proximal spurs, one spine between the other spurs; seven spines above inner spurs, five or six spines above outer subapical spur. 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 dark brown with apex medium brown (Fig. 11A, C). Basitarsus dorsal spines 3/3, apical spine the longest; inner and outer apical spur same-sized, shorter than basitarsus. Basitarsus dark brown.
