and

hue

Head: juga narrow, margins parallel, leaving antenniferous tubercles uncovered, fitted with a tooth at the proximal margin in front of each eye, rounded at the apex, clypeus much shorter and completely enclosed in juga: second and third segments of antennae subequal in length, 4m segment longer than the 2hh by 25 to 50 %; pilosity dense, length of the hairs about one fourth of segmental diameter; rostrum short, slightly surpassing anterior coxae.

Pronotum: humeral processes extending beyond lateral margins of abdomen, their margins sub-parallel, slightly curved anteriorly, and obliquely truncated, anterior angle blunter than posterior, extending anteriorly beyond anterior margin of pronotum, reaching to about middle of eye; width of pronotum, including humeral processes, slightly more than 70 % of total length of habitus in males, slightly less in females. Calli smooth, moderately marked; lateral margins thinly wrinkled; punctation coarse and irregular on disk; stemal process long, with apex blunt, reaching fore margin of anterior coxae; distal apex of femora fitted with spines either side of tibiae insertion; first segment of tarsi inflated, with a brush of adhesive hairs on the ventral surface, segments two and three cylindroconical, second segment very short.

Scutellum: punctation similar to pronotum, triangular with apex lanceolate.

Hemelytron: punctation fine and regular; membrane with four basal cells, veins strong, parallel.

Abdomen. Male: posterior margin of pygophore, in normal position, only slightly surpassing th the posterior margin of the seventh segment; female: 7 laterotergites extending posteriorly more or less surpassing abdominal apex, 8m laterotergites weakly concave; venter finely granulated.

Genitalia (cf. fig 4—7). 3: pygophore (fig 4) widening posteriorly, posterior margin slightly concave; opening with a tooth on each side, slightly curved medially, located just anterior to sensorial lobe of paramere. Pararnere (fig. 5) triangularly blade-shaped, evenly curved medially, sensorial lobe relatively small, with very long setae; phallosoma (fig 6) fitted with two sclerotized plates, dorsally protruding; conjunctiva fitted with two pairs of processes, as is the rule in this genus, one sclerotized in antero-ventral position, stylet bifurcated and nearly symetrical (6 a), and the other membranous in postero-dorsal position; vesica very long, ejaculatory reservoir strongly curved at base, S-shaped in middle, and strongly tapering at apex. Q: (fig 7); external genitalia as in the other species of genus (see MAGNIEN et al., 2008). Spermatheca (fig. 13): apical receptacle ovoid connected to the intermediate part (pumping region) by a long distinctly tubular neck curved at right angle; intermediate part with proximal flange very reduced, distal normal; spermathecal duct bipartite: posterior part wide and folded, lanceolate, anterior part long and thin, little more than half as long as posterior part.

Measurements, (mean(min-max)): male: length: 18,9 mm (17,6-20,9) - width including humeral processes: 12,5 mm (11,3-14,9) - maximum width of abdomen: 11,2 mm (10,4- 12,5) - length of antennae: 8,53 mm (8,28-9,04) - ratio length of the 4th antenna segment to the length of the 3rd: 1,34 (1,26- 1,48). Female: length: 21,6 mm (20,3-23,7) - width including humeral processes: 12,5 mm (11,3- 14,9) - maximum width of abdomen: 12,7 mm (11,9- 13,8) - length of antennae: 8,58 mm (8,04-9,15) - ratio length of 4th antenna segment to length of 3rd: 1,29 (1,23¬ 1,36)
