Aacanthocnema torulosae

Description. Adult (Figs 51 – 57). Colour: Male: general colour pale cream to ochraceous with brown to dark brown markings. Vertex ochraceous; genal processes pale; antennal segments 1 – 2 pale brown; segment 3 pale, darker apically; segments 4 – 10 brown to dark brown; pronotum mesoscutum, mesopraescutum and mesoscutum with pale orange infuscation (sometimes with a very pale median longitudinal stripe); mesoscutellum pale ochraceous; wings clear; legs pale with dorsal brown infuscation; tarsi pale brown; abdominal tergites light brown to brown; proctiger subgenital plate, and aedeagus pale; parameres pale with brown apices. Female: As for male, except pale longitudinal stripe on mesoscutum more prominent, abdominal tergites brown to dark brown, distinctly darker medially especially on distal segments; proctiger with a pair of dark brown markings lateral to circum-anal pore ring; subgenital plate with pale brown infuscation towards apex. Structure: measurements and ratios as in Tables 1 – 5. Antennae short, 1.30 – 1.71 times width of head; genal processes broad, conical, rounded with blunt, slightly divergent apices; anterior margin of vertex rounded from dorsal aspect, delineated from genal processes by prominent ridge; vertex without obvious fovea and weak medial suture; pronotum with weak median node; thorax weakly arched; head about as wide as pronotum, narrower than mesoscutum; fore wings short with apex broadly rounded; veins R + M + Cu trifurcating very little shorter than mid length of wing, Rs very short, terminating on costa well short of apex of wing; m 1 cell short, broadly triangular, m 1 cell value 0.86 – 1.16; cu 1 cell short triangular, cu 1 cell value 0.95 – 1.32; radular areas elongate, triangular, at margin of wing in cells m 2 and cu 1; male terminalia as in Figs 63 – 64; proctiger simple, without lateral expansion; apical segment of aedeagus short; parameres expanded basally, with strongly inwardly-curved blade-like apices. Female terminalia as in Fig 65; proctiger short, broadly rounded, dorso-posterior margin rounded from lateral aspect; subgenital plate very short, broadly rounded, apex truncate from lateral aspect. Nymph (Figs 58 – 59): Measurements and ratios as in Tables 6 – 7. Body dark brown to black with light brown markings. Eyes dark brown; head with anterior margin light brown; thorax with medial brown marking anteriorly, meso-and metathoracic depressions dark brown to black with a light brown medial marking between them; caudal plate with a broad light brown medial longitudinal stripe. Body elongate-ovate; anterior margin of head weakly pointed medially; mesothorax and caudal plate very prominently arched; metathoracic depressions very deep; dorsum of body without medial longitudinal ridge; caudal plate broad with hind margin broadly rounded.
