Discussion.
The female is included here with some doubt as the locality is unknown and also the locality of the
holotype
is rather imprecise. Thus one cannot be certain that they really represent the same species. Also the female from
Sikkim
mentioned by
Karny (1929a)
may represent a different species.
Description.
Medium sized species (
Fig. 60C
). Head: Face broad avoid, strongly rugose; fastigium verticis more than twice as wide as scapus, bordered laterally in frontal view by curved carinae; ocelli indistinct (in female lateral ocelli contrasting yellow); fastigium frontis separated from fastigium verticis by a fine curved suture; subocular furrows little distinct (
Fig. 61L
).
Wings absent (
Figs. 60C, E
).
Legs: Fore coxa with a spine at fore margin; fore and mid femora unarmed; fore and mid tibiae with four pairs of not very long spines and one pair of apical spurs on ventral margins; hind tibia on ventral margins without pre-apical spine.

male (H–J) and female (K–L).—Male abdominal apex in apical (A, J), ventral (E, I), lateral (F) and dorsal view (H), pro- and mesonotum with reduced tegmen in dorsal view (B), pro-, meso- and metanotum in lateral view (G), ventral base of female ovipositor and recurved subgenital plate (C), subgenital plate in anterior view (D), female subgenital plate and tip of seventh abdominal sternite (K), ovipositor with tip of abdomen in lateral view (L). Long scales 5 mm, short scales 1 mm.
Coloration. General color brown, thorax with few black spots; head mainly black; spines on hind femur and hind tibiae black. Face black; lower parts of clypeus and labrum of lighter color (in male also lateral carinae of fastigium).
Male. Eighth abdominal tergite brown; prolonged and towards end globular. Ninth abdominal tergite oriented ventrally compared to eighth tergite; with down-curved and approaching lateral margins; recurved apical margin in middle with a pair of small black spines. Subgenital plate wider than long with medial furrow; lateral margins concave, apical margin convex; small styli inserted at lateral angles (
Fig. 61M
).
Female. Seventh abdominal sternite conically narrowing backward followed by an oval expansion at end, the latter with a pit; lateral areas membranous. Subgenital plate semi-oval with membranous base (
Fig. 61N
). Ovipositor elongate and little curved; tip more strongly upcurved (
Fig. 60E
).
