D e s c r i p t i o n o f m a l e h o l o t y p e. Body reddish brown, incrustation grayish brown. Eyes reddish. Antenna and legs covered with short curving hair.

H e a d: Slightly longer than wide across eyes (0.85/0.80); covered with stiff erect hairs; clypeus and genae short, not produced beyond apex of labial atrium; antenniferous tubercles short, dilated, apices blunt; eyes small, semiglobose and laterally protruding; postocular lobes without tubercles, strongly constricted posteriorly; vertex with X-shaped sulcus; antennae 3.2 times as long as width of head across eyes, length of antennal segments I to IV: 0.74/0.56/1.03/0.32; labial atrium closed, with a slit-like opening, rostrum short, rostral groove deep, closed posteriorly.

P r o n o t u m: 1.48 times as wide as long (1.40/0.77), attenuated anteriorly; collar thick, as wide as first antennal segment; separated from pronotum by a transverse furrow; anterolateral angles of pronotum not protruding, reaching to collar; anterior part of disc with deep median longitudinal impression, flanked by 2(1+1) large humps with irregular carinae and conical tubercles, covered by stiff erect hairs; posterior part of disc separated from anterior part by a transverse furrow, surface smooth and sloped to posterior margin, separated from mesonotum by a convex suture.

M e s o n o t u m: Wider than pronotum (1.65/1.40), with distinct scutellum, laterally deeply depressed and bulbous anterolateral wingpads.

M e t a n o t u m: Wider than mesonotum (1.89/1.65), fused to mtg I and II into an elongate plate with longitudinal ridge and 4 (2+2) oval glabrous callosities; the fusion line is marked by a thin bisinuate carina; deltg I + II fused, produced forward to mesonotal wingpads.

A b d o m e n: Deltg III-VII distinctly raised laterally, rather bare on inner half, with stiff erect pilosity on outer half; posterolateral angles of deltg VI to VII progressively protruding, deltg VII with triangular lobes; tergal plate consisting of mtg III to VI, subquadrangular with a longitudinal median ridge and lateral pattern of oval callosities; scent glands distinct; laterad of median ridge with a usual pattern of large and small callous spots; paratergites VIII clavate, produced beyond cordate pygophore,

V e n t r a l s i d e: Sterna III to VI raised along posterior border, depressed along anterior border, and with T-shaped, smooth ridge medially; flanked by 2 (1+1) large, transversely ovate deep depressions, with transversal broad carina, these bearing 2 (1+1) round callous spots; more laterad 4 (2+2) smaller round callous spots; spiracles II+III lateral, IV sublateral and barely visible from above, V-VII ventral, VIII terminal.

L e g s: Long, slender; fore tibiae with preapical spine-like combs.

F e m a l e: Morphological features basically as of male; head about as long as wide across eyes; mtg VII slightly elevated medially, depressed posteriorly, paratergites VIII dentiform, reaching to basal 1/3 of tergum IX.
