Gular sutures subparallel, widely separated. Eyes very small, oval, coarsely faceted, composed of six or 36 facets (as based on the studied specimens). Antennal sockets concealed by sides of frons, not visible from above; antennal grooves absent. Antenna comparatively short (Figs 1e, 5c), almost reaching base of pronotum, composed of ten antennomeres with club formed by terminal antennomere which is large, inflated, subtriangular, truncate apically. Frontoclypeal suture weakly arcuate (Fig. 6a). Clypeus transverse, flat, convergent anteriorly. Labrum (Fig. 1a) subquadrate, with rounded anterolateral corners, truncate apically, with submembranous apex, punctate, covered with sparse, long setae; tormae with mesal arms recurved posteriorly; labral rods absent. Mandible (Fig. 1c) with two apical teeth, and with four smaller subapical teeth getting subsequently smaller posteriorly; prostheca covered with digitiform setae on anterior third getting thinner and shorter toward posterior 2/3; mola large, sclerotized; submola small, membranous. Maxilla (Fig. 1b) with palpomere 1 and 3 very short; palpomere 2 large and swollen, almost twice as long as palpomere 3; terminal palpomere approx. 1.5 times as long as 2 and 3 palpomeres combined, narrow, tapering, apex obliquely truncate to weakly rounded; galea moderately broad, twice as broad as lacinia, with long, broad, apical spine-like setae; lacinia elongate, with spine-like setae on apical half. Labium (Fig. 1d) with palpomere 1 very small; palpomere 2 largest, oval, inflated; terminal palpomere transverse, truncate at apex. Mentum subquadrate, with produced anterior angles; finely punctate, glabrous. Prementum subquadrate, sclerotized, with apically expanded membranous ligula.

slightly projected, rounded angles; posterior angles almost right-angled. Pronotal disc weakly convex. Pronotal base with an impression composed of two longitudinal sharply defined sulci, slightly convergent anteriorly, almost reaching apical fourth, and a pair of deep transverse linear depressions/sulci. Anterior transverse sulcus flanked by one small deep fovea on each side; area between transverse sulci convex; basal sulcus not reaching lateral sulci, with or without large foveate punctures. Prosternal process (Figs 5f, 6e) broad, approx. as wide as coxal diameter, with raised margins; extending posteriorly beyond front coxae. Procoxa circular in outline, its cavity externally open behind, internally closed; trochantin concealed (Figs 5f, 6e).

Mesoventrite (Fig. 1f) carinate at middle; intercoxal process moderately elongate, rather broadly separates mesocoxae (slightly narrower or slightly wider than coxal diameter) reaching half of their length. Mesoventrite (Figs 1f, 5f, 6e) fused with mesanepisternum (trace of suture visible). Mesocoxa weakly oval in outline, its cavity narrowly closed outwardly by sterna; trochantin concealed. Meso-metaventral junction of straight-line type, without internal knobs. Elytron (Figs 4a, c, 6d) elongate, convex, irregularly and moderately finely punctate, with a hooked tooth on anterolateral corner, epipleuron narrow, incomplete at apex. Sutural stria sharply defined, complete, widest at mid length, then weakly converging towards elytral apex. Metaventrite (Fig. 1f) transverse, twice as long as mesoventrite, weakly convex; with postcoxal longitudinal ridges nearly reaching anterior 2/5; anterior margin rather thick; discrimen very short. Metanotum (Fig. 1h) sclerotized. Metacoxae transversely oval, widely separated. Metendosternite with very short stalk and moderately widely separated anterior tendons. Hind wings absent or present and well developed, longer than elytra, with anal, medial and radial fields elongate and narrow, apical field enlarged; margins surrounded with long hairs.</paragraph>
