Redescription

Size: 2.2-3.6 mm. Body color auburn. Head hidden in pronotum, eyes oval, flat and small, comprising six to eight ommatidia, eyes lateral of rostral base, below middle of rostral diameter (Fig. 1G). Rostrum constricted at base, about 3.5 times longer than wide at level of insertion of antennae (Fig. 1A), parallel sided along basal 2/ 3 in dorsal view, widened from antennal insertion to tip, buckled downwards at basal constriction in lateral view (Fig. 1D), ventral side straight to tip, dorsal side weakly bowed. Dorsum of rostrum tricarinate in basal half, middle carina diverging behind antennal insertion, and converging before, thus opening a spindle-shaped groove. Sides of rostrum coarsely punctuate, tip of rostrum glabrous and with fine punctuation. Vestiture consisting of yellowish recumbent bristles, these standing in rows on dorsum of rostrum (Fig. 1A), pointing towards spindle-shaped groove along carinae, longer recumbent bristles beard-like below lower edge of antennal scrobes (Figs 1B, G). Antennal insertion behind last fourth of rostral length, scrobes lateral, straight pointing to lower margin of eye (Fig. 1D), reaching ventral side of rostrum (Fig. 1B).

Antennae with scape a bit longer than one third of rostrum, parallel sided from base to last third, from there on culled. Antennal funiculus with 7 segments, first one twice as long as wide, second 1.5 longer than wide, following ones wider than long, steady broadened towards club (Fig. 1I). Club with jar-shaped first segment (Fig. 1I), as long as last four funicular segments together, following two hardly visible ones short and flat, club densely covered with whitish hairs.

Pronotum L/W: 1.0-1.1times about as long as wide, roundish, strongly constricted behind fore margin, only weakly at hind margin, with V-shaped impression on upper side, and a longitudinal carina, which ends before hind margin in a deep impression (Fig. 1F). Pronotum densely and coarsely punctuate, vestiture consisting of yellowish recumbent bristles. Scutellum hardly visible, punctiform. Ventral side at fore margin with a faint and shallow rostral notch or channel. Procoxae close to each other, separated by a thin interspace (Fig. 1C). Mesocoxae separated by half their diameter, mesosternal process trapezoid (Fig. 1E), coarsely punctuate; Metacoxae separated from mesocoxae by hardly their diameter, and twice their diameter between themselves (Fig. 1J); length of metasternum hardly as long as diameter of mesocoxae or as long as two of the coarse punctures in line; in middle on first ventrite with roundish-oval groove due to confluent 2 or 3 huge punctures (Fig. 1J).

Elytra L/W: 1.4-1.5, elongate, parallel sided, widest in middle, no humeral calli, apterous (Figs 2 D-F). 10 striae very coarsely and regularly punctuate, counting 10-12 punctures from elytral base to declivity, intervals narrow, elevated in shape of prominent ridges, uneven ones higher elevated and somewhat wider. Vestiture with same bristles as pronotum and rostrum, bristles in one row on even intervals and 2-3 irregular rows on uneven ones.

Ventral side abdomen (Fig. 1J): Five glabrous ventrites, first and second ones fused but separated by a suture fainted in middle; first and second ventrites coarsely punctuate with sparse yellowish appressed hairs, directed backwards; following two similarly narrow, with one row of bowed hairs, last ventrite finely punctuate with more dense standing appressed yellowish hairs.

Legs: unarmed, strong, set with yellowish appressed hairs; tibiae with a fringe of orange stiff spines at apex; inner angle of tibiae with strong uncus directing inwards (Fig. 1H), tibiae with three subsequent strong tarsomeres, third one bilobed, fourth minute, narrow, claw segment narrow, longer than second and third combined, claws free.

Genitals, male: penis tube shaped, dorso-ventrally flattened, bowed in lateral view, apex blunt in dorsoventral view, almost rectangular or conical with rounded sides, in lateral view apex pointed, apex at dorsal side, just before weakly sclerotized window, with fringe of several straight appressed setae (Figs 3 I-L).

Female: ventrite VIII (or spiculum ventrale) with rhomboidal plate, feebly sclerotized in middle (Fig. 4C), apodeme 1.5 the length of plate with anchor-shaped apex. Spermatheca c-shaped with broad and rounded cornu, base bottle shaped with hardly noticeable ramus and nodulus (Fig. 4F). Gonocoxite of ovipositor triangular, weakly sclerotized, styli pointed (Fig. 4H). Bursal atrium remarkably strong sclerotized (Figs 4 J-K), cab-shaped with small bubble at apex.
