Length. 1.9–2.5 mm (without rostrum)
Head & Rostrum. Eyes clearly visible from above, round towards forehead when viewed laterally and from the front, but tapering to underside of rostrum; forehead broad, almost as broad as base of rostrum; flattened rostrum of male 3.1× as long as wide between antennal insertions, densely covered with light-coloured scales in upper part, finely punctured in apical half; rostrum of females 4.0× as long as wide, scaly only immediately in front of base, otherwise shinier and much more finely punctured towards apex; when viewed laterally rostrum only slightly curved immediately in front of base, otherwise straight to apex in both sexes; antennae short, club-shaped scape not as long as width of dorsum of rostrum between antennal insertions; antennomere 1 of funicle conical, approx. 2× as long as at widest point, antennomere 2 very narrow, only slightly longer than wide, antennomeres widening from 3rd to 7th segment, slightly shorter than wide; club short-oval.
Pronotum. 1.1× as wide as long, widest at or immediately behind middle, there laterally strongly convex, towards basal and anterior margins—there with a slight depression-narrowed in a straight line; fine punctation covered with large round, light, tightly fitting scales, only occasionally with dark brown, erect bristles condensed into small tufts on disc.
Elytra. Inversely ovate, but at most 1.1 x as long as wide; widest at about end of basal two-fifths; striae with fine, elongate punctures clearly narrower than slightly arched intervals, which are several times wider; intervals also predominantly covered with round, light and dark brown scales, which often show a banded pattern, albeit irregularly limited; erect, beige and brown, somewhat flattened scales, which are placed at large intervals in a single row on interstriae are at most 1.5 times as long as wide.
Legs. Legs, but especially femora, long; fore femora reaching to base of rostrum, hind femora reaching apex of elytra; covered with spindle-shaped, white and light brown scales, which do not completely cover underlying cuticle; scales protruding slightly on th outer faces of tibiae.
Underside. Venter with a deep rostrum channel whose mesosternal receptaculum is semicircular and ends in front of mid-coxae; abdomen with five segments with light-coloured, widely spaced scales, each scale 3×–3.5× as long as wide; 2 nd ventrite strongly punctate, sloping obliquely to narrow 3rd and 4th ventrites, only slightly longer than 3rd and 4th combined.
Aedeagus. Median lobe of aedeagus flatly rounded (if the aedeagus aligned exactly ventrally), but ovally rounded when only the tip rests flat; endophallus consisting of two narrow, closely spaced bars, each with an inwardly inclined long, spine-like tip ( Fig 2 View FIGURE 2 ).
