Description
Description. Length.2.3–3.2 mm (without rostrum). Head & Rostrum. Eyes large, rounded. Rostrum of males red brown; length-width ratio of 4.0 between insertion of antennae; closely covered with white and beige scales in front of base, finely punctate towards apex; rostrum of females clearly longer; length-width ratio of 5.5 between insertion of antennae, more shiny, more finely punctate. Last five antennal segments as long as broad, trapezoidal, clearly separated from club; first two segments elongate. Pronotum. Only slightly broader than long; widest in middle or immediately behind middle; regularly, strongly rounded laterally towards fore-margin and towards base; with slight depression at sides directly behind fore-margin. In lateral view, contour-lines of pronotum and of elytra form a uniform bend, not clearly separated; in front of fore-margin flattened, towards base slightly more curved. In dorsal view without keels or humps on levelled disc of pronotum. Integument of brown and beige, circular non-overlapping scales, cuticle visible between scales. Small pits of the pronotum are fine, closely separated. Pronotum with very long, slender bristles (dorsal view). Elytra. Length-width ratio of 1.20 (holotype); widest at end of first fourth, slightly obovate; behind middle acuminate-ovally, rounded towards apex. In lateral view the contour-line of elytra flat behind base, forming arc towards apex at declivity. Integument not rich in contrast of (dark)brown and beige, circular non-overlapping scales, cuticle visible between scales. Striae much smaller than intervals, with elongate, closely packed shallow punctures. Clubbed bristles on sutural stripe and intervals at most 2 to 2.5 times as long as wide, their separation ranging from two to three times length of a bristle. Legs. Short; margin of front femur reaching fore-margin of eyes, hind femora ending in front of elytral apex. Covered with predominantly beige, not overlapping, elongate scales and very long, erected bristles, male with split apical spine on middle tibia. Venter. Abdomen with 2 nd sternite clearly shorter than 1 st sternite and slightly longer than sternite 3 and 4 together.
Female genitalia. Spermatheca, ovipositor, spiculum ventrale, fig. 6 Aedeagus. Apex of the aedeagus elongate, endophallus with two lines, fig. 5
