(Figs. 1–13)  
 Description. Total length ¼ 3.9 mm. Body length/elytral width ¼ 1.5. Body elongate and highly convex (Figs. 1–2); pronotal depth ¼ 1.08 mm, depth at center of elytra ¼ 1.00. Color of body redbrown. Surfaces glabrous and covered with punctures and microsculpture of points and meshes, microsculpture more pronounced on ventral surfaces, becoming somewhat lineate on flattened leg segments.Head with punctures separated by 1 diameter.Eye finely faceted, greatest length 14 facets, greatest width 24 facets. Pronotum about 0.7 times as long as wide (PL/PW ¼ 0.72); punctures separated by 0.5–1.5 diameters, stronger at center; weak apunctate line present along midline. Hypomeron with anteromesal surface glabrous. Scutellum well developed; apically angulate. Elytra about 1.4 times as long as wide (EL/EW ¼ 1.44) and 2 times as long as pronotum (EL/PL ¼ 2.0); punctures separated by 1.0–1.5 diameters, weakly impressed and forming weak lines at apex; apices slightly rounded with inside corners angulate; epipleuron visible in lateral view, greatest width subequal to width of mesocoxa. Pygidium with punctation similar to that on head. Ovipositor with the apex of gonocoxite bearing 4 setae; apex of gonostyli bearing 4–5 setae (Fig. 11).   
 Comments. The holotype specimen was largely intact, but was missing the mesotibiae and tarsi. After drawings of the body were completed, the specimen was dissected so that the mouthparts and genitalia could be examined and drawn. Prior to dissection it was soaked in weak KOH that turned the cuticle darker than the original color. The head (and its appendages), right hind wing, and genitalia are preserved in glycerin and placed in a genitalia vial while the remainder of the specimen is pinned (two legs are pinned separately below the specimen). The paratype is complete and intact except for the pygidium and genitalia, which are in a glycerin vial.   
The hindgut was mainly empty, apart from about 20 dark pigmented fungal spores lacking external features, in particular an apiculus, germ pore, or germ slit, which identifies them as an undetermined Ascomycete.
