 Measurements: (10 specimens measured) Average total length: 8.0mm, range: 7.0– 9.1mm, average elytral length: 5.9mm, average elytral width: 2.4mm, average pronotal length: 1.5mm, average pronotal width: 1.6mm, average head width: 1.5mm.   
 Head: Red-brown, cranium vested with short and long yellowish setae, distinctly punctured, interstices smaller one diameter of punctures; posterior part of clypeus red-brown, with long setae especially laterally, punctation large but sparse; ventral part smooth except wrinkles behind the eyes; antennae red-brown, antennomeres gradually decreasing in length from A3 towards A8, A9 to A11 forming a distinct club, A9 separated from A10 and A11, male antennae reaching base of pronotum when laid back; gular sutures parallel, gular process broad.   
 Thorax: Average pronotal length:width ratio 1.0:1; pronotum red-brown, vested with fine long setae, pronotal arch with weak punctation, interstices irregularly, mostly larger than one diameter of punctures, pronotum proper smooth; mesepimeron not smooth in basal half, surface wrinkled, transverse sulcus on anterior part of mesosternum and mesepisternum small, especially weakly developed on mesosternum; prosternum red-brown, smooth; mesosternum red-brown, vested with yellowish setae, surface only slightly wrinkled; metasternum red-brown, punctation very fine and sparse; scutellum circular, red-brown.   
 Elytra: Average length:width ratio 2.5:1; uniformly red-brown, vested with short decumbent and few longer erect setae, punctation small, often weak, striae 1 to 3 mostly without punctation, striae 4 and 5 with some smaller punctures in basal half, striae 6 to 8 with large punctures, striae 9 and 10 again with weaker punctation, interstices between and within striae 6 to 8 smaller than one diameter of punctures, punctation never rasp-like, carination absent   
 Legs: Red-brown, relatively long, tarsal pulvilli yellowish-pale; metatibiae more or less straight, tibial carination absent.   
 Abdomen: Ventrites darker red-brown, punctation distinct and denser at apical margin of each ventrite; lateral margins of male pygidium converging; male ventrite 6 with distinct U-shaped emargination. Male genitalia (Fig. 59): Tegmen short and broad, ventral sclerotization apically dilated, sinus broad; basal half of phallic plates narrow, apical half broad, sinuous, phallic plicae distinctly visible; spicular fork dividing into two branches after one quarter to one fifth of length.   
 Distribution: India, China (Sichuan).   
 Seasonal occurrence: Collected in July.
