Caraphia ebenina Holzschuh, 1989: 361 , figs. 1, 10 (Type locality: Tam Dao, N. Vietnam); Chou & N. Ohbayashi, 2008: 142, fig. 4.

Diagnosis. Male: BL= 13.2–14.5 mm; EW= 4.1–4.5 mm. Body mostly black. Antennae long, 1.46 times as long as body length with apical three and a half segments exceed the apex of elytra; 3rd longer than 4th; relative lengths of segments from base to apex: 67: 13: 75: 68: 88: 78: 76: 69: 67: 63: 73. Pronotum slightly longer than wide, constricted at apical fourth, then expanded laterally near middle; disk strongly convex, densely punctured and reticulately sculptured, provided with a pair of protuberant at apical fourth and a median callus at basal third in front of basal depression. Elytra densely and rather irregularly foveate in rows; scales whitish, short and barely curved, 1.0 times as long as the diameter of each fovea, alternating on rows of foveae.

Genitalia ( Fig. 117 ) with paramere of tegmen 3.45 times as long as basal width, slightly emarginate on basal half of outside, then narrowed apically, 0.24 times as long as tegmen. Median lobe with dorsal plate not reaching the apex of ventral plate; basal struts one-third length of median lobe. Endophallus ( Fig. 131 ) with MPH gently curved dorsally, with dense hair-like fine spicules and a pair of sclerites near base; APH narrowed, with a rod-like sclerite.

Female: BL= 15.3 mm; EW= 4.7 mm. Very similar to male in body color, foveae and scales. Relative lengths of segments from base to apex: 71: 13: 82: 73: 90: 83: 81: 74: 70: 69: 80.

Distribution. North Vietnam; China (Guangxi).

Remarks. This species is characterized by its uniquely black body and the very short, white scales of the elytra. It is recorded from China for the first time.
