Caraphia laosica Gressitt & Rondon, 1970: 30 , fig. 7d (Type locality: "Khongxedon, Wapikhamthong District, Laos " (current Saravane Prov., Laos)); Hayashi & Villiers, 1985: 24, 26; Chou & N. Ohbayashi, 2008: 141.

Diagnosis. Male: BL= 11.9–12.2 mm; EW= 3.1 mm. Body mostly blackish brown. Antennae brown, exceeding elytral apex at the middle of 9th segment; scape 3.2 times as long as wide; relative lengths of segments from base to apex: 63: 14: 51: 50: 86: 86: 74: 74: 74: 72: 80. Pronotum 1.2 times as long as basal width, basal half nearly parallel-sided then slightly convergent apically; sub-recumbent scales becoming short and thin besides median area and the scales showing obscure three longitudinal vittae. Elytra densely and rather regularly foveate in rows; scales pale yellow, suberect and barely curved, truncate at the apex, 1.5 times as long as the diameter of each fovea, alternating on rows of foveae.

Genitalia ( Fig. 118 ) with paramere of tegmen gently narrowed apically, 4.35 times as long as basal width, 0.21 times as long as tegmen. Median lobe with dorsal plate same length as ventral plate; basal struts distinctly shorter than one-third of median lobe. Endophallus ( Fig. 132 ) with MPH turned up dorsally at the middle, with dense hairlike fine spicules and a pair of sclerites near base; APH narrowed, with a rod-like sclerite.

Female: Unknown.

Type material examined. Holotype: ♂, Khong Sedone , Wapikhamthong Prov., Laos, 18-IV-1965 ( J. A. Rondon Collection, BPBM) . Paratype: 1♂, same locality, 16-V-1965 (J. A. Rondon Collection, BPBM).

Distribution. Laos.

Remarks. Only the two type specimens are known. This species can be distinguished from the other congeners by its dark brown body color, pronotum with vague longitudinal vittae of scales, and the structure of tegmen of male genitalia. The record of this species from Hainan, China by Hua et al. (1993) was a misidentification of C. taiwana .
