Caraphia thailandica Hayashi & Villiers, 1987: 2 (Type locality: Doi Pui, Chiang Mai, N. Thailand); Chou & N. Ohbayashi, 2008: 141; Weigel et al., 2013: 66, pl. 2, fig. d.

Diagnosis. Male: BL= 8.2–9.4 mm; EW=2.0– 2.3 mm. Body reddish to dark brown. Antennae with apical three segments exceeding elytral apex; scape 3.7 times as long as wide; relative lengths of segments from base to apex: 76: 13: 60: 63: 100: 92: 84: 81: 81: 79: 87. Pronotum 1.2 times as long as basal width, nearly straightly convergent from base to apex; sub-recumbent scales becoming slightly denser laterally. Elytra elongate, ca 2.7 times as long as basal width, densely and rather regularly foveate in rows; scales pale yellow, suberect and barely curved, 1.3 times as long as the diameter of foveae, alternating on rows of foveae.

Genitalia ( Fig. 119 ) with paramere of tegmen elongate, 5.00 times as long as basal width, gently narrowed apically, 0.30 times as long as tegmen. Median lobe with dorsal plate distinctly shorter than ventral plate; basal struts short, less than one third of median lobe. Endophallus ( Fig. 133 ) similar in shape with C. laosica but MPH curved in S-shape together with APH and rod-like sclerite.

Female: BL= 8.2–9.5 mm; EW= 4.1–4.8 mm. Very similar in general features with male. Antennae slightly shorter than male, relative lengths of segments from base to apex: 68: 13: 56: 59: 94: 87: 83: 81: 82: 81: 85.

VII.27, leg. Jian-Guo Long ( SYSU, En-366116); 1♂, Dongylinchang, alt. 750 m, Bawangling, Changjiang, Hainan, 5–7-VI-2008, Yi-Bin Ba and Jun-Tong Lang leg. (HBU= Hebei University, China).

Distribution. Thailand, China (Yunnan, Hainan).

Remarks. This species has a close relationship with C. borneana and C. huai sp. nov., but is distinguishable by the very narrow interocular distance, and long parameres of tegmen. The specimens from China are rather variable in antennal length and the length of the parameres of tegmen when compared with the specimens from Thailand, but thought to be C. thailandica based on the other features.
