Caraphia depressa Holzschuh, 2003: 147 , fig. 1 (Type locality: Pahang, Cameron Highlands, Malaysia); Chou & N. Ohbayashi, 2008: 142.

Diagnosis. Male: BL= 11.3–11.5 mm. Body dark reddish brown, rather stout; antennae brown; scales of elytra orange-yellow, suberect and barely curved, 2.0 times as long as the diameter of each fovea. Antennae with apical two segments exceeding the elytral apex; scape short and thick, 1.92 times as long as wide, relative lengths of segments from base to apex: 54: 15: 61: 61: 89: 86: 84: 81: 81: 77: 88.

Pronotum same as long as wide, provided with lateral triangular tubercles, deeply constricted near apical third and moderately so at basal fourth; disk between constriction with a pair of protuberant.

Elytra with disk swollen basally, then widely depressed behind the swellings; foveae denser on basal sixth, then moderately but rather irregularly arranged in rows; scales orange yellow, semi-circularly curved, alternating on rows of foveae except for inner 4–5 rows.

Genitalia ( Fig. 116 ) with paramere of tegmen 3.45 times as long as basal width, straightly attenuate apically, 0.17 times as long as tegmen. Median lobe with dorsal plate slightly shorter than ventral plate; basal struts distinctly short, 1/3 length of median lobe. Endophallus ( Fig. 130 ) rather simple and elongate; MPH inflated basally, with a pair of indistinct sclerites, and bent dorsally at a right angle; APH roundly swollen basally; ejaculatory duct thick.

Female: BL= 11.7–12.3 mm. Similar to male in body color, foveae and scales. Antennae with last segment exceeding the elytral apex; scape short and thick, 0.48 times as wide as length, relative lengths of segments from base to apex: 51: 15: 62: 56: 79: 74: 73: 68: 67: 64: 74.

Type material examined. Holotype: ♂, Cameron Highland, 1,600 m, Tanah Rata , Malaysia, 11–27-II-2000, J. Horák leg. ( PCCH) . Paratype: 1♀, Pahan, Cameron Highland, 1.600 m, Tanah Rata, Malaysia, 11–27-II-2000, P. Pacholátko leg. ( PCCH).

Other material examined. 1♂, Tanah Rata, Cameron Highland, Pahang, Malaysia, 8- III-2 0 13, R. Okano leg. ( EUMJ); 1♀, Cameron Highland, 4°28'05.5"N 101°23'21.9"E, alt. 1,438 m, Pahang, Malaysia, 5-III-2015, H. Ikeda leg. ( EUMJ).

Distribution. Malaysia (Pahang).

Remarks. This species is easy to distinguish from the other members of the genus by the distinct lateral tubercles of pronotum, orange colored scales and pubescence, and the broadly depressed elytral disk.
