( Figs 12, 13 , 52 , 68 , 84 , 100 )

Caraphia minor Gahan, 1906: 76 (Type locality: "Karen Mts., Burma (current Myanmar)"); Aurivillius, 1912: 177; Boppe, 1921: 52; Hayashi & Villiers, 1985: 24, 25; Chou & N. Ohbayashi, 2008: 139.

Diagnosis. Female: BL= 9.9 mm; EW= 2.6 mm. Body brownish. Head, pronotum and scape with dense pale yellowish hairs which are relatively long and thin, suberect with bent down tip. Antennae with scape short and thick, 1.80 times as long as wide; relative length of segments from 1st to 6th: 58: 15: 53: 56: 84: 84 (the type specimen lacking left apical 5 segments and right 10 segments). Elytra with foveae arranged in regular rows but more or less irregular beside suture and apical area; scales relatively long and thin, suberect and curved, 2.3 times as long as the diameter of each fovea, alternating on rows of foveae.

Male: Unknown to us.

Type material examined. Lectotype (designated herein): ♀, Karen Mts., Birmah (current Myanmar), Doherty leg. ( Fry Coll. 1905. 100 ) ( BMNH).

Distribution. Myanmar.

Remarks. This rather small species is similar to C. huai sp. nov., but is easy to distinguish by its differently shaped pronotum, apically convergent elytra, and long and slender scales of the elytra.

Only a female syntype specimen was available for study. According to the original description of Gahan (1906), this species was described from two specimens but mainly on a female specimen with the antennae " extending by about the last two joints past the apex of elytra " (several apical segments are lost now). The second specimen (7.5 mm) was considered to be a male (" the male of this species, if I am right in considering as such the smaller of the only two specimens I have seen, differs but little from the female — the antennae are little longer, extending by nearly three joints past the apex of elytra; ..... "). We could not locate this second small specimen, but the female syntype preserved in BMNH fits well the original description, and we designate it as the lectotype in order to stabilize the taxon.
