Figures 1–13

TYPE LOCALITY: Tam Dao , Province Vinh Phu, Vietnam.

DIAGNOSIS: As for the genus (see above).

DESCRIPTION: Male. BL 6.0 mm, BW 2.5 mm; body form elongate oval and somewhat depressed; overall coloration brown except vertex black; antennal scape and pedicel brown, flagellar articles dark brown; elytra brown, looking darker from basal fifth to apices due to shadows of hind wings; venter brown throughout. Head with vertex and beyond exposed from above, not hidden by pronotum; vertex flat between eyes, surface glabrous, densely punctate and pubescent. Distance between compound eyes about twofifths of greatest width of head in dorsal aspect, one-fifth in frontal aspect (fig. 7), and one-sixth in ventral aspect. Antennae (fig. 6) with scape elongate quadrate in dorsal aspect, about as long as first flagellar article (FA1); FA1–3 each subequal in length, 4–8 each subequal in length and shorter than 1–3; FA 9 (terminal antennomere) spindle-like.

Pronotum subparallel-sided; posterior angles sharply cornered; punctures on disc separated by about their own diameter (fig. 2). Scutellum large and triangular in shape. Elytra with well-defined lateral margins; surface more or less shagreened, densely setose, costae insignificant except sutural costae. Elytral epipleuron (fig. 5) deeply folded, lying in ventral side of elytra and nearly invisible from lateral aspect, about onesixth of elytral length. Mesoventrite (fig. 4) broadly V-shaped. Central longitudinal sulcus of metaventrite obsolete. Abdominal T8 (fig. 10) broadly rounded apically and slightly emarginate medioapically, S8 (fig. 11) subtrapezoidal. PW/PL 5 1.4; EL/EW 5 3.3; EL/PL 5 3.4; BW/PW 5 1.5.

Aedeagal sheath (fig. 12) about 0.7 mm long, 0.4 mm broad; syntergite slightly surpassing apex of S9; T9 about as long as T10; T10 triangular; S9 setose in apical one-third, rounded at apex, tapering toward base. Genitalia (fig. 13) about 0.5 mm long, 0.3 mm broad; median lobe parallel sided in basal half and gradually tapering apically in dorsal aspect; paramere weakly sclerotized apically but strongly so in posterior margin; dorsum forming a widely V-shaped band connecting with median lobe; basal piece about as long as median lobe, bilaterally symmetric, roughly a V-shaped band, slightly pointed apically.

Female. Unknown.

TYPE MATERIAL: Holotype, male; ‘‘N. Vietnam 1985, pr. Vinh phu, Tam dao 3.6.- 11.6. V. Švihis lgt.’’. The holotype will be preserved in the National Museum of Natural Science, Taichung City, Taiwan ( NMNS) .

ETYMOLOGY: The specific epithet refers to the light brown coloration of the species.
