Meuffels & Grootaert, 2003: 235, Figs. 229-234.

Teuchophorus species A - Evenhuis & Grootaert, 2002: 316. Material examined. – SINGAPORE: 2 males, Labrador Park , 7 Oct.2000 (20035, coll. P. Grootaert & N. Evenhuis; species A in Evenhuis & Grootaert, 2002) ; 2 males, Labrador Park , 31 Jul.2005 (sample no. 25275, coll. P. Grootaert, Si 929) ; 2 males, Semakau Island , sandy beach near mangrove, 10 Mar.2005 (25009, coll. P. Grootaert, Si 403) .

MALAYSIA: 2 males, 5 females, Langkawi , Burau Bay, 4 Sept.2005, sandy beach (25327, coll. P. Grootaert; all extracted for DNA sequencing) .

Diagnosis. – Third antennal segment about 1.5 times as long as wide ( Fig. 48 ). No stigma : costa darkened, not thickened. First tarsomere of fore leg with a basal spinule. Mid femur at base with about 5-6 bristles, shorter than femur is wide. Mid tibia with black spinules ventrally in apical third. Hind femur without bristles, apart from some anteroventral preapicals. Hind tibia with at least 6 long dorsal bristles. Subapical comb on hind tibia with some dark, thickened bristles ( Fig. 49 ).

Discussion. – This species comes close to T. simplicissimus and belongs to the group of species with a row of ventral spinules on the apical third of the mid tibiae. The black bristles in the posteroventral comb on hind tibia are unique in Teuchophorus and thus an easy character for identification.

Distribution and habitat. – South Thailand, Singapore. Rare; on sandy beaches where it prefers wet, shady areas.
