Holotype male, Thailand ( NMNS), by original designation. For details see Type material below. ventral finger.

Diagnosis. Male. Length: 11mm. Frons at vertex / head width ratio: 0.280 (n=1). Lunula bare. Fronto-orbital plate without proclinate orbital setae. Anepimeron mostly covered with densely set black ground setulae, many reaching katepisternum. Only very few yellow ground setulae in lower hind part (close examination necessary). Femora darkened along upper side, fore femur also on anterior side, mid femur darkened all around. Fore tibia without ventral spine-like setae ( Fig. 180 View FIGURES 173–186 ). Mid tibia without fringe ( Fig. 193 View FIGURES 187–198 ). Hind tibia without fringe, only a row of 4–6 thin av setae ( Fig. 205 View FIGURES 199–210 ).

ST5 flap ( Fig. 116 View FIGURES 109–118 ) broad, slightly asymmetric, with diverging lateral edges, and a deep excavation in hind edge.

Cerci strongly curved in profile view ( Fig. 115 View FIGURES 109–118 ). Surstylus bare below. Distiphallus with horizontal dorsolateral wings. Antlers simple, with no basal tooth. Upper lip not projecting beyond base of antlers. Distal edge of upper lip straight in dorsal view. Vertical sclerotised sheet prominent, with a depression in the anterior edge above the lateral finger. External hypophallic lobe folded in anterior part and forming an almost transverse forwardly facing wall with a strongly projecting and pointed ventral finger. Internal hypophallic lobes converging. Parastomal sclerites ( Figs. 110, 111, 117 View FIGURES 109–118 ) long, originating close together just below upper lip, curved, with concavity forwards, a small forward projection present slightly below middle.

Female. Unknown. I expect the female of B. pseudovaricolor to be recognisable (and separable from the female of B. taksina ) based on a relatively narrow frons and the mostly black vestiture on the anepimeron reaching katepisternum (like the males).

Distribution. Thailand.
