Palp and leg measurements: palp 8.4 (3.1, 1.3, 1.3, -, 2.7), I 20.6 (5.8, 3.0, 5.4, 4.8, 1.6), II 19.2 (5.4, 3.4, 4.6, 4.2, 1.6), III 16.1 (5.0, 2.3, 3.3, 4.1, 1.4), IV 22.4 (6.5, 2.4, 5.2, 6.4, 1.9). Leg formula 4123. Spination of palp and legs: palp 161, 100, 1010; femora I p031, d111, r1111, II-III p112, d111, r112, IV p112, d111, r002; patellae 101; tibiae I p110, d111, r1111, v22222, II p110, d111, r110, v22222, III p11, d111, r11, v222, IV p11, d112, r11, v222; metatarsi I-II p111, r111, v222, III p112, d010, r112, v222, IV p112, d010, r112, v2222. Chelicerae with 3 promarginal, 4 retromarginal teeth, without denticles. Retromargin of chelicerae close to fang base with 7 bristles. Ventral tarsi and metatarsi I-II with sparse scopula. Right leg claws I and IV with 3 secondary teeth, claws II and III with 2 secondary teeth.

Palp (Fig. 3 a-c). Palpal tibia with strong RTA and with three apices distally. Cymbium tip slightly conical and with pointed retro-proximal cymbial outgrowth. Embolus arising at 7.30- o’clock-position, short, its tip situated in distal half of tegulum (Fig. 8 a). Conductor arising at 12- o’clock-position subdistally. Tegular apophysis almost kidney-shaped in ventral view and arising subcentrally from tegulum.

Colour (Fig. 9 b). Reddish-brown to yellowish with dark patterns. Dorsal prosoma with characteristic slightly lighter median band, widened behind eyes and with some white hairs, distinctly marked fovea and indistinct radial markings. Sternum and ventral coxae brown, gnathocoxae and labium brown with dark patterns. Chelicerae reddish-brown with longitudinal lines. Leg reddish brown-yellowish. Dorsal opisthosoma yellowish with black patches, most fused into two parallel rows. Lateral opisthosoma yellowish with darker spots. Ventral opisthosoma yellowish with dark patterns; epiandrium and muscle sigilla light. Anterior lateral spinnerets dark, posterior lateral and median spinnerets and anal tubercle light.

Female

Unknown.

Variation: Paratype males (IZCAS-Ar 43474-43477): PL 7.5-8.0, OL 5.8-5.9.

Diagnosis

Medium Ctenidae (total length male 13.3-14.1). The new species is assigned to the robustus species-group because of the following characteristics: stout TA; simple stout embolus with broad base and short apical part; presence of retro-proximal cymbial outgrowth; RTA arising medially to subdistally from palpal tibia. Additionally, it resembles B. candidate Jäger, 2022 (see Jäger 2022: figs. 254-262, 280-284) by having similar tegular apophysis and embolus, but it can be distinguished by the cymbium with retro-proximal protuberance (arrowed in Fig. 3 b and c; absent in B. candidate ), by the retro-proximal cymbial outgrowth small and pointed (Fig. 3 b and c; relatively large and blunt in B. candidate ) and by the RTA broad in distal part and with three apices distally (Fig. 3 b and c; RTA narrow in distal part and with tooth in middle of RTA tip and tibia in B. candidate ).

Etymology

The specific name refers to the type locality and is a noun in apposition.

Distribution

Vietnam (Hai Phong, type locality, Fig. 1 ).
