Type material. Holotype: male (NMK-Ar29685), Mzima Springs (2°59.049′S, 38°1.383′E, elev. 684 m), Tsavo West National Park , Mtito Andei Town, Taita-Taveta County, Kenya, 27 July 2016, G.M. Kioko, Z. Yao and Q. Zhao leg. GoogleMaps Paratypes: 2 males and 3 females (NMK-Ar29686–29690), same data as holotype GoogleMaps .

Etymology. The specific name is a patronym in honor of the collector Qingyuan Zhao, and is a noun (name) in genitive case.

Diagnosis. This species resembles B. nigrescens Berland, 1920 (see Huber 2003: 568, figs 6, 30, 92–98) with similar procursus ( Figs 1 View FIGURE 1 A–D) and epigynum ( Fig. 2A View FIGURE 2 ) but can be distinguished by males with pedipalpal femur with proximo-dorsal apophysis (arrow in Fig. 1B View FIGURE 1 ). In addition, males present larger cheliceral proximo-lateral apophysis ( Figs 2 View FIGURE 2 D–E), extremely swollen cheliceral frontal apophysis with distal projection ( Fig. 2E View FIGURE 2 ), and relatively short and wide bulbal apophysis ( Fig. 2C View FIGURE 2 ) than B. nigrescens ; and females present larger pore plates than B. nigrescens ( Fig. 2B View FIGURE 2 ).

Description. Male (holotype): Total length 2.13 (2.50 with clypeus), carapace 0.66 long, 0.91 wide, opisthosoma 1.47 long, 1.14 wide. Leg I: 22.01 (5.45 + 0.44 + 5.64 + 8.08 + 2.40), leg II: 14.02 (3.85 + 0.45 + 3.44 + 4.87 + 1.41), leg III: 10.69 (3.01 + 0.36 + 2.66 + 3.64 + 1.02), leg IV: 13.54 (3.97 + 0.40 + 3.36 + 4.84 + 0.97); tibia I L/d: 56. Distance PME-PME 0.18; diameter PME 0.06; distance PME-ALE 0.02; AME absent. Sternum wider than long (0.70/0.63). Habitus as in Fig. 2F View FIGURE 2 . Carapace yellowish, with dark brown lateral marks; ocular area, clypeus and sternum dark brown. Legs yellowish, but slightly whitish on distal parts of femora and tibiae, with darker rings on subdistal parts of femora and tibiae. Opisthosoma yellowish, with distinctive dark brown pattern. Ocular area slightly elevated. Thoracic furrow absent. Chelicerae as in Figs 2 View FIGURE 2 D–E, with pair of proximo-lateral apophyses, pair of extremely swollen frontal apophyses, each provided with small projection and strong modified setae distally, and pair of distal apophyses, each provided with four teeth. Pedipalps as in Figs 1 View FIGURE 1 A–B; coxa with ventral apophysis; trochanter with retrolatero-ventral apophysis; femur with large proximo-dorsal apophysis (arrow in Fig. 1B View FIGURE 1 ); trichobothria on tibia very distal; procursus simple, with three membranous process distally; bulb with weakly sclerotized embolus and short apophysis provided with two small apophyses (arrows in Fig. 2C View FIGURE 2 ). Retrolateral trichobothrium of tibia I at 6%; legs with vertical setae on metatarsi, without spines and curved setae; tarsus I with 12 distinct pseudosegments.

Female: Similar to male, habitus as in Figs 2 View FIGURE 2 G–I. Total length 2.02 (2.38 with clypeus), carapace 0.55 long, 0.86 wide, opisthosoma 1.47 long, 1.13 wide; tibia I: 4.87; tibia I L/d: 51. Distance PME-PME 0.15; diameter PME 0.06; distance PME-ALE 0.04; AME absent. Sternum wider than long (0.58/0.50). Epigynum ( Fig. 2A View FIGURE 2 ) with straight scape anteriorly. Vulva ( Fig. 2B View FIGURE 2 ) with pair of large pore plates.

Distribution. Kenya (Taita-Taveta, type locality; Fig. 7 View FIGURE 7 ).
