Type material. Holotype: Male ( SMF), secondary forest (3°43’06.30”N, 101°45’09.86”E, elevation 1300 m), Telecom loop, Fraser’s Hill, Pahang, Malay Peninsula, Malaysia, 16 February 2015, P. Jäger & T. Laufs leg. GoogleMaps Paratype: 1 female ( SMF), same data as holotype GoogleMaps .
Etymology. The specific name is a patronym in honor of the collector Peter Jäger; noun (name) in genitive case.
Diagnosis. This species resembles B. fraser Huber, 2005 (see Huber 2005: 51, figs 69, 320–324) and B. xiaolongha Zhu & Li, 2021 (see Zhu & Li 2021: 561, figs 3– 4, 5E –F) with the elongated bulbal apophyses ( Fig. 6D View FIGURE 6 ), but males can be distinguished by brown marks on the clypeus ( Fig. 6I View FIGURE 6 ). They also can be distinguished from B. fraser by having the cheliceral distal apophyses directed laterally (arrow da in Figs. 6C View FIGURE 6 , 15C View FIGURE 15 ; distal apophyses directed anteriorly in B. fraser ), and females can be distinguished by having frontal “epigynal” pockets laterally on the sclerotized plate (arrow ep in Figs 6A–B View FIGURE 6 , 14E–F View FIGURE 14 ) and curved vulval pore plates (arrow pp in Figs 6B View FIGURE 6 , 14F View FIGURE 14 ). Females differ from B. xiaolongha by the semicircular flap and by a distal spine seen in retrolateral view of the procursus ( Figs 5B, 5D View FIGURE 5 , 13F View FIGURE 13 ; narrow flap in B. xiaolongha ).
Description. Male (holotype): Total length 2.03 (2.19 with clypeus), carapace 0.88 long, 0.78 wide, opisthosoma 1.31 long, 0.88 wide. Leg I missing, leg II: 14.71 (3.85 + 0.40 + 3.53 + 5.58 + 1.35), leg III: 9.02 (2.56 + 0.30 + 2.12 + 3.21 + 0.83), leg IV: 12.53 (3.53 + 0.34 + 3.21 + 4.49 + 0.96). Distance PME-PME 0.11, diameter PME 0.06, distance PME-ALE 0.09, AME absent. Habitus as in Figs 6E–F View FIGURE 6 . Carapace pale, with brown lateral margins. Ocular area not elevated. Clypeus ( Fig. 6I View FIGURE 6 ) with brown marks, unmodified. Chelicerae ( Figs. 6C View FIGURE 6 , 15C View FIGURE 15 ) with pair of small proximo-lateral apophyses and pair of long, curved distal apophyses, each with sclerotized and pointed tip (distance between tips of distal apophyses: 0.62). Sternum pale, slightly wider than long (0.63/0.56). Thoracic furrow absent. Legs pale, but dark brown on femur, patellae and tibia-metatarsus joints, without darker rings. Opisthosoma pale, without spots. Palps as in Figs 5A–B View FIGURE 5 ; coxa unmodified; trochanter with short retrolatero-ventral apophysis; femur with small ventral hump (arrow 1 in Fig. 5B View FIGURE 5 ) and small proximo-dorsal apophysis (arrow 2 in Fig. 5B View FIGURE 5 ); procursus ( Figs 5A–D View FIGURE 5 , 13E–F View FIGURE 13 ) simple proximally but complex distally, with curved subdisto-dorsal sclerite (arrow 1 in Figs 5C View FIGURE 5 , 13E View FIGURE 13 ), long disto-prolateral spine (arrow 2 in Figs 5C View FIGURE 5 , 13E View FIGURE 13 ), long subdisto-prolateral sclerite (arrow 3 in Figs 5C View FIGURE 5 , 13E View FIGURE 13 ), disto-retrolateral membranous lamella (arrow in Figs 5D View FIGURE 5 , 13F View FIGURE 13 ) and semicircular retrolateral membranous flap (arrow f in Figs 5D View FIGURE 5 , 13F View FIGURE 13 ); bulb ( Fig. 6D View FIGURE 6 ) with hooked apophysis and simple embolus. Legs with short vertical setae on metatarsi, without spines and curved setae.
Female: Similar to male, habitus as in Figs 6G–H View FIGURE 6 . Total length 2.22 (2.31 with clypeus), carapace 0.84 long, 0.88 wide, opisthosoma 1.47 long, 0.91 wide. Tibia I: 4.17; tibia I L/d: 42. Distance PME-PME 0.16, diameter PME 0.09, distance PME-ALE 0.09, AME absent. Sternum slightly wider than long (0.59/0.50). Clypeus pale, without marks. External female genitalia ( Figs 6A View FIGURE 6 , 14E View FIGURE 14 ) simple and flat, with pair of frontal “epigynal” pockets (arrow ep in Figs 6A–B View FIGURE 6 , 14E–F View FIGURE 14 ), 0.54 apart. Vulva ( Figs 6B View FIGURE 6 , 14F View FIGURE 14 ) with pointed anterior arch and pair of large, curved and oval pore plates (arrow pp in Figs 6B View FIGURE 6 , 14F View FIGURE 14 ), without serrated sclerites.
Natural history. The species was found in secondary forest, on embankments along the road at night and collected by hand.
Distribution. Malaysia (Malay Peninsula, type locality only; Fig. 16 View FIGURE 16 ).
