Type material. Holotype: Male ( IZCAS Ar41910), roadside between Wasadum and Ziradum (27°29’48.78”N, 97°10’15.90”E, elevation 874 m), Putao, Kachin, Myanmar, 07 May 2017, Z. Chen & J. Wu leg. GoogleMaps

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

Diagnosis. This species resembles B. pianma Huber, 2005 (see Huber 2005: 14, figs 5, 6, 56, 88–92, 112–130) with the elongated distal apophyses on the male chelicerae ( Figs. 10B View FIGURE 10 , 15E View FIGURE 15 ) but can be distinguished by the presence of a subdisto-ventral membranous lamella (arrow 3 in Figs 9C View FIGURE 9 , 13I View FIGURE 13 ) on the procursus, a pair of angular apophyses on the bulbal apophyses (arrow in Figs 10A View FIGURE 10 ), the absence of a ventral hump on the palpal femur and a pair of apophyses on the clypeus.

Description. Male (holotype, IZCAS Ar41910): Total length 1.60 (1.66 with clypeus), carapace 0.66 long, 0.66 wide, opisthosoma 1.00 long, 0.53 wide. Leg I: 11.39 (3.00 + 0.17 + 2.97 + 4.09 + 1.16), leg II: 7.65 (2.03 + 0.15 + 1.91 + 2.72 + 0.84), leg III: 4.85 (1.41 + 0.09 + 1.13 + 1.59 + 0.63), leg IV: 8.04 (2.28 + 0.16 + 1.94 + 2.75 + 0.91); tibia I L/d: 50. Distance PME-PME 0.14, diameter PME 0.06, distance PME-ALE 0.09, AME absent. Habitus as in Figs 10C–E View FIGURE 10 . Carapace pale. Ocular area not elevated. Clypeus unmodified. Chelicerae ( Figs. 10B View FIGURE 10 , 15E 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: 0.39). Sternum pale, approximately as wide as long (0.41). Thoracic furrow absent. Legs pale. Opisthosoma pale, without spots. Palps as in Figs 9A–B View FIGURE 9 ; coxa unmodified; trochanter with short retrolatero-ventral apophysis; femur with retrolatero-dorsal apophysis (arrow in Fig 9B View FIGURE 9 ); procursus ( Figs 9A–D View FIGURE 9 ) curved (arrow in Fig. 9A View FIGURE 9 ), complex distally, with droplet-shaped subdisto-dorsal sclerite (arrow 1 in Figs 9C View FIGURE 9 , 13I View FIGURE 13 ), small subdisto-prolateral sclerite (arrow 2 in Figs 9C View FIGURE 9 , 13I View FIGURE 13 ), semicircular subdisto-prolateral membranous lamella (arrow 3 in Figs 9C View FIGURE 9 , 13I View FIGURE 13 ), subdisto-ventral membranous lamella (arrow in Figs 9D View FIGURE 9 , 13J View FIGURE 13 ) and with retrolateral membranous flap (arrow f in Figs 9D View FIGURE 9 , 13J View FIGURE 13 ); bulb ( Fig. 10A View FIGURE 10 ) with hooked apophysis (pair of angular apophyses subdistally, arrow in Figs 10A View FIGURE 10 ) and simple embolus. Retrolateral trichobothria of tibia Iat 6% proximally; legs with short vertical setae on metatarsi, without spines and curved setae; tarsus Iwith 15 distinct pseudopodomeres.

Female: Unknown.

Natural history. The species was found on domed webs attached to the underside of leaves.

Distribution. Myanmar (Kachin, type locality only; Fig. 16 View FIGURE 16 ).
