Figs 13–15 View FIGURE 13 View FIGURE 14 View FIGURE 15 , 41 View FIGURE 41

Type material. Holotype: Male ( SMF), by hand, at day, vegetation, under stones, dry secondary forest, Phou Salao [15°05.647′N, 105°48.577′E, alt. 150 m], 2.5 km south of Pakse, Champasak, Laos, 14 November 2012, leg. P. Jäger.

Etymology. The specific name is from Latin lancea (spear), in reference to the black spear-shaped apophysis of procursus; noun.

Diagnosis. The species resembles B. sarika ( Huber 2005a: 40, figs 47–48 and 246–249), but can be distinguished by different distal apophyses of male chelicerae ( Figs 14 View FIGURE 14 B and 15C) and spear-shaped distal apophysis of procursus ( Figs 13 View FIGURE 13 A–D and 15A–B).

Description. Male (holotype): Total length 1.55 (1.60 with clypeus), prosoma 0.56 long, 0.41 wide, opisthosoma 0.99 long, 0.57 wide. Leg I: 10.62 (2.69 + 0.24 + 2.78 + 3.80 + 1.11), leg II: 7.20 (1.94 + 0.23 + 1.78 + 2.47 + 0.78), leg III: 4.57 (1.30 + 0.21 + 1.05 + 1.48 + 0.53), leg IV: 6.47 (1.92 + 0.22 + 1.63 + 2.09 + 0.61); tibia I L/d: 56. Habitus as in Figs 14 View FIGURE 14 C–E. Dorsal shield of prosoma and sternum yellowish, without marks. Legs yellowish, without darker rings. Opisthosoma yellowish, without spots. Distance PME-PME 0.13, diameter PME 0.07, distance PME-ALE 0.01, AME absent. Ocular area not elevated. Thoracic furrow absent. Sternum about as wide as long (0.40). Chelicerae as in Figs 14 View FIGURE 14 B and 15C, with a pair of thumb-shaped apophyses proximally and a pair of long, curved apophyses distally (distance between tips: 0.44). Pedipalpi as in Figs 13 View FIGURE 13 A–B and 15A–B; trochanter with a short retrolatero-ventral apophysis; procursus simple proximally but complex distally, with a sclerite and a spear-shaped apophysis; bulb with a wide apophysis and a simple embolus. Retrolateral trichobothrium of tibia I at 17%; legs with short vertical hairs on metatarsi, without spines and curved hairs; tarsus I with about 15 distinct pseudosegments.
