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
B and 15C) and spear-shaped distal apophysis of procursus (
Figs 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

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
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
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.
