Etymology.
The specific name is derived from the Greek word “
erromena
”, meaning brawny, and refers to the shape of the male palp.

Diagnosis.
The new species is somewhat similar to
B. banlakwo
Huber, 2005
, but can be distinguished by the shapes of the marks on the male carapace, the procursus (
Figs 7
D–E) and the position and distance between the female epigynal pocket (
Figs 7
F–G).
Description.
Male (
holotype
). Total length 2.00 (2.25 with clypeus), carapace length 0.83, width 0.72. Leg I: 7.25 (1.84 + 0.26 + 2.00 + 2.20 + 0.95), tibia II: 1.21, tibia III: 0.83, tibia IV: 1.42; tibia I L/d: 20. Habitus as in
Fig. 7
A, carapace pale brown, with brown marks medially connecting to ocular area; abdomen ochre-grey, without marks. Ocular area not elevated, thoracic furrow absent. Clypeus unmodified. Sternum slightly wider than long (0.57/0.47). Chelicerae as in
Fig. 7
B, with pair of proximal small rounded projections laterally, and distally a pair of curved apophyses. Retrolateral trichobothrium of tibia I at 45%; legs brown without spines and curved hairs, with vertical hairs proximally on all metatarsi; tarsus I with 10 pseudosegments, quite distinct distally. Palps as in
Figs 7
C–E, trochanter with short retrolateral apophysis; femur with distinct hump proximo-dorsally; procursus complicated distally, with brush-shaped processes and absent dorsal spine; bulb with broad hooked apophysis and embolus with transparent spine (
Fig. 7
D).
Female: In general similar to male. Tibia I in
6 females
: 1.74–2.04 (mean 1.88). Epigynum simple externally, with pair of pockets medially (
Fig. 7
F). Dorsal view as in
Fig. 7
G, with pair of triangular pore plates.
Variation
. Body length in the other males: 2.12. Tibia I in the other males: 2.05.

locality.
