Diagnosis.
Males are most similar with those of
B. thorelli
Simon, 1901
, but can be recognized for having a broad RTA with sinuous tip (
Fig 17
;
B. thorelli
with narrow, pointed RTA, as in
Żabka 1988
, fig 53). Females are similar to those of
B. annamita
Simon, 1903
, but can be distinguished by a deep, medial pocket and by the indistinct spermathecae (
Figs 18–19
; pocket shallow and wide and spermathecae distinctly globular in
B. annamita
, as in
Żabka 1988
, fig 51).
