Discussion.
The small size and coloration are usually enough to distinguish this species from other species of the genus. Some specimens from
Guatemala
display the darker dorsal coloration that was previously described by
Leng (1911)
as the species
B. duodecimguttata
. The
holotype
of
B. duodecimguttata
is a female; the genitalia of male specimens with morphology similar to that described by
Leng (1911)
were dissected and no differences were found from that of
B. lepida
. Therefore,
B. duodecimguttata
should be considered a junior synonym of
B. lepida
.
