Distribution and biology.
China
(
Guangdong
,
Hainan
,
Hong Kong
). The nymphs usually inhabit the stone surfaces in slow current streams. Presumably it has a wide geographical range in southern
China
.
Comments.
This species was originally described by
Braasch and Soldán (1980)
based on nymphs from Liu Chui,
China
. Later, Tong
et al.
(2003) redescribed the nymphal stage and provided the description of imagoes reared in the laboratory from mature nymphs, thereby confirming their association. The nymph of
B.
(
C.
)
longisetosa
(
Figs 4–5
) is characterized by the extremely short maxillary palpus (about 1/2 the length of galealacinia) (
Fig. 1
) and abdominal sternites IV–VI each with a pair of long and fine setal tufts (i.e. with contiguous setal bases) (
Fig. 3
). In male imaginal stage, it can be easily separated from the imaginal congeners by the presence of a well-developed rectangular protuberance between the genital forceps bases (Tong
et al
. 2003).
