REMARKS
This monotypic genus is tentatively regarded as distinct from
Dayus
. It differs only in having the basal group setae of the subgenital plate blunt-tipped (also found in some
Homa
species
) and distal macrosetae more numerous (
Fig. 3L
) and in lacking an unusual ventral apodeme of the 8
th
abdominal sternite, found in
Dayus
. In other respects, it is similar to
Dayus
in its overall red colour, having the 3rd apical cell in the forewing petiolate (
Fig. 3C
), male pygofer with processes (
Fig. 3G
), form of the subgenital plate and aedeagus and well developed male basal dorsal abdominal apodemes (
Fig. 3M
). The genus was redescribed by
Yu & Yang (2013)
as there were some errors in Mahmood’s original description and figures, which also had implications on subsequent studies (see Remarks under
B. rufa
below).
Yu & Yang (2013)
also noted that
Dworakowska (1973)
had stated (and figured) that the facial laterofrontal sutures were absent in
Baguoidea
but were present in their specimens, and are also present in the specimens studied here. This apparent mistake by Dworakowska may have been due to the sutures being obscure against the red facial colour.
