subdistinctus Richards, 1928a:333, examined

TAXONOMIC STATUS: The taxa melanurus, difficillimus, and tschitscherini have been treated both as conspecific and as separate species (Williams, 1991 [pdf]). Aside from differences in colour pattern, they are closely similar in morphology.
Nonetheless, B. melanurus can be differentiated by the morphology of the male genitalia (Williams, 1991 [pdf]). Evidence from comparisons of 16S gene sequences is consistent with B. melanurus and B. difficillimus being separate species (Cameron et al., 2007 [pdf]). A study of larger samples of COI barcodes (Williams et al., 2011 [pdf]) supports the interpretation that B. melanurus is a broadly distributed species that includes the taxon tschitscherini, while B. difficillimus is well supported as a separate species. It remains possible that the taxon tschitscherini might be considered a separate species, depending on which species concept is applied.
DISTRIBUTION: Oriental, Palaearctic Regions.
