| Malesia harbours one, possibly two species of Blachia. In the Philippines B. philippinensis is found and this species is not synonymous with B. andamanica. In literature B. andamanica has been recorded for west Malesia, but no specimens were seen. Based on its presence in Peninsular Thailand and the Andamans it is likely to be present in Peninsular Malaysia. The most distinct difference between both species is in the indumentum of the ovary, sparsely hairy in the lower half versus densely and completely sericeous, respectively. |
