12. Simulium (Gomphostilbia) tekamense Takaoka, Sofian-Azirun & Ya’cob, 2014

Simulium (Gomphostilbia) tekamense Takaoka, Sofian-Azirun & Ya’cob, 2014b: 473–476 (Female and pupa).

This species was described by Takaoka et al. (2014b). Its male and larva remain unknown. It was tentatively placed in the S. binuanense subgroup by having eight filaments, of which two filaments of the ventral pair are longer than the pupal body, and somewhat different in length and thickness from each other, and two filaments of the middle triplet are over the half of the length of the ventral paired filaments, as defined by Takaoka (2012).

The female of this new species is most remarkable in that it has the subcosta which bears no or two hairs, a character rarely found in the S. batoense species-group.

The pupae were collected from a lowland stream in an oil palm plantation in Pahang.
