7. Simulium (Simulium) brevipar Takaoka & Davies, 1995

Simulium (Simulium) brevipar Takaoka & Davies, 1995: 132–137 (Female, male, pupa and larva).

Specimens examined. Two females, one male (all reared from pupae and preserved with their pupal exuviae and cocoons in vials with 80% ethanol) and two mature larvae (preserved in a vial with 80% ethanol), collected from the same small stream as noted under the holotype of S. (G.) hongthaii sp. nov.

Distribution. Malaysia, Thailand, Vietnam (new record).

Remarks. This species belongs to the Simulium tuberosum species-group. The pupa of this species is characterized by the thoracic integument with a pit-like organ near the base of the gill on each side, and six gill filaments all directed forward (Takaoka & Davies 1995). The females, male, pupae and larvae agree with those of the original description (Takaoka & Davies 1995).
