Simulium (Simulium) quasifrenum Delfinado, 1971 

Simulium (Simulium) quasifrenum Delfinado, 1971: 133  –134 (Male); Takaoka, 1983: 131 –134 (Female, male, pupa and larva).

This species was described based on adult males by Delfinado (1971). Its female, pupa and larva were described by Takaoka (1983). This species is similar to S. keningauense  and S. lunduense  in having the pupal thorax with sharply-pointed cone-like tubercles. However, this species is distinguished from S. keningauense  in the female by the relative length of the sensory vesicle against the third palmomere of the maxillary palp (0.29–0.35 in S. quasifrenum  versus 0.42–0.48 in S. keningauense  ) and claw without subbasal swelling (with tiny subbasal swelling in S. keningauense  ); and in the pupa by the angle formed basally by the upper filament of the dorsal pair and the lower filament of the ventral pair when viewed laterally (80 or more degrees in S. quasifrenum  versus 30–40 degrees in S. keningauense  ).

This species is distinguished from S. lunduense  in the male by the relative length of the hind basitarsus against its greatest width (3.7 in S. quasifrenum  versus 4.5–4.6 in S. lunduense  ) and in the pupa by the relative length of the anterodorsal trichomes against the frontal trichoms (1.0– 1.4 in S. quasifrenum  versus 0.6 in S. lunduense  ).
