Simulium (Simulium) atipornae Takaoka, Srisuka & Choochote, 2014:725 –731 (Female, male, pupa and larva).

Specimen examined. One pharate male collected from a slow-flowing forest stream (width 10–20 cm, depth 5–30 cm, water temperature 14.0˚C, shaded, altitude 1,273 m) (16˚11’42.061”N/107˚51’27.955”E), Bach Ma National Park, Phu Loc, Thua Thien Hue Province, central Vietnam, 23-II-2014, by H. Takaoka, M. Sofian-Azirun, Z. Ya’cob, C.D. Chen & K.W. Lau.

Distribution. Thailand and Vietnam (New record).

Remarks. Simulium (S.) atipornae is characterized in the female by the claw with a small subbasal tooth, ovipositor valve triangular with its inner margin nearly straight and its surface covered with many short to mediumlong hairs; in the male by the style with a short subbasal protuberance and ventral plate Y-shaped with a toothed posterior margin; and in the pupa by the head and thoracic integument almost bare, gill with six filaments, and cocoon with anterolateral windows ( Takaoka et al. 2014e).

The pharate male dissected from its pupal case collected from Bach Ma National Park agrees morphologically with the original description ( Takaoka et al. 2014e).

This species is a new record from Vietnam.
