Abstract

Two species of the heptageniid mayfly genus Thalerosphyrus Eaton, T. vietnamensis (Dang) and T. separatus n. sp., are described from Vietnam. Thalerosphyrus separatus can be distinguished by the basally detached posterolateral expansions of pronotum in larva and by the Y -shaped penes in male adult. Their larval and adult stages are described with line-drawings of diagnostic characters. Their diagnoses, distributions, habitat and ecological data, and taxonomic remarks are provided.

Thalerosphyrus에 속하는 2종의 베트남산 납작하루살이 Thalerosphyrus vietnamensis (Dang)과 신종인 T. separatus n. sp.를 기재하였다. 신종인 T. separatus의 유충은 앞가슴 등판의 후측팽창부가 기부에서 분리되어 있고, 수컷성충은 Y자 모양의 음경으로 구별된다. 두 종의 유충 및 성충기에 대하여 진단형질의 삽화와 함께 기재하였고, 진단문, 분포, 서식처와 생태자료, 분류적 고찰을 제공하였다.
