Description of adults of Simulium (Simulium) baimaii from Thailand (Diptera: Simuliidae) and its assignment to the malyschevi species-group

Abstract

The adult female and male of Simulium (Simulium) baimaii originally described from the pupal and larval stages from Thailand are described for the first time. This species is assigned to the malyschevi species-group judging from the morphological characteristics of the female and male genitalia, although it has the pupal gill of two carrot-like filaments, a character never before observed in this and other species-groups within the subgenus Simulium s. str.
