Revision of the horse fly genera Lissimas and Cydistomyia (Diptera: Tabanidae: Diachlorini) of Australia

Abstract

Two genera of horse flies of the Tribe Diachlorini (Tabanidae), Lissimas Enderlein and Cydistomyia Taylor in Australia, are reviewed and diagnosed. Lissimas australis (Ricardo), the sole species in the genus in Australia, is redescribed. A key is given to 39 Cydistomyia species, among them 22 established species are redescribed and 17 species are described as new. The new species are: Cydistomyia danielsorum, C. fergusoni, C. tasmaniensis, C. hardyi, C. exemplum, C. obscurus, C. sabulosus, C. monteithi, C. curvabilis, C. pilosus, C. triangularis, C. improcerus, C. fenestra, C. pruina, C. infirmus, C. innubilus, and C. pseudobrevior. Six possible new species are described briefly but not named.
