The family Hippoboscidae, commonly known as “louse flies,” comprises pupiparous Diptera that are ectoparasites of birds and mammals, with significant impacts on their hosts and epidemiological importance. The louse fly fauna of Vietnam is relatively understudied compared to other countries in the Southeast Asia region. In this study, we describe a new species of the genus Icosta Speiser, 1905 (Diptera: Hippoboscidae), Icosta korzuni sp. n., collected from the lesser coucal Centropus bengalensis (Gmelin, JF, 1788) in Cat Tien National Park, Vietnam. This new species is distinguished from other Icosta species by the morphology of laterite 3, wing length, arrangement of wing microtrichia, body coloration, and its geographical distribution. Additionally, we provide an updated key to the subgenus Icosta Speiser, 1905. |
