Abstract
The species of the hoverfly genus Paramixogaster Brunetti, 1923 from the Oriental Region are revised. The resulting number of valid species is 15, of which the following four are described as new: P. halmaherensis Reemer, sp. nov., P. jubata Reemer, sp. nov., P. kodaiana Sankararaman & Reemer, sp. nov., and P. sulawesiana Reemer, sp. nov. Three new synonymies are established: Paramicrodon decipiens de Meijere, 1917, syn. nov. is a junior synonym of Microdon vespiformis de Meijere, 1908; Paramixogaster wegneri Keiser, 1964, syn. nov. is a junior synonym of Ceratophya indica Doleschall, 1857; Microdon subpetiolatus Thompson, 2020, syn. nov. is a junior synonym of Microdon contractus Brunetti, 1923. Paramixogaster huoi Reemer, nom. nov. is introduced as a replacement name for P. trifasciatus Huo & Zhao, 2022, which is a primary homonym of P. trifasciatus Ssymank & Reemer, 2016. Neotypes are designated for Paramixogaster icariiformis Pendlebury, 1927 and Myxogaster variegata Sack, 1922, and a lectotype is designated for Microdon vespiformis de Meijere, 1908. An identification key to the species and diagnoses for all species are provided.
