The phylogenetic relationships of members of Eudorylini (Diptera: Pipunculi
dae: Pipunculinae) were explored. Two hundred and fifty-seven species of Eu
dorylini from all biogeographical regions and all known genera were examine
d. Sixty species were included in an exemplar-based phylogeny for the tribe
. Two new genera are described, Clistoabdominalis and Dasydorylas. The iden
tity of Eudorylas Aczel, the type genus for Eudorylini, has been obscure si
nce its inception. The genus is re-diagnosed and a proposal to stabilize th
e genus and tribal names is discussed. An illustrated key to the genera of
Pipunculidae is presented and all Eudorylini genera are diagnosed. Numerous
new generic synonyms are proposed. Moriparia nigripennis Kozanek & Kwon is
preoccupied by Congomyia nigripennis Hardy when both are transferred to Cl
araeola, so Cla. koreana Skevington is proposed as a new name for Mo. nigri
pennis.
