A generic classification of the tribe Discocerinini (Diptera : Ephydridae)

Broad descriptions of the genera of Discocerinini are provided for the firs t time. Two new genera are described: Galaterina with type species G. noona dan sp. nov. from Papuan Region and Orasiopa with type species O. millennic a sp. nov. from Australasian Region. Lamproclasiopa Hendel is recognized as a genus (with Basila Cresson as its new synonym). Eleven new combinations are proposed: one in Discocerina, nine in Lamproclasiopa, one in Orasiopa. A phylogenetic reconstruction based predominantly on male terminalia is giv en. Eleven taxa treated as genera are grouped into three lineages. Gymnocla siopa (most plesiomorphous, monotypic), Diclasiopa-group (intermediate with following genera: Diclasiopa, Ditrichophora, Hecamedoides, Pectinifer), an d Discocerina-group (most apomorphous with following genera: Discoerina, Ga larterina, Hydrochasma, Lamproclasiopa, Orasiopa, and Polytrichophora).
