Abstract

The subfamily Rhynchoproctinae is revised at the generic level. Four new genera and a remarkable new species are described: Alienostreptus, gen. nov. from Vietnam, Armatostreptus, gen. nov., Heptischius, gen. nov., and Heptischius lactuca, sp. nov. from Thailand, and Prominulostreptus, gen. nov. from China. Agaricogonopus Zhang and Zhang, 1997, is removed from synonymy with Junceustreptus Demange, 1961. All 14 genera of the subfamily share three diagnostic gonopodal characters: the posterior surface of the anterior coxal fold forms a deep concavity, there is a mesal flap on the gonopod coxa, and the posterior coxal fold is very low. A cladistic analysis based on morphological data supports monophyly of Rhynchoproctinae and the distincness of the newly described genera. A dichotomous key to the genera is included.
