Abstract

The known members of the Hydrellia crassipes species group in North Amerisa are described or redescribed, including H. crassipes Cresson, H. procteri Cresson, H. saltator Deomer, H. amplecta n.sp., H. bryani n.sp., H. ocalae n.sp., and H. tibiospica n.sp. Adults of these species exhibit the following synapomorphies: dilated male metafemur and expanded (and flanged in some) male metatibia and striate (fibrillate) distiphallus. Only a single species (H. tibiospica n.sp.) was reared from its host-plant species, Juncus debilis Gray, but there are associated habitat data to indicate that the entire species group may have sedges and rushes as host plants.
