ABSTRACT
The new genus Rheocyclops is proposed to accommodate the cyclopoid copepods Diacyclops virginianus Reid, from Virginia, and the new species R. carolinianus from South Carolina, R. talIadega and R. hatchiensis from Alabama, and R. Indiana from Indiana, U.S.A. Most species were collected from the hyporheic zones of stream beds, except R. Indiana which was found in a drip pool in a cave. The new genus is distinguished by a combination of characters: anal operculum produced; antennule II -segmented; antenna lacking exopodite seta; rami of legs 1-4 all 3-segmented, or some rami 2-segmented; leg 5 with proximal segment fused to somite and reduced to small protrusion bearing seta inserted near distal (free) segment, and free segment cylindrical with 2 terminal setae.
