Abstract
A new genus and two new species of Alluroididae are described from Guyana and additional data are provided for two previously known species. Brinkhurstia donaldin. sp. is characterized by very long ribbon-like penial chaetae and an unpaired spermatheca with a sperm-filled diverticulum and opening mid-dorsally at 7/8. Righiella n. gen. is metandric and without penial chaetae; R. jamiesoni n. sp. has a large, unpaired spermatheca (devoid of diverticula) which also opens mid-dorsally at 7/8. Brinkhurstia donaldi and Righiella jamiesoni were found in running waters in creeks, whereas Brinkhurstia americana (Brinkhurst, 1964) and Kathrynella guyanae Omodeo, 1996 were collected in anoxic mud in a pool.
