Oxus crassiseta Cook, 1986 and O. cormela Cook, 1986 have both four pairs of glandularia in the expanded coxal area. Two Australian species with five pairs of glandularia in the expanded coxal area, O. zunova (Cook, 1986) and O. setipalpis (Cook, 1986) have the dorsal strip with a median sclerite. A rheophilic species, occurring in streams.
