UROGYRUS CHICHLIDARUM GEN-NOV, SP-NOV, UR OGYRIDAE FAM NOV, PARASITICMONOGENEAN FOUND IN THE URINARY-BLADDER OF CAMEROON CICHLIDAE

Urogyrus cichlidarum gen.nov., sp.nov. (Dactylogyridea, Urogyridae fam .nov.) is proposed for a monogenean found in the urinary bladder of Ch romidotilapia batesi Boulenger, 1901, Nanochromis caudifasciatus Boule nger, 1913, Pungu maclareni Trewavas, Green and Corbet, 1972, Stomatep ia pindu Trewavas, Green and Corbet, 1972, and Tilapia sp., freshwater Cichlidae in Cameroon. The new genus is distinguished from other urin ary bladder monogeneans and from all Dactylogyridea by the haptor with 2 unequal ventral hooks, a single ventral transverse bar, and 14 vent ral marginal hooklets, and by a vas deferens loop around left intestin al branch as well as by a male copulatory apparatus with two accessory pieces in a claw shape. This new genus is proposed as the type of a n ew family, Urogyridae, and its systematic position is discussed.
