Pleurochorium annandalei Schrammen, 1912, known previously from the N Indian ocean, is found to be widely distributed in the W Indian ocean as well. Two new subspecies of P. annandalei are described. A finding of a more complete, branching specimen and examination of its spicule content showed that Pleurochorium has much more complex body form then was previously considered. The type of tubular branching observed in this genus may not be attributed to dichotomous or to any of its variations but it should be considered as a regular emission of tubular branches from the side of the wall. Hence the genus should be conserved within Chonelasmatinae. The new data allow supplementation of the diagnosis of this genus and clarify the differences between the subfamilies of Euretidae.
