Abstract
Three groups of cheilostome bryozoan species, formerly classified in the genus Electra Lamouroux, and possessing branching spines – the feature strictly discriminating them from all other electrids, are placed in three new genera based on unique combinations of features of spines, cryptocysts, and opercula: Osburnea gen. nov. is established for the Electa biscuta Osburn; Arbocuspis gen. nov. for Electra bellula (Hincks), and Arbopercula gen. nov. for Electra bengalensis (Stolizcka).
