The Tropical Western Atlantic Perophoridae (Ascidiacea): I. The Genus Perophora
Abstract:Five species in the genus Perophora occur in the tropical western Atlantic, distinguished by morphology and habitat requirements. P. viridis and P. regina have four rows of stigmata and longitudinally oriented mantle muscles; P. multiclathrata, P. bermudensis and P. carpenteria n. sp. have five rows of stigmata and transversely oriented mantle muscles. Specific differences in the arrangement of the mantle muscles are considered to be of taxonomic importance. P. bermudensis is considered to be a valid species and not a synonym of P. multiclathrata. In the absence of a designated Type an original specimen of P. bermudensis from the type locality is declared to be the Neotype. P. viridis is the most cosmopolitan of Caribbean species while P. regina and P. bermudensis are restricted to areas of fairly strong flowing currents in mangrove channels. P. multiclathrata is characteristic of quiet sheltered environments and P. carpenteria flourishes in shallow water with moderately agitated water flow.
