Plumularia roxanae, a new epiphytic hydroid (Cnidaria: Hydrozoa: Plumulariidae from the Indo-Pacific

摘要

A new epiphytic, small-sized species of Plumularia Lamarck, 1816, P. roxanae sp. nov., is described based on fertile material from Bali, Indonesia. Its deep hydrothecae are characteristically narrowed distally through a distinctive hypertrophy of the free portion of their adaxial wall. Its minute gonothecae, however, are comparable in shape and size to those of the well-known, circumtropical P. floridana Nutting, 1900.
