Morphology and speciation of Hawaiian and eastern Pacific Smittinidae (Bryozoa, Ectoprocta). Bulletin of the AMNH ; v. 152, article 6

Abstract

"Smittinidae (Bryozoa, Ectoprocta) from Hawaiian waters are compared with related species from the Galapagos Islands, Gulf of California, central and southern California in the eastern Pacific. Twenty-eight taxa are recognized, as follows: Hemismittoidea corallinea, new genus, new species; H. osburni, new species; Pleurocodonellina lahainae, new genus, new species; Smittoidea pacifica, new species; Smittina kukuiula, new species; one species of Codonellina and 22 species of Parasmittina, 15 of which are new. Scanning electron microscopy revealed many morphological and developmental details distinguishing the species and higher taxa. Distribution records in Hawaiian waters show isolation not only at the specific level from the Indo-Pacific and coastal eastern Pacific but also inter-island isolation due to unknown environmental factors"--P. 369.
