ABSTRACT:

The genus Hydroides Gunnerus, 1768 is the most species rich serpulid genus with 89 valid species (ten Hove & Kupriyanova, 2009). The Hydroides species from the Western Atlantic and Eastern Pacific (including Hawaii) have been taxonomically revised by Bastida-Zavala & ten Hove (2002, 2003), but species from the most diverse region (Indo-Pacific) are still understudied. Most of the Hydroides are readily distinguished by opercula structures; otherwise they are very similar morphologically with exception of a few species with more than 7 thoracic chaetigers (i.e. Hydroides bisectus Imajima & ten Hove, 1989 and Hydroides sp. 2 sensu Bastida-Zavala & ten Hove, 2003). Hydroides perezi is the only Hydroides species previously recorded in checklists of Marshallese polychaetes (Bailey-Brock, 1999, 2003), but detailed description of this species in Guam is lacking. We provide descriptions and scanning electron microscopy (SEM) photographs of opercula and chaetae of H. perezi from Pago Bay in addition to two new records H. albicepsand H. bannerorum from Apra Harbor, Guam.
