Additional material

Five specimens: LACMNH N1908, 1 specimen (California, approx. 36°36' N, 121°53' W, Monterey Shale, dredged off Del Monte, 12–16 m, 3 Jun. 1934, coll. E.F. Ricketts, as Ditrupa sp.); LACMNH N1909, 2 specimens (California, approx. 37°12' N, 122°24' W, Moss Beach, Jul. 1933, as? Ditrupa ); LACMNH N1910, 2 specimens (California, approx. 37°12' N, 122°24' W, Moss Beach, 1934, as? Ditrupa ).

Diagnosis

Tube white, smooth; with a longitudinal ridge; without transverse ridges, peristomes or alveoli. Opercular peduncle smooth, white. Operculum white, spherical or conical ( Fig. 7F View Fig ). Collar with fin-and-blade chaetae ( Fig. 9N View Fig ).

Taxonomic remarks

Pseudochitinopoma occidentalis was the species with the largest distribution in the survey, with 12 localities in the northeastern Pacific, from Dutch Harbor, Alaska, to Morro Bay, California. It was also the second most common species represented on fouling plates; only Hydroides dianthus , a species from the U.S. east coast, was encountered more often ( Table 1 View Table 1 ). Despite its frequency on fouling plates, P. occidentalis has not been reported as NIS elsewhere.

Ecology

Intertidal to 229 m ( Hartman 1948; Zibrowius 1969a). Rocky bottoms, on tubes of Serpula columbiana , Crucigera zygophora , Vermiliopsis multiannulata , shells of the brachiopod Laqueus californianus , alcyonarians, solitary corals, tunicates, burrowing clams and PVC fouling plates ( Bush 1905; Bastida-Zavala 2008; Kupriyanova et al. 2012).

Distribution

Northeastern Pacific, from Alaska to Ensenada, west coast of Baja California Peninsula ( Kupriyanova et al. 2012). In this survey, Pseudochitinopoma occidentalis was abundantly and frequently on fouling plates from Dutch Harbor, Kachemak Bay, Kodiak and Sitka, Alaska, and Puget Sound, Washington; occasionally from Valdez Bay, Prince William Sound and Ketchikan, Alaska, Coos Bay, Oregon, Humboldt Bay, San Francisco Bay and Morro Bay, California ( Fig. 8 View Fig ).
