Hydroides deleoni .— Salazar-Vallejo & Londoño-Mesa 2004: 54 (Tropical Eastern Pacific, checklist); Bastida-Zavala 2008: 25, fig. 6F (mentioned only); Bastida-Zavala 2009: 538, Fig. 2 B (identification key for Tropical America); ten Hove & Kupriyanova 2009: 53 (worldwide serpulid checklist).

Material examined. 20 specimens.

Baja California Sur: UMAR-Poly 755 (La Paz Bay, approx. 24°16’10”N, 110º19’29”W, SEAL-UABCS, PVC plate, one month in water, covered 85–90% by serpulids, mostly H. elegans , May 24, 1991, coll. Luis Varela).

Guerrero: UMAR-Poly 756 (16º50’N, 99º54’W, Cantiles, La Quebrada, Acapulco, on rock oyster, 8 m, May 26, 2000, coll. AM).

Oaxaca: UMAR-POLY 757 (Puerto Ángel, pier and beach, May 20, 2007, coll. FCC & SRH); UMAR-POLY 758, 2 spec. (Panteón Beach, Puerto Ángel, rocks, intertidal, June 12, 2012, coll. ERR & MJC).

Panamá: UMAR-POLY 759 (Yachting Club, Balboa, June 1, 2002, coll. SSV).

Perú: UMAR-Poly 760, 6 spec. (5°84’59”S, 80°94'21"O, Vichayo, Sechura, on shells of Argopecten purpuratus [ Lamarck ], 8 m, coll. IC); UMAR-Poly 761, 8 spec. (3°38'13"S, 80°35'22"O, Puerto La Cruz, Tumbes, 8 m, coll. IC).

Habitat. Intertidal to subtidal (35 m, Bastida-Zavala & ten Hove 2003). On PVC plate, rock oyster, on shells of Argopecten purpuratus , and one specimen found on a pier (Puerto Ángel, Oaxaca). Also in rock-pools and on a PVC structure surrounded by soft-bottom, with salinity range of 25–37 PSU (Bastida-Zavala & ten Hove 2003).

Distribution. Tropical Eastern Pacific. Baja California Sur ( México) to Ecuador (Bastida-Zavala & ten Hove 2003) and Perú.

Remarks. Hydroides deleoni was not commonly found on anthropogenic substrates; here we only report one specimen from a PVC plate (La Paz Bay) and another from a pier (Puerto Ángel); however, the species has a wide salinity range of 25–37 PSU (Bastida-Zavala & ten Hove 2003).
