Material examined. 18 specimens.

Baja California Sur: UANL 7898, 8 spec. ( Puerto Escondido , sta. 2: 25°48’53.1”N, 111°18’40.5”W, April 2, 2011, coll. JAL & ARB)GoogleMaps  ; UANL 7899View Materials ( Puerto Escondido , sta. 3: 25°48’51.7”N, 111°18’41.2”W, April 2, 2011, coll.

Oaxaca: UMAR-POLY 807, 8 spec. (Puerto Ángel, pier, May 20, 2007, coll. FCC & SRH); UMAR-POLY 808, 3 spec. (La India Beach, Huatulco, on Spondylus calcifer  [now S. limbatus  ], December 3, 2005, coll. JHB); UMAR-POLY 809 (Conejos Bay, Huatulco, June 11, 2005, coll. JHB & GNL).

Habitat. Intertidal to subtidal (17 m, Bastida-Zavala 1995). Most specimens revised here were from anthropogenic substrates in marinas and ports (from La Paz and Puerto Escondido, Baja California Sur, and from Puerto Ángel, Oaxaca). However, previously it was found on live ( Porites lobata  ) and dead coral ( Pocillopora verrucosa  ), on spiny oyster Spondylus limbatus  and Pinctada  , on rock pools, and on pier piles (Bastida-Zavala 2008). Fouling species.

Distribution. Tropical Eastern Pacific. Baja California Sur ( México) to Panamá and Colombia (Krøyer [in] Mörch 1863; Ehlers 1887; ten Hove 1970; Bastida-Zavala 1995).

Remarks. Spirobranchus incrassatus  was found both in natural and anthropogenic substrates. It is a fouling species with the potential to be introduced to other tropical regions by ships. The species was confused several times with S. giganteus  , a Caribbean species (see remarks in Bastida-Zavala 2008).

Hernández-Alcántara et al. (2003: 9) list Treadwell’s (1914) record of Spirobranchus quadricornis ( Grube, 1878)  from Santa Catalina Island, Baja California Sur; however, this is a mistake, the record of Treadwell (1914) corresponds to Avalon, in Santa Catalina Island, Southern California, and the material most likely belongs to S. spinosus  .
