Hydroides ochoterenai .— Salazar-Vallejo & Londoño-Mesa 2004: 54 (Tropical Eastern Pacific, checklist); Bastida-Zavala 2009: 534, Figs 2 Q, 5H (identification key for Tropical America); Bastida-Zavala et al. 2013: 349 (Oaxaca, checklist). Sensu auctore misspelling, see Remarks.

Material examined. Two specimens.

Guerrero: UMAR-Poly 772 (17°37’10.58”N, 101°31’27.23”W, Zihuatanejo, Manzanillo, Tlacoyunque, sta. 3, on coral Pocillopora damicornis , 3 m, December 4, 2010, coll. SGG).

Oaxaca: UMAR-POLY 773 (Chacahua Lagoon, on rock, April 3, 2008);

Habitat. Intertidal to subtidal (10 m, Bastida-Zavala & ten Hove 2003). On coral Pocillopora damicornis . Also in rock pools, on rocks and bivalve shells (Bastida-Zavala & ten Hove 2003; Bastida-Zavala 2008).

Distribution. Tropical Eastern Pacific. From Manzanillo, Guerrero to Colombia and Galápagos Islands (Bastida-Zavala & ten Hove 2003).

Remarks. Bastida-Zavala & ten Hove (2003) corrected the specific name from ochotereana to ochoterena , because Rioja (1941a: 167) dedicated the species to Ignacio Ochoterena , a masculine noun; however, as it was the author who was responsible for an incorrect latinisation (ICZN 1999: Art. 32.5.1) his original spelling should not corrected.

Hydroides ochotereana is rare except in Acapulco, Guerrero, and Galápagos Islands, where several specimens were found. With this new record its known geographical range is extended from Manzanillo Point, in Acapulco area (Bastida-Zavala & ten Hove 2003) to Manzanillo, in Zihuatanejo area, both located in Guerrero, along the littoral approximately 200 km to the north.
