Material examined.

(181 specimens) Baja California Sur: La Paz Bay, Magdalena Bay [24°38'09"N, 112°80'73"W] (139 specimens), December 6 1996, Coll. JALG; Sonora: Guaymas Bay (UANL 5238), Stn. 2 [27°53'28"N, 110°54'14"W] (18 specimens), May 6 1999; (UANL 5241), Stn. 6 [27°55'09"N, 110°52'39"W] (4 specimens), May 4 1999; (UANL 5242), Stn. 3 [27°54'13"N, 110°53'59"W] (2 specimens), May 6 1999; (UANL 5244), Stn. 1 [27°55'21"N, 110°53'14"W] (1 specimen), May 6 1999; Río Escondido [27°54'04.2"N, 110°54'08.2"W] (17 specimens), August 9 2006, 0.50 m, Coll. JALG.

Records.

This species has been reported to be broadly distributed around the world: Greenland ( Blake 2009), France ( Fauvel 1927), Southern Africa ( Day 1967), USA, California ( Hartman 1969, Blake et al. 2000), Costa Rica ( Dean 2001, 2004), Western México ( Reish 1963, 1968, Bastida-Zavala 1993). Blake (2009) indicates that Capitella capitata is probably only distributed in Arctic and subarctic areas and those numerous records from lower latitudes are probably not this species.

Remarks.

The specimens revised in this work from Western México are similar morphologically to the neotype of Capitella capitata redescribed by Blake (2009). The type locality (Greenland) of this species could indicates that records from warmer waters must be considered doubtful so that molecular studies may be required to separate them from the true " Capitella capitata " populations.
