Colossendeis geoffroyi Mañé-Garzón, 1944 View in CoL

Distribution: Rio Grande do Sul ( Brazil, 33°50´S– 51°51´W, 65 m) to northern Argentine shelf (down to 40°S) ( Mañé-Garzón 1944; Stock 1966, 1992; Larramendy 1974).

Uruguayan records: Mañé-Garzón (1944): 36°05´S– 53°03´W, 130 m depth (type locality).

Remarks: Stock (1966) reported many specimens of C. geoffroyi collected by the RV Calypso 1961 –1962 cruise station 172. Due to the mixing of materials, he reported specimens belonging to this species collected in one or more of six additional stations from that cruise (105, 149, 160, 161, 171 and 173) between Rio de Janeiro, Brazil and Buenos Aires Province, Argentina.

Larramendy (1974) identified 18 specimens from Argentinean waters (37°23´S– 40°01´S) collected by the RV Walther Herwig (1966–1971) as C. geoffroyi . He indicated that these do not differ from the original description, but complemented the description with additional details.

Stock (1992) reported one fragmented specimen from the coast of Rio de Janeiro (23°25´S– 43°00´W, 113 m depth), that he assigned with doubts to C. geoffroyi . He commented that “if…really this species, the range would be considerably extended in northward direction”.

Stock (1992) stated that the material reported by Minnard & Zamponi (1984) as C. geoffroyi seems to belong to a different species, given the differences illustrated by the Argentinean authors: “tarsus is [illustrated as being] almost twice as long as propodus; in C. geoffroyi both parts are almost equal in length”. Moreover, the data associated with that material is dubious. The RV Walther Herwig station 340 (cruise 1966) is not at 200 m depth, as reported by Minnard & Zamponi (1984), but 165 m depth; furthermore it is not located off Mar del Plata, as indicated by Stock (1992), but instead is off southern Argentina (53°57´S– 58°46´W).

López de Levy (1989) gave a general description of females attributed to C. geoffroyi mañé-garzón, 1944, obtained as by-catch in the commercial fishery off the La Plata River (Uruguay-Argentina, 35°–39°S) (López de Levy, pers. comm. to FS 2005).
