ALVINOCARIS LUSCA WILLIAMS & CHACE, 1982

Type locality: eastern Pacific Ocean, Galapagos Rift, Rose Garden area ; 0°48.25′N, 86°13.48′W; 2450 m .

Known range: Known from the Galapagos Rift and the 9°N and 13°N vent fields of the EPR, at depths of 2450–2600 m ( Shank, 1997, in Desbruyères & Segonzac, 1997).

Material: type locality; Alvin dive 990; 9 December 1979; USNM 184534 (holotype, male), USNM 184535 (allotype, female), USNM 184537 (paratype male), USNM 184536 (paratypes, 11 females), USNM 184538 (1 juvenile) ( Williams & Chace, 1982) .

– Galapagos Rift, 00°48.2′N, 86°13.4′W; Alvin dive 2224; 2461 m; 29 May 1990. Non-type: 2 specimens, sex not listed ( Shank et al., 1999) .

– EPR, 9°N site , 09°50.3′N, 104°17.4′W; Alvin dive 2692; 2520 m; 26 December 1993; non-type, 2 specimens, sex not listed ( Shank et al., 1999).

Williams & Chace (1982) noted that 1 paratype female would be transferred to each of the following collections: MCZ, AHF / LACM, BMNH, RMNH, MNHN .

Remarks: This is the only species of Alvinocaris reported from the eastern Pacific to date. Hessler & Smithey (1983) provided brief observations on ecology and behaviour of the species at the Rose Garden site. Van Dover (1986) examined stable isotope ratios and compared them with another vent decapod (the galatheid Munidopsis subsquamosa ). Van Dover et al. (1985) described planktotrophic larval development. Shank (1997, in Desbruyères & Segonzac, 1997) provides limited ecological observations on its ecology and feeding. Fustec, Desbruyères & Juniper (1987) noted the species from the 13°N site on the EPR, but the specimens that they observed might have been Lebbeus ( T. Komai, pers. comm.). Shank et al. (1999: 251) listed A. lusca from the site at 13°N but did not provide any information on that record.
