Remarks: This species is the only Alvinocaris known from any cold seep (although a second species is being described from the Blake Ridge Diapir; T. Komai, pers. comm.). Until recently, this species was known only from its type locality in the Gulf of Mexico. It is now known from South Barbados and from extensive collections made in the Gulf of Guinea ( Olu et al., 1996a; T. Komai, pers. comm.) and from the Blake Ridge Diapir ( T. Komai, pers. comm.).

A morphologically very similar shrimp (referred to as Alvinocaris cf. muricola ) was reported from the Blake Ridge seeps by Van Dover et al. (2003); that species is being described as new by Komai et al. (in press).
