MUNIDOPSIS ALVISCA WILLIAMS, 1988

Type locality: eastern Pacific Ocean, Gulf of California, Guaymas Basin ; 27°00′N, 111°25′W; 2008 m GoogleMaps .

Known range: Known only from the periphery of hydrothermal vent fields on the Explorer and Juan de Fuca ridges at 1545–1800 m in the North Pacific ( Williams, 1988) and in the Guaymas Basin (Gulf of California) at 2000 m ( Williams, 1988; Khodkina, 1991; Chevaldonné & Olu, 1996; Van Dover, 1997, in Desbruyères & Segonzac, 1997).

–north-eastern Pacific Ocean, Juan de Fuca Ridge, Limbo Vent, 3 m from Holland’s Hillock Axial Seamount; 45°55′N, 130°03′W; 1545 m; ASHES Expedition, Pisces IV dive P-1732; 2 August 1986 ; USNM 234299 View Materials (paratypes, 2 ovigerous females) ( Williams, 1988) .

– Gulf of California, Guaymas Basin; 27°02′79″N, 111°22′80″W; 1987 m; Expedition 12, R / V Academician Mstislav Keldysh, Pisces IV sta. 1534; non-types, 1 male, 1 ovigerous female. −27°02′70″N, 111°24′50″W; 1967 m; Expedition 12, R / V Academician Mstislav Keldysh; Pisces IV sta. 1575; non-type, 1 ovigerous female ( Khodkina, 1991).

Remarks: Collections of this species from the Guaymas Basin include the holotype and a paratype female, as well as three specimens noted by Khodkina (1991) found on the slope of a smoker among colonies of Riftia . The species, or a similar one, has been observed but not collected at several other vent sites along the Juan de Fuca ridge apart from sites listed above. Chevaldonné & Olu (1996) noted the possibility that the galatheid reported by Van Dover, Grassle & Boudrias (1990) from vents of the Escanaba Trough on the Gorda Ridge might also be M. alvisca . Van Dover (1997: 201, in Desbruyères & Segonzac, 1997) gives anatomical characters that distinguish the species from the morphologically similar Munidopsis subsquamosa (which is possibly a species complex; see below under Munidopsis subsquamosa ).
