BYTHOGRAEA MICROPS DE SAINT LAURENT, 1984

Type locality: north-eastern Pacific Ocean, EPR; 21°N; 2615 m .

Known range: EPR, from vents at 9°50′N (2535 m) and 13°N (2620 m) and from the Galapagos Rift at 2450 m (Guinot, 1997, in Desbruyères & Segonzac, 1997) to 21°N. Guinot & Hurtado (2003: 437).

Material: type locality; Oasis, Alvin dive 1211; 17 April 1982; USNM 195002 (holotype female) ( de Saint Laurent, 1984) . – EPR; 12°48.85′N, 103°56.60′W; 2620 m; BIOCYATHERM, Nautile, dive 33; 8 March 1982 ; MNHN B107108 (allotype male) ( de Saint Laurent, 1984) .

– Totem hydrothermal site; 12°48.80′N, 103°56.45′W; 2640 m; MISSION HOT 96, Nautile, dive 29; 18 March 1996; MNHN-B 25393 (non-types, 1 male, 1 male juvenile, 2 female juveniles) ( Guinot & Segonzac, 1997) .

– Parigo hydrothermal site; 12°48.57′N, 103°56.41′W; 2648 m; MISSION HOT 96, Nautile, dive 26; 15 March 1996; MNHN-B 25394 (non-type, 1 juvenile) ( Guinot & Segonzac, 1997) .

– M-Vent hydrothermal site; 09°50.83′N, 104°17.57′W; 2535 m; MISSION HOT 96, Nautile, dive 22; 10 March 1996; MNHN-B 25395 (non-type, 1 juvenile male) ( Guinot & Segonzac, 1997) .

– EPR, 12– 13°N, Pogonord and Parigo vent sites, 10 small specimens from dives 32, 38 and 41 (MP- B12826, MP-B12828 and MP-B13000 ( Guinot, 1988).

Remarks: This is a small species (13 × 24 mm), and most of the known specimens are juveniles. De Saint Laurent (1988) briefly illustrated the megalopa and young crab stages. Guinot (1997, in Desbruyères & Segonzac, 1997) noted that the species came from Riftia and clam washings. Guinot & Hurtado (2003) compared the morphology of this species with others in the genus.
