GENUS LEBBEUS WHITE, 1847

Although species have been reported from several hydrothermal vent sites, members of the genus Lebbeus are almost certainly vagrants rather than endemics, as they occur in other areas of the deep sea; indeed, Lebbeus is one of the more widely occurring genera of deep sea hippolytid shrimp (M. Wicksten, pers. comm., see also Wicksten, 1978, 1982; Wicksten & Méndez, 1982; Hayashi, 1992; Fransen, 1997; Komai, 2001). Most of the known species are found in the northern Pacific Ocean (Wicksten, 1982; Hayashi, 1992). Species of Lebbeus have been observed along with Alvinocaris shrimps and have been attracted to baited traps on the Iheya Ridge of the Mid-Okinawa Trough ( Kim & Ohta, 1991: fig. 7, 2); shrimps of the genus Lebbeus also have been collected from baited traps near vents in the eastern Pacific (T. Shank, unpubl. data; see below under L. bidentatus ). Two described species of Lebbeus have been reported from vents in the Pacific ( Desbruyères & Segonzac, 1997: 197–198). The species reported as Lebbeus sp. by Ohta (1990a: fig. 7) from the Iheya Ridge was later identified as Lebbeus washingtonianus by Kikuchi & Ohta (1995) (see below). Fujikura et al. (1999, table) listed Lebbeus sp. at Sagami Bay seeps. Fransen (1997) redescribed in detail all three species described originally by Zarenkov – L. bidentatus , L. carinatus and L. curvirostris – based on the original type material. There is also a catalogued specimen of Lebbeus (though currently unnamed) at the Field Museum (FMNH 11289) that was collected on DSMV Alvin dive 3940 at Caldera, an off-axis site (approximately 1.5 km off axis) in the EPR where these is considerable hydrothermal activity (J. Voight, pers. comm.).

Lebbeus sp. A . The unidentified species of Lebbeus reported from the Lau Basin by Desbruyères et al. (1994) is referred to in Table 1 as Lebbeus sp. A .

Lebbeus sp. B . The species of Lebbeus from Sagami Bay reported by Fujikura et al. (1999) is listed in Table 1 as Lebbeus sp. B .
