Lebbeus wera Ahyong, 2009

Lebbeus wera Ahyong, 2009: 786 , figs 5–7 (type locality: Brothers Caldera, Kermadec Ridge); 2010: 346, fig. 3B.— Komai et al. 2012: 41 View Cited Treatment , fig. 5.

Material examined. DS “Nautile”, dive 1774, Kulo Lasi, Futuna, 14°56.5472’S, 177°15.0061’W, 1418 m, 11 September 2010, slurp gun, bottle 4, 1 female (cl 12.9 mm; infested by rhizocephalan), MNHN-IU- 2011-2510; same data, 1 female (cl 6.9 mm), MNHN-IU-2011-5016; dive 1776, same site, 14°56.3514’S, 177°15.5777’E, 1406 m, 13 September 2010, slurp gun, bottle 4, 1 male (cl 10.0 mm), MNHN-IU-2011-3920; same data, bottle 3, 1 male (cl 10.6 mm), MNHN-IU-2011-5034; same data, bottle 4, 3 juveniles, MNHN-IU-2011-5061; dive 1777, same site, 14°56.5574’S, 177°15.0001’W, 1477 m, 13 September 2010, slurp gun, bottle 3, 1 female (cl 9.2 mm; infested by bopyrid), MNHN-IU-2011-5072.

Distribution. Previously known only from the Brothers Caldera in the Kermadec Arc, New Zealand, at depths of 1208–1336 m. The present material extends the geographical range of this species to the north and the bathymetric range to the depth of 1477 m.

Remarks. The present adult specimens agree well with the original description and subsequent accounts of L. wera (cf. Ahyong 2009, 2010; Komai et al. 2012) in every diagnostic aspect. In particular, L. wera is characteristic among the species of the genus occurring in chemosynthetic communities in having relatively more numerous postrostral teeth on the carapace (four or five versus three or less). Lebbeus shinkaiae has three to four postrostral teeth, but the supraorbital tooth in a rostral position will immediately differentiate L. shinkaiae from L. wera .

Lebbeus wera , like Alvinocaris komaii , was found to be associated with the bush of the siboglinid tube worm Arcovestia ivanovi , but also occurs on rocky areas adjacent to vents together with a squat lobster Munidopsis lauensis Baba & de Saint Laurent, 1992 ( Fig. 6 View FIGURE 6. A B).
