Remarks. The new species described below ( E. turbulenta ) was initially identified as E. aff. annulosa (see Puillandre et al. 2011). However, E. annulosa is easily distinguished from E. turbulenta by the number of distal spines on the carpus of the P1 (chelipeds): two spines (mesial spine absent) in E. annulosa instead of three in E. turbulenta . Furthermore, the antennal peduncles are different (see Figs. 2E, F ). Antennal article 2 has the distolateral spine longer, nearly reaching the midlength of article 4 in E. turbulenta , rather than never reaching the midlength of article 4, as in E. annulosa ; antennal article 4 is more than 3.5 in E. turbulenta , instead of less than 2.5 times longer than broad in E. annulosa . Genetically, E. annulosa is very different from E. turbulenta , with genetic distances for COI and 28S: 7.8–8.1% and 8.5–9.0%, respectively ( Puillandre et al. 2011).

Distribution. New Caledonia and Chesterfield Islands, 230– 650 m. Present material from 315 to 1260 m.
