Family incertae cedis * Author Bird, Graham J text Zootaxa 2007 1599 121 149 journal article 10.5281/zenodo.178710 6dfc7d0a-e2a3-46b0-bd4c-856e8f515f61 1175-5326 178710 Chauliopleona spp. Material examined. 1 manca-III, station XR-12, 41º37.67’– 41º37.08’N 146º54.19’– 146º52.72’E , 5473– 5484 metres, 4 m ORE beam trawl, 23 September 2001 . 1 non-ovigerous female, station XR-5, 42°23.83’– 42°22.06’N 145°31.06’– 145°27.70’E , 3145–3265 metres, 16 September 2001 . 1 post-ovigerous female, station XR-7, 42°12.87’– 42°12.10’N 145°33.93’– 145°32.05’E , 3853–3858 metres, 17 September 2001 . Remarks. Only three specimens of Chauliopleona were obtained in the present study, two of them damaged (but not so far as to be totally unidentifiable) and one a small manca-III stage. Two species may be present: one from stations XR-12 (manca-III, length 1.72 mm ) and XR-5 (non-ovigerous female, length 3.8 mm ) and the other from XR-7 (post-ovigerous female, 4.9 mm ). The first has a weakly crenulated cheliped dactylus and, in the larger individual, a very long ventrally -directed pleonal spur. It also possesses a coarsely ornamented cuticle. The second putative species lacks cheliped crenulations, a posteriorly -directed pleonal spur, and has more slender pereopods and uropods. Both species have a relatively shallow cheliped carpal shield. Further study (and, ideally, additional specimens) is required to formally identify or name these taxa, although they do not easily match any described species.
