Stenorhynchus yangi - Goeke, 1989: 630, Barbados. - Poupin, 1994: 45, Guadeloupe [R/V Polka, 170-450 m, det. J. Poupin (MNHN), with a doubt for the station number]. - Carmona-Suárez & Poupin, 2016: 367, Guadeloupe, Karubenthos 2012, 2 spp. MNHN- IU-2014-12828 (lots JL314, JL315), st. GN11, 140 m; 1 sp. MNHN-IU-2014-12829 (lot JL1384), st. GD58, 95 m; 1 sp. MNHN-IU-2013-6629 (lot JL340), st. GN09, 140 m; 1 sp. MNHN-IU-2013-4065 (lot JL313), st. GN07, 150 m. - Poupin & Corbari, 2016: in press, Guadeloupe, Karubenthos II 2015, st. DW4586, 21 June 2015, 15°59.62'N, 61°22.51'W, 251-204 m, MNHN-IU-2013-18879.
Comment: Affiliated to Stenorhynchus seticornis. The two species can be tell apart by the aspect of the rostrum, with (S. seticornis) or without (S. yangi) setae at tip. Usually S. yangi is collected deeper than S. seticornis.
French Guiana and surroundings areas: Guiana, Suriname, Brazil (Amapà)
Stenorhynchus yangi Goeke, 1989: 632, table 2, Suriname [USNM 103269, 6°52'N, 54°53' W, 288 m].
Distribution/Habitat
WA; Marine (Suriname is the southern limit); 31–450 m.
Remark
The single specimens collected off Suriname seem to be those indicated by Goeke (1989, table 2, 2 spp., USNM 103269). In USNM collection, n° 103269 is currently attributed to S. seticornis, det. Holthuis, coll. R/V Coquette, st. 33, 12/05/1957, 6.87 N, -54.88 W, 51 m, instead of 288 m in Goeke (1989). An other specimen collected during the same R/V Coquette campaign, and determined by Holthuis, is listed by Goeke (1989) with S. seticornis (table 1, USNM 103268, st. 32, 51 m). This casts some doubt on the presence of S. yangi off Suriname, currently its southernmost WA limit. I will be interesting to confirmed it in the future.
