Abstract

A new mysid genus and species, Stellamblyops vassilenkoae gen. nov., sp. nov., is described. It is the seventh genus of the tribe Amblyopsini. Stellamblyops gen. nov. is characterized by the form of eyes, which are flattened laterally, tear-shaped plates with very long, pointed frontal processus, the uropodal endopod without spines in the statocyst region and the form of the telson, which is elongated, linguiform with minimal width on the distal third, the telson apex with small cleft, whose margins have small spines, distal three-quarters of the lateral margins of the telson with larger spines. All specimens of this species were collected with help of a camera-epibenthic sledge during two deep-sea Russian-German expeditions in the Kuril-Kamchatka Trench and its adjacent waters: KuramBio expedition (Kurile Kamchatka Biodiversity Studies) and SokhoBio expedition (Sea of Okhotsk Biodiversity Studies): holotype: 1>, length 13.2 mm, 23.08.2012, RV Sonne, KuramBio expedition, st. 09-9, depth: 5399–5408 m, 40°35.48?N; 150°59.92?E – 40°34.25?N; 150°59.91?E; non-type specimens: 1+, length approximately 9.1 mm, 17.08.2012, RV Sonne, KuramBio expedition, st. 07-9, depth: 5216–5223 m, 43°02.84?N; 152°59.43?E – 43°01.49?N; 152°58.36?E; 1juv., length 6.0 mm, 30.07.2012, RV Sonne, KuramBio expedition, st. 01-10, depth: 5418–5429 m, 43°58.26?N; 157°19.67?E – 43°58.33?N; 157°17.97?E; and 1>, length approximately 18.5 mm, 26.07.2015, RV Akademik M.A. Lavrentiev, SokhoBio expedition, st. 09-7, depth: 3371–3377 m, 46°16.16?N; 152°03.10?E – 46°16.07?N; 152°03.32?E.
