Paramblyops – Birstein & Tchindonova 1970 (partim): 288 (upon species description).

Type species

Paramblyops globorostris Birstein & Tchindonova, 1970 View in CoL by present designation. This species was recorded by Birstein & Tchindonova (1970) from the NE Pacific, Kurile-Kamchatka Trench, 44°17ʹ N, 149°33ʹ E, depth 4690–4720 m. It is here transferred to the new genus as Chelamblyops globorostris ( Birstein & Tchindonova, 1970) comb. nov.

Diagnosis

Based in modified form on description of two adult females by Birstein & Tchindonova (1970). Eyes not connected, set apart, slender, roughly conical with weakly converging proximal and median portions, each distally strongly converging to an acute mid-apical process. Eyes all along densely packed with visual elements (lacking pigment), no ocular papilla. Antennular trunk with three segments separated by transverse articulations. Antennal scale not subdivided, its bare lateral margin ending in single, strong apical tooth; mesial margin setose all along. Antennal peduncle with three segments lined in a single plane. Labrum with spiniform mid-rostral process. Thoracomeres and pleomeres normal. Thoracic endopod 2 subchelate by dactylus inserting on disto-lateral edge of propodus; from there dactylus mesially bent and reflexed, opposing rugged and setose disto-mesial margin of propodus. Thoracic endopod 8 with carpus separated from 2-segmented propodus by oblique articulation. Both rami of uropods unsegmented, setose all around. Lateral margins of telson basally with small stand-alone spine, at some distance followed by series of less distantly set spines (distal portions of telson unknown).

Etymology

The genus name is a noun with Greek masculine ending, formed by amalgamation of the Greek noun ‘χηλή’ (‘pincers’) with the generic name Amblyops , related to the subchelate thoracic endopod 2.
