Diagnosis

Carapace normal. Eyes stalked, set apart, lateral margins not produced in a finger-like non-sensory process; stalk with ocular papilla; visual elements incomplete. Appendix masculina well developed. Antennal peduncle with three segments in linear arrangement; lateral margin of scale being bare up to an apical tooth or (in D. latisquamosus ) only to a subapical tooth. Thoracomeres and pleomeres normal. Thoracic endopod 2 not prehensile, endopods 3–8 with unsegmented carpus separated from 1–2-segmented propodus by an oblique articulation. Female with three pairs of oostegites. Female pleopods reduced to uniramous setose plates. Male pleopods biramous, setose, no spines; endopod 1 unsegmented, endopods 2–5 and all exopods multi-segmented. Both rami of uropods unsegmented, setose all around; endopod with or without spine. Telson normal, no lateral constriction, no terminal incision, lateral margins not serrated; terminal and part of lateral margins with spines, no setae.

Type species

Dactylamblyops Hodgsoni Holt & Tattersall, 1906 View in CoL , by original designation according to ICZN (1999).

Revised combinations

Dactylamblyops laticauda Birstein & Tchindonova, 1958 View in CoL is here recombined as Amblyopsoides laticauda ( Birstein & Tchindonova, 1958) comb. nov. (see below). The binomen Dactylamblyops japonica Ii, 1964 is here acknowledged based on the species having an antennal scale with a bare lateral margin up to a large apical tooth. In contrast, the type species of Hyperamblyops Birstein & Tchindonova, 1958 View in CoL , i.e., H. nana Birstein & Tchindonova, 1958 View in CoL , shows an antennal scale with a setose outer margin not ending in a tooth. Accordingly, the recombination of D. japonica Ii, 1964 as H. japonica ( Ii, 1964) by Murano (1975) is not acknowledged here.

D. iii Nouvel & Lagardère, 1976 View in CoL from the NW Pacific: off Japan, 34– 35° N, 138– 140° E, depth 70–1300 m, ≤ 2000 m ( Ii 1964; Nouvel & Lagardère 1976; Murano 1981; Wittmann & Ariani 2019; Wittmann & Chevaldonné 2021)

D. murrayi W.M. Tattersall, 1939 View in CoL from the Arabian Sea and Weddell Sea, total range 35° N – 63° S, 28° W – 139° E, depth ≤ 480 to 4543 m (W.M. Tattersall 1939; San Vicente & Cartes 2011; Wittmann & Ariani 2019; Wittmann & Chevaldonné 2021; present paper: 7)

D. pellucidus Birstein & Tchindonova, 1958 from the NW Pacific: off Japan, Kuril-Kamchatka Trench, 30– 42° N, 137– 152° E, depth 4400–5140 m ( Birstein & Tchindonova 1958; Golovan et al. 2019). Specimens from about 1000 m off Japan reported by Murano (1981) as D. pellucida View in CoL are not acknowledged due to their having fewer (0–1 vs 4) spines on the endopod of the uropods and more (32 vs 25) spines on the lateral margins of the telson, compared to the original description
