Description

GENUS BATHYPHOTIS STEPHENSEN, 1944

Bathyphotis Stephensen, 1944: 25.

Pseudischyrocerus – Bellan-Santini & Ledoyer, 1986: 397 (partim) (not Schellenberg, 1931).

Type species

Bathyphotis tridentata Stephensen, 1944.

Diagnosis

Antenna 1 subequal to antenna 2; peduncular article 1 long and rectangular; accessory flagellum with between three and six articles. Eyes present. Mandibular palp well developed and 3-articulate. Gnathopod 1 carpus shorter than propodus. Gnathopod 2 male subchelate; carpus longer than propodus. Coxae 1–4 longer than wide and coxae 5–7 wider than long. Coxa 4 posterior margin excavated. Coxa 5 with posterodorsal lobe absent. Pereopods 3 and 4 with merus equal in size. Pereopods 5–7 dactylus distal part (at least the propodus and dactylus) directed anteriorly; dactylus without accessory spines. Pereopod 5 carpus expanded, longer than propodus, without denticles or spines on a posteroventral margin. Pleosomite without lateral ridges. Pleopods peduncle slender and not expanded. Urosomite 1 with dorsal spines.

Included species

Bathyphotis crenatipes comb. nov. (Bellan-Santini & Ledoyer, 1986) and B. tridentata Stephensen, 1944.

Remarks

The cladistic analysis showed that Bathyphotis and Myersius gen. nov. are sister groups (clade 14), sharing the posterior margin of coxa 4 excavated and coxae 1–4 longer than wide as synapomorphies. Bathyphotis can be distinguished from Myersius gen. nov. by urosomite 1 with two dorsal teeth, outer ramus of uropod 3 with a recurved and weakly dentate tip, and telson without subapical spines.

Geographic distribution

Arctic Ocean; Atlantic Ocean, west of Cape Point, South Africa; Prince Edward Island, subantarctic region.
