Description

Caeconyx Barnard & Karaman, 1991

(Fig. 3)

Caeconyx Barnard & Karaman, 1991: 473.

Type species. Hoplonyx caeculus Sars, 1891, original designation.

Included species. Caeconynx includes one species: C. caeculus (Sars, 1891).

Diagnostic description. Antenna 1 peduncle article 1 without anterodistal lobe; accessory flagellum forming cap covering callynophore. Antenna 2 without brush setae. Mandible molar setose with vestigial triturating surface. Maxilla 1 outer plate a well developed 7/4 crown. Maxilla 2 inner plate slightly shorter than outer plate. Gnathopod 1 subchelate; coxa 1 large, about as long as coxa 2, subrectangular with straight anterior margin ; ischium short (length less than 2 × breadth); carpus long (length 2 to 4 × breadth); propodus margins subparallel. Uropod 2 inner ramus not constricted. Telson deeply cleft.

Remarks. Caeconyx has no distinctive generic level characters. It appears to be similar to Anonyx. It differs from Anonyx in the mandibular palp which is attached midway in Anonyx (attached distally in Caeconyx) and the margins of the gnathopod 1 propodus which are tapering in Anonyx.

Distribution. North-eastern Atlantic Ocean. Iceland to Trondheimsfjord.
