Cedrosella Barnard & Karaman, 1987

Cedrosella Barnard & Karaman, 1987: 865 .— Barnard & Karaman, 1991: 474.

Type species. Ambasiopsis fomes J.L. Barnard, 1967, original designation by Barnard & Karaman, 1987: 865.

I ncluded species. Cedrosella contains two species: C. fomes (J.L. Barnard, 1967); C. cito sp. nov.

Diagnostic description. Antenna 1 accessory flagellum not forming operculum. Mandibular molar a reduced column, proximally setose, distally triturating; palp attached slightly distally. Maxilliped outer plate apical robust setae present. Gnathopod 1 subchelate; coxa large, slightly shorter than gnathopod 2 coxa, tapering distally; carpus distinctly shorter than propodus. Uropod 2 inner ramus not constricted. Telson deeply cleft.

Remarks. Cedrosella is similar to Ambasiopsis, differing from it in the lack of a carina on antenna 1 peduncle article 1, the arrangement of the setal-teeth (modified 6/ 5 in Cedrosella and reduced to seven setal-teeth in Ambasiopsis) and the length of the gnathopod 1 carpus (shorter than propodus in Cedrosella, longer than the propodus in Ambasiopsis). This is the first record of this genus outside of the Cedros Trench, off Baja California, a considerable increase to its Pacific Ocean distribution. Cedrosella appears to have a lower bathyal to abyssal depth range (1840–3745 m).
