ABSTRACT
We establish the new podocerid genus Capropodocerus gen. nov. for the two new species Capropodocerus tagamaru gen. et sp. nov. (collected from 775800 m depth in the Kumano Sea, Japan) and Capropodocerus kamaitachi gen. et sp. nov. (collected from 840873 m depth off the eastern coast of Miyagi, Japan). Capropodocerus shares elongate pereonites 13 with Neoxenodice but differs from the latter in lacking uropod 2 and in having pereonite 3 at least twice as long as pereonite 4. Capropodocerus is also similar to Laetmatophilus and Leipsuropus in having only two pairs of uropods but differs from them in having i) pereonite 1 longer than the head and ii) pereonite 3 at least twice as long as pereonite 4; Capropodocerus has three urosomes and Laetmatophilus has two urosomes. The two species in Capropodocerus differ in i) the length ratio of the antenna 1 peduncle to the flagellum, ii) the shape of the gnathopod 2 palm, iii) the presence or absence of a mid-posterior triangular projection on the gnathopod 2 dactylus, and iv) the length ratio of the basis to the merus of pereopod 3. A key to all genera in Podoceridae is provided.
