Genus Cancrion Giard & Bonnier, 1887 View in CoL

Type species: Cancrion miser Giard & Bonnier, 1887 View in CoL ; subsequent designation by McDermott et al. (2019).

Diagnosis. Female with dorsal ovarian processes, ventral processes lacking; second pair of oostegites covering basal part of first pair. Pleural lamellae on pleomeres 1 and 2 complex, complex or simple in pleomeres 3 and 4. Pleon of male without ventromedial spines. Pereopod 6 of epicaridium larva much longer than other pereopods, distodorsal margin of propodus with well-developed flange-like process. Cryptoniscus larva with 7 pairs of isomorphic pereopods.

Remarks. As discussed more in the Remarks section for the new species, the genus Cancrion is possibly paraphyletic; not all life history stages are known for all species and no larval stages are known for the type species. The diagnosis given above applies to most of the species for which larval stages are known.
