Genus Bryoconversor gen. nov.

urn:lsid:zoobank.org:act:761AFF11-1BB8-4DFD-9126-E15D7C0B8ECB

Type species

Bryoconversor tutus sp. nov., by monotypy

Etymology

From prefix bryo - (abbreviation of bryozoan) and Latin conversor, to dwell with.

Diagnosis

Head lateral cephalic lobes weakly produced forward, subtriangular; anteroventral excavation weak. Eye present. Labrum lacking epistome. Antenna 1 & 2 subequal in length. Gnathopod 2 larger than gnathopod 1, subchelate; Pereopod 5-7 coxae very shallow. Epimera rounded; Urosome segments 1 and 2 coalesced. Uropods 1-2 biramous, inner ramus longer than peduncle, weakly curved with deep longitudinal ridges and completely lacking setae. Uropod 2 posterior margin with a strongly developed flange with a pitted edge. No sexual dimorphism.

Remarks

The new genus is very close to Chevalia Walker, 1904 , which also lacks sexual dimorphism, but it differs from the latter in the presence, on the posterior margin of the uropod 2 peduncle, of a greatly expanded flange with a pitted edge (whose function is unknown). In Chevalia , the uropod 2 peduncle is unexpanded. In addition, the uropod 1 inner ramus inner margin is smooth in Bryoconversor , but with a row of large serrate spines in Chevalia . It also differs by the deep longitudinal ridges on uropod 1 and 2 inner ramus that are clearly visible under the light microscope in Bryoconversor . These ridges cannot be seen in Chevalia under the light microscope, although confirmation of their absence with SEM would be advisable.
