gen. nov.

Jodoella n. gen.

Type species. Jodoella koreensis n. sp.

Etymology. Alluding to the provenance of the genus at Jodo Island, Korean South Sea.

Remarks. A new genus is established here for a species of Robertsonidridae that has dimorphic orifices, enlarged ooecia and avicularia with a rounded rostrum. Like the genus Robertsonidra Osburn, 1952 , Jodoella n. gen. has a non-pseudoporous granular-tubercular frontal shield, a pseudoporous granular-tubercular ooecium, a rounded orificial sinus and an avicularium with a cross-bar. Rosso in Rosso et al. (2010) established the new family Robertsonidridae to accommodate this combination of characters but allowed inclusion of her monotypic new genus Bertorsonidra , which shares this suite of morphologies except for frontal-shield pseudopores that are not densely distributed. Like the type species of Robertsonidra , Bertorsonidra also has short prop-like supports elevating the colony just above the substratum, but these structures are lacking in Jodoella n. gen. Rosso et al. (2010) interpreted the ooecium as comprising a pseudoporous calcified endooecium and a membranous ectooecium that is continuous with the distal autozooidal epitheca, i.e. microporelliform in the terminology of Ostrovsky (2013). Superficially, Jodoella resembles Powellitheca Di Martino, Taylor, Gordon & Liow, 2016 , an endemic New Zealand genus that also has dimorphic orifices and large microporelliform ooecia, but differs in having a pseudoporous frontal shield, convex proximal rim, small orificial condyles and avicularia lacking a crossbar.
