Stephanotheca Reverter-Gil, Souto & Fernández-Pulpeiro, 2012


Genus Stephanotheca Reverter-Gil, Souto & Fernández-Pulpeiro, 2012 View in CoL

Type species. Stephanotheca barrosoi Reverter-Gil, Souto & Fernández-Pulpeiro, 2012 , by original designation.

Remarks. Reverter-Gil et al. (2012) provisionally placed Stephanotheca in the Lanceoporidae , recognising that the genus shares characters with both the Lanceoporidae and the Bitectiporidae . It shares cleithral ovicells, orifice dimorphism, vicarious avicularia and cormidial secondary calcification with the Lanceoporidae , and the crowned ooecium with Hippoporina and Schizomavella (Bitectiporidae) .

All nine temperate species of Stephanotheca described by Reverter-Gil et al. (2012) have a single, medial, proximally directed adventitious avicularium (sometimes wanting in some species). The two tropical species described here differ in having more than one avicularium on some zooids. In addition, S. romajoyae n. sp. is unique in having dimorphic avicularia (small and very large forms, the latter occupying most of the frontal shield), sometimes occurring on the same zooid.
