Genus Calyptotheca Harmer, 1957

Type species. Schizoporella nivea var. wasinensis Waters, 1913 , by original designation ( Harmer 1957, p. 1008).

Remarks. A revised diagnosis of Calyptotheca was recently given by Cumming & Tilbrook (2014). Key features of the genus are: (1) lepraliomorph frontal shield densely and evenly covered by pseudopores; (2) primary orifice with a proximal sinus and proximolateral condyles; (3) absence of orificial spines; (4) globose, pseudoporous ovicells with calcification resembling the frontal shield of the distal zooids on which they rest; and (5) adventitious avicularia located suborally, latero-orally, or marginally. The genus contains at least 57 living species ( Bock et al. 2017, accessed 11 April 2017) and has a fossil record dating back to the Oligocene ( Guha & Gopikrishna 2007).
