Type Specimen: Paratype; NMV ; Verified; Unknown
Type Locality: Recent: South Australia, 16-148 m
Type species well described by Cairns and Parker (1992: 39). Paratypes also deposited at SAM and USNM (see Stranks, 1993).
Corallum cylindrical, resulting from transverse division, the anthocyathus stage up to 11 mm in GCD; theca imperforate; finely granular, higher cycle costae originating by trifurcation; septa hexamerally arranged in 4 cycles; small multiple P1-3; columella rudimentary, granular.
Similar to Peponocyathus, but differs in having a rudimentary columella, and multiple paliform lobes per septum
This genus and family was monographed by Cairns (1997), which included a phylogenetic analysis based on morphology. Monotypic.
Recent: 16-148 m; Cairns 1997: figs. 1d, 4d, 7c
