Trematotrochus verconis.–Cairns & Parker, 1992: 30–31, figs. 9a,e (SA).– Cairns, 1998: 388, figs. 4h,i, 5a–c (synonymy, WA).
Foveolocyathus verconis.–Cairns, 1997: 26–27, pls. 3e, 6b, 9f (remarks).
Holotype. The specimen incorrectly designated as neotype of Trematotrochus verconis by Cairns & Parker (1992): SAM 542. Type Locality: Cape Borda, Kangaroo Island, 101 m.
Remarks. As explained below, my previous concept of F. verconis was re-evaluated when I examined the rediscovered type material of T. verconis and realized that it was conspecific with Foveolocyathus alternans Cairns & Parker, 1992. Thus, the species F. alternans becomes a junior synonym of F. verconis, and the species I had understood as F. verconis and for which I designated a neotype (Cairns & Parker, 1982) requires a new name. For this species, fully described and illustrated by Cairns & Parker (1992) and Cairns (1998), I now rename Foveolocyathus parkeri, in honour of Shane Parker.
Distribution. Southwestern Australia and South Australia; 73– 183 m.
