Genus Inferiolabiata Broch, 1951

Errina (Labiata) Broch, 1942: 39 (in part).

Errina (Inferiolabiata) Broch, 1951b: 125 .—Cairns, 1983a: 107. Inferiolabiata: Cairns, 1983b: 447 —448; 1991: 40; 1992: 540, 544 (key).

Type Species. Errina labiata Moseley, 1979 , by original designation.

Diagnosis. Colonies uniplanar or bushy, often modified by a commensal polynoid gall tube. Coenosteal texture reticulate-imbricate. Gastro- and dactylopores uniformly distributed, however dactylopore spines sometimes arranged in crescents. Gastrostyles elongate, often stabilized with transverse tabulae. Dactylopore spines horseshoe-shaped, the dactylotome facing upward (abcauline). Dactylostyles multiple per dactylopore. Ampullae superficial hemispheres.

Discussion. Only four species are known in the genus, this being the first record from off South Africa. The three previously described species were compared by Cairns (1991: Table 4).

Holocene Distribution. Antarctic and Subantarctic, cold temperate New Zealand and South Africa, tropical southwest Indian Ocean, 87–2100 m.
