Type Species. Errinopsis reticulum Broch, 1951 b, by original designation.

Diagnosis. Colonies uniplanar to bushy, branching highly anastomotic (fenestrate), often with multiple attachments to substrate. Coenosteal texture a mixture of reticulate-granular and coarsely imbricate. Gastro- and dactylostyles uniformly arranged on branches. Gastrostyles present; dactylopore spines dimorphic, mound-like and horseshoe-shaped, the dactylotome facing downward (adcauline) as in Errina ; dactylostyles absent. Ampullae superficial with lateral or apical efferent pores.

Discussion. This is a rarely reported genus consisting of only two species, previously known only from Subantarctic South America.

Holocene Distribution. Off southern South America and South Africa, 250– 771 m.
