Atlantia Lopez & Capel, 2020

Diagnosis.

Colonies bushy, phaceloid to dendroid, achieved by extra-tentacular budding (frequently from theca of a parent corallite at an acute angle). No epitheca. Septa normally arranged and granular. Columella poorly to moderately developed. Gender: feminine.

Type species.

Atlantia caboverdiana ( OcaƱa & Brito, 2015), by subsequent designation (Capel et al. 2020).

Remarks.

Although Atlantia resembles Cladopsammia Lacaze-Duthiers, 1897; Astroides Quoy & Gaimard, 1827; Enallopsammia Sismonda, 1871; Tubastraea Lesson, 1829; and Dendrophyllia de Blainville, 1830 in having new corallites budding from the common basal coenosteum of colony or from the edge zone of corallites, it differs by: (i) always being attached (ii) having normally arranged septa, (iii) poorly developed, and (iv) porosity of corallum consistently uniform (Capel et al. 2020).
