Atlantisina tricornis gen. et sp. nov. urn:lsid:zoobank.org:act: 0DB29D39-154D-4C9D-AF4D-F07E525B850B Figs 1E, 6 A–F, Tables 6–7 Hippoporina sp. – d’Hondt 1974: 46, fig. 6. Romancheinidae gen. et sp. indet. – Souto et al. 2016: 432. Diagnosis Frontal shield with a reticulate pattern of raised ridges around polygonal depressions; aperture with six oral spines; orifice suborbicular, proximal edge fairly straight or slightly concave, condyles short, blunt, tip somewhat thickened; suboral area with three tall thick mucrones with pointed tips, occasionally branching from their base or with bifid tips, most often with a central, vertically oriented mucro that is occasionally paired, and two mucrones proximolateral to orifice that are slightly curved and point outwards or are vertically oriented. Ooecium as long as wide or occasionally laterally compressed; ectooecium well developed, approximately covering two-thirds or more of entire ooecium; exposed endooecium relatively small, occasionally reduced to an elongated central area, surface topography similar to that of frontal shield, but usually with smaller depressions and steeper ridges. Ancestrula with nine spines, the distal four more closely spaced than (and slightly offset from) the proximal five spines, opesia slightly constricted in distal fourth, cryptocyst practically absent. Etymology Named for its prominent tridentate suboral mucro.
