Actinocyclus abscheronica Molinari & Guiry , nom. nov.

Replaced name: Actinocyclus paradoxus Makarova , Notulae systematicae e sectione cryptogamica instituti botanici nomine V.L. Komarovi academiae scientiarum URSS 12: 83, 1959 (Ochrophyta, Hemidiscaceae ), nom. illeg., non Actinocyclus? paradoxus Ehrenberg (1854: 7 , pl. XX, sect. I: fig. 41), Hemidiscaceae .

Notes: The species is renamed after the type locality, Absheron Peninsula, in the Azerbaijani coast of the Caspian Sea. The Latin adjective “ abscheronica ” was employed by Eichwald (1831: 5). Actinocyclus paradoxus Ehrenberg was validated by an illustration (Arts 38.5, 38.7-10) of an incomplete valve with a distinctive perforation pattern ( Ehrenberg 1854).
