Similiclypeina Bucur, 1993

Genus Similiclypeina Bucur, 1993

TYPE SPECIES. — Similiclypeina conradi Bucur, 1993 , designated by original description.

REMARKS

The genus diagnosis by Bucur (1993: 105) is as follows: “Thallus made up of overlapping whorls of primary ramifications. Ramifications slightly tilted with respect to the axial cavity, welded at their proximal part and, usually, loose at their distal end. Overlapping whorls touching one another, partly welded into a more or less compact calcareous sheath”. Some species that were doubtfully attributed to the genus Clypeina Michelin , namely Clypeina alrawii Radoičić, 1978 , and Clypeina somalica Conrad, Peybernès & Masse, 1983 have been transferred to the genus Similyclypeina , along with the creation of the new species, Similiclypeina conradi (see Bucur 1993). For discussion on the taxonomy of Similiclypeina Bucur, 1993 and the close (synonymous?) genus Piriferella Sokač, 1996 , see Bucur (2000), Conrad et al. (2009), Bucur et al. (2000, 2021), and Granier (2013). This controversial taxonomic issue however is not influencing the present generic assignment of the Tibetan alga as, if both genera are identical, Similiclypeina would then have priority.
