| Abstract: | The status of the name Amphiroa cryptarthrodia Zanardini has been uncertain, and there has been a lack of stability in this species nomenclature, in part related to its poor taxonomic foundation. The species has been considered conspecific with Amphiroa verrucosa Kützing nom. illeg. Another suggested taxonomic synonym has been Amphiroa rubra (Philippi) Woelkering. A type specimen for A. cryptarthrodia appears never to have been designated and there are no illustrations of Zanardini's original collections housed in the Museo Civico di Storia Naturale, Venezia (MCVE). In the present paper, a neotype of A. cryptarthrodia is designated, based on the study of Zanardini's authentic collections. A detailed morphological and anatomical account of the type specimen is provided and the diagnostic characters of the species are listed. Nomenclatural and taxonomic data and brief considerations of the relationships between A. cryptarthrodia and conspecific species are also provided. It is concluded that A. verrucosa Kützing is a heterotypic synonym. The name A. rubra (Philippi) Woelkerling should remain, pertaining solely to its type pending new investigations. |
