Examination of type specimens for Colliculoamphora reichardtiana (Grunow) Williams and Reid, with a description of a new species, Colliculoamphora johnwrightii nov. sp.

Abstract

In the original description of the diatom genus Colliculoamphora, the type species of Colliculoamphora reichardtiana (Grunow) Williams and Reid (= Amphora reichardtiana Grunow) was mistakenly said to be from Honduras. Inspection of relevant specimens and manuscript material of Amphora reichardtiana in Grunow's collection (held in W) has permitted a re-evaluation of the species. Type material has been identified and, after examination, a new species, Colliculoamphora johnwrightii, is separated from Colliculoamphora reichardtiana.

Keywords:

• Colliculoamphora
• type material
• new species

Acknowledgements

Anton Igersheim, curator of the diatom collection in W, was immensely helpful both during my stay at Vienna and after. Charlie Jarvis (NHM) and Anton Igersheim helped decipher Grunow's Latin text and Harald Schneider (NHM) translated Grunow's German description. As ever, Pat Kociolek offered numerous helpful comments on a draft of this manuscript, and the suggestions made by two referees were most valuable.
