Abstract

Abstract : Type specimens of Kützing's similarly named Synedra acus (= Ulnaria acus ) and Synedra arcus (= Tabularia arcus D.M. Williams, nov. comb.) are examined with light and electron microscopy. Their morphology is documented and their nomenclature and typification clarified. Comments are made on several other members of the genus Ulnaria that may be, or have been, confused with U. acus : Ulnaria schroeteri (Meister) D.M. Williams, comb. nov., and Ulnaria hunanensis Bing Liu, sp. nov. Tabularia minor (Kützing) D.M. Williams, comb. nov. (basionym: Synedra gailloni [var.] β minor Kützing) is also documented and characterized.
