Neotypification of Catharus ustulatus (Nuttall)

Abstract

In a recent paper, I demonstrated that the original description of Turdus ustulatusNuttall, 1840, was likely based on a specimen of Catharus guttatus (Pallas, 1811). Herein, I resolve this anomaly by designating a neotype that stabilises traditional nomenclature. Formal review by the International Commission of Zoological Nomenclature determined that intervention was not necessary because neither syntype from the original description is extant or traceable. This is the third in a series of papers concerning historical aspects of Catharus taxonomy and nomenclature.
