A taxonomic revision of Arnot’s Chat Myrmecocichla arnotti (family Muscicapidae)

Abstract

Arnot’s Chat Myrmecocichla arnotti in the family Muscicapidae is largely confined to the woodlands of the Zambezian biome of south-central Africa. This work assesses its taxonomic status, including comments on the so-called Ruaha Chat M. [a.] collaris (also named M. [a.] leucolaema). Based on an analysis of morphology, behaviour and molecular data, we recommend that M. arnotti be considered a single species with two subspecies: M. a. arnotti (including shelleyi, leucolaema and collaris) and M. a. harterti. A restricted type locality is proposed for Saxicola shelleyi Sharpe, 1877: Ngwesi (21°03′ S, 27°50′ E), southwestern Zimbabwe.
