A morphometric analysis of Anthrenus munroi Hinton, 1943, and a key for citizen scientists to the Western European species in the Anthrenus pimpinellae complex (Coleoptera: Dermestidae)

Abstract

Species that make up the Anthrenus pimpinellae complex are difficult to distinguish: a thorough examination of all the known species is required for progress in their taxonomy. Here a morphometric examination of A. munroi and its male genitalia is carried out to complement similar examinations of other species from the complex. A key is presented to differentiate among Western European species in the A. pimpinellae complex, including A. munroi. The key is aimed at citizen-scientist field images taken for submission to biodiversity websites; it relies entirely on external features that should be distinguishable in clear images.
