An account of the discovery of a dermestid beetle new to Britain, Anthrenus (A.) angustefasciatus (Ganglebauer), is described. Three individuals were found on Oxeye
daisy at Holme Green, Berkshire in May 2014. A brief description of the features separating A. angustefasciatus from A. pimpinellae (F.) is given. Morphological measurements of the specimens were taken and compared with similar measurements of A. angustefasciatus from the Mediterranean region. The possible modes of entry into the country are discussed along with the likelihood of finding further populations of A. angustefasciatus occurring in Britain
