oa African Entomology - Histeridae (Coleoptera) associated with cycads in South Africa, with taxonomic notes on Afrotropical Exosternini (354KB
Pachycraerus chalybeus (Fiihraeus), P. desidiosus Marseul and Diabletes fossistoma (Marseul) are recorded from cones and stems of several species of Encephalartos Lehmann (Gymnospermae: Cycadales) from South Africa. Pachycraerus spatiosus Lewis, formerly a synonym of P. cyanescens Erichson, is proposed as a new synonym of P. alluaudi Marseul. The genus Diabletes Reichardt is transferred from the tribe Platysomatini to the tribe Exosternini, based on the structure of the antennal club. Diabletes fossistoma (Marseul) is redescriptionbed. A key to the Afrotropical genera of Exosternini with S-shaped tarsal grooves on the protibiae is also provided.
