oa African Entomology - Phylogenetic significance of wing characters in the Trogidae (Coleoptera: Scarabaeoidea)

Volume 1, Issue 2
  • ISSN : 1021-3589



Wing characters of the family Trogidae are examined and analysed phylogenetica1ly. Based on an analysis of 33 characters, the family was found to comprise two lineages, a primitive Trox lineage, and a derived Polynoncus + Omorgus lineage. The wing characters and their analysis confirm the validity of the genera as presently recognized, as well as the proposed relationship amongst genera as found in previous studies of other character suites. Morphological evidence is also presented on incipient aptery in O. bates; (Harold), the only representative of the South American Omorgus (Haroldomorgus) Scholtz.
