An illustrated guide to the identification and distribution of the species of Dendroctonus Erichson (Coleoptera: Scolytidae) in British Columbia

Bob Duncan

Abstract


An illustrated key is presented separating adults of the eight species of <i>Dendroctonus</i> Erichson occurring in British Columbia. Punctation on the episternal area of the prothorax and crenulations on the discal area of the clytra are used to provide reliable diagnoses of five species (<i>D. murrayanae</i>, <i>D. rufipennis</i>, <i>D. punctatus</i>, <i>D. simplex</i>, <i>D. pseudotsugae</i>) that could previously be distinguished only with considerable difficulty. Scanning electron micrographs illustrate these characters and simplify interpretation of the key. Distribution maps are provided which show many previously unpublished range extensions.

Keywords


<i>Dendroctonus</i>; Coleoptera; Scolytidae
