Key to the world species of Ips (Coleoptera: Curculionidae: Scolytinae)

About the key

A matrix key designed to allow maximum diagnostic inference from male or female specimens of Ips DeGeer, 1775, including damaged specimens.

Morphologically similar genera of Ipini, Orthotomicus and Pseudips, are included at genus level to help distinguish Ips from these other genera.

Numbers in parentheses in natural language descriptions indicate outlier values observed in only a few specimens.

Key accompanies an article in the Canadian Journal of Arthropod Identification (Douglas et al. in press). This article includes a dichotomous key, and illustrated diagnostic fact sheets for all Ips species and subspecies.
