The tribe Ipini (sub-tribe Ipina) contains the genera Pityokteines Fuchs, Ips De Geer, Orthotomicus Ferrari (Balachowsky, 1949) and Orthotomides Wood. Some of the characters used in previous keys in this group are not constant within a genus but are useful when combined with other characters and when exceptions are specified. This article presents a key to the genera, with a discussion of some characters that have been used in previous keys. A new species is described and new synonymy and a new combination are established.
