Ipini

European spruce bark beetle Ips typographus. copyright Giles San Martin.

Belongs within: Hylesininae.

The Ipini are a cosmopolitan genus of bark beetles with the rear face of the elytra more or less excavated, with the lateral margin typically armed by tubercles or spines. All are phloeophagous and the majority are heterosanguineously polygynous. The African genus Dendrochilus is distinguished having the eyes short, oval and entire (vs more elongate and anteriorly sinuate in other genera) and the posterior elytral declivity poorly developed. Pityogenes and Pityokteines have a rather narrowly bisulcate elytral declivity with rather broadly elevated, rounded lateral margins (Wood 1986).
