Type species

Dermestes chalcographus Linnaeus

Adapted from Wood 1982, p. 649-656


Pityogenes can be distinguished from Ips DeGeer in having two to three declivital margin spines, with the first pair being the largest and down curved in males. Also, females often have a pit or fossa in the frons.


Species in this genus range from 1.8 to 3.7 mm in length and are approximately 2.5 to 2.7 times as long as wide. Their color varies from light brown to almost black. The pronotum is longer than wide, with the anterior half asperate. The scutellum is large and flushed with the elytra. The declivity is sulcate (concave) and armed by two or three pairs of spines, the first being the largest and downcurved in males. The vestiture consists of sparse hair-like setae. The frons is sexually dimorphic, females usually having a central fossa. The anterior margin of the compound eye is sinuate. The scape is usually as long as the 5-segmented funicle. The oval club has two bisinuate sutures on the anterior face. The procoxae are contiguous.
