Taxonomic history

Xyleborus pseudocomans Eggers, 1930: 187.

Hadrodemius pseudocomans (Eggers): Wood and Bright, 1992: 819.


Xyleborus artecomans Schedl, 1953c: 24. Beaver, 2010: 55.


6.0–7.2 mm long (mean = 6.86 mm; n = 5); 1.8−1.9 times as long as wide. This species can be distinguished by its larger size; elytral declivity strongly impressed, sides of impression raised and bearing tubercles or rugosities; and elytral impression bearing fairly sparse, long hairs or short hairs only.

This species is most similar to H. comans, from which it can be distinguished by the strongly impressed declivity rather than the declivity plano-concave from suture to interstriae 3.
