The external morphology is described, as well as the
gross morphology of the central nervous system, alimentary canal
and reproductive systems. Sexual dimorphism is shown by the
first visible abdominal sternite, the mucro of the hind tibia
and to a lesser extent by the structure of the base of the prothorax.
The immersion of the head and muzzle-like rostrum into
the anterior part of the prothorax and the absence of a crop,
proventriculus and metatergum distinguish this insect from all
known Curculionidae. Its inclusion in a separate subfamily,
the Cryptopharynginae is therefore justified and its nearest relatives
appear to be the Scolytinae.
