Xyleborus permarginatus Schedl, 1933 : 200 . Ambrosiodmus permarginatus (Schedl) : Wood & Bright, 1992 : 678 . Taxonomy: Images of the holotype (NHMW) taken by Alexander Petrov, and a paratype (FRI) taken by AIC were examined. The species is transferred to Immanus Hulcr and Cognato, 2013 , because of the following characters: large body size, robust form, truncate declivity, pronotum anterior margin with elevated carina, pronotal disc asperate, tibial denticles reduced, and tibial edge appearing very uneven.
