Scolytodes ingae (Blackman 1943), stat. nov.

Prinosceles ingae Blackman, 1943, resurrected from synonymy in S. maurus Blandford.

Scolytodes trigonus Jordal, 2013 . syn. nov.

The holotype of Prinosceles ingae, deposited in USNM (photo: http://www.barkbeetles.info), was compared to the recently described S. trigonus and found to be identical. Scolytodes ingae was placed in synonymy with S. maurus by Wood (2007). However, S. maurus has a largely smooth pronotum, and a smooth male frons. The male holotypes of S. ingae and S. trigonus have a triangular field in the frons that becomes rough and irregularly elevated near the epistoma. They also have a tiny puncture associated with each main strial puncture on the elytra, and the interstrial granules are much larger and consistent compared to S. maurus . Another synonym of S. maurus in South America, S. medius (Eggers), looks like S. maurus, but cannot be evaluated properly due to the frons is glued in both the type (USNM) and paratypes (NHMW).
