Abstract

Tarsitachys bilobus (Coleoptera, Carabidae) is a fossil species described by Erwin from Baltic amber. Its description was based on only one known specimen, and thus, part of its anatomical structures were unknown as they were poorly preserved in the Holotype. In this paper we complete the description with a second specimen. A new placement among Tachyina and a new status for the genus are proposed.
