Aneuclis aenigmatica, a new remarkable species from Southwestern Mexico (Hymenoptera: Ichneumonidae: Tersilochinae)

Abstract

A new tersilochine species, Aneuclis aenigmatica Khalaim et Ruíz-Cancino, sp.n., is described from the State of Jalisco in Southwestern Mexico. In spite of the fact that the species is represented by a single poorly preserved male without antennae, it is immediately distinguished from all North American congeners by the head lacking occipital carina dorsally, infumate with brown wings and very short metacarpus.
