Description of the larva of Cordulegaster mzymtae Bartenef, 1929, with a discussion of its taxonomic position (Anisoptera: Cordulegastridae)

A young (F-2) female cordulegastrid larva from the northern slope of the Pontic Alps (NE Turkey) is described and illustrated. It obviously pertains to C. mzymtae, the only Cordulegaster from the mountain forests along the eastern Black Sea coast of which the larva was still undescribed. The taxonomic position of the species within the genus is discussed, on the basis of a morphological comparison with larvae of C. boltoni, C. insignis and C. bidentatus. Its closest relative is found to be C. bidematus. Notes on the larval habitat are provided, and its significance for the distribution of C. mzymtae is stressed.
