Abstract
A new species Diplocolenus (Verdanulus) stepposussp. n. with a Ponto-Kazakhstanian steppe distribution is described. The species is monophagous on the Volga fescue Festuca valesiaca (Poaceae). Arguments in support of the distinctness of the subgenus Verdanulus are given. Some morphological transformations of the male genitalia in the genus Diplocolenus as a whole are discussed. It is hypothesized that the subgenera Diplocolenus s. str. and Verdanus Oman spread into the Nearctic independently and at different times.
期刊介绍：
Entomological Review publishes papers dealing with all aspects of theoretical and applied entomology; and covers systematics, faunistics, zoogeography, evolution, ecology, morphology, physiology of insects, spiders and mites; as well as biological and chemical control of pests. It is one of the few entomological journals with a broad coverage.
