Morphological Characteristics of Male Genitalia in Some Species of the Genus Eurytoma (Eurytomidae, Hymenoptera)

Based on the analysis of morphological characteristics of related species of the genus Eurytoma, several groups of cryptic species poorly distinguishing by external morphology, but clearly confined to certain hosts are shown to have morphological differences of male genitalia that are highly species-specific and can be useful for identification of cryptic species of the genus Eurytoma (E. rosae Nees, E. strigifrons Thomson, and E. jaceae Mayr species complexes).
