The aim of this work is to study the variability of a widespread moth species: Pediasia kuldjaensis Caradja, 1916, and to test the hypothesis of the existence of a complex of cryptic species within this taxon. In the work, both analysis of molecular data (study of the mtDNA COI sequence) and traditional morphological methods (study of external morphology, as well as genital structures of males and females on series) were used. It was found that P. kuldjaensis considerably varied in external features (size, wing color and wing pattern); the variability in the genitalia of males and females is much less. Among the identified six phenotypes, species separation was hypothesized for three; verification of this hypothesis by analyzing the molecular data revealed its inconsistency, all the identified phenotypes belong to the same species. Such a study of variability for species of the genus Pediasia was carried out for the first time.
