Diagnosis: Aphelinoidea anatolica s.str. belongs to the A. (Aphelinoidea) plutella

species­group­as­defined­by­Walker­ et al. (2005) (= the renamed anatolica species

group of Trjapitzin 1995), because it has a hyaline, sparsely setose (with very

short, light-colored microtrichia) transverse path on the fore wing disc just beyond

the venation ( Figs 8, 12). The mesosoma of female is more or less uniformly
