Coenagrion pulchellum

The Caucasian specimens of C. pulchellum do not show any transition towards the related and externally very similar species C. persicum confined to Central Iran, following the delicate morphological differences between these species illustrated by Schneider et al. (2016). C. persicum differs from C. pulchellum as follows: males: tooth disposed almost at middle of trunk ( Fig. 2n ) rather than at ca 2/3 of its length ( Fig. 2o–q ); paraproct prominence directed caudad ( Fig. 3n ) rather than ventro-caudad; ( Fig. 3o–q ); females: incisions between pronotum lobe sinuous ( Fig. 7i ) rather than more or less triangular ( Fig. 7j ).
