Diagnosis. Male genitalia: tip of posterior lobe of the surstylus triangular, entire posterior lobe of the surstylus relatively small ( Fig. 9 A). Aedeagal box elongated, 1/2 to 1/3 of length of hypandrium ( Fig. 9 B: ab); shape of aedeagal box with small variations in apical part ( Fig. 10 ). Inner processes settled in apical 1/4 of hypandrium ( Figs. 6 C, 8B:ih). FIGURE 9. Male genitalia of Merodon rasicus sp. n. , lateral view. A. epandrium; B. hypandrium; ab—aedeagal box; n—notch on theca to which is attached the aedeagal apodeme; ih—inner processes of the hypandrium. FIGURE 10. Aedeagal box of Merodon rasicus sp. n. A–L. ventral view; A–F. lateral view; G–L. Turkey, Hakkari: A,G. Iran, Fars Darab: B,H. Greece, Kavala: C,I. Turkey, Mardin: D,J. Serbia, Kopaonik: E, K. “Poland”: F, L. This is a species with a broad range, from Serbia through Greece and Turkey to the Caucasus and Iran . Different populations show small variations in the shape of their aedeagal box ( Fig. 10 ) and posterior lobe of the surstylus, which can indicate the presence of more geographically isolated populations; however, based on the identical structure of other male genitalia features, we described M. rasicus sp. n. as one taxon.
