Vujić, Ante, Radenković, Snežana, Ačanski, Jelena, Grković, Ana, Taylor, Mike, Şenol, Serdar Gökhan & Hayat, Rüstem, 2015, Revision of the species of the Merodon nanus group (Diptera: Syrphidae) including three new species, Zootaxa 4006 (3), pp. 439-462 : 448

Merodon nanus Sack

Diagnosis. Male genitalia: tip of posterior lobe of the surstylus rounded, directed anteriorly ( Fig. 5 A: ps). Aedeagal box elongated, 1/3 of length of hypandrium ( Fig. 5 B: ab; 5C: ac); distal end of the aedeagal box is strongly bifurcated in the ventral view ( Fig. 5 C). This latter character is very stable in all analyzed populations across a wide range of species, from Lesvos through Turkey as far as Israel, Iran and Armenia; and is the main diagnostic character that distinguishes M. nanus ( Fig. 5 C) from closely related M. rasicus sp. n. ( Fig. 5 D). In addition, the rounded posterior surstyle is a unique character within this group (the posterior margin of the posterior surstyle is convex, contrary to all other species where it is more or less straight). Inner processes are settled in the apical 1/4 of the hypandrium ( Fig. 5 B: ih).
