Small (8-11 mm) dark species with dark legs; small and short basoflagellomere, 1-1.1 times as long as broad (Fig. 4B); oral margin notched, evident; narrow abdomen. Terga 2-4 with or without pair of narrow transversal microtrichose fasciae (Fig. 6C). Males: eyes almost touching (approaching) (Figs 3D, 13B). Male genitalia: hypandrium with smooth thecal ridge (Fig. 11C), posterior surstyle lobe elongated and triangular (Fig. 11A). Unique Palaearctic species with eyes almost touching (Fig. 3D). Female similar to M. cabanerensis , from which it can be separated by its distribution ( M. desuturinus occurs in the Balkan Peninsula, whereas M. cabanerensis is distributed in the Iberian Peninsula).
