Redescription.

This species strongly resembles M. thaica Grootaert & Shamshev, 2009, except for the following features. Postpedicel brown in contrast to yellow pedicel. Mid tarsomere 1 about 2.5 times as long as mid tarsomere 2. Terminalia (Fig. 11 ) very small, brownish yellow, rather subglobular. Cerci separated; right cercus digitiform, slightly tapered, with several long unmodified setae; left cercus longer and stronger than right cercus, digitiform when viewed dorsally, somewhat narrowed subapically, subrectangular when viewed laterally, with several long unmodified setae. Epandrium completely divided. Right epandrial lamella subrectangular (viewed laterally), with numerous long setae on apical half. Right surstylus not prominent. Left epandrial lamella separated from hypandrium, with 1 short seta apically. Left surstylus differentiated from epandrium, represented by two elements; upper lobe bilobed, with cluster of long bristles on one lobe, two long bristles on second lobe; lower lobe strongly sclerotised, with cluster of shorter, spine-like setae. Hypandrium with 3 short setae apically. Phallus very short. Ejaculatory and ventral apodemes subequally long.

Remarks.

The male terminalia of M. starki sp. nov. are similar to those of M. europaea , but different in many details. The most obvious difference is that the upper lobe of the left surstylus is short and bifid in M. europaea , but long digitiform in M. starki sp. nov.

Distribution.

Hungary, Slovakia.
