Merodon latifemoris Radenkovi ć and Vuji ć, 2011
Material examined. 1 3, quarry below Akrasi, 8.vi.2010, leg. G.E. Rotheray; 1 3, east Kalloni bay, salt marsh, 29.v.2010, leg. G. Wilkinson [NMS]; 1 3, Potamia, Anemotia, roadside, near bridge site, false fennel (yellow umbellifer), 3.vi.2010, leg. Kenn Watt [KW]; 1 Ƥ, near Neochori, 39°1´32.8˝ N 26°19´19.6˝E, in neglected olive groves in the valley immediately to the east of Neochori, 7.vi. 2010, leg. R.M. Lyszkowski [RL].
Notes. One of the diagnostic characters to separate M. latifemoris from other species of the nigritarsis group is the presence of conspicuous short black setae on the anterior face of the procoxa (Radenkoviċ et al. 2011). Variation in the position (always on anterior face of the procoxa) and number of these black setae was observed (setae sometimes less obvious), as well as variation in the size of the apical tooth of the triangular process of the metafemur. Specimens of all four species of the nigritarsis group (Radenkoviċ et al. 2011) deposited in NS were compared with our specimens, and these are unequivocally M. latifemoris. The M. latifemoris material from NS, which includes the type series, also displays the same variation in characters. Larva undescribed.
