Grzegorzekia collaris (Meigen) Fig. 10 Diagnosis. The combination of the following characters will distinguish this species from Nearctic congeners: abdominal tergites without pale posterior bands (though tergites may have anterolateral pale areas on some or all of tergites 2–7); male mid-tibial organ absent; in lateral view, gonocoxites with two lobes, the anterior lobe bearing a comb of stout, black, spine-like setae; aedeagus triangular, shorter, not reaching apex of gonocoxites; female sternite 8 undivided, but with a posteromedial emargination with two patches of stout, black, spine-like setae (one patch on each side of the median emargination with each patch bearing 2–3 setae)(Fig. 10). The male terminalia were photographed by Chandler (2015) and male and female terminalia illustrated by Chandler (1999). Material examined and Distribution. No Nearctic specimens have been examined, but a male and female from Slovakia have been studied (SFC). The only record of this species in the Nearctic region is from a single male recorded from Valdez Glacier Campground, Valdez, Alaska (Zaitzev, 1993). Remarks. Zaitzev’s (1994) concept of this species (based on the illustration of the male terminalia) is consistent both with the concept of this species as illustrated by Chandler (1999) as well as with the material studied herein from Slovakia. : Published as part of Fitzgerald, Scott J., 2019, The Nearctic species of Grzegorzekia Edwards (Diptera: Mycetophilidae), pp. 163-174 in Zootaxa 4623 (3) on page 164, DOI: 10.11646/zootaxa.4623.1.11, http://zenodo.org/record/3253496 : {"references": ["Chandler, P.
