Megaselia steptoeae View in CoL new species ( Figs. 29 View FIGURES 28 – 30 , 61 View FIGURES 53 – 62 , 91 View FIGURES 87 – 92 , 123 View FIGURES 109 – 124 )

Diagnosis. Male. In the group III key of Borgmeier (1964), M. steptoeae keys to couplet 13 where it can readily be distinguished from both M. scopalis Brues and M. renata Borgmeier. M. steptoeae lacks the forceps-like epandrial process and strong anipisternal bristle of M. scopalis . M. steptoeae is differentiated easily from M. renata by the structure of the genitalia. In M. renata , the epandrium has a triangular notch near the rear margin and numerous stout bristles near the lower margin of the epandrium; M. steptoeae lacks such a notch and has few bristles arranged in a more-or-less vertical row on the epandrium ( Fig. 91 View FIGURES 87 – 92 ).
