Key to males of the Pollenia haeretica species-group

1 Cerci broad in dorsal view ( Fig. 4 ); apex appearing truncated ( Fig. 4 ), slightly upturned in lateral view ( Fig. 5 ) and covered with a very conspicuous and very dense brush of brownish setulae ( Fig. 6 ). In lateral view the long erect setae present on the dorsal surface of the cerci proceed distally all the way to the tip ( Fig. 5 ). Pregonite a broad-based triangle in lateral view ( Fig. 3 ). Frons at narrowest / head width ratio 0.121–0.158..........1. Pollenia haeretica Séguy

- Cerci narrow in dorsal view ( Fig. 19 ); apex long, pointed ( Fig. 19 ), not upturned in lateral view ( Fig. 20 ) and covered with an inconspicuous, sparse brush of yellowish setulae ( Figs. 21 , 28 ). In lateral view the long erect setae present on the dorsal surface of the cerci are absent on the distal half ( Fig. 20 ). Pregonite narrower, distally with almost parallel edges ( Fig. 18 ). Frons at narrowest / head width ratio 0.100–0.108........................... 2. Pollenia ibalia Séguy
