Comparison of homologous structures of the male terminalia in Macrocera lutea Meigen, 1804, and Kelneria rovnensis sp. nov. The drawing of M. lutea is redrawn from Matile (1990). Remarks: The dashed line at the boundary between the gonocoxite and gonostylus indicates the poor visibility of the separating margin, most likely resulting from a partial fusion of these two structures. The arrow marks the inferred line of separation.	Figure 6. Comparison of homologous structures of the male terminalia in Macrocera lutea Meigen, 1804, and Kelneria rovnensis sp. nov.
