Dicranomyia (Dicranomyia) affinis ( Schummel, 1829) View in CoL
3 Medium-sized species (wing length 6.5–9.5 mm). Wing with pterostigma distinct (Fig. 18). Male terminalia with rostral spines shorter than those of other species ( Fig. 8 View FIGURES 6 – 10 ). Female terminalia with space between cerci very narrow, about one third width of cercus breadth at base ( Fig. 13 View FIGURES 11 – 15 ). For male tarsi, see Fig. 3 View FIGURES 1 – 5. T ............. Dicranomyia (Dicranomyia) quadra ( Meigen, 1838) View in CoL
- Small species (wing length 5.3–8.0 mm). Wing clear except for at most feebly indicated pterostigma (Figs 19, 20). Male terminalia with rostral spines normally long ( Figs 9, 10 View FIGURES 6 – 10 ). Female terminalia with space between cerci subequal in width to cercus breadth at base ( Figs 14, 15 View FIGURES 11 – 15 )............................................................................ 4
4 Two last male tarsomeres long, subequal in length, parallel-sided; tarsal claws short, with only one tooth fairly distinct ( Fig. 4 View FIGURES 1 – 5. T ). Male terminalia with rostral spines gently curved, separated at base by less than their own breadth ( Fig. 9 View FIGURES 6 – 10 ). Female terminalia with cercus about two thirds length of tergite 10 ( Fig. 14 View FIGURES 11 – 15 ). For wing, see Fig. 19................................................................................................. Dicranomyia (Dicranomyia) lutea ( Meigen, 1804) View in CoL

Male terminalia with rostral spines almost straight, separated at base by more than their own breadth ( Fig. 10 View FIGURES 6 – 10 ). Female terminalia with cercus subequal in length to tergite 10 ( Fig. 15 View FIGURES 11 – 15 ). For wing, see Fig. 20...............................................................................
