Verdanus (Erdianus) rosaurus rosaurus ssp. nov. (Figs. 2 E, 4A–C, 4F, 6A–D, 9A, 10A, 10B) Description: As in V. rosaurus sp. nov. (see above description) with apical aedeagus appendages wide (Figs. 6 A–D). Measurements: Males. Total body length (from vertex to tip of fore wings) 3.80–4.36 mm; width of head including eyes 1.20–1.32 mm; length of vertex 0.48–0.60 mm; length of pronotum 0.44–0.52 mm; width of pronotum 1.12–1.24 mm; length of genital plates 0.43–0.49 mm; length of aedeagus shaft (from basis to phallotrema) 0.38–0.42 mm. - Females. Total body length (from vertex to tip of fore wings) 3.72–4.24 mm; width of head including eyes 1.28–1.40 mm; length of vertex 0.56–0.60 mm; length of pronotum 0.48–0.56 mm; width of pronotum 1.12–1.36 mm. Type series: See above for Verdanus rosaurus sp. nov .. Geographic distribution: V. rosaurus rosaurus is so far known only from Alpe di Succiso and M. Navert (Fig. 1: circle), in an altitude between 1450 and 2000 m. Biology: Adults were collected in June and August in mountain meadows characterized by the presence of Brachypodium (perhaps one of its host plants) (Fig. 2 C). At the beginning of June prevalently (77%) males and only few females were found besides many nymphs, whereas in the middle of August females clearly were prevailing (82%). Probably univoltine. Remarks: The diagnostic character of this subspecies consists in the wide apical aedeagus appendages (Figs. 6 A–D).
