Verdanus (Erdianus) rosaurus rosaurus   ssp. nov. ( Figs. 2 View FIGURE 2 E, 4 A–C, 4 F, 6 A–D, 9 A, 10 A, 10 B)

Description: As in V. rosaurus   sp. nov. (see above description) with apical aedeagus appendages wide ( Figs. 6 View FIGURE 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 View FIGURE 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 View FIGURE 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 View FIGURE 6 A–D).
