Northern Apennines as centre of speciation: a new Verdanus species group (Hemiptera, Cicadomorpha, Cicadellidae) from Italy and its phylogenetic relationships with V. bensoni and the V. limbatellus group Author Guglielmino, Adalgisa Author Bückle, Christoph text Zootaxa 2009 2264 1 22 journal article 10.5281/zenodo.190799 a419656c-eebb-4f69-9db4-f254cf9b1e91 1175-5326 190799 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).
