The water mites of the family Hygrobatidae (Acari, Hydrachnidia) in Italy Author Gerecke, Reinhard text Zootaxa 2021 2021-07-30 5009 1 1 85 http://dx.doi.org/10.11646/zootaxa.5009.1.1 journal article 10.11646/zootaxa.5009.1.1 1175-5326 5157635 3E5643F0-BBC2-45FA-83E5-07FEF6ECB690 Atractides ( s. str. ) panniculatus K. Viets, 1925 (Figs 30 L-N; 32 D) Material examined. Calabria : I 433, 1/0/0 slide. Trentino-Alto Adige : I sa 110, 3/4/0 slide. Previously published records from Italy : Trentino-Alto Adige ( Crema et al. 1996 , Gerecke et al. 2009 ). Records from Sicily (“ Atractides sp. prp. panniculatus ” Gerecke 1991, Ferrito 1994 ) do not refer to A. panniculatus , but to various different species – the material in question is revised in the present paper. Remarks: With regard to several measurements, the specimen from Calabria is at the lower level of the range established for Central European populations. The distoventral margin of P-2 is more protruding than in typical Central European specimens, but not as distinct as in A. fissus . The arrangement of the Ac in a close triangle, with Ac-1 nearly touching Ac-3 is observed in both species. Features in the specimen from Calabria found typical for A. panniculatus , in contrast to A. fissus , are major coxal field measurements L 380, in A. fissus <350), relatively small Ac (diameter <60, in A. fissus > 60), and a relatively stout I-I-5 (dL/HB 3.2, in A. fissus > 3.7). Habitat: Crenobiont. The Calabrian record from a spring in beech forest at high elevation, 1750 m . Distribution: Central and Southern Europe, Asia Minor .
