The species of the genus Diamesa (Diptera, Chironomidae) known to occur in Italian Alps and Apennines Author Montagna, Matteo Author Urbanelli, Sandra Author Rossaro, Bruno text Zootaxa 2016 4193 2 317 331 journal article 10.11646/zootaxa.4193.2.7 4a1140ea-fe86-4b33-9ee7-2f933c97a856 1175-5326 166939 A1A56E2F-3A9A-4A07-B3BB-EE50B669FB50 Diamesa permacra (Walker, 1856) ( Fig. 1 C, D) The species can be easily identified on the basis of the shape of the aedeagal lobe bearing only fine spines at apex ( Fig. 1 C, D). There is an old drawing of this species ( Pagast 1947 ), and the most recent ones are in Serra-Tosio (1971b) . In the paper with the original description of D. thomasi Serra-Tosio, 1970 (the dampfi group), some other diagnostic details are also provided. In Italy , only an adult male associated to pupal exuviae was collected in Acqualba stream in 1978 ( Prealps, NO ). Larvae and pupal exuviae cannot be separated from D. dampfi ; the larvae and pupae recorded in few localities in Prealp springs ( Rossaro & Lencioni 2015a , b ) probably belong to D. permacra .
