Calliphora rohdendorfi (Grunin, 1966) (Diptera: Calliphoridae): a new blow fly in the Italian fauna detected in Calabrian Apennines

Abstract

Within the family Calliphoridae, the genus Calliphora Robineau-Desvoidy, 1830, includes species of medical, veterinary and forensic relevance. This study reports for the first time the presence of Calliphora rohdendorfi (Grunin, 1966) in the Italian territory, namely in Calabrian Apennines (Southern Italy). The adults of the species were captured by bait bottle and yellow pan traps within a monitoring project of Diptera Brachycera involving Parco Nazionale dell’Aspromonte (Aspromonte National Park), Parco Nazionale della Sila (Sila National Park) and Parco Naturale Regionale delle Serre (Natural Regional Park of Serre), between 2018 and 2021. Calliphora rohdendorfi was identified on detailed morphological bases of both sexes. This was the first description of the general morphology of the female and its terminalia through digital photographs acquired by stereomicroscopy. The species was captured in pine and beech forests at an altitude between 1010 and 1820 m a.s.l. in shaded mountain areas. Prior to the finding in Southern Italy, this species showed an unusually disjointed distribution in Caucasus, Germany and Poland, thus the presence of C. rohdendorfi in Calabrian Apennines provides new and interesting data that require further investigation, because the species could play a role as flower visitor, pollinator and forensic indicator.
