Knowledge on the taxonomic diversity and distribution of blowflies from the Madeira Archipelago is updated. New and interesting findings are reported for poorly studied islands and islets of this archipelago, together with a brief analysis of the diversity of Macaronesian Calliphoridae
s. l. Seven blowfly species were collected during this study, including the first records of Calliphora
vicina Robineau-Desvoidy, 1830, Chrysomya
albiceps (Wiedemann, 1819), Lucilia
sericata (Meigen, 1826), Pollenia
rudis (Fabricius, 1794) and Stomorhina
lunata (Fabricius, 1805) from Porto Santo, and of Calliphora
vicina, Lucilia
sericata and Stomorhina
lunata from Desertas Islands. The presence of Calliphora
loewi Enderlein, 1903 in Madeira Laurisilva forest is discussed and its first instar larva is redescribed, revealing important differences in relation to its original description. An identification key to the adult Madeiran blowflies is provided for the first time.
