FOLIA ENTOMOLOGICA HUNGARICA ROVARTANI KÖZLEMÉNYEK XLIII. 1. 1982 p. 125-131 New records of flies from the Canary Islands (Diptera) By L. PAPP (Received December 1, 1981) Abstract: Locality data of 24 dipterous species of eight families (mainly sphaerocerids) are given. Bibio elmoi sp.n. is described from Tenerife. Through the courtesy of Professor Dr. H. FRANZ (Vienna) I had the opportunity to work on a small material of Diptera comprising 15 families, which was collected on the Canary Islands (Hierro, Gran Canaria, Tenerife). The families were represented by one or two species (except for sphaerocerids). The species of Asilidae, Empididae, Syrphidae, Phoridae, Calliphoridae, Sarcophagldae and Tachinidae were left unnamed, 15 species of eight families were identified, of which six species proved to be new to science. Five species have been described elsewhere (SOOS, 1979, PAPP and ROHÁŐEK, 1981), the sixth new species, Bibio elmo

i sp.n. is described below. Though this small material is obviously a by-product of Prof. FRANZ'

s extensive collectings of other insect groups (first of all of beetles), the high percentage of new species can be regarded as a sign of the inadequate knowledge of the dipterous fauna of the Canary Islands, contrarily to efforts that have been made in this respect (BECKER, 1908, FREY, 1936, 1958, etc.). The material from Prof. FRANZ'

s collectings was well supplemented by another material of sphaerocerids (34 specimens) collected by Senor M. BÁEZ (Tenerife) on the Canary Islands. Among the 12 species found in this latter material there is no new one (not even for the Canary Is.) but it is interesting to have numerous new records from five islands (Lanzarote, Fuerteventura, Hierro, Gran Canaria and Tenerife). Altogether 24 species of eight families were found. Acknowledgements: I should like to express my most sincere thanks to Prof. Dr. H. FRANZ (Vienna) and to Sefior M. BÁEZ (Universidad de la Laguna, Departamento de Zoológia, Tenerife) for making the interesting materials available for elaboration. I am greatly indebted to Dr. Á. SOÓS for his identifying the specimens of Lonchaeidae and Trixoscelididae, and to Dr. Á. DELYDRASKOVITS for the identification of the chloropid specimen in the present material.
