Abstract

New species of Syrphini and Melanostomatini for the Iberian fauna (Diptera, Syrphidae)
Epistrophe melanostoma (Zettersted, 1843), Dasysyrphus tricinctus (Fallén, 1817), Dasysyrphus venustus (Meigen, 1822) and Platycheirus sticticus (Meigen, 1822), are cited for the first time in the Ibenan peninsula. All specimens were collected during 1986, 1987 and 1988 in the Cantabrian mountain of range which is located in the Iberian eurosiberian region. The diagnostic of morphological characteristics of this four species are indicated. The diferences and similanties with its Iberian congeneric species, are presented in an identification key.
