Platycampus Schiodte, 1839

Notes.

Two species have been considered to be represented in the West Palaearctic fauna ( Taeger et al. 2010): luridiventris (see below), and obscuripes (Konow, 1896). The latter was described from two females collected in the St Gotthard area, Switzerland. Konow (1896) stated in the original description that obscuripes differed from luridiventris in its [translated from German] "much smaller head, the apically more weakly emarginate clypeus, and the somewhat shorter third cubital cell, as well as the dark colour of the body and the legs". Only fragments of one of these specimens now exist. Conde (1937) proposed the synonymy of obscuripes with luridiventris , basing his concept of obscuripes on two female specimens from Piedmont, Italy, leg. Dodero (name of collection not mentioned), and concluded that it is only a dark, alpine form of luridiventris . A further female which may belong to obscuripes, because it has largely black metafemora, was collected in 1954 in Oberstdorf, Bavaria, by E. Enslin (Manfred Kraus Private Collection). Finally, Weiffenbach (1975) stated that he reared a female obscuripes collected on Alnus viridis , from Montafon, western Austria, 1800 m. Normally coloured specimens of luridiventris are known to occur on Alnus viridis , at lower altitudes, in Central Europe (see below). The status of obscuripes requires re-assessment, preferably including the use of genetic data.
