C o m m e n t: The original description of L. sodale distinctiventre is based on two male syntypes from "Krujcienko, Dukajca". Both syntypes were located in the Frey collection at the NHMB ; one of them is designated as the lectotype. The taxon has been treated as a subspecies since its original description, and has been recorded from Poland, Slovakia, and the Czech Republic ( SMETANA 2004) .

According to KOCH (1939a), P. s. distinctiventris is distinguished from the nominate subspecies by a slightly different morphology and chaetotaxy of the male sternite VIII and by the slightly different shape of the ventral process of the aedeagus. An examination of the type specimens of both P. distinctiventris and of P. sodalis (see ASSING 2003d) confirmed the differences specified by KOCH (1939a). They are rather pronounced, constant, and clear-cut, and they evidently coincide with distinct distribution patterns, so that both taxa are regarded as distinct at the species level. The distribution of P. distinctiventris appears to be confined to the Carpathians.
