Redescription of Skrjabinus skrjabini and validity reassessment of selected species of Skrjabinus (Digenea, Dicrocoeliidae)

Abstract

Four specimens of Skrjabinus skrjabini, were isolated from two out of 93 red-backed shrikes (Lanius collurio) examined during 1962-2012. The species have been re-described and the generic diagnosis amended. Eight species of the genus have been validated: S. aenigma, S. indicus, S. latus, S. pancreaticus, S. rarus, S. skrjabini, S. similis, and S. sp. of Oshmarin (1970). Others have been reclassified as Platynosomum (P. dicruri, P. gracile, and P. talischense with synonyms P. butei and S. sp. of Oshmarin (1963)) and Zonorchis (Z. francolini, and Z. petiolatus with synonyms S. biliosus, S. gvozdevi, S. popovi). Skrjabinus petrovi is a synonym of Brachydistomum ventricosum. Lubens lubens determited by Bhuta & Khan (1975) is a synonym of S. aenigma. © 2013 Versita Warsaw and Springer-Verlag Wien.
