Pensoft & Nat. Mus. Natur. Hist. Sofia, 267-278. Abstract: Fifty species from subfamily Pselaphinae (Coleoptera, Staphylinidae) from the Rhodope Mountains are reported. Four of them (Plectophloeus nubigena, Trimium graecum, Eu- plectus punctatus, Pygoxyon sp.) are new for the Bulgarian fauna. The genus Pygoxyon Reitter, 1881 is reported as a new species for the Bulgarian fauna. Key words: Pselaphinae, faunistics, Rhodopes Мountain, Bulgaria Introduction Subfamily Pselaphinae (Coleoptera, Staphylinidae) is poorly investigated in Bulgaria. The extent, to which it has been studied, is probably below 50 % (HUBENOV, 2005). So far about 125 species have been reported in Bulgaria (LÖBL & BESUCHET, 2004, HLAVÁč & al., 2007; BESUchET & BEKchIEV, 2007; BEKCHIEV, 2008). Respectively, only 10 species have been known for the Rhodope Mountains. The first data from this massif was given by Маřan (1936), and later on, data for the region were provided by KARAMAN (1948, 1969, 1972), BESUCHET (1999), BESUCHET & SABELLA (1999) and HLAVÁč & al. (2007). Materials and methods The present paper summarizes all records for this subfamily which are present in the literature. It includes also unpublished data from the collections of the Muséum d’Histoire Naturelle de Genève, the Museum für Naturkunde der Humboldt – Universität, Berlin, and the privates collections of Peter Hlaváč (Slovakia) and Albena Gjonova (Bulgaria). The material collected by the author during his expeditions in the Rhodope Mountains, carried out mainly in 2005 – 2009, is also included. The materials are deposed in the collection of the National Museum of Natural History, Sofia. 268 R. BEKCHIEV The specimens were collected sifting leaf, soil and death wood litter. The collected material was placed in a Tullgren or Winkler – Moczarski extractor. Samples were also obtained by hand turning stones and tree bark. All individuals were pinned and the aedeagus of the male specimens were mounted following the procedure explained by BESUCHET (1957). The general distribution of the species is given in alphabetical order from the catalogue of LÖBL & BESUCHET (2004).
