Abstract
Duvalius (sg. Neoduvalius) gejzadunayi sp. n. from Pećina u Dubokom potoku cave ( Donje Biševo village near Rožaje, Montenegro), the first known representative of this subgenus from the territory of Montenegro is described, illustrated and compared with the related species of the subgenus Neoduvalius Müller, 1913. This new species is characterised by depigmented, medium sized body, totally reduced eyes, deep and complete frontal furrows, 3–4 pairs of discal setae in third elytral stria, as well as by the shape of aedeagus. Data on the distribution and the ecology of this remarkable species, as well as a check-list of the subgenus Neoduvalius are also provided. Recently described genera Serboduvalius Ćurčić, S. B. Pavićević & Ćurčić, B.P.M., 2001, Rascioduvalius Ćurčić, S. B. Brajković, Mitić & Ćurčić, B.P.M., 2003, Javorella Ćurčić, S. B. Brajković, Ćurčić, B.P.M. & Mitić, 2003 and Curcicia Ćurčić, S. B. & Brajković, 2003 are regarded as junior synonyms of the genus Duvalius Delarouzée.

Summary
The Dinaric mountain chain, and the Balkan peninsula as a whole, are an impressive hotspot of subterranean biodiversity (see, as examples, Pretner 1969, 1973, 1977, Bedek et al 2006, Gottstein et al 2002, Jalžić 1984, 1994, Jalžić et al 2010). Despite the fact that the cave fauna of this region has systematically been studied for more than one and half centuries new taxa are frequently described. Intensive biospeleological research performed in the Dinaric karst region during last twenty years has led to the discovery of many new subterranean trechine taxa, species and genera (Monguzzi 1993, Casale and Guéorguiev 1994, Casale and Jalžić 1999, Quéinnec 2008, Quéinnec and Pavićević 2008, Quéinnec et al 2008, Lohaj and Jalžić 2009, Lohaj and Lakota 2010, Lakota et al 2010, Casale et al 2012, Lohaj and Mlejnek 2012).
