Revisione dei Tychus del gruppo dalmatinus, con descrizione di nuovi taxa (Coleoptera : Pselaphidae) [Revision of Tychus of dalmatinus group, with description of new taxa (Coleoptera : Pselaphidae)]

The revision of the species of the genus Tychus belonging to the dalmatinus group not considered in a previous work (BESUCHET & SABELLA, 1996) is given : Tychus dalmatinus Reitter, 1880 of southern Europe, Turkey and Caucasus; Tychus ibericus (Motschulsky, 1835) of north-eastern Turkey; Tychus bosnicus Ganglbauer, 1897 of Bosnia-Herzegovina; Tychus bescidicus Reitter, 1901 of eastern Austria, Czech Republic and Rumania; Tychus tritomus Dodero, 1919 of Corsica and Sardinia; Tychus reitteri Karaman, 1955 of Crete; Tychus affinis Besuchet, 1958 of Tajikistan and Uzbekistan; Tychus henroti Meggiolaro, 1966 of Cyprus and Tychus sbordonii Meggiolaro, 1967 endemic of Latium (central Italy). For each species the most important bibliographic citations, the peculiar morphological characters- with particular reference to the antennae, aedeagus and telisternite- and the geographic distribution are given. Four new species are also described : Tychus cilicicus, sp. n. and Tychus pamphylicus, sp. n. from southern Turkey, Tychus rhodensis, sp. n. from Rhodes and south-eastern Turkey and Tychus argolicus, sp. n. from Peloponesian (southern Greece). The group probably includes also Tychus kurilensis Kurbatov, 1992 from Kuril islands. The synonymy Tychus mutinensis Reitter, 1884 = Tychus dalmatinus Reitter, 1880 is re-proposed based upon the examination of abundant material. Also, the neotype of Tychus ibericus (Motschulsky, 1835) are designated.
