C o m m e n t: Ochthephilum collare was originally described as a variety of O. fracticorne and subsequently treated as a distinct species ( ZANETTI 1980; HOZMAN 1985). The original description is based on an unspecified number of syntypes from "Knin in Nord- und Metkovic in Central-Dalmatien" (REITTER 1884). The only syntype located in the Reitter collection at the HNHM, a male from Knin, is designated as the lectotype.

The species is subject to considerable intraspecific variation, not only of external characters such as size, coloration, and the length of the elytra, but also of the size, shape, and internal structures of the aedeagus (Figs 1-7, 14-19). The body of most examined specimens is uniformly blackish. In some beetles, the pronotum is of reddish-brown coloration; rarely, the whole forebody is more or less brownish. The hind wings of the brachypterous morph are of reduced length, but distinctly longer than the elytra. Besides the somewhat longer elytra, this is the only external character reliably separating brachypterous O. collare from brachypterous O. fracticorne .

D i s t r i b u t i o n a n d b i o n o m i c s: Ochthephilum collare appears to have a distribution of the Ponto-Mediterranean type ( Map 1 ). According to ZANETTI (1978), HOZMAN (1985), and SMETANA (2004), O. collare is widespread in the Mediterranean, Central and Eastern Europe, and southern Scandinavia. However, based on the material revised in the present paper, its presence in southwestern Europe seems highly unlikely. According to TRONQUET (2006), there is no reliable record from the eastern Pyrenees. Previous records from the Iberian peninsula are probably based on misidentifications and should be considered doubtful. The same applies to the record from Tunisia ( SMETANA 2004), which probably refers to O. brevipenne . Based on the revised material, the distribution ranges from the western Caucasus region, southern Greece, and southern Italy to southern Sweden. The above specimens from Albania, Bosnia-Herzegovina, Bulgaria, Slovakia, Yugoslavia, and Georgia represent the first records from these countries.

In the north of its range (southern Scandinavia, northern and central parts of Central Europa), O. collare is generally absent from swamps, bogs, and riverine habitats, where it is replaced by O. fracticorne , but almost exclusively found in coastal habitats, inland saline habitats, anthropogenic habitats such as pits, etc. In the southern parts of its distribution, however, it is more eurytopic and encountered in a wide range of moist habitats.
