FAUNISTICAL REMARKS The Anisotomini fauna of the Caucasus is composed as follows: Anisotoma (2 spp.), Amphycillis (2 spp.), Cyrtoplastus (1 sp. ) , Agathidi urn (27 spp.: 1 sp

. of subgenus Cyphoceble

, 14 spp. of subgenus Neoceble and 12 spp. of Aga thidi urn s. str.). The contrast in generic and subgeneric composition between faunae of the Caucasus and the neighbouring Turkey is evident from Table 1. It is clear from Table 1 that there is a great deal of similarity between the Caucasian fauna and that of the Middle European countries (Germany, for example) or the Mediterranean Region (Italy, Yugoslavia). As regards the number of species, the subgenus Neoceble surpasses Agathidium s. str. in these regions. On the other hand, only Turkey and North Africa exceed the Caucasus in the number of endemic species. High level of endemicity is a general characteristic of the regions situated at the margins of the area of distribution of such tribes like Anisotomini. As far as the morphology is concerned, the Caucasian Anisotomini share in no particular feature except for Agathidium fronticorne REITTER whose male possesses a prominent horn at the centre of the clypeal line. Altimetric distribution of some of the most significant and interesting Anisotomini from the Caucasus is demonstrated in Table 2. Endemic species: Cyrtoplastus successor REITTER, Agathidium nasicorne REITTER, A. tenuicorne REITTER, A. fronticorne REITTER, A. filicorne REITTER, A. lederi REITTER, species present only in the Caucasus and in one of the adjacent region: Agathidium clavulum REITTER (north Iran), A. suturaié REITTER (Turkey), A. caspicum REITTER (north Iran), A. caucasicum REITTER (Turkey), A. circassicum REITTER (the Crimea).
