    For the long time С. (Morphocarabus) zawadzkii dissimilis, now synonym of zawadzkii (Lorenz, 2005), was wrongly considered as C. scheidleri pseudopreyssleri Breuning, 1932, = scheidleri helleri, or in the better case as C. zawadzkii ronayi Csiki, 1906 (Puchkov, A.V., 2008. A Review of the Ground Beetles of the Genus Carabus (Coleoptera, Carabidae) of Ukraine. Vestnik Zoologii 42 (3); Різун В.Б., 2003. Туруни Українських Карпат. – Львів.). As I remark, the true ronayi has not any relationship to zawadzkii (http://carabidae.pro/carabidae/scheidleri-ronayi-csiki-1906.html).
    Jiri Niedl (1956) in his famous work "Monografie ceskoslovenskych druhu tribu Carabini. Cast. I." doubts about validity of subspecies status zawadzkii dissimilis, and cited C. scheidleri pseudopreyssleri from the locality where I collected С.zawadzkii dissimilis.
The taxon dissimilis is a low-mountain, western population of C. (Morphocarabus) zawadzkii. It is really hardly differs exteriorly from C. (Morphocarabus) scheidleri pseudopreyssleri because of the presence of four primary intervals of elytra, the main external differential character of C. (Morphocarabus) zawadzkii , are almos absent here. This character have only a few very large females. All intervals of elytra of dissimilis are uniform and well defined, the dots here relatively large and deep. Pronotum is more narrow than in nominative subspecies. The body color is diverse.
    It should be noted that not all specimens of C. zawadzkii s.str. have four primary intervals (on 20-30% specimens of population this character are missing). The further we go from the type locality of dissimilis (Uzhgorod), and as the rise in the mountains, the more transition features to nominative form we find. But at altitudes 200-300 m where I collected beetles in this season, there were no one sample (from near 40) similar to nominative subspecies. Other population of C. zawadzkii dissimilis was found by me in the similar habitat on the north side of Carpathians Mountains (Dobromyl district, 2006). However, it is less definite externally – only the marginal forms are differ conspicuously.
