Dima vailatii is a medium-sized species (body length: 9.5–13.0 mm) with suboval body, pronotum with fine, dense and moderately deep punctures, intervals shiny, with pubescence on the pronotal sides short, decumbent along almost the whole length, with elytral pubescence dense, short, decumbent, with moderately shiny intervals, and with the scutellum slightly raised above the elytral plane ( Figs 109–113 , 158–160 ). Dima vailatii differs from all other species occuring in the surrounding mountain ranges ( D. kozufensis sp. nov. , D. lebenbaueri and D. florinensis ) by the pubescence of pronotal sides, which is short, curved, decumbent and of the same length almost along the whole length; with distinctly longer hairs only at hind angles. Additionally, D. kozufensis sp. nov. and D. lebenbaueri differ from D. vailatii by the sparser pronotal punctation ( Figs 138–140 ) and D. florinensis by sparsely pubescent elytra with fine setae ( Figs 31–34 ). Male genitalia is as in Figs 217–219 . Intraspecific variability. There is a variability in body coloration within this species. Paler specimens were collected mainly on the southern slopes of Kajmakčalan in the forested gorges in the surroundings of Agios Georgios ( 950–1340 m ), but they are known also from other parts. The darker specimens ( Figs 111–112 ) were collected mostly in the beech forests on the southern slopes ( 1340 m ) and in the eastern part of the mountain range ( 1563–1573 m ). The highest known locality lies in a pine forest ( 1820 m ), where the smallest specimens were collected. Distribution. Greece (Voras Mts., Kajmakčalan; Fig. 244 ). Remark. We did not find any morphological differences between D . vailatii and D . riesei ( Figs 109, 113 ). Therefore, we herein synonymize Dima riesei Platia, 2010 under Dima vailatii Schimmel & Platia, 2008 .
