Dima macedonica Schimmel, 1993: 247; Schimmel 1996: 145; Wurst 1997: 3; Cate 2007: 184; Schimmel & Platia 2008: 569.
Type depositories. Holotype, ♂ (PCPC), 2 paratypes, ♂♂ (PCPC, PCRS).
Type locality. Macedonia, Galičica, 1600 m. [YU: Makedonija].
Redetermined material. A male paratype of D. macedonica from Albania: Mt. Tomorr (PCGP) was redetermined as D. raineri (Fig. 100). Some specimens recorded under D. macedonica in Schimmel & Platia (2008) were redetermined as D. elateroides (Croatia, Montenegro; 6 ex.) and D. raineri (Greece; 7 ex.). For a female specimen from Librazhd, Albania (Fig. 101), identified as D. macedonica by Schimmel & Platia (2008), see the remarks under D. raineri. Three paratypes of D. hladilorum from Macedonia (Galičica Mts) belong under D. macedonica (Fig. 61).

Diagnosis. Dima macedonica is a medium-sized species (body length: 9.8–13.2 mm) which belongs to the group of species with more convex, suboval-shaped body and shiny elytral intervals with very sparsely distributed thin setae, similarly as e.g. D. florinensis and D. raineri (Figs 57–61). Dima macedonica is characterized by the scutellum raised above the plane of the elytra (clearly visible in lateral view; Fig. 164), distinctly double-sized punctation of pronotum, and the pubescence of the pronotal sides which is semi-erect along the whole margin length but in anterior half about 0.5 times as long as in posterior half (Figs 141–143). All these characters can be used for the separation of D. macedonica and D. raineri, which has the scutellum on the same plane as the elytra, double punctation of pronotum less distinct, with punctures more similar in size to each other (Figs 154–155, 165), and pubescence on the anterior halfs of pronotal sides shorter and decumbent (Figs 154–155). Dima florinensis shares with D. macedonica the double punctation of pronotum, but differs in the scutellum, which is on the same plane as the elytra, longer pubescence of pronotal sides, which is of about the same length along the whole margin length (Fig. 129), and by the shorter apical lobe of paramera (Figs 185, 194–197).
Intraspecific variability. The shape of antennomeres II and III is variable. Most specimens of D. macedonica have antennomeres II and III subtriangular, but in some specimens they are more elongate, as in most specimens of D. raineri (see Wurst 1997). Similar variability occurs also in D. raineri, when some specimens have similar antennomeres II and III as the typical representatives of D. macedonica. Specimens of the northern population of D. macedonica (near Ehloec) have more convex base of scutellum.
Distribution. Macedonia (Galičica Mts., Ehloec; Fig. 244).
