Diagnosis. Dima raineri is a medium-sized species (body length: 9.0– 13.5 mm) with a more convex, suboval body and shiny elytral intervals with very sparsely distributed thin setae (Figs 9 6–100). This species is characterized by the pubescence of the pronotal sides, which is short decumbent in anterior third or half and longer semi-erect posteriorly (Figs 154–155). This type of pubescence is present also in D. dusaneki sp. nov. but it differs in the more robust body and the shape of pronotum (wide, evenly convex, more rounded laterally; Figs 20–21). Similar species, D. macedonica, has the scutellum raised above the plane of the elytra (Figs 164–165), more distinctly double-sized pronotal punctation (punctures more like each other in size in D. raineri, larger differences between the size of punctures in D. macedonica; Figs 141–143, 154–155), head and pronotum surface in most cases more densely covered with pubescence, and the pubescence on the pronotal sides semi-erect along the whole margin length (although shorter at anterior half; Figs 141–143), and D. florinensis has also the punctures on pronotum of two distinct sizes and longer pubescence on the pronotal sides, which is of about the same length along the whole margin length (Fig. 129). Male genitalia is as in Figs 210–213.
Intraspecific variability. The striae on the elytra are variable in this species. The holotype and some specimens are distinctly striate, but usually the striae are weakly developed and in some cases they are replaced by the rows of punctures, mainly in the posterior half. Some smaller specimens with the rather smooth elytra with sparse punctures (i.e. those from Grammos) may resemble D. elateroides but they can be easily distinguished by the almost smooth pronotum and oval scutellum. Additionally, the shape of antennomeres II and III is variable. Most specimens of D. raineri have antennomeres II and III elongate, but in some specimens they are more subtriangular (or at least antennomere III), similarly as in typical D. macedonica (see Wurst 1997). This variability led to the several misidentifications between these species (Schimmel & Platia 2008).
Distribution. Albania (Mt. Tomorr), Greece (Vório Bóïo Mts., Grammos Mts., Pindos Mts.) (Fig. 244). First record for Albania.
Remarks. Schimmel & Platia (2008) did not study the holotype of D. raineri described from the northern part of Pindos Mts. (deposited in the SMNS). Instead, they used a pale specimen of the another (but Peloponnesian) species as a representative of D. raineri and the diagnosis and all conclusions are based on that specimen (Fig. 84). Unfortunatelly, the specimen from the Peloponnese, which Schimmel & Platia (2008) thought was D. raineri, actually represented a species described newly in the same study from several other specimens as D. parnonensis (Schimmel & Platia 2008). What is more, as a result of the above mentioned confusion, specimens of the real D. raineri were newly described in the same study as D. pindosensis (Schimmel & Platia 2008; Fig. 99). Therefore, we herein synonymize Dima pindosensis Schimmel & Platia, 2008 under Dima raineri Wurst, 1997.
The specimen from Mt. Tomorr, Albania, which was originally described as a part of the type series in D. macedonica, is definitely more like D. raineri than to D. macedonica (e.g. in the shape of the scutellum and in the pronotal punctation; Fig. 100), however, its pubescence of the pronotal sides is almost missing (Fig. 100). This specimen represents the northernmost known population of this species (Fig. 244).
Additionally, we studied a dark brown female from the Elbasan county, Albania (locality label as follows: Albania, Librazhd, Shebenikut Qarishte env., 1500 m, 3.VII.2001, leg. P. Moravec; PCJM), which was identified as D. macedonica by Schimmel & Platia (2008) (Fig. 101). This specimen is much more like D. raineri in the pronotal punctation and pubescence of pronotal sides (Fig. 155). However, it is about 70 km farther north from the known D. raineri distributional range, closer to the area of D. macedonica (Fig. 244). This female might be a teratological specimen; it has the strongly transversely convex pronotum in the posterior half, distinctly convex basal and central parts of elytra and only weakly developed elytral striae (Fig. 101). Unfortunately, we are not able to properly determine this specimen to a species level until more material from that area is available for study.
