Hladilovi leg. (as D. dalmatina in Schimmel & Platia 2008 ) ( PCRS ). New material. MONTENEGRO : Njeguši vill. env., 1000–1200 m ( 42°25'30.09"N , 18°50'45.00"E ), 7.– 10. V.2014, 1 ♂, fagetum, Jan Habarta leg. ( PCJM ). Diagnosis. Dima marvani is a medium-sized species (body length: 9.5–12.8 mm ) with an elongate body shape, relatively long antennae (surpassing hind angles by 3.5–4.5 segments), shiny pronotum with sides with the short semi-erect setae along the whole length, elytra with short dense decumbent pubescence, and the elytral interstices matt, microreticulated. This species can be easily distinguished from D . elateroides by the denser body pubescence and matt elytra ( Figs 22–24 , 62–65 ), from D . moraveci by the more elongate body shape and microreticulated surface of elytra ( Fig. 66 ), and from D . pelikani sp. nov. by the shiny pronotum ( Figs 144, 151 ). Dima marvani is very like D. dalmatina ( Figs 14–19 , 62–65 ). The specimens from the type locality (Lovčen Mts.) differ from the typical D. dalmatina by the less distinct keel between the frons and clypeus, longer antennae in males (more than 60% of the body length), longer pronotum (1.3 times wider than long), pronotal pubescence sparser, near sides of pronotum directed towards sides ( Figs 62–63 ), and apical lobe of paramera longer ( Fig. 198 ). Intraspecific variability. The specimens from Rumija Mts. have a darker body, almost no keel between the frons and clypeus, slightly longer antennae, and more convex and shorter pronotum than the specimens from Lovčen Mts. ( Figs 64–65 ). Similar variability in Rumija Mts. is known also for the very similar D. dalmatina ( Figs 18–19 ). More material of both species from different collecting sites is needed for further conclusions. Distribution. Montenegro (Lovčen Mts., Rumija Mts.; Fig. 243 ).
