Diagnosis. Dima arndti is 11.8–14.3 mm long, moderately shiny with pronotum densely punctate (Fig. 119) with short decumbent pubescence, longer only at hind angles, and elytra shiny, covered with sparse short pubescence (Figs 1–4). It differs from the similar D. parnonensis Schimmel & Platia, 2008 (Figs 81–84) in having a less shiny body, relatively wider pronotum, widest at 2/3, with sides abruptly constricted before posterior angles (pronotum widest after middle, with sides almost evenly rounded in D. parnonensis; Figs 119, 149), and the apical lobe of paramera elongate, with inner apical part of paramera almost straight (the apical lobe of paramera shorter, more robust, with inner apical part more curved in D. parnonensis; Figs 172–173, 204–205). The sclerotized spines of bursa copulatrix as in Fig. 222.
Intraspecific variability. Body coloration is variable, dark brown to light brown (Figs 1–4).
Distribution. Greece (Peloponnese: Taygetos Mts.; Fig. 246).
Remark. There is a single male specimen of Dima sp. collected in Crete (Fig. 5), with the following data: "Crete [Kreta Is.], Theriso, VI.1985, 1 ♂, Dr. P. Schurmann leg." (as D. hladilorum Schimmel, 1987 in Schimmel & Platia 2008) (PCGP). This specimen is morphologically like D. arndti and D. parnonensis from the Peloponnese, but it has shorter antennae surpassing the posterior angles of pronotum by about three antennomeres, thicker antennal segments, longer pronotum, more emarginate basal part of scutellum, and the inner apical part of paramera only slightly curved (Figs 5, 174). This 30-year-old record must be confirmed by new material in Crete, and more specimens are needed for further investigation. Therefore, we herein refrain from making any taxonomic conclusions.
