Surface of head coarsely, somewhat irregularly punctuated, with shallow setiferous punctures and pale setae. Clypeus transverse quadrangular, narrowing anteriorly, with upturned margins; anterior clypeal margin almost rectilinear; anterior angles broadly rounded. Pronotum convex, transverse quadrangular, arcuately narrowing anteriorly; surface strongly, somewhat irregularly punctuated, with setiferous punctures and pale setae; margins finely bordered; posterior angles obtusely rounded. Elytra convex, moderately broadening posteriorly, truncated apically. Humeral callus weakly prominent, preapical callus indistinct. Lateral margin (in lateral view) nearly rectilinear, only slightly sinuate. Epipleural ridge absent. Intervals weakly convex (odd intervals a little more raised, therefore, apparently narrower than even ones); surface finely, somewhat irregularly punctuated, with minor and moderately long, obscure setae (with a few long, obscure or pale setae around shoulders and scutellum as well as along suture). Wings normally developed. Scutellum triangular, rounded apically. Pygidium strongly, densely, somewhat irregularly punctuated, with somewhat obsolete setiferous punctures; surface apparently polished (with extremely fine, vague microreticulation - for the best part along sides only), brightly shining. Dorsal side of posterior tarsi without punctures. Length: 6.6 mm. Male genitalia: Fig. 5. Holotype (male): leg. T. Palm, Gr[eece]: Kos, Kefatos, 21/5 79. The type is deposited in the Department of Zoology of the Hungarian Natural History Museum, Budapest. In external features the new species differs from the similar Acarina spireae by the brightly shining pygidial surface apparently polished. Pygidial surface of the latter species is very finely microreticulated, weakly, a little (or more) greasily shining. The following catalogue includes all Omaloplia and Acarina species described. There is a species that I have not be able to recognize on the basis of the original description. Omaloplia arnoldii (Medvedev, 1952) was compared to Omaloplia nigromarginata (Herbst, 1785) (Homaloplia alternata: Medvedev, 1952) and it is probable that the two species are identical. The names Omaloplia sericea and Omaloplia nigra were originally validated by Burmeister (1855) as absolute synonyms and have never been treated as distinct species. These are objective synonyms of Melolontha ruricola and Homaloplia transsylvanica, respectivelyThe names Homaloplia setosa, Homaloplia subsinuata, Homaloplia heydeni, Homaloplia taygetana and Homaloplia badeni were originally validated by Reitter (1887) as absolute synonyms and have never been treated Fig. 5.
