surface finely, somewhat irregularly punctuated, with minor and moderately long, pale setae (with a few long, 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 rather obsolete setiferous punctures; surface finely microreticulated, weakly, greasily shining. Dorsal side of posterior tarsi with several fine punctures. Length: 7.0-8.2 mm. Male genitalia: Fig. 2. Specimens examined (males): [Hercegovina], Plasa-Pl[anina], [leg.] Grabowski; [Hercegovina], Sandzsak, Korita, Akad. Balk. Exp., [leg.] Csiki, 1917. VII. 9. Omaloplia lonae differs from O. nigromarginata by the following external features. Surface of the head and pronotum is almost dull, the elytra barely nacreous, preferably greasily shining and, first of all, lateral margin of the elytra distinctly sinuate. Surface of the head, pronotum and elytra of O. nigromarginata is slightly nacreous, lateral margin of the elytra slightly sinuate, nearly rectilinear. Omaloplia lonae was previously described on the basis of a single female specimen. Omaloplia pontica sp. n. In general appearance extremely similar to Omaloplia ruricola (Fabricius, 1775). Body oval, convex, moderately broadening posteriorly; surface very finely microreticulated, barely nacreous; pitch-black in colour, elytra somewhat transparent, antennae, palpi and tarsi reddish brown. Dorsal and ventral surface with sparse pubescence, elytral disc apparently bare, pronotal and elytral margins fringed with long bristles. Surface of head coarsely, somewhat irregularly punctuated, with shallow setiferous punctures and obscure 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 obscure 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 present, reaching outer apical angle. Intervals weakly convex (odd intervals a little more raised, therefore, apparently narrower than even ones); surface strongly, somewhat irregularly punctuated, with a few minor pale setae (longer setae around shoulders and scutellum as well as along suture are broken). Wings normally developed. Scutellum triangular, rounded apically. Pygidium strongly, rather sparsely, somewhat irregularly punctuated, with somewhat obsolete setiferous punctures; surface very finely microreticulated, weakly, greasily shining. Dorsal side of posterior tarsi with several fine punctures. Length: 7.5 mm. Male genitalia: Fig. 3. Holotype (male): [Turkey], Brussa, 1870., leg. Pavel. The type is deposited in the Department of Zoology of the Hungarian Natural History Museum, Budapest. In external features Omaloplia pontica sp. n. is essentially the same as O. ruricola. The only distinguishing character is the form of the male genitalia.
