Description:

Body shape. Length: 7.0- 7.5 mm, width: 3.3-3.7 mm; elongate oval; subparallel posteriorly; strongly convex. Color. Entirely yellowish brown; head between the eyes, some indistinct transverse patches on the disc of the pronotum and the entire abdomen in the male sex darker brown. Head. Clypeus trapezoid; anterior angles rounded; anterior margin reflexed; punctures moderately fine; frons densely and sometimes confluently punctured; punctures gradually finer and more sparse towards the vertex. Pronotum. Width 1.64 times length; in dorsal view lateral margin evenly curved and strongly converging towards the acute anterior angles; broadest somewhat behind the middle; posterior angles rounded; basal stria complete; the whole surface covered with moderately sized, umbilicate punctures. Elytra. With rather coarse and umbilicate punctures arranged in regular striae and intermixed irregular, sparse micropunctation; primary costae not elevated; subsutural, second and third interstice with one secondary row of punctures, the one of the subsutural interstice irregularly duplicated at its base; the three inner primary striae weakly sulcate at the apex; humeral protuberance indistinct. Pygidium. Densely covered with coarse, umbilicate punctures. Metasternum. Disc smooth with a longitudinal impression; lateral part with dense umbilicate punctures and indistinct, short setosity. Abdominal sternites. Densely, sometimes confluently punctured; with a transverse series of sparse short yellowish setae. Protibia. With a long acute lateral tooth and a long pointed terminal tooth which is strongly curved outwards; terminal articulated spine about 5 times as long as wide. Metatibia. 2.8 times as long as wide, weakly fusiform. Claws. External middle claw and internal front claw cleft; upper branch of the latter very small and spine-shaped; the lower branch much more broad and long, somewhat dilated at its inner margin; with a strongly pointed apex. Aedeagus. See figs 8, 9.

Diagnosis:

Anomala pumiloidespumiloides is very similar to A. pumilis but can easily be distinguished by the larger elongated body shape, the strongly rounded sides and the more coarse punctation of the pronotum and the less reflexed clypeus. Moreover, the hind tibiae are more fusiform in A. pumilispumilis and the parameres are distinctly longer ( Figs 10, 11 ).

Etymology: The species name is referring to the notable resemblance of the new species to A. pumilis .
