Figs 1–31 . Description. Length— 9.7–11.9 mm (x = 11.1 mm ; n = 5), greatest depth at abdomen - 3.6–3.8 mm . Dorsum ( Fig. 1 ) shining, with dark bronzy-greenish luster; antennae and legs reddish-brown; underside brownish with metallic luster. Vertex and frons ( Fig. 3 ) covered with large and dense punctures with some interstices wrinkled. Pronotum ( Fig. 9 ) covered with punctures of different size, dense, not larger than those on head. Scutellary shield ( Fig. 14 ) covered with small and sparse punctures. Elytral punctation ( Figs 15, 16 ) larger than pronotal, setae sparse at disc and much denser at lateral sides and apical portion. Apical third of tibiae covered with dense and long yellowish setae. Aedeagus ( Figs 29–31 ) long and broad, weakly depressed dorsoventrally, basal hood constitutes the half of aedeagal lenght, main body of penis gradually widened towards apex, apex nearly straight with well-developed, sharp triangular tip; in lateral view ( Fig. 30 ) slightly curved, apical half with equal width, apex thin, apical tip acute. Spermatheca ( Fig. 28 ) small, c-shaped, strongly curved and thick, proximal and distal parts of spermathecal capsule not delimited. Etymology.
