Celebia mindanaoensis View in CoL sp. nov.

Fig. 2C, D View Fig , 6G, H View Fig .

Differential diagnosis. C. mindanaoensis sp. nov. is frequently confused with C. philippinica Heller, 1921 by dealers and amateur entomologists, but after the study of the type specimens from SNSD ( Fig. 3 View Fig ) it was clear, that, based on the scally rounded markings on elytra, the new species is more similar to C. merrilli Schultze, 1919

( Fig. 4 View Fig ) and can be distinguished from it by the following characters: 1) Differences in the shape of the aedeagus ( Fig. 6I, J View Fig ); 2) elytra of C. mindanaoensis sp. nov. elongated, narrower, flattened in lateral view, while that in C. merrilli Schultze, 1919 more rounded, shorter and convex in lateral view; 3) body of C. mindanaoensis sp. nov. covered with light brown to orange scales, while that in C. merrilli Schultze, 1919 covered with glossy green, yellow and golden scales.

Dorsal view of habitus as in Fig. 2C View Fig .

Body black, elytra slightly glossy, with markings of light brown to orange round scales. Antenna dark brown.

Head subovate, with black longitudinal line without scales stretching from subbasal part of forehead to apex of rostrum; two black longitudinal lines without dorso-lateral apex; lateral portions of head around and behind eyes with pale, oval scales; dorsal and ventral parts densely covered with light brown scales; forehead slightly elevated dorsally, about two times as wide as medium-sized, convex eyes; rostrum (dorsal view) narrowing towards middle, widened to basal 1/3 and straightened to base; underside with short light hairs and longer hairs near labrum.

Pronotum subcylindrical, widest slightly before middle, wrinkled dorsally, with black longitudinal line in middle of disc and with two brown longitudinal lines at sides of black line; dorsolateral edge with brown longitudinal line; lateroventral portions with large patch of brown scale; basal margin covered with short brown hairs, slightly arched medially; contour of pronotum, if see laterally, gradually elevated from narrowest apical to widest basal margin.

Elytra subovate, somewhat straight from base to apical ¼ and then narrowed to apex, strongly rugose, covered with patches of brown to orange scales, patches arranged in five to seven longitudinal rows; suture with short brown hairs. Underside densely covered with round light brown scales, mixed with short light brown dense hairs.
