Description

Length: 4.5–11 mm (126 specimens)

Head including eyes broader than apex of pronotum; densely punctate; antennae and club dark, base more or less reddish.

Pronotum slightly longer than broad (length:width ratio 1.08); lateral margin strongly sinuate, rarely subparallel; with relatively large punctures; color variable from greenishblue to blue or green; pubescence long, dark.

Elytral ground color orange to red, reduced to three spots or fasciae, therefore elytra mainly blue to blue­green or elytral ground color in the middle with a narrow, white to yellow­orange or brownish fascia (= ab. dregei Chevrolat, 1874) or basal part of orange ground color reduced to a semicircular spot (= ab. semiannulatus Corporaal, 1948) or basal part of elytral ground color crescent­shaped, with a small part at the utmost margin, in the middle with a more narrow, white to yellow­orange or brownish fascia (= ab. semilunatus Corporaal, 1948).

Elytra two and a half times as long as broad (length:width ratio 2.66), slightly constricted towards the middle; suture behind humeral spot slightly protruding; color beside suture glossy greenish, towards elytral margin glossy dark bluish. Punctures in regular rows, large, becoming weaker to obscured towards apex of elytra; diameter of punctures mostly larger than intervals, at base nearly equal in size as intervals; apex slightly bevelled; sutural angle mostly acute, sometimes with small tooth; pubescence dark, hairs shorter and more sparse than on head and pronotum.

Legs bluish; hind tibiae straight; with long, dark hairs (mostly at top), but also with short, white hairs.

Ventral surface dark bluish, green or combination of both; abdominal sternites with brown margin; thorax with dense, white pubescence; abdomen with more sparsely white pubescence.

Aedeagus, pygidium and male sternum VIII, see figs. 1–4.
