LSID: urn:lsid:zoobank.org:act:36FED1E2-F71D-46C2-9BB9-44C4B6440981 .

Etymology: The new species is dedicated to Wolfgang Barries (Vienna, Austria), with my deepest gratitude and respect.

Diagnosis: Body ( Fig. 1) rather robust, 2.2× as long as wide, moderately convex, blackish-violet with indistinct bronzy-greenish reflection on pronotum, elytra with 3 pairs of rather small bluish-green spots – irregularly rounded on humeri, slightly obliquely transverse near mid-length and at the level of posterior ⅙, elytral apex slightly brightened. Surface shiny, without shagreen except of finely microreticulated silky lustrous elytral spots and hypomera. Body length 3.52 mm, width 1.60 mm.

Description: Male. Head large, enlarged anteriorly, distinctly wider than anterior margin of pronotum, frontovertex finely arcuately concave, oculofrontal margins widely obtuse-angled, rounded, eyes roundly slightly irregularly projected beyond head outline. Clypeus turned back, transversely triangular with anterior margin very finely arcuately emarginated. Frons strongly widened posteriorly, behind clypeus, with pair of deep round fovea laterally continued as less deep transverse grooves behind antennal cavities, and with large irregularly oval longitudinal fovea medially. Surface with rather large but very superficial and sparse punctures, anteriorly nearly indistinct. Antennae serrate from antennomere 5 which is distinctly longitudinal, antennomere 6 nearly equilateral, following antennomeres moderately transverse.

Pronotum 2.4× as wide as long, widest just behind middle.Anterior margin slightly bisinuate, edged with thin groove widely interrupted medially, sides widely slightly irregularly arcuate, weakly serrate, lateral margins with thin elevation continued along posterior margin of pronotum, the latter strongly bisinuate with wide medial lobe slightly arcuately emarginated opposite scutellum. Pronotum with wide transversal elevation on disk, flattened along sides and slightly adpressed along posterior margin. Surface with rather big superficial irregular punctures, medially sometimes fused into twisting longitudinal wrinkles.

Scutellum nearly equilaterally triangular.

Elytra approximately 1.7× as long as wide, slightly wider than pronotum, widest near humeral tubercles, slightly and nearly rectilinearly narrowed towards posterior ⅖–⅓, then stronger, first obsoletely weakly arcuately then slightly sinuately narrowed to slightly irregularly arcuate apex. Elytra convex, narrowly flattened along sides behind humeri in anterior ⅓, transversely adpressed medially of humeral tubercles. Elytral sides weakly to obsoletely serrate, fringed with thin groove almost reaching elytral apex. Surface with small distinct irregular hyphen-shaped punctures slightly smoothed posteriorly.

Hypomera without distinct sculpture apart from microreticulation, prosternal process with rather rough transversal punctures. Metasternum and sides of 1 st visible ventrite with thin long oblique wrinkles somewhere connected in a net, medially and backwards divided into short transversal punctures, smoothed posteriorly, and in anal ventrite nearly indistinct.

Anal ventrite nearly straightly truncate, distally with widely rounded angles.

Male genitalia as in Fig. 2.

Female. Unknown.
