Diagnosis. Distinguished by the combination of laterally darkened labrum, transparent brownish elytral apex, long antennae, and black venter.

Etymology. This new species is dedicated to Peter Schüle for his assistance during these studies.

Description. Size: Total length (without labrum) 6.7 mm- 7.6 mm, (mean= 7.2 mm, n=5). Head: Shining greenish black. Mandibles yellowish, brownish distally in female, teeth brownish marginally. Labrum (male Fig. 229 , female Fig. 230 ) as wide as long, yellowish, lateral margins dark brown, with six apical teeth and one lateral tooth. Labial and maxillary palpi yellowish. Antennae lanceolate, extending posteriorally behind elytral shoulders in female, somewhat longer in the male, scape with a single apical bristle, antennomeres 2 to 5 glabrous, antennomeres 6 to 11 finely and evenly pubescent; scape yellowish above, black on underside, all the other antennal segments blackish. Clypeus glabrous. Frons smooth, with a transverse furrow in the posterior part of the orbital plates. Thorax: Pronotum shining greenish black, as long as wide, barely more constricted in front than at back, transverse furrows strong, middle line and lateral lines nearly obsolete, middle line with several transverse short branches. Elytra: Shining black, with basal and apical humps, distinctly punctate in front, nearly absent in apical half ( Fig. 225 ). Apex with angular lateral and sutural tooth, recurved between, somewhat transparent brownish, suture yellowish. Maculation yellow, composed of a humeral lunule, basal dot, and central dot which is acutely angled outwards toward the front ( Figs. 226, 227 ). Ventral aspect: Venter black. Legs of males yellowish, tibiae and tarsomeres somewhat darkened distally, femora darkened in distal half, legs of females somewhat darker.
