Distribution. Myanmar (Kayah State).

Etymology. This new species is cordially dedicated to Prof. Takahiro Asami, Shinshu University, Japan.

Diagnosis. Distinguished by the position of the middle setae of the labrum located directly near the margin, coppery black elytra, and the elytral maculation comprising a marginal dot at mid length of elytra, which is larger than the central dot and apart from it, and a small apical dot without apical extension.

Description. Size: Total length (without labrum) 8.9–10.8 mm (mean = 9.7 mm, n = 13). Head: Shiny coppery, with greenish reflections at orbital furrows and clypeus, genae bluish black; surface smooth, glabrous, with two setigerous punctures next to each of the eyes in front and at the center; strong longitudinal striae on orbital plates longitudinal waved on frons, vertex and behind on neck; genae fine longitudinally striated. Ratio of width of head to width of elytra, mean = 0.9. Labrum (male Fig. 16 , female Fig. 17 ) distinctly wider than long, ratio of length to width, mean = 0.8; with four setae located near the margin, setal pits of the same color than remainder of the labrum, with five teeth in front; middle part with three teeth extracted (less in males than in females), middle tooth extracted in males and females; color brownish, darker at base in both sexes and darker at apex in females. Mandibles with four teeth darkened, small area of base brownish, Labial and maxillary palpi testaceous, the last segment shiny black; basal segment of labial palpi with long erected white setae. Antennae slender, reaching the elytral third in the males, shorter in the females; antennomeres one to four black, with metallic luster; scape with one apical seta, the other three antennomeres almost glabrous; antennomeres five to eleven black, dull, finely and evenly pubescent. Thorax: Pronotum as wide as long (ratio of length to width, mean = 1.0), sides somewhat rounded between the transversal constrictions; glabrous, transversely waved on disc; color shiny coppery, greenish at the transverse constrictions, bluish green at margins; sternae and episternae glabrous, bluish black; mesepisternum of females with a deep triangular impression in the center. Elytra: ( Fig. 18–20 ) parallel-sided, color shiny brownish black above, greenish to bluish at the margin; elytral testaceous maculation consists of a small humeral dot (absent in females), a small marginal and a tiny or absent central dot, and a small roundish or triangular apical dot. Surface with dense and evenly spaced punctures, in short rows near the suture; apical border distinctly rounded and restricted towards middle suture, with a tiny sutural spine. Epipleurae black. Ventral aspect: Venter glabrous, bluish black, marginally greenish; trochanters glabrous, coxae, femora, tibia and tarsi with white setae; trochanters, apical part of femora (knee) and tibiae brownish, latter darkened towards apex, remainder shiny metallic greenish. Aedeagus: ( Fig. 21 ) on left lateral view slender, with a tiny pointed tip at apex (total length 2.6mm).
