Distribution. Myanmar (Magway Region).

Etymology. This new species is cordially dedicated to Prof. Teiji Sota, Kyoto University, Japan.

Diagnosis. Distinguished by the position of the middle setae of the labrum located directly near the margin, 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 roundish apical dot with apical extension.

Description. Size: Total length (without labrum) 9.3–12.2 mm (mean = 10.4 mm, n = 13). Head: Dark coppery, with greenish reflections; surface smooth, glabrous, with two setigerous punctures next to each of the eyes in front and at the center; strong longitudinal striae on frons and orbital plates, transversely waved on vertex and behind on neck; genae fine longitudinally striated. Ratio of width of head to width of elytra, mean = 0.9. Labrum (male Fig. 9 , female Fig. 10 ) distinctly wider than long, ratio of length to width, mean = 0.7; 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), and the outer teeth acute angled in males, all three teeth acute angled in females; color testaceous, margin and insertion of median two setae a little darker. Mandibles with four teeth darkened, base yellowish, 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 dark, with metallic luster; scape with one apical seta, the other three antennomeres almost glabrous; antennomeres five to eleven dark brown, 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 dark coppery, greenish at the transverse constrictions, bluish green at margins; sternae and episternae glabrous, coppery or greenish black; mesepisternum of females with a large triangular notch in the upper half. Elytra: ( Fig. 11–13 ) parallel-sided, color dark coppery above, greenish to bluish at the margin; elytral testaceous maculation consists of a small humeral dot (absent in females), a small marginal and a much smaller central dot, and a roundish apical dot, which shows a short extension towards the elytral apex. Surface with dense and evenly spaced punctures, in short rows on the disc; 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 testaceous, latter darkened towards apex, remainder shiny metallic greenish. Aedeagus: ( Fig. 14 ) on left lateral view slender, with a tiny pointed tip at apex (total length 2.9mm).
