Etymology. This new species is cordially dedicated to one of its discoverers, Ms. Thanda Moe, Deputy Staff Officer, Perennial Crops Research and Development Center (Mawlamyine), Department of Agri- culture, Maynmar.

Diagnosis. Distinguished by the position of the middle setae of the labrum located far away from the margin, and the elytral maculation comprising a triangular or comma-shaped apical dot, which extends towards the elytral apex.

Description. Size: Total length (without labrum) 9.2–11.6 mm (mean = 10.2 mm, n = 8). Head: Shiny coppery, clypeus, frons, genae and short basal part of orbital furrow greenish; 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, irregular and 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. 2, female Fig. 3) distinctly wider than long, ratio of length to width, mean = 0.6; with four setae, the two middle ones with dark setal pits and located far away from the margin, three-dentate in the middle of front; color testaceous, margin and insertion of median two setae blackish. Mandibles with four teeth, darkened, base yellowish. Labial and maxillary palpi testaceous, the last segment metallic dark greenish; 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 coppery, greenish at the transverse constrictions, bluish at margins; sternae and episternae glabrous, black, with or without coppery or greenish hue; mesepisternum of females with a large pit in the upper half. Elytra: (Fig. 4–6) parallel-sided, color shiny coppery above, greenish to bluish at the margin; elytral testaceous maculation consists of a small humeral dot (absent in females), a small marginal dot and a much smaller or nearly extinct central, and a triangular or comma-shaped apical dot, which is extended towards the elytral apex. Surface with dense and evenly spaced punctures, in 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 testaceous, latter darkened towards apex, remainder shiny metallic greenish. Aedeagus: (Fig. 7) on left lateral view voluminous, tapering, with a straight, and pointed apex and two lateral ribs near the apex (total length 2.8mm).
