Description (holotype): Length 15.0 mm, greatest width 9.5 mm. Leaf-green, darker below, shining; pro-, meso- and metafemora with weak orange-brown tint; antennae reddish-brown, club much darker; pilosity pale.
Clypeus trapezoidal, with sides convergent anteriad, anterior angles broadly rounded, not distinct; anterior margin straight, weakly raised. Fronto-clypeal suture distinct. Inner margin of eye with indistinct marginal line, with a few erect setae. Clypeus coarsely, rugosely punctate, punctures similarly rugose and only slightly less dense in anteriormost part of frons, becoming sparser and finer posteriad; surface of frons and vertex with fine shagreenlike microsculpture. Pronotum twice broader than long, sides almost parallel in basal half, distinctly convergent in anterior half; anterior angles produced, sharp; posterior angles weakly obtuse, shortly rounded. Anterior margin of pronotum with marginal line in outer quarters, weakly bisinuate; posterior margin of pronotum convex, especially in the middle third, with indistinct traces of border in its outer thirds. Sides of pronotum with few long erect distant hairs. Pronotum, scutellum and elytra very finely and sparsely punctured, surface with fine shagreen-like microsculpture; punctate rows of elytra very weakly discernible. Posterior margin of scutellum ogival. Sides of elytra with marginal line, with elytral epipleura thickened, bearing rather long sparse setae. Pygidium strongly convex, sparsely but coarsely punctured (punctures being much denser but smaller along its base), punctures setigerous, with long erect hairs.
Prosternal process well-developed, plough-shaped, bluntly pointed anteriorly. Mesometasternal process very short, truncate. Sides of sterna coarsely, rugosely punctate and setose, with rather long but not dense adpressed hairs; disc of metasternum bare, glabrous, impressed. Sides of abdominal sternites with several rows of moderately long semi-erect hairs extending into a single transverse row along each sternite; last visible sternite glabrous with sparse hairs along distal border.
Protibia bidentate, teeth closely spaces, inner spur attached at level of basal tooth. Last joint of fore tarsi thickened, toothed just behind mid-length of its concave margin. Inner fore claw broadened, somewhat curved, with lobes slightly divergent, lower lobe about three times broader than upper at base. Outer claw of middle tarsi simple.
Aedeagus: Figs 47–50 View Figs 44–60 .
Female: Antennal club shorter. Pygidium less convex. Apical tooth of protibia much longer, broader, finger-like. Inner spur attached well behind basal tooth of protibia. Last joint of fore tarsi somewhat broadened distally, only slightly indented just behind middle of its concave margin; inner claw narrow, with lower lobe only 1.5 times broader than the upper one at base. Vaginal palpi triangular, densely setose.
Variations (both sexes): Length 14.0– 17.7 mm, greatest width 8.5–11.0 mm. Pro-, meso- and metafemora vary from green with slight orange-brown tint to completely orange-brown; sides of abdominal sternites sometimes with cupreous luster; apical margin of pygidium sometimes changes to orange-brown; 1 st joint of antennae (scapus) sometimes partially green. Density of punctation of frons and vertex highly variable, in extreme cases the anteriormost part of frons being rather sparsely though coarsely punctured and vertex being similarly punctured as pronotum. Pronotum 2.0–2.1 times as broad as long. Pygidium in some specimens more densely and coarsely punctured than in the others.
Differential diagnosis: Although resembling other leafgreen Mimela species like M. dehaani , M. glabra HOPE, 1841 etc. at first sight, the peculiar asymmetric aedeagus indicates a very close relationship to M. ignistriata , M. ngoclinhensis and M. campyloclados spec. nov. with very different coloration (metallic green or brownish with more or less present fiery red longitudinal stripes).
Distribution: So far known only from the Dalat Plateau, South Vietnam.
Etymology: The species epithet is referring to the type locality, Langbian (= Dalat) Plateau.
