Paratype:  “ VIETNAM, Khanh Hoa prov., Khanh Vinh distr. , ~ 3 km above felling, 12°13.422' N, 108°45.535' E, alt. 916 m, at light, 4.6.2012, A.M. Prokofiev leg. | [paratype label]” ( CAP) GoogleMaps .

Description (holotype): Length 8.5 mm, greatest width 4.5 mm. Reddish-brown above, pronotum with strong dark-green tint and broad yellowish side margins; apical protuberances of elytra with oblong blackish marks descending toward side border; sterna and pygidium testaceous, abdomen much darker, reddish-brown; legs testaceous, except most parts of protibia and upper and inner parts of meso- and metatibia, which are metallic green-brown, tarsi reddish-brown to blackish, hind tarsi darker; antennae reddish-brown, club darker; pilosity pale.

Clypeus nearly trapezoidal, with sides convergent anteriad, anterior angles broadly rounded, not distinct; anterior margin straight,weakly raised,narrow in frontal view. Outer part along outer margin distinctly impressed, finely punctured, convex central and basal parts of clypeus coarsely, rugosely punctate. Fronto-clypeal suture distinct. Inner margin of eye with fine marginal line, with a single erect seta inserted before its mid-length on each side (perhaps other setae worn off). Eyes somewhat bulging. Anterior half of frons rugosely punctate, slightly impressed at center, punctures becoming smaller and much sparser toward vertex. Pronotum 1.9 times broader than long, sides almost parallel in basal half, distinctly convergent in anterior half; anterior angles acute; posterior angles obtuse, rounded. Anterior margin of pronotum with complete marginal line, concave; posterior margin of pronotum strongly convex in middle third, straightened in outer thirds, basis with complete marginal line. Sides of pronotum with few long erect distant hairs. Pronotum regularly and distinctly, moderately dense punctured, spaces between punctures on disc more or less equal with their diameter, punctures becoming smaller toward the margins. Scutellum subtriangular with apex bluntly pointed, irregularly punctured; punctures similar to those on the disc of pronotum. Elytra with distinct punctate rows having deep simple punctures and slightly convex interspaces; second interspace with irregular punctation narrowed into a single row in posteri- ormost quarter, 4 th, 6 th and 8 th interspaces with a single row of punctures; punctures in even interspaces the same as in punctate rows; odd interspaces with minute somewhat irregular punctures. Sides of elytra with marginal line, with elytral epipleura thickened under humeral umbo, bearing short distant setae, longer and more closely spaced under humeral umbo. Pygidium weakly convex, rugosely punctate, with a double row of rather long erect hairs at apex.

Prosternal process well-developed, plough-shaped, bluntly pointed anteriorly, its ventral margin conspicuously sloping anteriad, posterior ventral angle with small but distinct anteriorly recurved tooth. Mesometasternal process indistinct. Sides of sterna somewhat rugosely punctate, with short and rather sparse adpressed hairs; disc of metasternum glabrous, impressed. Abdominal sternites coarsely punctured, punctures smaller and denser at upper sides, each sternite with a transverse row of well spaced rather long semierect setae, which are conspicuously longer on penultimate sternite; last visible sternite with similar setae along distal border.

Protibia bidentate, apical tooth long, basal tooth welldeveloped, inner spur attached at level of basal tooth. Last joint of fore tarsi thickened apically, indented at mid-length of its concave margin. Inner fore claw broadened, with lobes slightly divergent, lower lobe 2.5 times broader than upper at base, its ventral margin distinctly convex. Outer claw of middle tarsi cleft. Metatarsal joints distinctly thicker than pro- and mesotarsal joints. Hind tibiae fusiform. Long spur of hind tibiae evenly doublecurved, narrow but blunt at apex.

Aedeagus: Figs 44–46 View Figs 44–60 .

Variation: Punctation of pronotum somewhat coarser and punctation of scutellum denser and more regular in the second male; black apical marks on elytra indistinct and not covering apical protuberances in the paratype.

Female: unknown.

Differential diagnosis: Small size, color and punctation pattern of elytra make this new species look extremely similar to Anomala felicia ARROW, 1910 from Borneo, however, the well developed prosternal process places this species in the genus Mimela . The closest relatives appear to be the small Sundanian species M. discoidea BURMEISTER, 1844 , M. vethi OHAUS, 1913 and Mimela nana LANSBERGE, 1879 . The aedeagus of Mimela krasava is very different from those species in having apically somewhat raised and pointed parameres. Moreover, all known similar Mimela species from Malaysia, Sumatra and Java are more or less testaceous.

Distribution: So far known only from the Dalat Plateau, South Vietnam.

Etymology: The species epithet is derived from a Russian word meaning “beautiful”, to be used as noun in apposition.
