Labrum and mandible black.Antenna slender and extending almost to the middle of the elytra, pale yellow and only terminal antennomere partly brownish ( Fig. 22b, 23A). Third antennomere slightly longer than second; ratio length of second to third antennomere 0.75–1.00 (mean 0.88); ratio length of third to fourth antennomere 0.44–0.50 (mean 0.47; Fig.23B).  Thorax.Pronotum very finely punctuated, entirely pale yellow, parallel-sided and a bit widened posteriorly. Pronotal width 1.40–1.80 mm(mean 1.60 mm), ratio length to width 0.56–0.58 (mean 0.57). Scutellum, meso- and metathorax black. Elytron finely punctuated, black with a broad yellowish transverse band beyond the middle and brown-reddish band in the apical part ( Figs 22b, 23A). Elytral length 3.40–4.60 mm(mean 4.00 mm), maximal width of both elytra together 2.50–3.30 mm(mean 2.90 mm), ratio of maximal width of both elytra together to length of elytron 0.72–0.74 (mean 0.73). Foreleg yellow, mid and hindlegs blackish ( Fig. 22b).  Female genitalia.Spermatheca with small spherical nodulus with broad ridge, long and curved cornu ( Fig 23D). Bursa sclerites small and slender ( Fig. 23E).   Diagnosis.Elytral colouration of  M. flavofasciatais very characteristic by its broad black base, a small transverse yellow band around the middle, followed by a broader transverse black band that is reaching the outer elytral margin, and a reddish elytral apex. Most similar in elytral colouration is  M. orientalis, but with brown-reddish elytra with broad yellowish transverse band in the middle, bounded above and below by a narrow black band, and another narrow black band is placed across the basal margin ( Figs 19b, 20A, 22b, 23A). The genitalic characters of both species are very different in both sexes ( Figs 20C–E, 23C–E).   Distribution.Known from East-India, Myanmarand Thailandto the Malayan Peninsula ( Fig. 21). 5213732549 1885-08 MCGD, MCZH Jacoby Myanmar Bhamoo Bhamoo Fea 14 153 2 5213732420 1885-08 MCGD, MCZH Myanmar 15 154 Bhamo Fea 14 153 1 syntype 5213732307 BMNH Fry Coll. & Doherty India 26.2 Palkai 1243 92.933334 15 154 2 Assam 5213732888 NHRS Baker Malaysia 5.25 Island 1305 100.48333 15 154 1 Pulau Pinang 5213732587 1913-11 BMNH G.
