Diagnosis

Coryphe narrower than in M. fletcheri sp.n., face also narrower, with sharper carinae. Fuscous and dark fuscous, with rufous tint. Posterior and lateral parts of coryphe whitish, middle part with infuscation in the form of drop-shaped spot, dissected longitudinally by thin pale line. Acrometope blackened, 3 dark prominences arising from it onto callose part of eumetope. Middle part of anterior carina of coryphe blackened. Eumetope dark fuscous, with pale fuscous carinae and apical callosity. Clypeus pale fuscous. Posterior part of supraocular area pale fuscous, anterior part dark fuscous, preocular area, gena and lorum also dark fuscous. Carinae of pronotum and its margins pale, interspaces infuscate, but lightened areas on postocular carinae and posterior margin of pronotum merging dorsally, leaving only 2 dark spots on disc. Scutellum of mesonotum dark fuscous, including carinae; anterior halves of posterior margins of scutellum beginning from tegulae slightly paler. Tegulae fuscous, with whitish upper margins. Lateral parts of thorax dark fuscous, legs fuscous. Fore and middle femora slightly infuscate before apex, tibiae slightly darker than femora. Hind femur with lightened carinae, tibia with lightened apical part; ends of teeth blackened. Fore wing with distinct dark fuscous cross band, somewhat arcuately projecting forward in folded wings, running from middle of costal margin to middle of clavus; in costal area, cross band excised in the middle by pale spot. Wing base with dark, irregular, eroded spot, extending over clavus in parallel to scutellar margin, and on corium, stretching over mediocubital area distally to basal cell along entire length of the latter. Basal part of extravenal pterostigma entire, opaque, white; dark spot situated behind it, occupying part of extravenal pterostigma and part of stigmal cell. Veins outside dark spots pale fuscous, with dark granules; on membrane, transverse ladder of veins running from pterostigma (vein ir) to mcu and basal adjacent part of CuA1. Cross veins in the middle of membrane also infuscate, as well as isolated sections of longitudinal veins at margin of memberane and between rows of cross veins M and CuA1; posterior cell of membrane slightly infuscate. On clavus, portions of posterior claval area outside infuscations whitish infumated. Abdomen dark fuscous, with pale posterior margins of sclerites. Female length 5.9 mm. (Emeljanov 2000)
