Diagnosis. The new species is similar to M. shennongjiana Wei & Zhao, 2011 from China. Compared with M. shennongjiana , the new species is characterized by labrum entirely and clypeus largely black, short parts white; clypeus half round, incised to 1/2 length of clypeus, lateral lobes narrow and long; 2 small, narrow maculae on posterior margin of postocellar area, not U-like; anterior corners of pronotum entirely black; tergites 6–9 entirely black, other tergites with distinct white maculae; subapical 1/2 of hind tibia with a long, white macula on dorsal side; middle serrulae of lancet each with 2 distal teeth, subbasal teeth large. In M. shennongjiana , labrum and clypeus almost entirely white, but basal margin of clypeus black; anterior margin subarc and incised to 1/3 length of clypeus, lateral corners slightly broad and short; 1 U-like white macula on posterior margin of postocellar area; anterior corners of pronotum with distinct, white maculae; all tergites with distinct, white maculae; apex of hind tibia with a small white macula on dorsal side, distinctly shorter than 1/2 length of hind tibia; middle serrulae of lancet each with 15–16 distal teeth, subbasal teeth minute.

Female. Body length 10.0 mm. Body black, except some white or reddish brown parts. The following parts white: base of the mandibles, a small triangular macula on apex of the labrum, 2 small maculae on posterior margin of the postocellar area, posterior corners of the pronotum, mesoscutellum, center of posttergite, narrow band on posterior margin of tergite 1, long triangular maculae on posterior corners of tergites 2–5, center of tergite 10, base and stripes of fore coxa on outer side, anterior side largely of fore femur, anterior sides of fore tibia and tarsus, base and outer side of middle coxa, apex of middle femur on anterior side, stripes on subapex of middle tibia on outer side, middle tarsomere except for apical margins with black maculae, an oval macula of hind coxa on outer side, hind trochanter, subapical 1/2 of hind tibia on dorsal side, small maculae on apex of metabasitarsus on dorsal side and dorsal sides of hind tarsomere 2–4. The following parts reddish brown: middle femur except for base with black maculae, apex with white maculae and outer side with black maculae, hind femur except apical margin with black maculae, ventral side of hind tibia except for apical margin with black maculae and basal 1/2 on dorsal side. Body hairs silver, setae on sheath black brown. Wings hyaline, vein C brown, stigma and other veins black brown ( Fig. 31 ).

Dorsal head less shiny, fron sparsely and shallowly punctured, interspaces between punctures with fine microsculptures; inner side of temple with small smooth area, almost without puncture ( Fig. 33 ); labrum and clypeus with shallow punctures, surface weakly coriaceous. Mesonotum less shiny, punctures on mesonotum minuter and shallower than punctures on head, not very dense, interspaces between punctures with fine microsculptures; mesoscutellum shiny, with large and shallow punctures, microsculptures indistinct; lateral sides of posttergite with shallow punctures; metascutellum with indistinct punctures, microsculptures fine. Mesepisternum densely punctured, upper 1/2 with slightly large punctures, lower 1/2 with slightly small punctures, interspaces between punctures narrow and with fine microsculpture; anepimeron not shiny, with dense wrinkles; anterior margin of katepimeron smooth and shiny, without puncture or microsculpture; center with indistinct punctures, microsculptures distinct; posterior area with some large and coarse punctures, microsculptures distinct; metepisternum dull, minutely and densely punctured; metepimeron less shiny, large area with distinct punctures, microsculptures indistinct ( Fig. 35 ). All abdominal tergites less shiny, lateral tergite 1 shallowly punctured, center almost smooth; other tergites with minute and shallow punctures. Surface of sheath coriaceous, with indistinct punctures and fine microsculptures. Hind coxa and outer side of hind femur shallowly punctured, not dense, microsculptures fine.

Labrum elevated, anterior margin truncated; clypeus weakly elevated and subquadrate, slightly broader than the distance between the lower corner of eyes; lateral sides distinctly convergent forwards, anterior margin half round and incised to 1/2 length of clypeus, lateral lobes narrow and long, apical margin slightly acute, lateral margins slightly paralleled ( Fig. 34 ); malar space 0.5 times the diameter of the middle ocellus; fron flat and not depressed, ocellus slightly higher than the top of the eyes in lateral view; middle fovea shallow but distinct; lateral foveae deep, furrow like; interocellar furrow distinct, postocellar furrow indistinct; POL: OOL: OCL = 5: 11: 9; postocellar area weakly elevated, 2 times broader than long, anterior 1/2 of lateral furrows narrow and shallow, posterior 1/2 of lateral furrows deep, divergent backwards; head narrowed behind eyes in dorsal view, occipital carina complete. Antenna lost. Mesoscutellum roundly elevated, without carina, higher than the top of the mesonotum in lateral view; posttergite with short middle carina; dorsal-posterior platform of mesepimeron equal to diameter of lateral ocellus; posterior corner of metepimeron subquadrate, without appendage; mesopleuron and metapleuron as shown in Fig. 35 ; the distance between cenchri 2.7 times breadth of a cenchrus. Hind tibia and tarsus lost. Ovipositor sheath shorter than middle femur, apical sheath as long as basal sheath, apical margin roundish in lateral view ( Fig. 36 ). Fore wing with vein cu-a joining cell 1M at basal 1/5, vein 2r joining cell 2Rs at apical 1/3, cell 2Rs as long as cell 1Rs; petiole of anal cell in the fore wing shorter than 1/2 times of vein 1r-m; petiole of anal cell in the hind wing 1/3 times length of vein cu-a. Lancet shortly lost ( Fig. 39 ), middle serrulae each with 1 proximal and 2 distal teeth, subbasal teeth large, distal teeth not more than 5, distance between serrulae 11–12 as broad as serrula 11, annular spine bands slightly broad, spine slightly dense; 8 th –10 th serrulae at base as shown in Fig. 40 .

Male. Body length 7.0 mm ( Fig. 32 ); body color and structure similar to female, except following white parts: anterior sides of fore and middle femora, anterior side of fore tibia, fore and middle tarsumere almost entirely, apical 1/2 of middle tibia on anterior side, small maculae on posterior corners of abdominal tergite 2; head of male in anterior view as Fig. 37 ; male antenna as shown in Fig. 38 ; fore wing with vein cu-a joining cell 1M at basal 1/4, vein 2r joining cell 2Rs at apical 1/5, petiole of anal cell in fore wing about 3/4 longer than vein 1r-m; petiole of anal cell in hind wing 1/3 times longer than vein cu-a; subgenital plate longer than broad, apical margin roundish, gonoforceps as shown in Fig. 41 ; penis valve as shown in Fig. 42 .

Holotype female, China, Ningxia, Mt. Liupan , 15 June 1996, Guo-Dong Ren leg. Paratype 1 male, the same message to holotype.
