Fore wing with vein cu-a joining cell 1M at basal 1/3, vein 2r joining cell 2Rs at apical 3/8, and cell 2Rs as long as cell 1Rs; petiole of anal cell in the fore wing slightly shorter than vein 1r-m; petiole of anal cell in the hind wing as long as 1/2 times the length of vein cu-a. Lancet with 22 serrulae ( Fig. 37 ), middle serrulae strongly protruding and middle serrulae each with 1 to 2 proximal and 5 to 6 distal teeth, subbasal teeth small, annular spine bands not broad, with sparse pilosity; 8 th to 10 th serrulae as shown in Fig. 38 .

Male. Body length 9.5 mm ( Fig. 29 ); body color and structure similar to female as follows: apices of all coxae, all trochanters, fore and middle femora, except outer sides with black maculae, fore and middle tibiae and tarsi entirely, basal 1/3 and ventral side of the hind femur, subbasal 1/2 of dorsal side of hind tibia, posterior margin of abdominal sternites 2 to 6 with broad, white maculae; anterior margin of clypeus shallowly incised to approximately 1/3 length, lateral corner subquadrate ( Fig. 35 ); antenna as shown in Fig. 36 ; metascutellum entirely black; base of the outer surface of the middle and hind coxae without white macula; harpe approximately 2.2 times longer than broad, weakly narrowed toward the apex ( Fig. 39 ); valviceps approximately 1.6 times longer than broad, penis valve as shown in Fig. 40 .

Etymology. The species is named after Mr. Jian-Hua Huang.

Remarks. The color pattern of the antenna and legs shows that the new species is a member of the depressina - subgroup of the sanguinolenta- group. The new species is similar to M. depressina Wei, 2005 from China. Compared with M. depressina , M. huangi is characterized by lateral posterior of postocellar area black; posterior margin of pronotum with narrow white band; prescutum entirely black; center of mesoscutellum with white macula; mesoscutellar appendage entirely black; lateral area of metascutellum with white macula; lateral corner of abdominal tergite 1 black; posterior and lateral corners of abdominal tergite 2 with unconnected white macula; anterior margin of clypeus roundish and incised to approximately 1/2 of its length; apical 2/5 of the hind femur white; subbasal 2/ 5 in the dorsal side of the hind tibia white; anal cell in the fore wing with petiole slightly shorter than vein 1r-m, anal cell in the hind wing with petiole approximately 1/2 times the length of vein cu-a. In M. depressina , lateral posterior postocellar area with small white macula; posterior margin and lateral margin of prenotum with broad white band; prescutum with clearly long and white macula; mesoscutellum entirely white; mesoscutellar appendage largely white; metascutellum entirely white; lateral corner of abdominal segment 1 with clearly white macula; posterior and lateral corner of abdominal tergite 2 with connected white macula; anterior margin of clypeus arcuate; apical 1/3 of hind femur white; subbasal 1/2 of the dorsal side of hind tibia white; anal cell in the fore wing with a middle petiole and slightly longer than vein 1r-m, anal cell in the hind wing approximately 1/2 times slightly longer than 1/2 vein cu-a.
