Description.
Male. Coloration. Body pale yellow (Fig. 3A, B View Figure 3 ). Head yellowish brown. Face pale yellow. Interocular space with a wide brown transverse band. Ocellar spots white, interocellar space with a brown band. Antennal base pale yellowish brown, other segments dark brown (Fig. 3E View Figure 3 ). Maxillary palpi pale brown (Fig. 3J View Figure 3 ). Pronotal disc pale yellowish brown with reddish tan stripes, and two lateral borders pale linen-colored and transparent (Fig. 3F View Figure 3 ). Tegmina pale yellowish brown, hind wings brownish grey (Fig. 3G, H View Figure 3 ). Legs faint yellow. Abdomen yellowish brown, with black stripes along lateral margins of sterna and reaching the end of abdomen; both sides of each abdominal sternum with one small black spot on the inside of the longitudinal lines (Fig. 3B View Figure 3 ). Cerci yellowish brown to pale brown (Fig. 3L View Figure 3 ). Styli yellowish white (Fig. 3N View Figure 3 ).
Head. Vertex slightly exposed, interocellar distance slightly wider than the distance between eyes, narrower than the distance between antennal sockets (Fig. 3F View Figure 3 ). Fifth maxillary palpus expanded, third and fourth maxillary palpi nearly equal in length, both longer than fifth maxillary palpus (Fig. 3J View Figure 3 ). Pronotum subelliptical, broader than long, anterior and posterior margins nearly straight, and postero-lateral angle blunt and round; disc with symmetrical spots and stripes (Fig. 3E View Figure 3 ). Tegmina and hind wings. Tegmina and hind wings fully developed, both extending beyond the end of abdomen (Fig. 3A, B View Figure 3 ). Tegmina with M and CuA radial, M straight with three complete branches and one incomplete branch. Hind wings with ScP and RA expanded at apex, M simple, without branches; CuA with four complete branches (Fig. 3G, H View Figure 3 ). Legs. Anteroventral margin of front femur Type B3 (Fig. 3K View Figure 3 ). Four proximal tarsomeres with pulvilli. The pretarsi with arolium, tarsal claws symmetrical and specialized, with minute denticles on ventral margins.
Abdomen and genitalia. Eighth abdominal tergum specialized, with a heart-shaped transparent area and a tuft of bristles in the middle (Fig. 3I View Figure 3 ). Supra-anal plate symmetrical, middle posterior margin slightly concave. Paraprocts simple, similar, and flaky (Fig. 3L View Figure 3 ). Cerci long, with setae on the ventral surface (Fig. 3L View Figure 3 ). Styli similar, foot-shaped (Fig. 3N View Figure 3 ). Subgenital plate nearly symmetrical, posterior margin truncate (Fig. 3N View Figure 3 ). Left phallomere small, irregular bone-shaped, with a long spine (Fig. 3M View Figure 3 ). Median phallomere slender rod-shaped, with base curved, apex with a row of spines; accessory sclerite I arched, accessory sclerite II complicated with an inverted bell-shaped structure covered with fuzz (Fig. 3N View Figure 3 ). Hook phallomere on the right side, apex curved inwards with a short spine (Fig. 3O View Figure 3 ).
Female. Similar to the male (Fig. 3C, D View Figure 3 ).
Diagnosis.
This species is similar to M. speciosa Liu & Zhou, 2011 in general appearance, but can be differentiated from the latter by the following characters: 1) styli foot-shaped, while in the latter conical; 2) left phallomere with a long, curved spine, absent in the latter; and 3) accessory sclerite I without a brush-like structure at apex, while in the latter, accessory sclerite I with a brush-like structure at apex.
Etymology.
The specific epithet is derived from the Latin word pedatus, referring to the foot-shaped styli.
Distribution.
China (Yunnan).
