(mm). Male (n = 6), pronotum length × width: 2.4-2.7 × 3.4-3.7, tegmina length: 11.8-12.3, body length: 8.8-10.3, overall length: 13.2-13.7. Female (n = 4), pronotum length × width: 2.4-2.9 × 3.2-3.9, tegmina length: 11.2-11.6, body length: 10.9-12.8, overall length: 13.2-14.0.

Description.

Male. Coloration. Body pale yellow (Fig. 3A, B ). 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 ). Maxillary palpi pale brown (Fig. 3J ). Pronotal disc pale yellowish brown with reddish tan stripes, and two lateral borders pale linen-colored and transparent (Fig. 3F ). Tegmina pale yellowish brown, hind wings brownish grey (Fig. 3G, H ). 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 ). Cerci yellowish brown to pale brown (Fig. 3L ). Styli yellowish white (Fig. 3N ).

Head. Vertex slightly exposed, interocellar distance slightly wider than the distance between eyes, narrower than the distance between antennal sockets (Fig. 3F ). Fifth maxillary palpus expanded, third and fourth maxillary palpi nearly equal in length, both longer than fifth maxillary palpus (Fig. 3J ). 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 ). Tegmina and hind wings. Tegmina and hind wings fully developed, both extending beyond the end of abdomen (Fig. 3A, B ). 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 ). Legs. Anteroventral margin of front femur Type B3 (Fig. 3K ). 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 ). Supra-anal plate symmetrical, middle posterior margin slightly concave. Paraprocts simple, similar, and flaky (Fig. 3L ). Cerci long, with setae on the ventral surface (Fig. 3L ). Styli similar, foot-shaped (Fig. 3N ). Subgenital plate nearly symmetrical, posterior margin truncate (Fig. 3N ). Left phallomere small, irregular bone-shaped, with a long spine (Fig. 3M ). 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 ). Hook phallomere on the right side, apex curved inwards with a short spine (Fig. 3O ).

Female. Similar to the male (Fig. 3C, D ).

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).
