(mm). Male (n = 4), pronotum length × width: 2.4-2.6 × 3.2-3.4, tegmina length: 10.5-11.5, body length: 10.4-10.8, overall length: 13.1-13.4. Female (n = 2), pronotum length × width: 2.5-2.7 × 3.4-3.6, tegmina length: 11.1-11.5, body length: 10.6-10.7, overall length: 13.4-13.7.

Description.

Male. Coloration. Body, head and face yellowish brown (Fig. 8A, B ). Interocular space with a wider brown transverse band. Ocellar spots big and white (Fig. 8F ). Antennal base pale yellow, other segments yellowish brown to brown. Maxillary palpi yellowish brown (Fig. 8J ). Pronotal disc yellowish brown with dark brown spots and maculae, and two lateral borders pale linen-colored and transparent (Fig. 8E ). Legs yellowish brown, with black spots at the base of the tibial spines. Tegmina pale yellowish brown, hind wings transparent, brownish grey (Fig. 8G, H ). 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 round black spot on the inside of the longitudinal lines. Cerci yellowish brown (Fig. 8L ). Styli yellowish white (Fig. 8N ).

Head. Vertex slightly exposed, interocellar distance wider than the distance between eyes, narrower than the distance between antennal sockets (Fig. 8F ). Pronotum subelliptical, broader than long, anterior and posterior margins nearly straight, and postero-lateral angle blunt and round; disc with symmetrical irregular spots and maculae (Fig. 8E ). Fifth maxillary palpus expanded, third and fourth maxillary palpi both longer than fifth maxillary palpus (Fig. 8J ). Tegmina and hind wings. Tegmina and hind wings fully developed, both extending beyond the end of abdomen (Fig. 8A, B ). Tegmina with M and CuA radial, M straight with six complete branches. Hind wings with ScP and RA expanded at apex, M simple, without branches; CuA with four complete branches (Fig. 8G, H ). Legs. Anteroventral margin of front femur Type B2 (Fig. 8K ). 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 tuft of bristles in the middle (Fig. 8I ). Supra-anal plate symmetrical, anterior margin straight and truncate, posterior margin produced, slightly concave in the middle. Paraprocts simple, similar, and flaky. Cerci long, setae on the ventral surface (Fig. 8L ). Subgenital plate nearly symmetrical, anterior margin slightly concave in the middle. Styli similar, slender, conical; interstylar margin irregular produced (Fig. 8N ). Left phallomere complex, irregular bone-shaped, with a long spine and three small spines (Fig. 8M ). Median phallomere slender rod-shaped, with a forceps-shaped apex. Accessory sclerite I arched; accessory sclerite II with a transverse rod with denticulate (Fig. 8N ). Hook phallomere on the right side, apex slightly curved inwards with a short spine (Fig. 8O ).

Female. Similar to the male.

Diagnosis.

This species is similar to M. transversa He & Wang, 2021 in general appearance, but can be differentiated from the latter by the following characters: 1) left phallomere with a long spine; the latter with three long spine-like processes; 2) median phallomere with a forceps-shaped apex; while in the latter, median phallomere apex with a curved spine.

Etymology.

The specific name forcipatus, derived from Latin, refers to the median phallomere with a forceps-shaped apex.

Distribution.

China (Guangdong).
