Measurements

(mm). Male (n = 7), pronotum length × width: 2.2-2.8 × 3.0-3.6, tegmina length: 11.3-12.2, body length: 10.1-11.1, overall length: 13.0-14.0. Female (n = 5), pronotum length × width: 2.2-2.8 × 3.0-3.6, tegmina length: 10.7-11.4, body length: 9.6-11.7, overall length: 12.9-13.7.

Description.

Male. Coloration. Body pale yellowish brown (Fig. 7A, B ). Head yellowish brown. Face pale yellow. Interocular space with a brown transverse band. Ocellar spots yellowish white (Fig. 7F ). Antennal base pale yellow, other segments yellowish brown. The third and fourth maxillary palpi yellowish brown, the fifth maxillary palpus brown (Fig. 7J ). Pronotal disc pale yellowish brown with reddish tan spots but without stripes, and two lateral borders pale linen-colored and transparent (Fig. 7E ). Legs faint yellow, with black spots at the base of the tibial spines. Tegmina yellowish brown, hind wings brownish grey (Fig. 7G, H ). Abdomen pale yellow, with black stripes along lateral margins of sterna and reaching the end of abdomen. Cerci pale yellow to yellowish brown (Fig. 7L ). Styli yellowish brown (Fig. 7N ).

Head. Vertex slightly exposed, interocellar distance wider than the distance between eyes, narrower than the distance between antennal sockets (Fig. 7F ). Pronotum subelliptical, broader than long, anterior and posterior margins nearly straight, and postero-lateral angle blunt and round; disc with symmetrical spots but without stripes (Fig. 7E ). Fifth maxillary palpus expanded, third and fourth maxillary palpi nearly equal in length, both longer than fifth maxillary palpus (Fig. 7J ). Tegmina and hind wings. Tegmina and hind wings fully developed, both extending beyond the end of abdomen (Fig. 7A, B ). Tegmina with M and CuA radial, M straight with seven complete branches. Hind wings with ScP and RA expanded at apex, M simple, without branches; CuA with four complete branches (Fig. 7G, H ). Legs. Anteroventral margin of front femur Type B2 (Fig. 7K ). Four proximal tarsomeres with pulvilli. The pretarsi with arolium, tarsal claws symmetrical and slightly specialized, with minute denticles on ventral margins.

Abdomen and genitalia. Eighth abdominal tergum specialized, with a sparse tuft of bristles in the middle (Fig. 7I ). Supra-anal plate symmetrical, the middle of anterior margin slightly concave, posterior margin arcuate produced with setae. Paraprocts simple, similar and flaky, obtuse at apex and each with a spiniform process at the base (Fig. 7L ). Subgenital plate nearly symmetrical, anterior margin distinctly concave in the middle, left and right margins both produced in the middle, posterior margin truncate. Styli similar, conical. Cerci long, with setae on the ventral surface (Fig. 7N ). Left phallomere large, irregular, bone-shaped, and with spines processes, apex curved upwards with rod-like structure (Fig. 7M ). Median phallomere slender rod-shaped, apex with sparse brush-like structure composed of spines of various sizes; accessory sclerite I arched; accessory sclerite II with a lamellar structure with small spines (Fig. 7N ). Hook phallomere on the right side, apex curved inwards with a short spine (Fig. 7O ).

Female. Similar to the male (Fig. 7C, D ).

Diagnosis.

This species is similar to M. bisignata Bey-Bienko, 1970 in general appearance, but can be differentiated from the latter by the following characters: 1) left phallomere with a short spiny process; the latter with a long spine process; 2) median phallomere apex with sparse brush-like structure composed of spines of varying sizes; while in the latter, median phallomere curved at apex, sheet-like, and with brush-shaped structure.

Etymology.

The species name parabisignata reflects its similarity to M. bisignata Bey-Bienko, 1970.

Distribution.

China (Hainan).
