Figs 13–16, 17–24

Diagnosis.

The new species can be distinguished from other species by the aedeagal shaft bifurcated at apex, crab claw-like, with one pair ½ length of aedeagal shaft basal processes; pygofer dorsal appendage expanded at base and tapering towards apex; subgenital plate with row of four macrosetae medially on outer surface; connective with central lobe broad and stem well developed.

Description.

Body brown (Figs 13, 16). Head slightly narrower than pronotum (Fig. 15). Crown fore margin strongly produced, with two irregular, medial, amber-colored patches (Figs 13, 15). Anterior part of pronotum light brown; posterior margin slightly darkened, with one nearly V-shaped, milky-white stripe. Coronal suture well developed. Eyes black (Figs 13, 14). Mesonotum brown. Forewing grayish brown (Fig. 14).

Male abdominal apodemes broad, extending to anterior margin of 4 th sternite (Fig. 24).

Male genitalia. Pygofer lobe broad, with numerous microtrichia scattered along caudal edge and dorsal margin (Fig. 21). Dorsal pygofer appendage with wide base and sharp apex (Fig. 22). Subgenital plate with a row of four macrosetae in middle and with marginal peg-like setae from subbase to apex forming continuous row (Fig. 20). Style long and slender (Fig. 17). Connective with lateral arms strong, central lobe broad and stem well developed (Fig. 23). Aedeagal shaft long, straight in ventral view, curved dorsad in lateral view, bifurcated at apex; crab claw-like and with pair of basal long processes; gonopore located at 1 / 2 height of aedeagal shaft, ventrad (Figs 18, 19).

Specimens examined.

Holotype: ♂; China, Yunnan Prov., Jinghong City, Mnegyang Town; 2 August 2021; Tianyi Pu leg.; GZNU -2021-YN-JH-6-001 . Paratypes: 41 ♂♂, 58 ♀♀, same data as holotype; GZNU -2021-YN-JH-6-002 to 100 .

Measurements.

Male length 2.3–2.4 mm, female length 2.4–2.5 mm (including wings).

Remarks.

This species is very similar to Motaga fara Dworakowska, 1980, but it differs from M. fara in having the dorsal pygofer process with a stouter base, the length of the aedeagal shaft proportionally longer compared to the basal processes, and the gonopore located at about halfway along the length of the aedeagal shaft.

Etymology.

The new species is named after its type locality, Mengyang Town.
