Diagnosis

The salient features of the new species include the following: apex of forewing dark brown across its entire width apart from a few pale spots ( Fig. 3A, C ); ventral margin of periandrium with a laminal process near base, bending up to the left ( Fig. 3M ); basal ⅓ of periandrium with an expanded semi-enclosed structure around the left and right side and ventral margin of periandrium ( Fig. 3J–K, M ); apex of periandrium with a long spinose process, curved dorsally to the base, then strong bending ( Fig. 3J‒M ).

Etymology

The specific name is derived from the Latin adjective ‛ fuscus ’, referring to an arcuate dark brown stripe from the apical margin of forewing.

Description

MEASUREMENTS. Body length: male 6.38‒6.82 mm (N = 6), female 6.80‒7.15 mm (N = 4).

COLORATION. General color yellowish brown ( Fig. 3A–B ). Eyes black brown, margin yellowish brown; ocelli faint red, semi-translucent. Lateral carinae of frons yellowish white; lateral side of head with a long brown spot anterior to the eyes. Antenna yellowish brown. Vertex dark brown. Face and rostrum generally dark brown. Pronotum yellowish brown. Mesonotum with area between lateral carinae darker brown, lateral areas yellowish brown. Forewing semi-translucent, slightly anterior and posterior to fork CuA with a narrow and small irregular puce stripe respectively, posterior to clavus with an elliptical black brown spot, apex of forewing dark brown across its entire width apart from a few pale spots. Stigma black brown. Veins and tubercles concolorous with wing. Hind tibiae yellowish brown. Abdomen yellowish brown ventrally.

HEAD AND THORAX. Vertex ( Fig. 3A, C ) 2.1 times as long as wide; anterior margin nearly straightly, posterior margin U-shaped recessed, lateral carina developed, median carina absent. Frons ( Fig. 3D ) 4.7 times as long as wide, lateral carina developed, base of median carina raised, median carina of postclypeus transparent. Pronotum ( Fig. 3A, C ) slightly shorter than vertex; posterior margin recessed. Mesonotum 1.1 times as long as pronotum and vertex combined. Forewing ( Fig. 3B, E ) 2.12 times as long as wide, with twelve apical cells and seven subapical cells; RP 3 branches, MP with 5 terminals: MP 11, MP 12, MP 2, MP 3, and MP 4, fork MP 1 +MP 2 basad of fork MP 3 +MP 4. Hind tibia ( Fig. 6B ) with five lateral spines; chaetotaxy of hind tarsi: 7/7–8, 2 nd hind tarsus with 2–3 platellae.

MALE GENITALIA. Pygofer ( Fig. 3F–G ) in ventral view symmetrical; in lateral view, lateral lobes arcuate and extended caudally. Medioventral process linguiform in ventral view, apex pointed. Anal segment ( Fig. 3F, H ) flat tubular, dorsal margin almost straight, ventral margin curved slightly in lateral view; 2.8 times as long as wide in dorsal view; anal style strap-shaped, not extending beyond anal segment. Gonostyli ( Fig. 3G, I ) symmetrical ventrally, middle part of inner margin with emarginations; gonostyli in inner lateral view L-shaped. Aedeagus ( Fig. 3J–M ) with a spinose process. Ventral margin of periandrium with a laminal process near base, bending up to the left; basal ⅓ of periandrium with an expanded semi-enclosed structure around the left and right side and ventral margin of periandrium; apex of periandrium with a long spinose process, curved dorsally to the base, then strong bending, directed dorsocaudad. Endosoma slightly sclerotized, without process.

FEMALE GENITALIA. Tergite IX ( Fig. 4A–B, D ) moderately sclerotized, without wax plate. Anal segment ( Fig. 4C ) rectangular, 2.2 times as long as wide in dorsal view, anal style linguiform. Gonapophysis VIII ( Fig. 4E ) elongate, and slightly curved upwards. Gonapophysis IX ( Fig. 4F ) with two middle teeth, denticulation unsharp. Gonoplac ( Fig. 4G ) rod-like, 4.4 times as long as wide in lateral view. Posterior vagina pattern as shown in Figure 4H–I .

Distribution

China (Yunnan).

Remarks

This species can be distinguished from the other species of the genus by the body color, forewing markings and male genitalia.
