Diagnosis
The salient features of the new species include: apical right side of the ventral margin of periandrium with a long spinose process, bending upwards, directed cephalad, parallel to periandrium ( Fig. 9J View Fig ); apical ventral margin of periandrium with a bifurcated process ( Fig. 9M View Fig ); endosoma lamellar, basal left side of dorsal margin with small teeth ( Fig. 9L View Fig ).
Etymology
The specific name is derived from the Latin adjective ‘ pallidus ’, referring to the forewings which are largely pale, white.

Description
MEASUREMENTS. Body length: male 7.0– 7.5 mm (N = 2).
COLORATION. General color yellowish white ( Fig. 9A–B View Fig ). Eyes brown, ocelli light red, semi-translucent. Antenna, vertex and face yellowish white. Rostrum yellowish brown. Anterior parts of pronotum white, posterior parts yellowish brown. Mesonotum yellowish brown. Forewing semi-translucent, whitish, costal vein with 3 small, spaced dark brown spots, from centre of ScP+ RA to near claval fork with a fawn-coloured stripe; middle part of clavus and behind clavus with an irregular puce spot, respectively; apical half of wing with yellowish brown patches.
HEAD AND THORAX. Vertex ( Fig. 9A, C View Fig ) 1.8× as long as wide; lateral carinae strongly elevated, median carina absent. Frons ( Fig. 9D View Fig ) 2.7× as long as wide. Pronotum ( Fig. 9A, C View Fig ) 1.1× as long as vertex; posterior margin forming a right angle. Mesonotum 1.1× as long as pronotum and vertex combined. Forewing ( Fig. 9B, E View Fig ) 2.3× as long as wide, with thirteen apical cells and six subapical cells; RP with 4 branches; MP with 5 branches: MP 11, MP 12, MP 2, MP 3 and MP 4; fork MP 1 +MP 2 basad of fork MP 3 +MP 4. Metatibiotarsal formula 8/7-8, second segment of hind tarsus with one platella.
MALE GENITALIA. Pygofer ( Fig. 9F–G View Fig ) in ventral view symmetrical; in lateral view, lateral lobes arcuate and extended caudally. Medioventral process rounded in ventral view. Anal segment ( Fig. 9F, H View Fig ) flat tubular, dorsal margin almost straight, ventral margin curved in lateral view; apical margin truncate, 2.2× as wide as long in dorsal view; anal style strap-shaped, not extending beyond anal segment. Gonostyli ( Fig. 9G, I View Fig ) symmetrical ventrally; in inner lateral view, dorsal margin concave, middle part of ventral margin convex, middle part expanded, then apical part gradually narrowed. Aedeagus ( Fig. 9J–M View Fig ) with seven processes. Apical ventral margin of periandrium with a long spinose process, bending upwards, directed cephalad, parallel to periandrium, directed right-dorsocephalad; apical dorsal margin of periandrium with a long spinose process, slightly curved, directed cephalad; below midlength of ventral margin of periandrium with a longish spinose process, directed dorsad; middle part with a short spinose process, directed cephalad, apex bifurcated, forming two spinose processes: dorsal one long, directed left-dorsocephalad, another short one directed ventrad. Endosoma lamellar, left side of base rolling upwards, right side of apex rolling inwards, nearly apical margin with a spinose process, directed dorsocephalad, basal left side of dorsal margin with small teeth.
Distribution
China (Guizhou).
Remarks
This species is similar to Andes lachesis Fennah, 1956 in appearance, but differs in: (1) apical ventral margin of periandrium with a long spinose process, bending upwards, directed cephalad, parallel to periandrium (apical dorsal margin of periandrium with a spinose process in A. lachesis ); (2) basal ventral margin of periandrium with a bifurcated process ( A. lachesis without process in the same position); (3) endosoma lamellar, basal left side of dorsal margin with small teeth (endosoma coarsely shagreen or sub-fimbriate in A. lachesis ).
