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
); apical ventral margin of periandrium with a bifurcated process (
Fig. 9M
); endosoma lamellar, basal left side of dorsal margin with small teeth (
Fig. 9L
).
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
). 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
) 1.8× as long as wide; lateral carinae strongly elevated, median carina absent. Frons (
Fig. 9D
) 2.7× as long as wide. Pronotum (
Fig. 9A, C
) 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
) 2.3× as long as wide, with thirteen apical cells and six subapical cells; RP with 4 branches; MP with 5 branches: MP

. Metatibiotarsal formula 8/7-8, second segment of hind tarsus with one platella.
MALE GENITALIA. Pygofer (
Fig. 9F–G
) in ventral view symmetrical; in lateral view, lateral lobes arcuate and extended caudally. Medioventral process rounded in ventral view. Anal segment (
Fig. 9F, H
) 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
) 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
) 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.

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
).
