Figs 1–5 , 61 , 77 .

Diagnosis. Medium-sized species ( Fig. 1 ). Forewing 27 mm, hind wing 25 mm. Body dorsal coloration dark brown with pale markings, ventral coloration yellow. Mesonotum unspotted ( Fig. 2 ). Tarsomeres 3 and 4 black ( Fig. 5 ). Tibial spurs curved apically, longer than first tarsomere. Last segment of labial palp spindle-like ( Fig. 4 ).

Description (Based on 1 male). Head ( Fig. 3 ). Labrum, clypeus and frons yellow. Anterior tentorial pit small, narrow and shallow. Vertex raised, with dark marking above antennae and irregular brown markings on dorsal surface. Last labial palp segment oval-shaped with a small oval palpimacula ( Fig. 4 ).

Thorax ( Fig. 2 ). Notum dark and light brown. Mesonotum without well-defined dark spots.

Legs. Fore and middle legs with femora pale; tibia pale with light brown band proximally and medially, dark brown apically; tibial spurs extending beyond tarsomere 2. Hind legs more slender than fore and mid legs ( Fig. 5 ), pale with apices of femora black; tibial spurs as long as tarsomeres 1+2. In all legs tarsomeres 1, 2, 5 pale, 3, 4 dark and femora and tibiae with erect stout white setae.

Wings. Apices sub-acute. Forewing main longitudinal veins with alternating bands of white and very pale brown. Membrane hyaline with very pale suffused spots along CuA1. Pterostigma unconspicuous. Six presectoral crossveins. Hind wings veins pale. Membrane hyaline. Five presectoral crossveins.

Abdomen. Tergite 1 pale brown with erect thin white setae. Tergite 2 mainly dark brown with anterior margin bordered with light brown. Remainder of abdomen with alternating pale and dark brown bands; the anterior pale area with dark markings and two X-shaped thin lines. All sternites yellow.

Male genitalia ( Fig. 61 ). Gonarcus narrow, approximately triangular, with posterior edge raised. Parameres almost flat without projection, only upper part of inner edge slightly raised forward. Hypandrium internum with a stout short process ( Fig.77 ).

Female and larva unknown.
