Coloration. General color dark yellowish brown. Vertex dark yellowish brown, with lateral and median carinae yellowish white, bordered with dark brown, submedian carinae dark brown. Frons, clypeus and genae dark brown, carinae yellowish white. Rostrum dark brown, with apex yellowish brown. Eyes dark brown to blackish brown, ocelli reddish brown. Antennae with first segment blackish brown, except lateral margin and medial carina yellowish white, second segment yellowish brown to dark brown. Pronotum dark yellowish brown, except lateral margin yellowish white, carinae yellowish white, bordered with dark brown. Mesonotum dark yellowish brown, median carina yellowish white, bordered with dark brown. Thorax with lateral areas dark brown. Legs brown to dark brown, except fore tibiae reddish orange. Forewing ( Fig. 11 ) with a triangular brown marking at basal area of costal margin, apical portion hyaline, speckled with brown to dark brown markings, in dark portion veins bear yellowish white spots. Hindwing hyaline, with veins dark brown. Abdomen with dorsal areas blackish brown, ventral areas dark brown, except posterior half of each segment pale yellowish brown, which bear several brown spots laterally. Pygofer with ventral and lateral areas dark brown, the rest of it and anal segment brown.

Head and Thorax. Head including eyes wider than pronotum (1.14:1). Vertex ( Fig. 2 ) wider at base than long submedially about 1.92:1. Frons longer in middle line than wide at widest part about 1.74:1. Antennae with first segment shorter than second segment about 0.48:1, second segment cylindrical, longer than wide about 3.5:1 ( Fig. 10 ). Pronotum slightly shorter than vertex submedially (0.94:1). Mesonotum longer than pronotum and vertex combined about 1.90:1 ( Fig. 9 ). Forewing longer in middle line than wide at widest part about 2.64:1 ( Fig. 11 ). Basal segment of digitus longer than second and third together, about 1.6:1.

Male genitalia. Anal segment ( Figs 12, 13 ) ring-like, without ventral process. Pygofer in caudal view ( Fig. 12 ) with opening larger in length than width, ventral margin concave medially, a slender, median portion expanded process arising from lateral margin, pygofer in profile ( Fig. 13 ) with ventral margin longer than dorsal margin, posterior margin slightly sinuate. Genital style ( Figs 15, 16 ) slender, long, widen apically, with a small, rounded process at base, a spine-like process arising subapically from outer margin of apex. Aedeagus ( Fig. 14 ) tubular, narrowing apically, abruptly curved at basal 2/5, two strong processes arising from apex, the longer one directed dorsolaterally, then curved dorsally, the shorter one directed lateroventrally, then curved anteriorly with apical part directed laterally.
