Coloration. Vertex, pronotum, mesonotum dirty yellowish brown ( Fig. 2 ). Frons, genae, clypeus yellowish brown to brown, except transverse stripe below level of lower margin of eyes and transverse stripe of apex of frons yellowish white ( Fig. 3 ). Eyes dirty yellowish brown. Antennae brown, except lateral margin of first segment, lateral margin and apex of second segment yellowish white. Thorax with sterna, including coxae of legs dark brown, except regions between median and hind legs yellowish white. Legs yellowish white to yellowish brown, with dark brown maculations ( Fig. 1 ). Forewing pale yellowish white, almost hyaline, basal part near costal margin with big infuscate markings, and apical part from transverse veins to apex with dark brown markings. Veins dark brown, with short white stripes at intervals, dark brown stripe along veins of apical region. Pterostigma blackish brown. Abdomeinal terga blackish brown, pleura and sterna blackish brown, except posterior margin of each segment reddish orange. Pygofer, anal segment blackish brown. Genital styles, aedeagus yellowish brown.

Head and Thorax. Head including eyes wider than pronotum (1.09:1). Vertex wider at base than long submedially about 2.5:1. Frons longer in middle line than wide at widest part about 1.7:1. Antennae with first segment shorter than second segment about 0.6:1, second segment long oval, somewhat compressed laterally, longer than wide about 3.0:1 ( Fig. 3 ). Pronotum slightly longer than vertex submedially (1.06:1). Mesonotum longer than pronotum and vertex combined about 2.40:1 ( Fig. 2 ). Basal segment of digitus longer than second and third together, about 1.6:1.

Male genitalia. Anal segment ring-like ( Figs 4–6 ). Pygofer in profile ( Fig. 5 ) much longer ventrally than dorsally, posterior margin somewhat sinuate, in posterior view ( Fig. 4 ) with opening longer than wide, ventral margin with 3 medioventral processes, median one short, broad, tapering, lateral ones very slender, long, sinuate. Phallus ( Fig. 7 ) long, with aedeagus and phallobase. Aedeagus tubular, arising from base of phallus, running dorsad, then curving ventrad, basal-ventral margin with short, small process. Subapical part of aedeagus turning left strongly, with node at apex, apex with 2 stout processes: left one directed laterodorsad, right one directed dorsad. In addition, 2 processes at subapical part of aedeagus: one slender, short, directed ventrad, another one stout, long, directed right-dorsad. Process of phallobase tubular, as thick as phallus, arising from base of phallobase, running dorsad, then curving caudad, after median part, turned left then ventrad, tapering apically. Genital styles slender, long, bent near middle, tapering apically ( Fig. 8 ).
