Principal characteristics. Head pale with dark brown spots ( Fig. 39 A); vertex pale amber; light brown antennae; scape almost as long as wide; covered by pale amber setae. Pro-, meso- and metanotum laterally dark brown, medially with yellowish band, entire surface densely covered by yellow setae. Legs pale amber with some dark brown spots; all segments covered by light brown setae. Wings posterodistally falcate and with acute apices, membrane hyaline dotted with numerous amber infuscations, veins light brown with many brown spots, both wings with an amber macula in the radial sector below of pterostigma; forewing densely dotted by dark brown spots mainly along wing margin, radial and cubital trace, pterostigma weakly marked; hindwing with membrane hyaline slightly dotted with light amber spots, mainly at the apex of the radial sector and wing margin, pterostigma barely perceptible. Abdominal tergites dark brown and covered by short pale amber setae.

Male ( Fig. 40 ). Ninth gonocoxites elongated, crescent-shaped in lateral view, medial lobe with some setae at apex; ninth gonapophysis elongate tapering towards the apex; complex of tenth gonocoxites C-shaped in lateral view with two finger-like processes located in dorsal and ventral regions; hypandrium internum elongated with the winglike lobes fused on the midline.

Female ( Fig. 41 ). Fused eighth gonocoxites + gonapophyses short, broad, with posterior margin possessing two deep rounded concavities separated by an elevated promontory; ninth tergite narrow, apices bluntly rounded; ectoproct short and nearly quadrate; fused ninth gonapophyses bifurcated; spermathecae reniform.
