Description. Adult. Coloration. Ochreous to brown; clavus dark brown, remigium lighter.
Structure. Body, in dorsal view, oblong-oval. Head with strongly curved fore margin; anterior rim indistinctly delimited from membrane; areolae, in longitudinal body axis, relatively long; eyes moderately recessive; hind margin of eye and postero-lateral margin of head forming an obtuse angle. Pronotum with distinct median longitudinal ridge, smooth posteriorly, at most finely punctate postero-laterally. Paranota relatively large, about as wide anteriorly as posteriorly, with widely curved margins; smooth postero-ventrally. Tegmen with vein M reduced basally, basal radial cell without additional veins in apical half of vein M+CuA. Male and female terminalia as in Figs. 27 View FIGURES 21 – 33 , 34, 41 View FIGURES 34 – 47 , 48, 55 View FIGURES 48 – 61 , 62, 63 View FIGURES 62 – 73 . Male anal tube narrowly oval, in dorsal view, widest in basal third, irregularly narrowing to apex, with slightly sinuous margins. Pygophore with comparatively long and narrow median posterior tooth; postero-lateral edges distinctly angular. Parameres short, rounded apically. Aedeagus, in anterior view, with broad, irregularly rounded head, narrowed subapically, and almost subquadrate antero-proximal lobes; posterior outline of neck, in profile, with distinct angle; spines on neck indistinct, a few at most. Female tergite 9 with ventral margin strongly indented in apical third. Ventral teeth of valvulae 1 moderately large.
