Second radial abscissa (3-SR) 1.9 times as long as first abscissa (r), 0.45 times as long as the almost straight third abscissa (SR1), about as long as second radiomedial vein (rm). Second radiomedial (submarginal) cell medium size, very weakly widened apically, its length 2.8 times maximum width, 1.15 times length of the narrow brachial (subdiscal) cell.

SCULPTURE AND PUBESCENCE. Vertex coarsely undulately transversally striate, with additional dense rugosity between striae; frons with coarse oblique and irregular striae. Face entirely rugose-striate; temple smooth in anterior half, partly subvertically striate with rugosity in posterior half, with coarse short rugae along occipital carina. Mesonotum entirely coarsely transverse-curvedly striate with dense rugulosity, partly with granulation between rugae. Scutellum entirely rugulose-granulate. Mesopleuron distinctly longitudinally striate in upper two-thirds, smooth posteriorly and below sternaulus. Metapleuron entirely coarsely rugose-reticulate.
