Structure: Female scale elongate and narrow, almost parallel-sided, with median elevated ridge, showing a distinct median ridge. Adult female body long, slender fusiform. Median pygidial lobes forming a definite notch in the apex of the pygidium, the mesal margin of the lobes being much longer than the lateral margin, the apices projecting little, the lobes narrow, divergent and with the mesal margin finely serrate. 2nd lobes large and prominent, the outer lobule somewhat smaller than the mesal lobule. 3rd lobes smaller than the 2nd, but of the same form (Rao, 1949). This species may be recognized among the species of the acuminata group by the antennal seta having a trace of fusion of 2 setae always visible; median pygidial lobes a little sunken basally into apex of pygidium, smaller than mesal lobule of second pygidial lobe, divergent, distinctly serrate on mesal margins; second and third pygidial lobe with lobules well developed, expanding apically.
