Apicoscrobal hair short, stiff and stout; dorsolateral margin of occipital lobe posterior to this with about 10 stiffly projecting spatulate to remiform short hairs that gradually decrease in size posteriorly. Cephalic dorsum with standing hairs restricted to a stubbly transverse row along the occipital margin. Eye relatively large, maximum diameter in profile ca 0.12, with 7-8 ommatidia in the longest row; the maximum diameter of the eye is distinctly greater than the maximum width of the scape (ca 0.08).
