Diagnosis Horn-cores with a strong anterior keel, without much tendency to a postero- lateral keel, with some rounding of the cross-section on either side of the anterior keel so that its shape, even near the base, is not neatly triangular, horn-cores inserted at a low inclination in side view, strongly divergent basally in anterodorsal view and curving strongly so that at the tips they are parallel or even slightly convergent. Slight backward curvature of the horn-cores is not confined to their basal sector. Sometimes with deep longitudinal grooves on posterior surfaces of horn-cores. Localized rugose areas on the front of the pedicels below and in line with the anterior Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original South African Museum.
