Male pygidium (tergite VIII) and part of propygidium (tergite VII) exposed; pygidium ca. 0.8 × as long as wide; in dorsal view, transverse, edge completely convex, forming a distinct rim around disc, apical edge straight, not arched, with an incurved tongue-like process (Figs 26, 33), being an abrupt internal projection of apical pygidium margin; in lateral view, pygidium disc weakly convex, coarsely punctured and sparsely pubescent with short hairs.</p><p>Legs. Femora incrassate, with 1 + 3–4 teeth (usually 3). Tibiae more or less straight, slightly longer than femora; pro- and mesotibia mucronate, metatibia unarmed in male, all tibiae unarmed in female.
