Thorax short and comparatively broad, the pro-meso- and meso-metanotal sutures very distinct and well-marked, the pro- notum, mesonotum and basal portion of the metanotum convex, the last obliquely truncate at apex, the truncate apical portion much longer than the basal portion; legs short, somewhat stout and densely pubescent.
