PRONOTUM. 0.25 mm wide, 0.17 mm long ( Fig. 72B ). ELYTRA. 0.41 mm long, 0.35 mm wide, foveolae deeper than those on pronotum. MESOVENTRITE. Medial extension of collar broad; mid-keel with concave lateral margins, the anterior corners wider than the posterior corners which do not reach the mesocoxal anterior borders, shallowly raised before keel with ± six setae from concave foveolae; keel short, pointed, terminating close to rear margin of mesocoxae; lateral margins of mesoventrite without serrations ( Fig. 72C ).
