SMICRONYX OVIPENNIS GROUP 
Description: Rostra of both sexes moderately curved, stout; 
smoother and more shining in the female (fig. 27). Prothorax strongly 
rounded on the sides, strongly convex dorsally, narrowed and slightly 
constricted at the apex; disk deeply and closely punctured with sub- 
angular punctures (fig. 26). Elytra slightly inflated near the middle, 
humeri distinct, declivities indistinct (fig. 26). Median lobe of male 
genitalia rather elongate, the sides subparallel (figs. 85-87). 
Discussion: The species of this group are similar to the S. abnormis, 
S. griseus, and S. resplendens groups in respect to genitalia, but may 
be distinguished from those groups by the shape of the prothoraxes, 
which are quite convex in the S. ovipennis group, but not in the other 
three groups, and by the shape of the elytra, which are inflated only 
in the S. ovipennis group. 
Map 13 gives the distribution of this group.
