SMICRONYX WEEVILS—ANDERSON 319 
SMICRONYX RESPLENDENS GROUP 
Description: Body rather elongate and subcylindrical. Prothorax 
broadly rounded on sides, narrowed toward apex; disk evenly but not 
very closely covered with shallow rounded punctures. Elytra elon- 
gate, the sides subparallel for about three-fifths of their length, then 
eradually convergent to apex; bumeri distinct, declivities indistinct. 
Fourth tarsal joint rather elongate. Propygidium of male bearing 
a small projection above each of the spiracles and having a series of 
strong setae on the lobes of the posterior margin (fig. 38). Median 
lobe of male genitalia elongate, the sides subparallel (figs. 91, 92). 
Discussion: The two species in this group are unlike any other 
species in the subgenus Pseudosmicronyz in having the small projec- 
tions and heavy spines on the propygidia of the males, as described 
above. The male genitalia of this group resemble those of the S. 
abnormis, S. griseus, and S. ovipennis groups, but the general body 
shape of those groups is not elongate, as in the S. resplendens group. 
Thus, S. resplendens Dietz and S. pusio LeConte apparently form a 
small but very distinct group.
