Length 16 mm. External characters as in generic description. 

 Pygofer with dorsal margin distincdy concave anteapically, elevated 

 and rounded apically in lateral aspect, microsetae numerous, ex- 

 tending in broad band along posteroventral margin to apex, with a 

 number of interspersed macrosetae, with very small submarginal 

 microsetae located dorsoapically; styles broadly truncate apically; 

 aedeagus in lateral aspect not as strongly arched as in S. sulcicollis 

 (Germar), in ventral aspect with shaft much broader than in S. 

 sulcicollis. Color sordid brown.

 lopola/n. sp." (RMS).
