Discussion. This endemic Hispaniolan species, described recently by Lingafelter and Woodley (2007), is known from only three specimens, all collected in June and July along the Cabo Rojo road in the extreme southwestern part of the Dominican Republic. No additional material has been collected since its description.

Derancistrus hovorei , with its vittate elytra, is morphologically similar only to D. elegans and S. vittata . It differs from the latter by its large, spine-like lateral processes on the pronotum and distinctly bilobed posterior margin of the prosternal process. In males, the pronotal margins of S. vittata are nearly parallel and slightly erose; in females, the pronotal margins are crenulate, with the posterolateral margin acutely produced but not as spine-like as in D. hovorei . The posterior margin of the prosternal process is evenly rounded in both sexes of S. vittata . Derancistrus hovorei differs from D. elegans by having obvious coarse punctation on the elytra (nearly impunctate in D. elegans , the tiny punctures not apparent without high magnification) and in having the median lateral spine of the pronotum shorter and less hooked than in D. elegans .
