Abstract The generic differences and similarities between Leptostylus LeConte and Leptostylopsis Dillon (Coleoptera: Cerambycidae: Acanthocinini) are discussed. Leptostylopsis is redescribed and the following species are transferred from Leptostylus to Leptostylopsis: Leptostylopsis annulipes (Fisher 1942), comb. n.; Leptostylopsis poeyi (Fisher 1925), comb. n.; and Leptostylopsis viridicomus (Fisher 1942), comb. n. Leptostylopsis hispaniolae (Fisher 1942) is a syn. n. of Leptostylopsis annulipes (Fisher 1942). Seven new species of Leptostylopsis from Hispaniola are diagnosed, described, and illustrated: L. basifulvus Lingafelter and Micheli, sp. n.; L. caliginosus Lingafelter and Micheli, sp. n.; L. chlorescens Lingafelter and Micheli, sp. n.; L. humerofulvus Lingafelter and Micheli, sp. n.; L. perfasciatus Lingafelter and Micheli, sp. n.; L. puntacanaensis Lingafelter and Micheli, sp. n.; and L. thomasi Lingafelter and Micheli, sp. n. Redescriptions and distributional data are provided for the six previously described species known from Hispaniola, and a dichotomous key to all thirteen species of Leptostylopsis from Hispaniola is provided.
