ABSTRACT
The 19 species of Deronectes which occur in the southwestem United States, Mexico, and Guatemala are treated in this study. Two new species, D. spectabilis and D. minax, are described and 2 more species are recognized, but not described because males are not known. D. nebulosus (Sharp) is a junior synonym of D. roffi (Clark) and what was thought to be D. roffi is renamed and redescribed as D. spectabilis. D. corvinus (Sharp) and D. opaculus (Sharp) are shown to be distinct, and so are D. coelamboides (Fall) and D. panaminti (Fall).
