The genus Scaphioides Bryant contains species that resemble those of Stenoonops Simon but lack the sternal and palpal synapomorphies of that genus and have a longitudinal ridge on the male endites, a short, wide male embolus, and a more heavily sclerotized epigastric scutum in females. As delimited by those characters, the genus is circum-Caribbean in distribution and contains at least 19 species, including 11 described as new: S. campeche from the Yucatan peninsula of Mexico, S. irazu from Costa Rica, S. bimini and S. gertschi from the Bahama Islands, S. camaguey, S. granpiedra, S. siboney, S. cobre, and S. yateras from Cuba, S. miches from Hispaniola, and S. reductoides from the Virgin Islands. The male of S. halatus (Chickering) is described for the first time. A new genus, Hortoonops, is established for three similar Caribbean species that lack the synapomorphies of both Stenoonops and Scaphioides, but are united by peculiar excavations on the anterior metatarsi that represent an extraordinary convergence with the structures found in the African corinnid genus Hortipes Bosselaers and Ledoux. Stenoonops lucradus Chickering from the Virgin Islands and Stenoonops portoricensis Petrunkevitch from Puerto Rico are transferred to Hortoonops, and a new species, H. excavatus, is described from Hispaniola.
