The neotropical genera of Naucoridae include Ambrysus and Procryphocricos, both in the subfamily Cryphocricinae. Ambrysus is a hyperdiverse genus that reaches its greatest richness in Mexico. In contrast, Procryphocricos is known by only three described species in northern South America. Described here are Ambrysus cayo n.sp. from Belize and Procryphocricos pilcopata n.sp. from Peru. Included are comparisons with congeners and information about habitats.
