Abstract

A reassessment of the adult and larval morphology as well as comparison with published molecular information confirms the monophyly of the genus Calyptraeotheres Campos, 1990, and its relationship with Dissodactylus Smith, 1870, Clypeasterophilus Campos & Griffith, 1990 and Tumidotheres Campos, 1990. Calyptraeotheres pepeluisi new species, is described from Michoacán, Mexico on the basis of a female specimen. The new species is distinguished from the other nominal species of the genus by having a subarcuate carapace with longer setae on its front and anterolateral margin, the eyes are dorsally visible, and a third maxilliped with a 2-segmented palp and a conical propodus.
