The genus Pseudosinella Schaeffer, 1897, with a cosmopolitan distribution, includes over 250 species; several occuring only in caves. It is separated from its sister genus Lepidocyrtus by the number of eyes (8+8 in Lepidocyrtus and fewer than 8 in Pseudosinella), although several authors have suggested the genus Pseudosinella is paraphyletic within Lepidocyrtus. Here we present a phylogenetic analysis of North American Pseudosinella and Lepidocyrtus based on morphological and molecular characters to resolve whether these two genera are monophyletic or if Pseudoseinlla is paraphyletic and the loss of eyes being a convergent character due to the invasion of caves.
