The study of new material and the use of additional characters, including the sensory pores, of Stathmonotus corroborates the taxonomic assignment of Springer (1955). The osteology of S. (Parastathmonotus) sinuscalifornici is described, illustrated, and compared to that of the other five species of Stathmonotus. A key, distribution maps, color descriptions, and illustrations for all species are given.The Chaenopsidae of Stephens (1963) is expanded, based primarily on osteological characters, to include Neoclinus, Mccoskerichthys, and Stathmonotus. The expanded family is characterized by at least eight apomorphies, but its outgroup relationships are uncertain. Character evidence supporting the monophyly of the included taxa (Neoclinus, Mccoskerichthys, Stathmonotus, and the Chaenopsinae) is presented. Parsimony analysis of 61 morphological characters resulted in two most-parasimonious trees of relationships within the Chaenopsidae (differing only in the relationships of S. sinuscalifornici). Neoclinus is hypothesized to be the sister group of the remainder of the Chaenopsidae. Mccoskerichthys is hypothesized to be the sister group of a clade comprising Stathmonotus and the Chaenopsinae (= Chaenopsidae of Stephens, 1963). Within Stathmonotus, S. stahli and S. gymnodermis are hypothesized to form a monophyletic group (subgenus Auchenistius) that is the sister group of the remaining four species. Stathmonotus hemphilli is hypothesized to be the sister group of the remaining three species (subgenus Parastathmonotus). Within Parastathmonotus, S. lugubris and S. culebrai are hypothesized to be sister species. An equally parsimonious topology places S. sinuscalifornici as the sister species of S. hemphilli. Character support for these relationships is discussed, a classification of the Chaenopsidae is presented, and the biogeography of Stathmonotus is discussed.
