Consequently, additional dimorphic features associated to head size in males of Cathoropscould represent an adaptation to compensate for the smaller body lengths, allowing a relative increase of the branchial chamber. Whenever possible, variables in which differences were found between males and females are discussed under the sexual dimorphism section of each species. A New Freshwater Ariid Otophysi: Lateral and mesial surfaces of cathoropss and second gill arches without fleshy papillae intercalated with gill rakers.

Dorsomedian groove of neurocranium formed by frontals and supraoccipital, relatively deep and long, its margins well marked and progressively narrower posteriorly.

The species belonging to Cathorops have been traditionally distinguished by the absence of vomerine tooth plates and presence of one pair of small oval accessory tooth plates bearing molariform teeth.

Accessory tooth plates with small and not numerous molariform teeth.

Individual comparative diagnoses separating each species from other species from Mesoamerica and the Caribbean, including Cathorops mapale species group cathoropz Colombia and Venezuela, are also presented.
The ariid genus Cathorops includes species that occur mainly in estuarine and freshwater habitats of the eastern and western coasts of southern Mexico, Central and South America. Upper and lower lobes of caudal-fin quite short, upper lobe longer than lower lobe. Lips thick, lower lip thicker than upper lip.
