Parapharyngodon Chatterji, 1933

Bursey and Goldberg,(2005) consider that the genus Parapharyngodon differs from Thelandros because males of Thelandros have a genital cone, pendulant papillae that are outside the genital cone, an accessory piece is present in some species, and the tail is terminal and directed posteriorly; males of Parapharyngodon lack a genital cone, mammilliform papillae surround a more-or-less terminal anus, an accessory piece is absent, and the tail is subterminal and directed dorsally. Females of Thelandros have various caudal morphologies; eggs with a terminal operculum that have developed to juvenile stages when released; females of Parapharyngodon have a conical tail that tapers evenly from the anus or a rounded posterior end supporting a stout spike; eggs with a subterminal operculum that either uncleaved or in the early stages of cleavage when released.

Species of Parapharyngodon are distinguished by the pattern of caudal papillae, morphology of the anterior cloacal lip (outgrowths presence/absence), location of the ovary and geographical distribution (Bursey & GoldBerg, 2005). Species differentiation is also based on features like the form and length of lateral alae, length of spicule and form of distal tip, form of female tail, egg size.
