Morphology and Anatomy:

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.
