" Species of Gambusia such as G. affinis and G. geiseri, which have males with acute gonopodial tips have females whose genital opening terminates in a papilla. Species such as G. heterochir or G. regani have males with blunt gonopodia and with small gonopodial hooks and their females have a genital opening terminating in an enclosed sinus. Such similarities in structure between species currently recognized from different species groups probably indicates a functional adaptation for more efficient sperm transfer during conspecific matings "
