Etymology: Gambusia: Gambusia: From the Cuban term, Gambusino, which means "nothing", usually in the context of a joke or a farce. Fishing for gambusinos = when one catches nothing (Ref. 45335); quadruncus: Derived from the Latin quad (four) and uncus (hook) , in reference to the four hooked elements at the distal tip of the gonopodium.

Breve descrizione
Chiavi di identificazione | Morfologia | Morfometria
Raggi dorsali molli (totale) : 7 - 9; Raggi anali molli: 9 - 11; Vertebre: 30 - 33. Belongs to the affinis species group and differs from all other members of this group by the following combination of characters: terminal hook at the distal tip of the gonopodium formed by rays 4a, 4p or both; elbow on gonopodial ray 4a positioned more distal relative to serrae (typically positioned one segment or more distal to serrae) and anal spots in females that are permanent, more prominent and positioned more posteriorly than other members (typically spanning the second to fifth or sixth rays) (Ref. 91760).
Body shape (shape guide): fusiform / normal.
Occurs in a wide range of habitats such as ponds, drainage ditches, lakes, wetlands, brackish lagoons, large rivers and swiftly flowing spring-fed streams (Ref. 91760).
