The Rivulidae ( Latin : "rivus" = river) are a family of South American toothpies (Cyprinodontiformes). They used to be counted among the Cyprinodontidae and are therefore called toothcarps like these egg-laying species . Sometimes they are associated with their Old World relatives in the Aplocheilidae family . They then form the subfamily Rivulinae. They live in fresh water , more rarely in brackish water . The Rivulidae are the fourth most species-rich fish family of the Neotropics .

features

They are small fish from 2.2 to 22 centimeters in length. Most of the over 400 species remain under 10 centimeters. The males are usually larger and much more colorful. Their unpaired fins are also larger. Many rivulids are seasonal fish . The diagnostic features of the Rivulidae include the continuous Branchiostegal and gill membranes, the sensory system reduced to the preoperculum and various features of the skull and fin morphology. As with the Nothobranchiidae , their relatives from the Old World , there are numerous seasonal fish among the Rivulidae that inhabit small bodies of water that regularly dry out.

Systematics

The group was scientifically introduced in 1925 by the American ichthyologist George Sprague Myers as the Tribus Rivulini (family Cyprinodontidae ) and only later became an independent family.

Many scientists are of the opinion that the name Rivulidae was preoccupied by Rivulini Grote , 1895, a moth tribus and instead of the name Rivulidae use the name Cynolebiidae , derived from Cynolebiatidi Hoedeman , 1961.
