Centroleninae
# Centroleninae

Centroleninae is one of two subfamilies of the family Centrolenidae. It has nine genera distributed in Central America from Honduras south and east to northern and central South America. As of mid 2015, it contains 117 species.

## Taxonomy

Centroleninae are defined based on molecular and morphological characteristics, none of which are obvious to a naked eye. However, in several species a fighting behaviour that might be synapomorphy has been observed: males dangle by their feet and grapple venter-to-venter; amplexus-like or wrestling on leaves fighting of Hyalinobatrachinae is hypothesized to be primitive behaviour. Their sister taxon is ambiguous, it is either genus Ikakogi or subfamily Hyalinobatrachinae.
