[ Abstract]
Characteristics
The members of the Cichlasomatini are characterised most obviously by the possession of relatively large scales, especially shown in the arrangement of the scales in front of the
dorsal fin where there are eight scales along midline rather than over 10 scales. Stiassny posited in 1991 that laying eggs in a tight circular clutch was a
synapomorphy of the cichlasomines.
