Tahuantinsuyoa is a genus of South American cichlids . The distribution area of ​​the genus includes the Río Aguaytía and the Río Pachitea , two tributaries of the Río Ucayali , which in turn is one of the two headwaters of the Amazon in Peru. The generic name comes from Quechua and was the name of the Inca for their empire ( Tawantinsuyu "empire of the four cardinal points").

features

Tahuantinsuyoa species are rather small cichlids and reach lengths of 8 to 12 cm. Females stay a little smaller. Characteristic features of the genus are four pores of the sensory system on each half of the lower jaw and a disordered (not arranged in rows) scaling in front of the dorsal fin. The body is elongated oval and laterally flattened, the color is light gray with a dark spot on the sides of the body, a dark line below the eyes and another in the neck. The sides of the head and body are covered with golden or bluish shiny dots that are arranged in irregular longitudinal rows.

Systematics

The genus is closely related to Bujurquina and forms with this genus and Andinoacara the sub- tribus Andinoacarina within the tribe Cichlasomatini. Tahuantinsuyoa differs from Bujurquina in that there is only one (front) joint between the palatal bone and ethmoid (two in Bujurquina ).

species

So far, two very similar species have been described, which can only be distinguished from the outside by the head markings:

Reproduction

Similar to Bujurquina , the Tahuantinsuyoa species are larvophilic mouthbrooders . As with substrate spawners, the eggs are first deposited on a transportable substrate such as leaves or pieces of wood, the larvae that hatch after about three days are then taken into the mouth by the parents, initially only by the female, later also by the male.
