Species and taxonomy

Before the genus Talamancaheros was recognized, these species had been placed in several other genera, including Cichlasoma, Heros, Theraps, Tomocichla and others, but they are not particularly closely related to any of these. The nearest relative of Talamancaheros is Isthmoheros tuyrensis.
There are currently two recognized species in this genus:Talamancaheros sieboldii Talamancaheros underwoodi
Until 2016, T. underwoodi was included as a population of T. sieboldii. T. sieboldii is now restricted to Panama, while T. underwoodi is restricted to Costa Rica.
