Taxonomic History
The was established by Stephan von Breuning in 1940, with numerous described by Breuning himself in subsequent decades. Recent revisions by Santos-Silva, Wappes, and Galileo (2018) significantly expanded the genus with multiple new species from Mexico and Central America, indicating ongoing taxonomic work and likely remaining undescribed diversity.
Nomenclatural Note
epithets in this show complex patterns of authorship, with many originally described in other genera (particularly Estola) and subsequently transferred to Estoloides. The specific epithet 'esthlogenoides' references similarity to the genus Esthlogena.
