Ercheiini
Ercheiini is a taxonomic tribe within the subfamily Larentiinae, belonging to the moth family Geometridae (geometer moths). These moths are generally found in Eurasia. The characteristics that define Ercheiini as a distinct tribe are based on a combination of morphological features of the adult moths, including wing patterns, and features of their reproductive organs. Their specific taxonomic relationships within Larentiinae, and indeed the precise definition of the tribe, can be subject to revision as new data from morphological and molecular studies become available. Genera that are frequently included in the Ercheiini tribe are Ercheia and related genera, though the exact list of genera included can vary depending on the source. Further research is ongoing to better understand the evolutionary relationships within this group.
