Remarks.

This species does not exhibit sexual dimorphism. The available information is restricted to the original description and its inclusion in faunal survey lists. This species is documented within the Amazon biome. Eucyane dejanira was previously allocated in the genus Hypocrita and subsequently moved to Eucyane by Laguerre (2017) based on a maximum likelihood analysis using CO 1 gene. However, this taxonomic decision shall be taken with caution because (i) while CO 1 is effective and species-level identification, the high mutation rate can make it challenging to compare sequences across very diverse taxa because when comparing distant lineages, similar nucleotide changes may occur independently in different lineages, leading to misleading phylogenetic relationships (ii) the taxonomic coverage used by Laguerre (2017) is narrow and should include more Pericopina genera.

For instance, Moraes et al. (2021) showed a phylogentic hypotesys where the genus Hypocrita is polyphyletic consisting of two unrelated groups (i) Hypocrita “ sensu strictu ” phylogenetically close to Netoche (ii) the other clade represented by E. temperata is phylogenetically close to the genera Ephestris and Thirgis. A wider taxonomic samplig and the use of nuclear genes are needed to clarify the phylogenetic relationship and the taxonomic valitidy of the genera Eucyane , Hypocrita , Chetone and Netoche , mainly because the evolution of the colour pattern within these genera was driven by mimicry relationships.
