Morphological and Cyto-Nuclear Conflicting Signals Across Non-Sister Lineages in Darkling Beetles (Tenebrionidae: Akis)

: Our results indicate that cyto-nuclear discordances between mitochondrial and nuclear markers, even across morphologically well-differentiated non-sister lineages, may be more frequent than previously assumed in darkling beetles, highlighting both their evolutionary relevance and the need for caution when relying solely on mitochondrial data for species identification.
