Shining disco: shedding light into the systematics of the family Discodorididae (Gastropoda: Nudibranchia)

The evolutionary relationships among genera within the nudibranch family Discodorididae remain poorly understood, with comprehensive molecular studies still largely absent. Discodoris, the most species-rich genus within this family, has historically represented a wastebasket taxon where species with...
