Delimiting species of Protaphorura (Collembola: Onychiuridae): integrative evidence based on morphology, DNA sequences and geography
Abstract Species delimitation remains a significant challenge when the diagnostic morphological characters are limited.Integrative taxonomy was applied to the genus Protaphorura (Collembola: Onychiuridae), which is one of most difficult soil animals to distinguish taxonomically.Three delimitation approaches (morphology, molecular markers and geogra
