摘　　要：How many species of life are there on Earth?This is a question that we want to know but cannot yet answer.Some scholars speculate that the number of species may reach 2.2 billion when considering cryptic diversity and that each morphology-based insect species may contain an average of 3.1 cryptic species.With nearly two million described species,such high estimates of cryptic diversity would suggest that cryptic species are widespread.The development of molecular species delimitation has led to the discovery of a large number of cryptic species,and cryptic biodiversity has gradually entered ourfield of vision and attracted more attention.This paper introduces the concept of cryptic species,how they evolve,and methods by which they may be discovered and confirmed,and provides theoretical and methodological guidance for the study of hidden species.A workflow of how to confirm cryptic species is provided.In addition,the importance and reliability of multi-evidence-based integrated taxonomy are reaffirmed as a way to better standardize decision-making processes.Special focus on cryptic diversity and increased funding for taxonomy is needed to ensure that cryptic species in hyperdiverse groups are discoverable and described.An increased focus on cryptic species in the future will naturally arise as more difficult groups are studied,and thereby,we mayfinally better understand the rules governing the evolution and maintenance of cryptic biodiversity.
