Abstract

Background: Symphyla is a group of widely distributed and common meso- to micro- soil arthropods. Some of them are important underground pests that cause damage to agricultural and forestry crops, having potential economic importance. However, compared to other small to medium-sized soil fauna, taxonomic studies on Symphyla remain fairly inadequate. To date, only about 250 species of Symphyla have been described globally, mainly from Europe, Americas and part of Africa, while only 19 species are known from China. 

Contents: This paper comprehensively summarizes the history of taxonomic studies and recent advances of Symphyla since their discovery in 1763, distills the main diagnostic characters and elaborates on their applicability and taxonomic value. Through a thorough assessment of the current status of symphylan species diversity worldwide and in China, we highlight existing problems in symphylan research and propose potential solutions. At present, the global species diversity of Symphyla is severely underestimated, indicating great potential for future discoveries of new species. 

Prospects: Facilitated by integrative taxonomy and diverse technical approaches, taxonomic research on Symphyla is expected to become more systematic, meticulous, and standardized. At the same time, research efforts in biogeography, ecology, biomimetics, and plant protection should be strengthened, so as to provide a scientific basis for biodiversity conservation, bioresource exploitation, and national food security in China.
