Exploring mitogenomic data to enhance the understanding of Seirinae (Collembola: Entomobryidae) evolution, distribution and taxonomy

Abstract

Abstract The subfamily Seirinae (Collembola: Entomobryidae) is among the most diverse suprageneric taxa of epedaphic springtails and is particularly abundant and species-rich in tropical and subtropical regions. Numerous studies have investigated its internal and external phylogenetic relationships, enhancing our understanding on Seirinae systematics. Recent taxonomic efforts have also advanced our knowledge on the subfamily morphology and diversity. In this study, we reevaluate the phylogeny of Seirinae using the mitogenomes of 26 samples from different continents, aiming to discuss recent findings regarding the group systematics, to identify cases of alien species introduced in China and Thailand, and propose new synonyms for Seira spp. Additionally, we describe a new species from Thailand and provide a redescription of Seira brasiliana (Arlé) based on the study of Brazilian and Chinese specimens. Through these efforts, we provide further ground for understanding the evolution, systematics, distribution and taxonomy of the group, contributing to future studies on Seirinae and Entomobryidae.
