Molecular phylogenetic analyses support the monophyly of Hexapoda and suggest the paraphyly of Entognatha.

ABSTRACT:

Background

Molecular phylogenetic analyses have revealed that Hexapoda and Crustacea form a common clade (the Pancrustacea), which is now widely accepted among zoologists; however, the origin of Hexapoda remains unresolved. The main problems are the unclear relationships among the basal hexapod lineages, Protura (proturans), Collembola (springtails), Diplura (diplurans), and Ectognatha (bristletails, silverfishes, and all winged insects). Mitogenomic analyses have challenged hexapod monophyly and suggested the reciprocal paraphyly of Hexapoda and Crustacea, whereas studies based on nuclear molecular data support the monophyletic origin of hexapods. Additionally, there are significant discrepancies with respect to these issues between the results of morphological and molecular studi
