Phylogeny and Classification

Tuxen (1964) recognized two suborders and three families within the class and order Protura, namely, the Eosentomoidea (family EOSENTOMIDAE) and Acerentomoidea (families ACERENTOMIDAE and PROTENTOMIDAE). However, following the description of Sinentomon erythranum by Yin (1965), which shows morphological features of all three families and may be the most primitive living proturan, some authors (e.g., Nosek, 1973) have placed this species in its own suborder Sinentomoidea (family SINENTOMIDAE). Though most workers consider the Eosentomidae and Sinentomidae as the most primitive proturans, their possession of a tracheal system and certain features of their sperm have led Yin (1984) to propose that they are more specialized than the Acerentomoidea.
