Species Guides
6Pseudosinella is a of slender-bodied springtails in the Entomobryidae, established by Schäffer in 1897. The genus contains more than 20 described distributed across diverse including tropical rainforests, temperate woodlands, and even Antarctic and subantarctic regions. Members of this genus are characterized by their elongated, cylindrical body form and reduced or absent pigmentation. They are part of the diverse soil and leaf litter fauna, contributing to decomposition processes.

Pseudosinella are distinguished from other entomobryid springtails by their slender, elongate body shape and generally pale or unpigmented coloration. They possess the -typical long and well-developed (springing organ) characteristic of Entomobryomorpha. Differentiation from the closely related Sinella requires examination of chaetotaxy (bristle arrangement) and dental structure of the , features not reliably visible without microscopic examination.
