Isotominae is a of springtails (Collembola) in the Isotomidae, characterized by elongate body forms. The group comprises approximately 15–16 and at least 100 described . Recent phylogenetic studies based on mitogenomes have challenged the monophyly of Isotominae, suggesting the subfamily may be with respect to other isotomid subfamilies. Members are distributed across diverse soil worldwide.
