Belongs within: Collembola.
The Tomoceridae are a group of elongate springtails in which the third abdominal segment is longer than the fourth (Womersley 1939). Tomocerinae have both an elongate mucro and the fourth antennal segment much shorter than the third, whereas Lepidophorellinae do not have both features together (Soto-Adames et al. 2008).
Characters (Womersley 1939): Postantennal organ absent. Abdominal segment 3 longer than 4, all tergites free. With or without scales, if present then these with longitudinal ribs. Ciliated sensory setae present on abdominal segments or not. Furca present and well developed.
