The genus Entomobrya are arboreal species with four antennal segments and elongated abd4. Entomobrya species are identified from dorsal pigmentation patterns. Unlike other groups, e.g. Tomoceridae, Entomobrya species are unscaled, so pigmentation patterns are more reliable.
Entomobrya albocincta has a broad pale band on the thorax:
Entomobrya intermedia has a characteristic broken “U” (the corners are missing) on abd.5/6 and a “W” across the top of abd.4.
Entomobrya nicoleti has only two dark spots on the sides of abd4:
Entomobrya nivalis has no inverted V shape (the central part of the W pattern in E. intermedia) at the top of abd4:
