Genus Guides
1Paleonurini is a tribe of springtails (Collembola) within the Neanuridae, Neanuridae, established by Cassagnau in 1989. Members of this tribe belong to the order Poduromorpha, one of the three major lineages of Collembola. The tribe contains multiple of soil-dwelling springtails found across various regions. As hexapods, they possess internal mouthparts and share characteristics typical of the Neanuridae family, including reduced or absent (springing organ) in many .

Identification
Identification to tribe level requires examination of chaetotaxy (bristle arrangement), body shape, and mouthpart structure under magnification. Paleonurini generally show the neanurid body plan: often cylindrical or slightly flattened bodies with well-developed . Distinguishing Paleonurini from other neanurine tribes (such as Neanurini or Sensillanurini) relies on specific arrangements of and setae on the body segments, particularly on the and .
