Handschin, 1942 is a pantropical genus of Pseudachorutinae with 18 species, 16 of which are from the Neotropical Region and 13 from Brazil. The genus has several species with unclear descriptions. Herein, we describe a new species of , survey the genus based on published papers and discuss its morphology, providing an updated genus diagnosis plus a detailed comparison table and a key to all known species. sp. nov. is unique in the combination of a postantennal organ with 14-20 vesicles, its mandible with five teeth, its maxilla apically pointed and its unguis with a pair of reduced teeth. Widely distributed taxa may be species complexes, especially due to their unclear descriptions.

Background: is a genus of springtails which can be of medium size (2 mm) or relatively long (5 mm). These springtails live in leaf litter, under the bark of dead trees or in decomposing wood, mainly in the Neotropical Region and are often collected by litter samples on Berlese funnels or by pitfall traps. Most species have been described, based on relatively few specimens and chaetotaxy of several species is incomplete.

Aethiopella Handschin, 1942 as other Pseudachorutinae (Neanuridae) presents a diagnosis with overlapping characters when compared to other similar genera, especially Halachorutes Arlé, 1966, Ceratrimeria Börner, 1906 and Pseudachorutes Tullberg, 1871. This condition, combined to several gaps on the knowledge of described species and a wide range of morphological differences within the genus, reinforces the need of its revision, since it can be an artificial group. In spite of that, a new species, Aethiopella ricardoi sp.
