Pseudachorutes aphysus
Christiansen & Bellinger, 1980
Pseudachorutes aphysus is a of in the Neanuridae, described by Christiansen and Bellinger in 1980. It belongs to the order Poduromorpha, a group of primarily soil-dwelling Collembola. The species is known from the Pacific North American region. Like other members of the Pseudachorutes, it is likely adapted to moist soil . Available information on this species is limited due to its rarity in collections and the specialized nature of springtail .

Identification
Pseudachorutes aphysus can be distinguished from other Pseudachorutes by characteristics described in the original 1980 description by Christiansen and Bellinger. Members of the Pseudachorutes generally lack a (springing organ), or have it reduced, distinguishing them from many other . Identification to species level requires examination of chaetotaxy (bristle arrangement), body pigmentation patterns, and antennal structure under microscopy. The "aphysus" may refer to morphological features of the species, though this requires verification from the original description.
Distribution
Pacific North American region. Specific localities are not well documented in available sources.
Similar Taxa
- Other Pseudachorutes speciesCongeneric share the reduced or absent characteristic of the and require detailed morphological examination for differentiation.
- Other Neanuridae genera members share the poduromorph body plan and reduced jumping ability; separation requires analysis of structure, mouthparts, and body chaetotaxy.

Taxonomic Note
The Pseudachorutes is part of the Pseudachorutinae within Neanuridae. This group represents an early-diverging lineage within the , characterized by simplified mouthparts and reduced . The was described based on material from the Pacific Northwest of North America.
Data Limitations
Only 2 observations are recorded in iNaturalist, and the is rarely cited in ecological literature. This reflects both the cryptic nature of soil-dwelling springtails and the specialized taxonomic expertise required for identification.
