Identification
Mesaphorura are distinguished from other Tullbergiidae by features of the (springing organ) and chaetotaxy (bristle arrangement). The is characterized by the absence or strong reduction of , a trait shared with other Tullbergiidae but with specific configurations diagnostic at genus level. Detailed identification requires examination of antennal segments, claw structure, and abdominal patterns.

Habitat
Soil-dwelling; found in diverse substrates including desert soils, tropical forest litter, and Antarctic terrestrial . Records span from lowland tropical to high-altitude Andean and subantarctic environments.
Distribution
Documented from: African Indian Desert region, Amazon basin, Andean region, Antarctic and Subantarctic islands, and the Antillean region including southern Florida.
Ecological Role
Contributes to soil decomposition processes as part of the soil microarthropod . Their presence across extreme environments (Antarctica to tropical deserts) suggests functional importance in nutrient cycling under varied climatic conditions.
