Acaeroplastes

Distinguished from other Porcellionidae genera by characteristics of the male genital apparatus (pleopod 2 endopod structure) and details of uropod morphology. Differs from Armadillidium (Armadillidiidae) by incomplete conglobation and lateral uropod placement. Separation from Porcellio requires examination of pleopodal characters and antennal flagellum proportions. Identification to species level requires microscopic examination of reproductive structures.

Dorsoventrally flattened body typical of Porcellionidae. Body capable of loose conglobation (incomplete rolling into a ball). Exoskeleton with characteristic segmentation: head, pereon (seven thoracic segments with walking legs), and pleon (six abdominal segments). Antennae with two flagella. Uropods positioned laterally on the pleotelson, not forming a complete tail fan. Coloration variable among species, generally in earth tones.

Terrestrial environments; specific microhabitat preferences vary by species. Generally found in moist, sheltered locations under stones, logs, leaf litter, and in soil crevices. Requires humid conditions to prevent desiccation due to lack of a fully sealed exoskeleton.

Distribution varies by species; the genus has been recorded across parts of Europe and adjacent regions. Specific range boundaries for the genus as a whole are incompletely documented.

Functions as a detritivore in soil and leaf litter ecosystems, contributing to decomposition and nutrient cycling. Serves as prey for various small vertebrates and invertebrates.

Occasionally encountered in gardens and greenhouses. No significant economic impact documented; not considered a pest genus. Of minor interest to terrestrial isopod enthusiasts and researchers studying soil fauna.

• PorcellioAlso in Porcellionidae; differs in pleopod structure and antennal proportions
• ArmadillidiumDifferent family (Armadillidiidae); capable of complete conglobation with uropods enclosed, unlike Acaeroplastes
• OniscusDifferent family (Oniscidae); body shape more oval, uropods form distinct tail fan
