Alloniscus mirabilis
Wonderful Wracklouse
Alloniscus mirabilis is a terrestrial isopod (woodlouse) in the family Alloniscidae. The species epithet "mirabilis" (Latin for "wonderful" or "extraordinary") reflects its distinctive characteristics. As a member of the suborder Oniscidea, it is a fully terrestrial crustacean adapted to life on land. The species has been documented in North America with 81 observations recorded on iNaturalist.
Detonella
Detonella is a genus of terrestrial isopods (woodlice) in the family Detonidae, established by Lohmander in 1927. The genus contains at least two described species: Detonella papillicornis from North America and Detonella sachalina from the Russian Far East. These woodlice belong to the suborder Oniscidea, the group containing all fully terrestrial isopods.
Elumoides
Elumoides is a genus of terrestrial isopods in the family Eubelidae, established by Taiti and Ferrara in 1983. These woodlice belong to the suborder Oniscidea, representing a group of fully terrestrial crustaceans. The genus is part of the diverse isopod fauna found in tropical and subtropical regions.
Floridoscia fusca
Florida Rufous Woodlouse
Floridoscia fusca is a terrestrial isopod species in the family Philosciidae, commonly known as the Florida Rufous Woodlouse. It is native to North America and belongs to the suborder Oniscidea, which encompasses the majority of terrestrial isopods. The species was described by Schultz and Johnson in 1984.
Trachelipodidae
Trachelipodid Woodlice
Trachelipodidae is a family of terrestrial isopods (woodlice) within the suborder Oniscidea. The family was established by Strouhal in 1953 and is classified within the infraorder Orthogonopoda and parvorder Crinocheta. Members are found across Europe and North America, with documented occurrences in Denmark, Norway, Sweden, the United States (including Vermont), and Romania. The genus Trachelipus is the best-known within the family, with species such as T. trilobatus having been subject to recent distributional studies.
Tylidae
Calloused Beach Pillbugs and Heller's Isopod
Tylidae is a family of terrestrial isopods (woodlice) comprising approximately 27 species, with all but one species placed in the genus Tylos; the sole exception is Helleria brevicornis. Together with Ligiidae, Tylidae represents an early-diverging lineage among woodlouse families. Members are primarily associated with coastal sandy beach habitats in the supralittoral zone.
Tylos niveus
Snowy Calloused Beach Pillbug
Tylos niveus is a coastal isopod in the family Tylidae, first described by Budde-Lund in 1885. A 2000 redescription provided a new diagnosis for the species and documented its expanded latitudinal distribution. The species has been recorded from sandy beach habitats in Brazil, with a new occurrence reported from Taquaras, Santa Catarina, extending its known range to 27°S.
