Pseudoscorpiones
pseudoscorpions, false scorpions, book scorpions
Pseudoscorpions are tiny arachnids, most under 5 mm in length, superficially resembling scorpions but lacking a stinger and elongated tail. They are among the oldest terrestrial colonizers, with fossils dating to the Middle Devonian (ca. 390 million years ago). Despite their ancient lineage, they exhibit remarkable morphological stasis, with even Devonian fossils appearing modern. Most species inhabit concealed microhabitats such as beneath bark, in leaf litter, soil, caves, or mammal nests, making them seldom encountered despite being fairly common. They are predatory, seizing small invertebrate prey with venomous pincer-like pedipalps.
Schizoptera rileyi
Schizoptera rileyi is a species of minute litter bug in the family Schizopteridae, described in 2018. Members of this family are among the smallest true bugs, typically inhabiting leaf litter and soil habitats. The species epithet honors Edward Riley, a prolific coleopterist and collector. The genus Schizoptera belongs to the infraorder Dipsocoromorpha, a group of cryptic, ground-dwelling true bugs that are poorly known due to their small size and concealed habits.
Soa
Soa is a genus of booklice in the family Lepidopsocidae, order Psocodea. These small, wingless insects inhabit sheltered microhabitats and feed on organic debris. The genus was established by Enderlein in 1904 and is currently accepted in modern classifications.
