Poecilus diplophryus
Poecilus diplophryus is a species of ground beetle in the family Carabidae, first described by Chaudoir in 1876. It belongs to a genus of small to medium-sized carabid beetles commonly found in agricultural and open habitats. The species has been documented in North and Middle America, with records from the United States. Like other Poecilus species, it is likely a ground-dwelling predator sensitive to soil disturbance regimes.

Polleniidae
cluster flies
Polleniidae is a family of calyptrate flies in the order Diptera, commonly known as "cluster flies." The family was elevated from subfamily rank within Calliphoridae to full family status in 2019 based on phylogenetic evidence. It comprises approximately 150 species in eight genera, with Pollenia being the most diverse and widespread genus containing about 95 species. Members are primarily soil-dwelling and develop as endoparasitoids of earthworms.

Procampodeidae
Procampodeidae is a family of two-pronged bristletails in the order Diplura, class Entognatha. Members of this family are small, soil-dwelling hexapods with reduced or absent eyes and characteristic paired caudal appendages. The family was established by Silvestri in 1948 and belongs to the suborder Rhabdura. Procampodeidae represents one of several families within the campodeoid lineage of diplurans.

Proctotrupidae
Proctotrupidae is a family of small parasitoid wasps in the superfamily Proctotrupoidea, comprising approximately 400 described species across more than 30 genera with an estimated total diversity of around 675-1200 species. Members are primarily endoparasitoids of coleopteran larvae, particularly in families Carabidae, Staphylinidae, and Elateridae, though some genera parasitize fungus gnats (Mycetophilidae, Sciaridae) and concealer moths (Oecophoridae). Females in many species are wingless and soil-dwelling, capable of detecting host larvae in burrows. The family has a cosmopolitan distribution with notable Gondwanan relict elements in the subfamily Austroserphinae.

Pterocheilus hirsutipennis
A solitary mason wasp in the subfamily Eumeninae, Pterocheilus hirsutipennis is one of approximately 40 North American species in this genus. Like other Pterocheilus, females are fossorial, excavating subterranean burrows in sandy or soft soils rather than using pre-existing cavities or building mud nests. The species was described by Bohart in 1940 and is part of a genus whose members are most diverse in the southwestern United States. Most species biology remains poorly documented.

Rhipiceridae
Cicada-Parasite Beetles
Rhipiceridae is a family of beetles specialized as parasitoids of cicada nymphs. Larvae exhibit hypermetamorphosis, with mobile planidial first instars that actively locate and penetrate underground cicada nymphs, developing as endoparasitoids until host death. Adults display pronounced sexual dimorphism: males possess large flabellate antennae with approximately 30,000 sensilla placodea for detecting chemical cues, while females have compact bodies with simple antennae bearing around 100 sensilla. The family comprises seven genera and approximately 100 described species divided into two subfamilies: Rhipicerinae (Australia, New Caledonia, Chile) and Sandalinae (Americas, Africa, Europe, Asia).

Trematuridae
Trematuridae is a family of soil-dwelling mites in the suborder Uropodina, characterized by a pear-shaped idiosoma and distinctive morphological features including dorsal shield notching and specialized cheliceral dentition. The family has a worldwide distribution with maximal diversity in tropical rain forests. Members have been documented in association with insect hosts, including the red palm weevil, and are studied for potential biological control applications. Reproductive behaviors including pre-ovipositional, ovipositional, and mating behaviors have been described for species such as Trichouropoda ovalis.

Trimorus
Trimorus is a genus of minute parasitoid wasps in the subfamily Teleasinae, family Scelionidae. These wasps are egg parasitoids of ground beetles (Carabidae), with females laying eggs inside beetle eggs. The genus is highly diverse, with approximately 389 described species worldwide, though many more likely remain undescribed. Members exhibit striking sexual dimorphism and wing polymorphism, with both sexes showing variation from fully winged to completely wingless forms.

Trogulidae
Trogulid Harvestmen
Trogulidae is a family of harvestmen (order Opiliones) comprising approximately 65 extant species across five genera: Anarthrotarsus, Anelasmocephalus, Calathocratus, Kofiniotis, and Trogulus. Members are characterized by short legs, flattened leathery bodies, and a distinctive habit of adhering soil particles to their bodies for camouflage. The family is primarily distributed in western and southern Europe, extending to western North Africa, the Levant, the Caucasus, and northern Iran. One species, Trogulus tricarinatus, has been introduced to eastern North America. The family includes the only Trogulidae species in Ireland, Anelasmocephalus cambridgei, which has a specialized life history involving egg-laying in empty snail shells.

Typhlobius
Typhlobius is a genus of lithobiid centipedes established by Chamberlin in 1922. These centipedes belong to the order Lithobiomorpha, characterized by having 15 pairs of legs in adults. The genus is distinguished by adaptations to subterranean environments, including reduced or absent eyes. Species within this genus are poorly known, with limited published ecological or biological data available.

Veigaiidae
Veigaiidae is a family of free-living predatory mites in the order Mesostigmata. They inhabit soil and decaying organic matter, with some species specialized for rocky shorelines. The genus Veigaia is particularly widespread in the Holarctic Region.

Zuma
harvestman
Zuma is a genus of harvestmen (arachnids in the order Opiliones) established by Goodnight & Goodnight in 1942. It belongs to the family Paranonychidae, a group of small, cryptic harvestmen often found in moist microhabitats. The genus is part of the diverse Laniatores suborder, characterized by relatively short legs and compact bodies compared to other harvestman groups.

Zuma tioga
Zuma tioga is an armoured harvestman (order Opiliones) described by Briggs in 1971. It belongs to the family Paranonychidae within the infraorder Insidiatores. The species is known from North America, though specific locality details beyond this broad region are not well documented. Like other members of its family, it is a small, soil-dwelling arachnid with a heavily sclerotized body.

Zygona
Zygona is a genus of soil-dwelling centipedes in the family Geophilidae, first described by Chamberlin in 1960. Members of this genus are elongate, multi-legged arthropods characteristic of the order Geophilomorpha. The genus is poorly documented in scientific literature, with minimal published information on its species composition or biology. A single observation exists on iNaturalist, suggesting it is rarely encountered or underreported.

Zygoneura
Zygoneura is a genus of small flies in the family Sciaridae, commonly known as dark-winged fungus gnats. The genus was established by Meigen in 1830 and is currently recognized as valid within the Diptera. Species in this genus are part of a diverse group of mycophagous insects associated with decaying organic matter and fungal substrates.
