Anatrichis
Anatrichis is a genus of ground beetles in the family Carabidae, established by LeConte in 1853. The genus belongs to the subfamily Licininae and tribe Oodini. It comprises approximately eleven described species distributed across multiple continents including Asia, Australia, and North America. Species within this genus are generally small-bodied, with several species names (lilliputana, minuta, pusilla) reflecting this diminutive size.
Atomosia pusilla
Atomosia pusilla is a small species of robber fly in the family Asilidae, described by Macquart in 1838. The genus Atomosia is characterized by species with reduced wing venation and typically small body size compared to other asilids. This species belongs to the subfamily Asilinae, one of the most diverse lineages of robber flies. Like other members of its family, it is a predatory fly that captures other insects in flight.
Attidops cutleri
Attidops cutleri is a small jumping spider in the family Salticidae, first described by Edwards in 1999. The species is known from limited observations, with only 8 documented records on iNaturalist. It occurs in the southern United States and Mexico. Like other salticids, it possesses excellent vision and hunts by stalking prey rather than building webs.
Ceratinopsis nigripalpis
Ceratinopsis nigripalpis is a species of dwarf spider in the family Linyphiidae, first described by Emerton in 1882. It is one of numerous small-bodied spiders in the genus Ceratinopsis, which are characterized by their sheet-web building behavior. The species is known from the United States and Canada.
Hilaira herniosa
Hilaira herniosa is a species of sheet-web weaving spider in the family Linyphiidae, one of the largest families of spiders. First described by Tamerlan Thorell in 1875 under the name Erigone herniosa, this small-bodied spider has a documented distribution spanning the Holarctic region, including northern Europe, Asia, and North America. The species inhabits moist, cool environments typical of many linyphiid spiders. Specific details regarding its biology and ecology remain limited in published literature.
Melanoplus infantilis
little spur-throat grasshopper, tiny spur-throat grasshopper
Melanoplus infantilis is a small spur-throated grasshopper in the family Acrididae. The species is distinguished by its diminutive size relative to other Melanoplus species. It occurs in western North America, with documented presence in Colorado. As a member of the genus Melanoplus, it possesses the characteristic spur on the ventral surface of the throat that defines this species group.
Pocobletus coroniger
Pocobletus coroniger is a species of sheet-web weaving spider in the family Linyphiidae, described by Eugène Simon in 1894. It belongs to a genus of small-bodied spiders found in the Neotropical region. The species has been recorded from scattered localities across Central America and northern South America, with some records from the southern United States. Like other linyphiids, it constructs flat, horizontal sheet webs with a retreat area. Very little is known of its specific biology or ecology.
Tidesmus
Tidesmus is a genus of small-bodied millipedes in the family Macrosternodesmidae, order Polydesmida. The genus was revised in 2007, with Phreatodesmus and Oodedesmus synonymized under it. It currently contains four valid species distributed in the southwestern United States and northwestern Mexico. The type species is T. episcopus Chamberlin, 1943.
Tinus
nursery web spider
Tinus is a genus of nursery web spiders in the family Pisauridae, established by F. O. Pickard-Cambridge in 1901. The genus includes small-bodied species that are notably smaller than most other pisaurid genera such as Dolomedes and Pisaurina. Tinus peregrinus is the best-documented species, known from the southwestern United States and northern Mexico. Members of this genus prefer vertical surfaces and are often found near water edges.
