Absensiugum
Absensiugum is a genus of beetles in the family Eucnemidae, commonly known as false click beetles. Members of this genus are part of a group characterized by larvae that develop in decaying wood. The genus is relatively obscure with limited documented observations.
Guthriella
Guthriella is a genus of springtails in the family Isotomidae, first described by Carl Börner in 1906. The genus belongs to the order Entomobryomorpha, one of the largest and most diverse groups of Collembola. Very little published information exists on this genus, and no observations are recorded in major biodiversity databases. Its species appear to be poorly documented in modern literature.
Helops opacus
Helops opacus is a species of darkling beetle in the family Tenebrionidae, described by LeConte in 1859. Like other members of the genus Helops, it belongs to a group of darkling beetles that are not part of the well-known Eleodes genus but share the family characteristics of concealed mandibles and bead-like antennae segments. The genus Helops is relatively obscure compared to the more frequently encountered darkling beetles, and specific ecological details for H. opacus remain poorly documented in the available literature.
Hymenochara
Hymenochara is a genus of darkling beetles in the family Tenebrionidae, described by Campbell in 1978. The genus is poorly documented in scientific literature, with limited information available on its species composition, biology, and ecology. It belongs to the diverse tenebrionid lineage, which comprises predominantly detritivorous and xerophilic beetles. The genus appears to be rarely encountered, with few observations recorded in biodiversity databases.
Litasida
Litasida is a genus of darkling beetles in the family Tenebrionidae, established by Casey in 1912. The genus is poorly documented, with minimal published information available regarding its species composition, ecology, and natural history. It belongs to the diverse beetle family Tenebrionidae, which contains over 20,000 described species worldwide, many of which are adapted to arid environments. The genus appears to be restricted to the Nearctic region based on available distribution records.
Lupraea
Lupraea is a genus of leaf beetles in the family Chrysomelidae, established by Martin Jacoby in 1885. The genus belongs to the diverse beetle family Chrysomelidae, commonly known as leaf beetles, which are primarily herbivorous. Information regarding the constituent species, biology, and distribution of Lupraea remains poorly documented in available literature.
Microstagetus
Microstagetus is a genus of minute hooded beetles in the family Corylophidae, established by Wollaston in 1861. The genus is poorly known, with very few documented observations—only three records on iNaturalist as of the data cutoff. Members of this genus are among the smallest beetles, reflecting the general characteristics of Corylophidae. The scarcity of records suggests either genuine rarity, cryptic habits, or undercollecting due to their minute size.
Phlebosotera
Phlebosotera is a genus of small flies in the family Asteiidae, established by Duda in 1927. Members of this family are generally minute, delicate flies associated with decaying plant matter and fungi. The genus is poorly documented in published literature, with limited species-level information available.
Rosenus
Rosenus is a genus of leafhoppers (family Cicadellidae, subfamily Deltocephalinae) established by Oman in 1949. It belongs to the tribe Paralimnini, a group of small to medium-sized leafhoppers often associated with grassland and wetland habitats. The genus is poorly documented in public literature, with no species-level entries in major biodiversity databases and no observations recorded on iNaturalist. Distribution records from GBIF indicate presence in Norway and Sweden.
Trematopygodes
Trematopygodes is a genus of ichneumonid wasps established by Aubert in 1968. The genus belongs to the family Ichneumonidae, one of the largest families of parasitoid wasps. Very little published information exists about this genus, with only one observation documented on iNaturalist and minimal species-level documentation in major biodiversity databases. The genus name suggests a relationship to Trematopygus, a related ichneumonid genus, with the suffix -odes indicating resemblance.
