Acantholeria
Acantholeria is a genus of small flies in the family Heleomyzidae, established by Garrett in 1921. The genus is poorly known, with limited published information on its species diversity, biology, and ecology. Records suggest it occurs in North America, though specific details remain sparse.
Belosta
Belosta is a genus of small, slender flies in the family Scenopinidae, commonly known as window flies. The genus was established by Hardy in 1944 and is classified within the tribe Metatrichiini. Members of this genus are part of a family characterized by their distinctive wing venation and predatory habits as larvae. The genus is poorly documented in public sources, with limited species-level information available.
Berninelsonius
Berninelsonius is a genus of click beetles (family Elateridae) established by Leseigneur in 1970. The genus is poorly known, with only three documented observations on iNaturalist and limited published information. Its members share the characteristic body plan of elaterid beetles, including the pronotal structure that enables the clicking mechanism. The genus appears to be restricted to northern Europe, with records from Norway and Sweden.
Bromleyus
Bromleyus is a genus of robber flies (family Asilidae) established by Hardy in 1944 or 1945. As a member of the diverse Asilidae family, species in this genus are predatory flies. The genus is recognized in major taxonomic databases but appears to be poorly known, with no species-level records in GBIF or observations in iNaturalist.
Conisattus
Conisattus is a genus of darkling beetles (family Tenebrionidae) described by Casey in 1895. The genus is poorly documented, with minimal published information on its biology and morphology. It appears to be restricted to the Nearctic region. The genus contains few known species and has received limited taxonomic study.
Dendrocranulus
Dendrocranulus is a genus of weevils in the family Curculionidae, established by Schedl in 1938. The genus is poorly known, with minimal published literature and very few documented observations. Based on its taxonomic placement within Curculionidae, members are likely small to medium-sized beetles with the characteristic elongated snout (rostrum) typical of weevils. The genus name suggests an association with trees ('dendro-' meaning tree, 'cranulus' possibly referring to the head or a small structure).
Doryctinus
Doryctinus is a genus of parasitoid wasps in the family Braconidae, subfamily Doryctinae. These wasps are part of a diverse group of koinobiont endoparasitoids that attack concealed hosts, particularly wood-boring beetle larvae. The genus was established by Roman in 1910 and remains poorly known, with limited species-level documentation and few observational records.
Eusama
Eusama is a genus of leafhoppers in the family Cicadellidae, tribe Platymetopiini, established by Oman in 1949. Members of this genus are part of the diverse Deltocephalinae subfamily, one of the largest groups within leafhoppers. The genus is poorly known, with minimal published biological information and few documented observations.
Fania connectus
Fania connectus is a small cossid moth described in 1916 from Texas. The species exhibits distinctive wing patterning with contrasting smoky brown and silvery white areas separated by dark transverse markings. Adults are active in both spring and fall, suggesting a bivoltine life cycle. The genus Fania is poorly known, with limited biological data available.
Gyalostethus
Gyalostethus is a genus of flat-backed millipedes in the family Xystodesmidae, described by Hoffman in 1965. It belongs to the tribe Rhysodesmini and is part of the diverse order Polydesmida, which contains many North American millipede species. The genus is poorly documented in scientific literature, with limited species-level information available.
Helcostizus
Helcostizus is a genus of ichneumon wasps in the family Ichneumonidae, first described by Förster in 1869. The genus is poorly studied, with limited published information on its biology and ecology. Records indicate presence in Scandinavia. Species within this genus are parasitoid wasps, though specific host associations remain undocumented.
Hoppingiana
Hoppingiana is a genus of soft-bodied beetles in the family Melyridae, established by Blaisdell in 1924. The genus is poorly documented in scientific literature, with only 11 observations recorded on iNaturalist as of the available data. Like other melyrid beetles, members of this genus likely exhibit the characteristic soft elytra and flexible body form typical of the family. The genus name honors an entomologist, following the common practice of patronymic nomenclature in coleopteran taxonomy.
Jamesomyia
Jamesomyia is a small genus of tephritid fruit flies in the tribe Noeetini, established by Quisenberry in 1949. The genus contains at least one recognized species, Jamesomyia geminata, originally described by Loew in 1862. As a member of the Tephritidae family, species in this genus likely possess the characteristic wing patterning and fruit-associated biology typical of true fruit flies, though specific details remain poorly documented.
Lachnochaitophorus
Lachnochaitophorus is a genus of aphids in the family Aphididae, tribe Myzocallidini. It was established by Granovsky in 1933. Members of this genus are small, sap-feeding insects that infest woody plants. The genus is poorly documented in scientific literature, with limited species-level information available.
Microdonia
Microdonia is a genus of rove beetles in the family Staphylinidae, established by Casey in 1893. The genus contains at least four described species distributed in North America. Members belong to the tribe Lomechusini within the subfamily Aleocharinae, a group known for myrmecophilous (ant-associated) associations. The genus remains poorly known, with limited ecological and behavioral documentation.
Myelaphus
Myelaphus is a genus of robber flies in the family Asilidae, established by Bigot in 1882. The genus contains approximately six described species distributed primarily in Asia. Members of this genus are predatory dipterans that hunt other insects in flight.
Nigridonus
Nigridonus is a genus of leafhoppers in the family Cicadellidae, subfamily Deltocephalinae, tribe Platymetopiini. Established by Oman in 1949, this genus belongs to a diverse group of sap-feeding insects within the order Hemiptera. Members of this genus are poorly documented in scientific literature, with limited published information on their biology and ecology.
Onychobaris
Onychobaris is a genus of flower weevils in the family Curculionidae, established by John Lawrence LeConte in 1876. The genus contains more than 40 described species distributed across North America. Members are associated with flowers and vegetation, though specific ecological details for most species remain poorly documented.
Pentanodes
Pentanodes is a genus of longhorn beetles (Cerambycidae) established by Schaeffer in 1904. The genus belongs to the tribe Tillomorphini within the subfamily Cerambycinae. Two species are currently recognized: Pentanodes albofasciatus (Fisher, 1932) and Pentanodes dietzii (Schaeffer, 1904). The genus is poorly documented in scientific literature, with limited information available on its biology and ecology.
