Cornulactica is a genus of leaf beetles (Chrysomelidae) described by Bechyné in 1955. The genus is currently classified as doubtful in GBIF, indicating taxonomic uncertainty regarding its validity or circumscription. It belongs to the diverse family Chrysomelidae, one of the largest families of beetles, whose members are primarily herbivorous. The genus has been documented in iNaturalist with 71 observations, suggesting some level of field recognition, though detailed biological information remains limited.
Dasytastes
Dasytastes is a genus of soft-bodied beetles in the family Melyridae, first described by Casey in 1895. The genus is poorly documented and its taxonomic status is currently marked as doubtful. Only limited information exists regarding its species composition and biology. Records in biodiversity databases suggest sparse observation records, with few documented occurrences.
Dryophilodes
Dryophilodes is a genus of beetles in the family Ptinidae (spider beetles and relatives), described by Blackburn in 1891. The genus is currently marked as doubtful in taxonomic databases, indicating uncertainty about its validity or circumscription. Members of Ptinidae are generally small beetles associated with wood, stored products, or fungal habitats. The genus contains relatively few documented observations, with limited ecological and morphological data available in published literature.
Euschaefferia
Euschaefferia is a genus of beetles in the family Trogossitidae, established by Leng in 1920. The genus is currently considered doubtful in taxonomic status.

Eutricholistra
Eutricholistra is a genus of soft-winged flower beetles in the family Melyridae, established by Blaisdell in 1924. The genus is currently considered doubtful in taxonomic databases, indicating uncertain validity or placement. No observations of this genus have been recorded on iNaturalist, suggesting it is either extremely rare, poorly collected, or potentially synonymized with another genus.
Gossyparia
Gossyparia is a genus of scale insects in the family Eriococcidae, established by Signoret in 1875. The genus contains species associated with woody plants, including Gossyparia spuria, which has been studied for its parasitoid complex in Turkey. Taxonomic status of the genus is currently marked as doubtful in some databases, reflecting ongoing classification uncertainty within the Eriococcidae.
Hemiopsida
Hemiopsida is a genus of beetles in the family Eucnemidae, established by MacLeay in 1873. The genus is classified as doubtful in GBIF, indicating taxonomic uncertainty regarding its validity or circumscription. Eucnemidae, commonly known as false click beetles, are a family of elateroid beetles characterized by larvae that develop in decaying wood. Hemiopsida has minimal documentation in major biodiversity databases, with only 13 observations recorded on iNaturalist.
Kulcania
Kulcania is a genus of parasitic wasps in the family Orussidae, established by Benson in 1935. The genus is currently listed as doubtful in taxonomic databases, indicating uncertainty about its validity or distinctness from related genera. Members of Orussidae, commonly called parasitic wood wasps, are unusual among Hymenoptera as they are parasitoids of wood-boring beetle larvae rather than other wasps or bees.
Listrimorpha
Listrimorpha is a genus of soft-bodied plant beetles in the family Melyridae, established by Blaisdell in 1921. The genus is currently classified as doubtful in taxonomic databases, indicating uncertainty about its validity or distinctness from related genera. It is known from a single observation record, suggesting extreme rarity or potential synonymy with another melyrid genus.
Macrotracheliella
Macrotracheliella is a genus of minute pirate bugs in the family Anthocoridae, established by Champion in 1900. The genus is currently considered taxonomically doubtful, with limited available information regarding its constituent species and biology. It belongs to the subfamily Anthocorinae, a group of predatory true bugs commonly found in diverse terrestrial habitats.
Mitromyia
Mitromyia is a genus of stilt-legged flies (family Micropezidae) established by Cresson in 1930. Its taxonomic status is uncertain, with some sources treating it as a synonym of Taeniaptera. The genus has been rarely documented, with only 10 observations recorded on iNaturalist. As a micropezid, members likely possess the family's characteristic elongated legs and slender body form, though specific diagnostic features for the genus remain poorly characterized.
Myrmilloides
Myrmilloides is a genus of velvet ants (family Mutillidae) established by André in 1902. The genus is currently considered doubtful in GBIF taxonomy, suggesting taxonomic uncertainty or potential synonymy with other genera. As members of Mutillidae, species in this group are solitary wasps with wingless females and winged males. The genus has been recorded in iNaturalist with 143 observations, indicating some level of field recognition despite taxonomic questions.
Neodeceia
Neodeceia is a genus of small flies in the family Lauxaniidae, established by Malloch in 1924. It is currently considered a synonym of Neodecia according to Catalogue of Life, with its taxonomic status marked as doubtful in GBIF. The genus belongs to the diverse group of lauxaniid flies, which are commonly found in forested and humid environments. Little specific information is available about this particular genus due to its synonymized status.
Neolitochrus
Neolitochrus is a genus of beetles in the family Phalacridae, established by Gimmel in 2013. The genus belongs to the order Coleoptera and is currently classified with a doubtful taxonomic status in some databases. It is represented by a small number of observations, with 52 records documented on iNaturalist. Little is known about the specific biology or ecology of this genus.
Ovatus crataegarius
Hawthorn-Mint Aphid
Ovatus crataegarius, commonly known as the Hawthorn-Mint Aphid, is an aphid species in the family Aphididae.

Psilepyris
Psilepyris is a genus of insects in the order Hymenoptera, described by Kieffer in 1913. The genus is currently classified as doubtful in GBIF, indicating taxonomic uncertainty regarding its validity or placement. No family assignment is established, and the genus appears to be poorly documented in modern literature.
Temnopsophus
Temnopsophus is a genus of soft-winged flower beetles (family Melyridae) described by Horn in 1872. The genus is considered doubtful in current taxonomic databases, indicating uncertainty about its validity or circumscription. Very few observations exist, with only 11 records on iNaturalist.
