Amiota
Amiota is a genus of small flies in the family Drosophilidae, established by Loew in 1862. The genus contains over 100 described species with a cosmopolitan distribution, though it exhibits particularly high diversity in East Asia. Southwestern China has been hypothesized as a possible center of origin and diversification. Some species serve as intermediate hosts and vectors for parasites, including Amiota okadai which transmits the zoonotic nematode Thelazia callipaeda.
Ancylosis
snout moths
Ancylosis is a genus of snout moths in the family Pyralidae, subfamily Phycitinae, established by Philipp Christoph Zeller in 1839. The genus exhibits broad geographic distribution across multiple continents, with species recorded from Africa, Europe, Asia, Australia, and the Americas. Taxonomic revision work in recent years has clarified species boundaries, established new synonyms, and reinstated several previously synonymized species. The genus contains multiple subgenera including Ancylosis, Heterographis, Cabotia, and Syria, though some species remain unassigned.
Anyphaena dixiana
ghost spider
Anyphaena dixiana is a species of ghost spider in the family Anyphaenidae. It belongs to the celer species group within the genus Anyphaena. Originally described from the United States, the species has subsequently been recorded from Mexico. As with other anyphaenids, it is likely nocturnally active.
Archipini
Archipini is the largest tribe in the Tortricinae subfamily, comprising over 1,600 described species across approximately 150 genera. Members are found in all ecoregions globally, though with notably reduced diversity in the Neotropical realm. The tribe contains numerous economically significant agricultural and forestry pests, including the light brown apple moth (Epiphyas postvittana) and spruce budworms (Choristoneura species). Larvae are frequently polyphagous. Phylogenetic evidence supports an Australasian origin for the tribe.
Argyriini
Argyriini is a tribe of crambid snout moths within the subfamily Crambinae. Members are small to medium-sized moths with relatively inconspicuous coloration. The tribe is distinguished by specific morphological features of the male genitalia, particularly the structure of the phallus and juxta. Many species are associated with grassland and wetland habitats where their larval hosts grow.
Astrotischeria
trumpet leaf-miner moths
Astrotischeria is a New World genus of micromoth leaf miners in the family Tischeriidae, described in 2003. The genus is distributed across the Americas from the United States through the Caribbean and Central America to South America. Larvae are leaf miners, with most studied species associated with host plants in the Asteraceae family, particularly the subfamily Asteroideae. Some species exhibit a distinctive three-lobed male genital valva, a novel character for Tischeriidae. The genus includes at least 21 described species, with new species continuing to be discovered in the Neotropics.
Autostichidae
Autostichidae is a family of small moths in the superfamily Gelechioidea, comprising approximately 600 described species worldwide. The family is divided into six subfamilies: Autostichinae, Deocloninae, Glyphidocerinae, Holcopogoninae, Oegoconiinae, and Symmocinae. Species-level taxonomy has been extensively studied in Asia, particularly for the genus Meleonoma in China, where over 70 new species have been described in recent years. The family exhibits considerable morphological diversity in genitalia structure, which serves as a primary diagnostic feature for species identification.
Elachistinae
grass-miner moths
Elachistinae is a subfamily of small moths in the family Elachistidae, superfamily Gelechioidea. The subfamily contains approximately 805 valid species placed in 10 genera, with the genus Elachista being the most diverse. Species are predominantly leaf miners, with larvae feeding on monocotyledonous plants, especially sedges (Cyperaceae) and grasses (Poaceae). The subfamily has a worldwide distribution with significant diversity in the Holarctic region. Many species show narrow host plant associations and some exhibit vicariant distribution patterns.
Leucaniini
Wainscot Moths
Leucaniini is a tribe of noctuid moths within the subfamily Noctuinae, commonly known as wainscot moths. The tribe contains at least 40 described species distributed across multiple genera including Leucania, Mythimna, and Tiracola. Members are nocturnal and frequently collected using light traps. Some species, particularly within Tiracola, are agricultural pests with documented economic impact.
Lozotaenia
Lozotaenia is a genus of tortricid moths in the tribe Archipini, established by Stephens in 1829. The genus was recently discovered in Taiwan with the description of Lozotaenia xiaofengkouensis Lu & Hsu sp. nov. Most species are found in the Palearctic region, particularly northern Europe. The genus comprises small to medium-sized moths with characteristic tortricid wing patterns and resting posture.
Oecleus sagittanus
Oecleus sagittanus is a species of planthopper in the family Cixiidae, described by Ball & Klingenberg in 1935. It belongs to the tribe Oecleini, a group of small to medium-sized fulgoroid insects characterized by their brachypterous or macropterous wing conditions and association with host plants. The species epithet 'sagittanus' refers to an arrow-like shape, likely describing a morphological feature of the male genitalia or wing structure. Like other cixiids, it is presumed to feed on plant phloem sap using piercing-sucking mouthparts.
Rhegmoclematini
Rhegmoclematini is a tribe of minute black scavenger flies (family Scatopsidae) within the subfamily Scatopsinae. These flies are small-bodied dipterans associated with decaying organic matter. The tribe is distinguished by morphological features of the male genitalia, particularly the structure of the claspers. Members are poorly known compared to the related tribe Scatopsini, with limited biological data available.
