Anarsioses
Anarsioses is a genus of leafmining moths in the family Gracillariidae, established by Davis in 2019 to accommodate the species formerly known as Phyllonorycter aberrans. The genus was separated from Phyllonorycter based on distinctive morphological and molecular evidence, particularly the unusual asymmetry of the male genitalia and differences in larval biology. It is currently monotypic, containing only the type species Anarsioses aberrans.
Anarsioses aberrans
A small leafmining moth in the family Gracillariidae, originally described from North America in 1930. The species was transferred between multiple genera before molecular and morphological studies established its placement in the new genus Anarsioses, distinguished from related Phyllonorycter by asymmetrical male genitalia and distinct larval biology.
Cremastobombycia
A genus of micromoths in the family Gracillariidae, subfamily Lithocolletinae. Species are leaf miners primarily associated with Asteraceae host plants. The genus was established by Braun in 1908 and includes at least nine described species distributed across the Americas, with recent discoveries extending its range to South American high-elevation Andean habitats. Several species have been investigated for biological control of invasive plants.
Leucanthiza amphicarpeaefoliella
Leucanthiza amphicarpeaefoliella is a minute leaf-mining moth in the family Gracillariidae, described by Clemens in 1859. The species occurs in northeastern North America, with records from Ontario and Québec in Canada and several eastern and midwestern U.S. states. Adults are small with a wingspan of approximately 8 mm. The larvae are specialized leaf miners on Amphicarpaea bracteata, a leguminous vine.
Macrosaccus coursetiae
Macrosaccus coursetiae is a small moth in the family Gracillariidae, described from Arizona in 2017. It is the sixth species in the genus Macrosaccus. The larvae are leaf miners that feed inside the leaves of Coursetia glandulosa (Fabaceae). The parasitoid wasp Chrysocharis walleyi (Eulophidae) has been reared from its leaf mines.
Phyllonorycter mariaeella
Phyllonorycter mariaeella is a micro-moth in the family Gracillariidae, commonly known as leaf blotch miner moths. The species is known from limited localities in Canada and the United States. Larvae are leaf miners that feed on species of Symphoricarpos (coralberry/snowberry). Adults are tiny, with a wingspan of 8-8.5 mm.
