Microcorsini
Kuznetzov, 1970
Genus Guides
1Microcorsini is a tribe of tortrix moths in the Olethreutinae, first described by Kuznetzov in 1970. The tribe was originally erected for four in Olethreutinae, later transferred to Tortricinae by the same author in 1973, with subsequent treatments returning it to Olethreutinae. The genus Cryptaspasma is the primary representative, with distributed across the Neotropical region from Mexico to South America.

Identification
Microcorsini can be distinguished from other Olethreutinae tribes by genitalic , particularly the structure of the male and female genitalia. Female genitalia characteristics include specific configurations of the sterigma and signum that separate Cryptaspasma from related tortricid . The tribe has been described as morphologically generalized within Olethreutinae, exhibiting plesiomorphic traits that complicate straightforward visual identification without dissection.
Habitat
Montane and mid-elevation forest . Recorded elevations range from 140 m in lowland Amazonian sites to 3100 m in highland Rica. Specific documented habitats include cloud forest and subtropical/tropical moist forest environments.
Distribution
Neotropical region: Mexico (Tamaulipas), Rica, Panama, Brazil (Minas Gerais, Paraná, Santa Catarina, Amazonas, Rondônia), Peru (Carabaya), Ecuador, and French Guiana.

- Other Olethreutinae tribesMicrocorsini has been described as the most generalized tribe of Olethreutinae, sharing plesiomorphic morphological features with multiple related tribes; definitive separation requires examination of genitalic structures rather than external appearance.
More Details
Taxonomic instability
The tribal classification has shifted historically: originally placed in Olethreutinae (1970), transferred to Tortricinae (1973), and subsequently returned to Olethreutinae in modern treatments. This instability reflects the generalized that makes tribal assignment difficult.
Data gaps
plant relationships are entirely unknown for Microcorsini. This represents a significant gap in tortricid , as larval feeding habits have not been documented for any in the tribe.
