Genus Guides
1Tortricini is a tribe of tortrix moths ( Tortricidae) established by Latreille in 1803. The tribe contains numerous distributed across tropical and temperate regions worldwide. Australian representatives include 16 in six genera, divisible into the Phricanthes group and Eboda group. Members exhibit characteristic tortricid with specialized genital structures used in taxonomic identification.

Identification
Tortricini possess the general tortricid wing posture at rest, with wings held roof-like over the body. Diagnostic features include specific venation patterns and genitalia structures; male genitalia feature distinctive valvae and configurations, while female genitalia show characteristic signum and ductus bursae . The Australian fauna separates into two groups: Phricanthes group (Phricanthes, Scolioplecta) and Eboda group (Amboyna, Anameristes, Eboda, Asterolepis).

Habitat
vary by . Australian Phricanthes associate with Dilleniaceae plants. Scolioplecta species occur in widely scattered localities suggesting broad habitat . Anameristes inhabits north Queensland rainforest. Amboyna and Asterolepis species occupy Cape York Peninsula and New Guinea transition zones. Cornuticlava and Epitrichosma species in related tribes occur in northern Queensland rainforest and southwestern Australia.
Distribution
distribution with strong representation in tropical regions. Documented from Nigeria, Nepal, Oriental region, Australia, New Guinea, and Indo-Malayan areas. Australian fauna includes 16 across six , with some species exhibiting wide distributions beyond Australia (Phricanthes species).
Diet
Larvae of Phricanthes feed on plants in Dilleniaceae. Proselena larvae are leaf miners in Bursaria. Other Tortricini larval diets remain insufficiently documented.

Similar Taxa
- SchoenoteniniCo-occurs in Tortricinae; distinguished by larval and genitalia structure. Schoenotenini larvae include leaf miners, bark tunnelers, and gall borers rather than free-feeding tortricine larvae.
- ChlidanotiniCo-occurs in Tortricinae; separated by wing venation, genitalia , and larval characteristics. Australian Chlidanotini include five in four with distinct morphological features.
- CnephasiiniAnother tribe in Tortricinae; Tortricini distinguished by male genitalia with reduced socii and different structure.

Australian tribal composition
The Australian Tortricinae include three tribes: Tortricini (16 , 6 ), Schoenotenini (19 species, 7 genera), and Chlidanotini (5 species, 4 genera). Tortricini are the second most diverse tribe in this region.
Taxonomic history
The tribe has undergone extensive revision by Józef Razowski, who described numerous tropical and Oriental and established modern generic concepts.
