Decodes asapheus
Powell, 1980
Decodes asapheus is a of tortricid described by Jerry A. Powell in 1980. It belongs to the tribe Cnephasiini within the Tortricinae. The Decodes is to the Hawaiian Islands, and this species is one of several described from this isolated archipelago. Like other Cnephasiini, it is presumed to have a larval stage that feeds on plant material, though specific records for this species are not documented.

Identification
Decodes asapheus can be distinguished from other Decodes by genitalic , particularly the male valvae and female sterigma, as detailed in Powell's 1980 revision. The Decodes is characterized by forewing pattern elements that include a well-defined fascia and distinct discal spots. Within the tribe Cnephasiini, Decodes species typically show reduced wing markings compared to Cnephasia, with more uniform ground coloration. Accurate identification requires dissection and comparison with or original descriptions.
Distribution
Hawaiian Islands ( to this archipelago, specific island distribution not documented in available sources).
Similar Taxa
- Decodes basiplagataAnother Hawaiian in the same , distinguished by differences in forewing pattern and genitalic structure.
- Cnephasia jactatanaMember of the same tribe (Cnephasiini) with superficially similar wing pattern, but distinguished by male genitalia structure and geographic distribution (Cnephasia is primarily Palearctic).

Taxonomic history
The Decodes was established by Powell in 1980 as part of his comprehensive revision of Hawaiian Tortricidae, which remains the definitive treatment of the group. The name 'Decodes' refers to the difficulty in decoding the relationships of these prior to detailed morphological study.
