Symmocinae
Gozmány, 1957
Genus Guides
5Symmocinae is a of small within the Autostichidae (superfamily Gelechioidea). The group has undergone repeated taxonomic reclassification, having been treated historically as a tribe within Blastobasidae, as a separate family Symmocidae, or united with Holcopogonidae. Modern molecular and morphological evidence supports its current placement within Autostichidae, though some authorities recognize it as a distinct family pending further phylogenetic study. The subfamily is primarily distributed across the Palearctic region and Africa.

Identification
Symmocinae are distinguished from related gelechioid groups by genitalic characters and wing venation patterns that align them with Autostichidae rather than Blastobasidae or Oecophoridae. The group was historically divided into two informal clusters: one centered on the Oegoconia (sometimes treated as Oegoconiinae or Oegoconiini) and another centered on Symmoca. Separation from similar small gelechioid moths requires microscopic examination of wing structure and male genitalia; field identification to level is generally impractical.

Distribution
Primarily Palearctic and Afrotropical regions. Records indicate presence across Europe, North Africa, and sub-Saharan Africa. Specific associations within these regions remain poorly documented.
Similar Taxa
- BlastobasidaeHistorically treated as close relatives or inclusive ; Symmocinae separated based on genitalic and molecular characters, though some classifications still merge them.
- Oecophoridae (including Xyloryctinae)Alternative historical placement; Symmocinae differs in wing venation and genitalic structure, and molecular data do not support close relationship with this .
- HolcopogonidaePreviously united with Symmocinae in some treatments as combined Autostichidae; now generally treated as separate within Autostichidae.
- Oegoconiinae/OegoconiiniInformal group centered on Oegoconia, historically treated as either separate tribe within Symmocidae or as subdivision of Symmocinae; distinction based on genitalic characters of type genera.

Taxonomic instability
The classification of Symmocinae has shifted repeatedly between , , and tribal rank across different taxonomic treatments. Molecular phylogenetic analyses have reinstated family-level recognition (Symmocidae) in some recent works, though Catalogue of Life and NCBI currently place it as subfamily of Autostichidae. The group's relationships within Gelechioidea remain essentially unresolved.
