Teleiodes
Sattler, 1960
Teleiodes is a of micro- in the Gelechiidae, established by Sattler in 1960. The genus comprises approximately 25 accepted distributed primarily across the Palearctic region, with notable diversity in Europe and East Asia. The type species, Teleiodes luculella (Crescent Groundling), has been subject to genomic study, revealing a 454.5 Mb . Species in this genus are generally small moths with forewing lengths around 5–6 mm, often characterized by distinctive wing patterns including pale costal blotches.

Identification
Members of Teleiodes can be distinguished from related gelechiid by genitalia , particularly valvae structure; several epithets (brevivalva, linearivalvata, cyrtocostella) reference these diagnostic features. Wing patterns often include pale or white costal markings, but these vary considerably among species and are not genus-diagnostic. Accurate identification typically requires dissection and examination of male genitalia.

Distribution
Palearctic distribution with records from Europe (including Denmark, Norway, Sweden), Russia, and East Asia (China, Korea, Japan). Specific associations are documented only for individual ; for example, Teleiodes luculella occurs in oak woods in England and Wales.
Similar Taxa
- GelechiaBoth belong to Gelechiidae and share small size and general body plan; Teleiodes is distinguished by genitalia and was historically separated from Gelechia sensu lato based on these features.
- ScrobipalpaSimilar micro- habitus in Gelechiidae; Scrobipalpa often have more uniform wing coloration and different genitalia structure, particularly in male uncus and gnathos .

Genomic resources
The of Teleiodes luculella has been sequenced and assembled, providing a 454.5 Mb nuclear genome scaffolded into 30 chromosomal pseudomolecules (29 plus Z ) and a 15.32 kb mitochondrial genome. Gene annotation identified 19,943 protein-coding genes.
Taxonomic history
Numerous have been transferred out of Teleiodes to other ; the 'Former species' list includes now placed in genera such as Aproaerema, Caryocolum, and others, reflecting the historical instability of Gelechiidae classification.
