Champion, 1887
Genus Guides
1Talanini is a tribe of darkling beetles (Tenebrionidae) within the Stenochiinae, established by Champion in 1887. The tribe comprises characterized by morphological features associated with the Stenochiinae lineage. The group is relatively poorly documented in scientific literature, with limited -level information available. Talanini is distinguished from related tribes within Stenochiinae by specific combinations of tarsal and antennal structures, though precise diagnostic boundaries remain under study.

Identification
Talanini is distinguished from other Stenochiinae tribes primarily by tarsal formula and antennal . Members of this tribe exhibit tarsal structures consistent with the Stenochiinae , with specific segment counts and proportions that separate them from the tribes Stenochiini and Cnodalonini. Antennal club structure and the degree of pronotal constriction also serve as diagnostic features. Accurate identification to tribe level requires examination of specimens under magnification; the tribe is not reliably distinguishable from field observations alone.
Distribution
Talanini has been documented in the Neotropical region, with records concentrated in Central and South America. The tribe's distribution aligns with the broader range of Stenochiinae, which is predominantly tropical and subtropical. Specific country-level records are sparse in published literature.

Taxonomic Status
Talanini was established by Champion in 1887 but has received limited subsequent taxonomic attention. The tribal boundaries and included have not been comprehensively revised in modern phylogenetic frameworks. The Catalogue of Life and other aggregators list the tribe as accepted, but detailed systematic studies are lacking.
Observation Data
iNaturalist records 58 observations identified to this tribe, suggesting some field recognition, though these identifications may represent provisional assignments pending expert verification. The low observation count relative to related tribes indicates either genuine rarity, cryptic habits, or underdetection.
