Psaphidina
Genus Guides
6Psaphidina is a subtribe within the tribe Psaphidini, Psaphidinae, and Noctuidae. It comprises a group of owlet moth primarily found in the Americas. The subtribe is distinguished by specific morphological characteristics of the male and female genitalia, which form the basis of its taxonomic delimitation. Members are generally medium-sized noctuids with relatively stout bodies. The subtribe has been subject to taxonomic revision as molecular and morphological studies continue to clarify relationships within the Psaphidini.

Identification
Separation from other subtribes within Psaphidini relies on genitalic , particularly the structure of the male valve and , and female ductus bursae. External morphology alone is generally insufficient for definitive subtribe-level identification; dissection and examination of genitalia are typically required. within Psaphidina often exhibit relatively uniform forewing patterns with muted brown, gray, or ochre coloration, but this overlaps substantially with other noctuid groups.

Distribution
Primarily distributed across the Americas, with documented occurrence in North America, Central America, and South America. Specific range boundaries at the subtribe level are not comprehensively mapped due to ongoing taxonomic refinement.

Taxonomic History
The subtribe Psaphidina was established based on phylogenetic analysis of morphological characters, particularly genitalia. Its composition has been modified as -level revisions and molecular studies have progressed. The subtribe is part of a broader reorganization of the formerly polyphyletic 'Cuculliinae' complex within Noctuidae.
Research Needs
Comprehensive molecular phylogenetic analysis of Psaphidini, including dense sampling of Psaphidina, would help clarify limits and validate current subtribe boundaries. data for most species remain poorly documented.
