Mouralia
Walker, 1858
Species Guides
1Mouralia is a of in the Noctuidae, containing the single Mouralia tinctoides. The genus was established by Walker in 1858. Larvae are specialized feeders on plants in the family Commelinaceae, including Tradescantia and Commelina species. The species has a broad New World distribution spanning subtropical and tropical regions of the Americas.

Identification
Distinguished from other Plusiinae by a combination of wing pattern and male genitalia characteristics; precise diagnostic features require examination. As a genus, identification to genus level equates to identification (M. tinctoides).
Appearance
Wingspan approximately 44 mm. As a member of the Plusiinae, likely exhibit the characteristic forewing shape and patterning typical of looper moths, though specific morphological details for the are not well documented in available sources.
Distribution
Southeastern United States (Florida, Georgia, southeast Texas, southern California), the Antilles, Mexico, Central America, and South America (Brazil to northern Argentina, Peru).
Diet
Larvae feed on in the plant Commelinaceae. Documented include Tradescantia fluminensis, Tradescantia zebrina, and Commelina diffusa. Larvae have been successfully reared on multiple Commelinaceae species under experimental conditions.

Taxonomic history
The has remained since its description, with no additional described. Placement in Plusiinae and tribe Abrostolini reflects modern molecular and morphological phylogenetic studies.
Host plant research
Experimental studies have demonstrated that larvae can complete development on multiple Commelinaceae , suggesting potential flexibility in use despite field records from limited plant .
