- Horama plumipes
Horama is a of tiger moths in the Erebidae, established by Jacob Hübner in 1819. The genus contains approximately 11 recognized distributed primarily in the Americas, with notable diversity in the Caribbean region. Several species exhibit striking mimicry, most famously H. panthalon, known as the Texas wasp moth. The genus has undergone taxonomic revision, with some species formerly placed here reassigned to related genera such as Poliopastea.

Identification
in Horama are distinguished from other tiger moths by their -like appearance, featuring narrow, elongated wings and a slender body with contrasting color patterns of black, orange, and yellow. The can be separated from the similar genus Poliopastea by genitalic characters and subtle differences in wing venation. Specific species identification requires examination of male genitalia and detailed wing pattern analysis; H. panthalon is particularly recognizable by its bold transverse orange bands on a black background.

Taxonomic History
The was reviewed by Dietz and Duckworth in 1976, resulting in the reestablishment of Poliopastea as a valid genus and clarification of boundaries. McCabe (1992) revised Caribbean species, describing two new species and documenting mimicry complexes.
