- Archirhoe neomexicana(New Mexico Carpet Moth)
Archirhoe is a of geometer moths in the Geometridae, Larentiinae, established by Herbulot in 1951. The genus contains four described distributed in North America: A. associata, A. indefinata, A. multipunctata, and A. neomexicana. These are part of the diverse carpet moth group, though specific ecological and biological details remain poorly documented in the scientific literature.

Identification
Archirhoe can be distinguished from other Larentiinae by wing pattern characteristics, though precise diagnostic features require examination of genitalia . The genus is characterized by relatively broad, rounded forewings with intricate patterns of lines and spots. Species-level identification relies on subtle differences in wing pattern elements, particularly the configuration of the postmedial line and discal spot size and position. A. multipunctata is distinguished by multiple small discal spots, while A. neomexicana shows more uniform dark shading.

Distribution
North America. occur across the United States and southern Canada, with A. neomexicana ranging from New Mexico and Arizona northward, A. multipunctata found in the Pacific Northwest and Rocky Mountain regions, A. indefinata distributed in the eastern United States, and A. associata recorded from the Great Lakes region and northeastern North America.
Similar Taxa
- EuphyiaSimilar wing shape and pattern in Larentiinae, but Euphyia typically have more angular forewing apices and different genitalia structure.
- XanthorhoeOverlapping color patterns of brown and orange bands, but Xanthorhoe generally show more pronounced transverse banding and different male genitalia .
- CostaconvexaSimilar ground coloration and wing shape; separation requires examination of wing venation and genitalia characteristics.

Taxonomic history
The was erected by French lepidopterist Claude Herbulot in 1951 to accommodate previously placed in other genera, particularly those formerly assigned to Cidaria or related carpet moth genera. The type species is Archirhoe neomexicana (originally described as Cidaria neomexicana by Hulst in 1896).
Species composition
The four recognized were all described between 1896 and 1941, with three originally placed in other before transfer to Archirhoe. No additional species have been described since the genus establishment, suggesting either genuine species rarity or taxonomic neglect.
