Perizoma is a of geometer moths comprising over 150 , with a predominantly Northern Hemisphere distribution. It serves as the type genus of the tribe Perizomini within the Larentiinae. Species are commonly known as rivulets or carpets. The genus was established by Jacob Hübner in 1825 and has undergone taxonomic revision, with some related genera (Gagitodes, Martania, Mesotype) now included by some authorities. Several species have been introduced outside their native ranges, including P. alchemillata in Newfoundland.

Identification

Identification to level requires examination of genitalia , particularly for closely related species such as P. barrassoi and P. incultaria, which show correlated differential features in male and female genitalia. using the COI gene and nuclear genomic data (ddRAD sequencing) has been employed to distinguish cryptic species. The is distinguished from related Larentiinae by wing pattern and body proportions, though specific diagnostic features for the genus as a whole are not well-documented in available sources.

Distribution

Northern Hemisphere, with approximately 14 recorded in Europe. Specific documented ranges include: Alps, Pyrenees, Carpathians, Dinaric mountains, and central Italy. Perizoma alchemillata, native to Europe, has been introduced to Newfoundland, Canada, where it was first recorded in 1954 and has since spread throughout the island.

Human Relevance

Perizoma alchemillata has been documented as an introduced in Newfoundland, representing a case study in island and range expansion. sequences have been published for P. flavofasciatum (Sandy Carpet) and P. affinitatum (Rivulet) as part of the Darwin Tree of Life project, contributing to lepidopteran genomic resources.
