Taxonomy Claduncaria minisignaria was formally described as Argyrotaenia minisignaria by the Polish entomologist Józef Razowski in 1999 based on a female collected from northeastern Los Arroyos sector of the Sierra de Bahoruco National Park. In 2000, Razowski and Becker described A. m. chalarostium as a novel subspecies based on a female specimen from Jamaica. A 2020 review of the taxonomy of the Caribbean Archipini found that these two taxa were better treated as distinct species and raised chalarostium to species status. They additionally noted that Razowski had mistakenly identified a male specimen of A. minisignaria as belonging to A. mesosignaria. They moved A. minisignaria to the genus Claduncaria, alongside A. mesosignaria and A. chalarostium, based on the morphology of its male genitalia. C. minisignaria is most closely related to C. mesosignaria.
