Phaegoptera albimacula is a species of moth belonging to the family Erebidae and the subfamily Arctiinae (commonly known as tiger moths). The species was formally described by the British entomologist E. Dukinfield Jones in 1908.
This taxon is not widely recognized in general literature, and it lacks comprehensive documentation in primary encyclopedic sources. According to taxonomic records, the species was described based on specimens collected in Castro, Paraná, Brazil. As a member of the genus Phaegoptera, it is classified within the subtribe Phaegopterina. The specific epithet, albimacula, is derived from Latin, where albus means "white" and macula means "spot," typically referring to the presence of white markings on the insect's wings or body.
There is currently insufficient encyclopedic information available regarding the biological life cycle, host plants, population distribution, or conservation status of Phaegoptera albimacula. Scientific data on this species remains primarily restricted to historical taxonomic catalogs and specialized lepidopterological databases.
