Taxonomy Sisurcana olivobrunnea was formally described by the Polish entomologist Józef Razowski and the Polish entomologist Janusz Wojtusiak in 2010 based on a female collected from Pampa Hermosa National Sanctuary in Peru. Although the type locality was incorrectly recorded to be in the department of Pasco, the sanctuary is actually located in the department of Junín, a fact noted correctly elsewhere in the describing paper. The authors wrote that the specific epithet is derived from the Latin words meaning "olive-gray", referring to the moth's color, but this is also a typo for the specific epithet olivogrisea.
