Paraona was erected by Frederic Moore in 1878 around the species originally described as Crambomorpha splendens by Arthur Gardiner Butler in 1877.

[3] This classification was subsequently followed by Jeremy Daniel Holloway in 2001 in Part 7 of his book series The Moths of Borneo.

[1] In 2012, the genus was restored by Vladimir Dubatolov, Kishida and Min Wang, based on dissimilarity of the male genitalia of Paraona's type species, Crambomorpha splendens, to those of Macrobrochis.

[1] In 2024, the genus was once again synonymized with Macrobrochis, this time by Anton Volynkin, who stated that the 2012 restoration of the genus was based on a specimen held by Museum Witt Munich "identified by an unknown identifier as 'Paraona splendens'" and which is "dissimilar to the illustrations of P. splendens" by both the generic taxon author Frederic Moore and those by George Hampson.

He concluded the specimen, rather than represent Paraona splendens, was instead a different, previously undescribed species he named Murmyshia obscuria.
