"Formosibittacus macularis" is known only from one fossil, the holotype, specimen numbers "CNU-M-NN2007001-1" and "CNU-M-NN2007001-2" for the part and counterpart respectively. The specimen is composed of an almost complete specimen of unidentified sex and is preserved as a compression fossil in sedimentary rock. The fossil was recovered from outcrops of the Jiulongshan Formation exposed in the Wuhua Township by Fang Liang. The type specimen is currently preserved in the Key Lab of Insect Evolution &amp; Environmental Changes collections housed in the Capital Normal University, located in Beijing, China. "Formosibittacus" was first studied by Yan-Li Li, Dong Ren and ChungKun Shih of the Capital Normal University. Their 2008 type description of the genus and species was published online and then in print in the journal "Zootaxa". The generic name was coined by Li, Ren and Shih from a combination of the Latin "formos" meaning beautiful and the modern Bittacidae genus "Bittacus" to which "Formosibittacus" is related. The etymology of the specific epithet "macularis" is in reference to the numerous maculae which are present on the holotype wings.
