Taxonomic history

Before the initial description of the tribe as the family Micronoctuidae in 2005, about 20 species were described in the families

Arctiidae The Arctiinae (formerly called the family Arctiidae) are a large and diverse subfamily of moths with around 11,000 species found all over the world, including 6,000 neotropical species.Scoble, MJ. (1995). ''The Lepidoptera: Form, Function and D ...

instead, while microlepidopterists collect them but usually classify them with unknown miscellaneous microlepidoptera. An extensive, four-part revision of the Micronoctuidae was published by Michael Fibiger from 2007 to 2011 (see References section), describing dozens of species for their first time and classifying them into subfamilies and tribes. A subsequent series of studies of the higher-level classification of the superfamily

showed that the phylogenetic placement of Micronoctuidae is as a clade within the subfamily

of the family

. This reclassification moved Micronoctuidae to the tribe Micronoctuini, its subfamilies to subtribes, and presumably its original tribes to infratribes.
