Idioglossa

Idioglossa is a genus of moths of the family Batrachedridae.

Taxonomy
The genus was created by Thomas de Grey, 6th Baron Walsingham in 1881 to house the new species Idioglossa bigemma. Because Lord Walsingham had created a monotypic genus at the time, the species I. bigemma is considered the type species by monotypy. The next year, in 1882, Lord Walsingham proposed to rename the taxon as Idiostoma, because he considered the name inappropriate, but by the rules of taxonomy this is considered unnecessary.

The Australian entomologist Ian Francis Bell Common classified it in the subfamily Stathmopodinae of the family Oecophoridae in 1996. It was reclassified in the subfamily Batrachedrinae of the Batrachedridae by Kazuhiro Sugisima in 2000.
