Batrachedridae

The Batrachedridae are a small family of tiny moths. These are small, slender moths which rest with their wings wrapped tightly around their bodies.

The taxonomy of this and related groups is often disputed.

This group was first proposed as a taxonomic rank in 1876 by Hermann von Heinemann and Maximilian Ferdinand Wocke under the name Batrachedrae. Lord Walsingham used the name Batrachedridae in 1890.

Ron Hodges decided to separate a number of new species he was describing in 1966 from Batrachedra in his new genus Chedra, on the basis of the adult males possessing a "single, strong, apical spine on the ampulla" (also known as the harpe). Chedra then accommodated three species: two from North America and one from Chile. Hodges furthermore described two more related genera in this paper: Duospina and Ifeda. These genera he all placed in the family Gelechioidea.

In his 1978 treatment of the microlepidoptera of Hawaii, Elwood Zimmerman classified this group as a new subfamily of the family Gelechiidae, which he coined the Momphinae. Zimmerman split five local species from the genus Batrachedra to a new genus Batrachedrodes on the basis of morphology and the particular habit of feeding among sporangia on the underside of fern fronds.

That same year, however, Hodges classified Batrachedra, Chedra, Duospina and Ifeda in the family Batrachedridae in The moths of America north of Mexico. Hodges changed the classification in his 1983 Check List of the Lepidoptera of America North of Mexico and included the group as the subfamily Batrachedrinae of the family Coleophoridae.

Meanwhile, in Italy, the microlepidopterist Giorgio Baldizzone published an account of the Coleophoridae of Australia in 1996, in which he removed the genus Corythangela from that family to the Batrachedridae sensu Hodges 1978, apparently not having read or not following Hodges 1983 yet, upon examining the genitalia of the two species then known from the territory and finding them more similar to those of other Batrachedridae.

In 1999 Hodges reclassified it again as the family Batrachedridae. He also reclassified the family Epimarptidae as the subfamily Epimarptinae of this family, based on a number of shared synapomorphies. The Batrachedrinae sensu stricto he then reclassified as the subfamily Batrachedrinae. At the time Hodges considered the subfamily Batrachedrinae to include more than 100 species in five genera worldwide.
