Stonis, Jonas R., Diškus, Arūnas, Remeikis, Andrius, Karsholt, Ole & Torres, Nixon Cumbicus, 2017, Illustrated review of the leaf-mining Nepticulidae of the central Andes (Peru and Bolivia), Zootaxa 4257 (1), pp. 1-70 : 58

The Acalytris peteni group (designated here) (species 44)

Diagnostics: externally the species are quite similar and resembling to the most of other Neotropical Acalytris (not belonging to the A. peteni group); some with adroconia on hingwing upper side or underside. In male genitalia, phallus with a specific set of thickenings and carinae. In the female genitalia, corpus bursae, in contrast to the European Acalyptris , with signa reticulata comprised of slender inner part and wide outer part. Currently, beside unaffiliated species, the group additionally includes two species complexes (designated and diagnosed in Stonis & Remeikis 2015), and in total comprises more than 20 species from the Caribbean (including southern Florida , USA) and Central and South America, with the highest species diversity recorded in Belize . The species are trophically associated with at least four plant families: Verbenaceae , Fabaceae , Anacardiaceae , and Meliaceae ; the latter host-plant record belongs to an undescribed species from Ecuador (Stonis et al. in prep.). Leaf-mines resemble slender galleries throughout the course, widened either very little or not at all in distal half.
