New Nepticulidae species (Insecta: Lepidoptera) from the Yucatán Peninsula (SE Mexico)

Thirty-eight species of Nepticulidae are known from the Yucatán Peninsula and adjacent areas (mainland Mexico and Belize). This paper describes two new species: Stigmella maya Remeikis & Stonis, sp. nov. (a leaf-miner of Karwinskia humboldtiana, Rhamnaceae), and Acalyptris yucatani Remeikis & Stonis, sp. nov. (a leaf-miner of Schinus sp., Anacardiaceae). S. maya is among the smallest Lepidoptera in the world. In its male genitalia S. maya resembles a sizeable group of undescribed species occurring in the Andes (Patagonia: Argentina). The adults of both new species are illustrated with photographs of adults, genitalia and leaf-mines.
