Historical collections continue to support faunistic research: the first record of Saptha divitiosa (Lepidoptera, Choreutidae) from the Nicobar Islands, India

Based on a specimen collected in the mid-19 th century, the first documented record of Saptha divitiosa from the Nicobar Islands is given. This record extends and reshapes the known western limit of this species’ distribution range. Image of the specimen, as well as brief considerations on the known distribution of this species are provided. The specimen also holds a certain historical value, being collected during the first “Galathea” expedition (1845–1847).
