An updated list of butterflies (Lepidoptera, Papilionoidea) of two Guatemalan seasonally dry forests.

Guatemala has a great diversity of butterflies, although there have been few intensive surveys on Lepidoptera in the country so far. We present an updated list of 218 species in 149 genera, 19 subfamilies, and six families of butterflies sampled at two seasonally dry forests in the Salamá and Motagua valleys in central and eastern Guatemala, by integrating new data from field surveys conducted in 2014-2021 into our previously published data (Yoshimoto et al. 2018, 2019), with Godman, 1900, (Godman, 1900), and Hayward, 1948 (Hesperiidae: Hesperiinae) as new country records.
