First records of the genus Elatosara Malzacher, 2020 (Ephemeroptera, Caenidae) from the Lao People’s Democratic Republic

Abstract

The genus Elatosara was described by Malzacher, 2020 from the Mekong River in Thailand, with E. phanomensis Malzacher, 2020 as its type species. Here, we report E. phanomensis for the first time from central and southern Lao People’s Democratic Republic (Lao PDR). A few morphological variations were observed in the Lao PDR population as compared to the paratypes of E. phanomensis. The discovery of E. phanomensis extends the distribution of the genus to the Lao PDR.
