Three species of the genus are reported: E. aequicarinata Pasteels is recorded in the central highlands Vietnam (Kon Tum Province) beside the previous record of this species in the northwest (Hoa Binh Province); E. polynesia Vachal is widely recorded throughout Vietnam; the taxonomy of Vietnamese Euaspis basalis (Ritsema, 1874) is a misidentification, and it is indeed Euaspis diversicarinata Pasteels, 1980 and is a new record from Vietnam. A key to the females of Vietnamese species of Euaspis Gerstäcker and a redescription of the female of E. diversicarinata are given with illustrations.

Currently, however, diversity and their conservation status of bees from Vietnam are poorly studied (Le Xuan Hue, 2010; Khuat Dang Long et al., 2004; Khuat Dang Long et al., 2012), and megachiline bees are no an exception. Genus Euaspis Gerstäcker, 1858 comprises 12 described species worldwide. Of them, two species are distributed in Africa and ten species are found in Asia (Ascher & Pickering, 2016; Michener, 2007). This genus is widespread .
