Notes. This species is distributed in northern and central Vietnam. Male wings are pale orange colored, but the apices are hyaline. Bodies of male and female are shown in Figure 17a and 17b , respectively. Asahina (1977) noted that male specimens taken in Malaysia and southern Thailand have an entirely pale brownish [sic] HW, but that in Laotian males, the brownish [sic] area of HW is restricted before the pterostigma, although a clear geographical differentiation using this character seems difficult. We also confirmed this difference between Malaysia and Laos. In Vietnam and China, all male specimens examined have a HW similar to that observed in Laotian males ( Fig. 17a ). Male genital ligula has laterally curved flagella typically seen in other Euphaea species, but these are relatively narrow and elongated ( Fig. 17c ).
