Notes. Euphaea guerini was originally described by Rambur (1842) based on specimens from southern Vietnam, but the description did not contain any figures of structures. Later, Selys & Hagen (1854) provided a more detailed description of Rambur’s holotype, including a good illustration of the appendages (see Fig. 2 View FIGURE 2 , pl. 14 in Selys & Hagen 1854). The shape of S10 ( Fig. 20f View FIGURE 20 ) and the small size of the Vietnamese specimens is in line with this description and supports the identification of the material presented in this study as Euphaea guerini and not E. saola sp. nov..

Male of Euphaea guerini has black body and extensively darkened wings. FW are hyaline both basally and apically. HW are very dark with metallic blue on the underside covering about two-thirds of the wing, and with green flash on basal anal area on the upperside ( Fig. 14c View FIGURE 14 ). Male S9 bears a bundle of hairs ( Fig. 15b View FIGURE15 ). In female, wings are hyaline with orange-yellowish area basally, and head, thorax and abdomen marked yellowish as in Figure 16e View FIGURE 16 . This species has not been recorded in Thailand ( Hämäläinen 2017) and Cambodia ( Kosterin 2014, 2016), although Martin (1904) and then Asahina (1985) mentioned Cambodia as a locality of this species without giving a specific location. Yokoi & Kano (2002) and Yokoi & Souphanthong (2005) reported it from central and southern Laos. However, in Cambodia, central to southern Laos, and central Vietnam, the past records of Euphaea guerini may include E. saola sp. nov.

Distribution. Vietnam (Thai Nguyen, Phu Tho, Vinh Phuc, Hoa Binh, Nghe An, Ha Tinh, Quang Binh, Quang Tri, Thua Thien-Hue, Quang Nam, Quang Ngai, Lam Dong and Khanh Hoa Provinces), China (Guangxi Province) ( Wilson & Reels 2003), Laos (Bolikhamxay and Attapeu Provinces) ( Yokoi & Kano 2002, Yokoi & Souphanthong 2005).
