Notes. This species is newly recorded for Vietnam, although Bui (2007) published the same taxon first as Euphaea ochracea . Hämäläinen (1985) described Euphaea pahyapi from the peninsular part of Thailand based on male specimens. Asahina (1985) also described Euphaea khaochongensis from another province of the same area, but this was treated as a junior synonym of E. pahyapi by Pinratana et al. (1988) and in Hämäläinen & Pinratana (1999). Euphaea pahyapi can be distinguished from all Vietnamese Euphaea species by the unique completely and evenly amber-colored wings of the male ( Fig. 18d View FIGURE 18 ). Color pattern of the head is variable, entirely black as in the original description ( Hämäläinen 1985) or with dirty blue markings as in Asahina's (1985) description and our specimens from Vietnam (Phu Quoc Island) ( Fig. 19b View FIGURE 19 ). Abdomen and anal appendages are as in Euphaea masoni , with hairs only on S3 ( Fig. 15d View FIGURE15 ). Vesicle of Euphaea pahyapi differs from that of E. masoni by being heart-shaped, pointed at its posterior margin ( Fig. 18f View FIGURE 18 ) whereas it is ax-shaped with the posterior margin rounded in E. masoni ( Fig. 18e View FIGURE 18 ). Female of this species is still undescribed.

The record of Euphaea ochracea from Kbal Chhay Cascades of Preah Sihanouk Province, Cambodia in Kosterin et al. (2012) is a misidentification and concerns in fact E. pahyapi ( Kosterin 2016, and pers. comm.)

Distribution. Vietnam (Phu Quoc Island), Thailand (Ranong, Krabi, and Trang Provinces) ( Hämäläinen 2017), Cambodia (Preah Sihanouk Province) ( Kosterin et al. 2012, and Kosterin pers. comm.).
