Euphaea cyanopogon 
Hämäläinen, Kosterin & Kompier, 2019

Euphaea cyanopogon sp. nov. is described and illustrated from specimens of both sexes collected in the Kampongsaom Peninsula in southern Cambodia and the adjacent Phú Quốc Island in Vietnam, both in the Cardamom ecoregion; the holotype ♂ (at RMNH, Leiden) is from Kbal Chhay Waterfall, Cambodia. The male is characterized by having rather narrow wings without areas of strong pigmentation and a face marked with bright blue. The differences and affinities of the new species with E. pahyapi Hämäläinen, 1985 and some of its other congeners are discussed.

Euphaea ochracea, nec (Selys, 1859)
Euphaea pahyapi, nec (Hämäläinen, 1985)

Etymology. The specific epithet, a noun in apposition, is a composite of Latinised forms of two Greek words κυάνεοs: dark blue and πώγων: beard, together meaning ‘blue beard’, referring to the coloration of the lower face in males of the new species.
