Abstract

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.

摘要

新种蓝须色蟌（Euphaea cyanopogon sp. nov.）是根据在柬埔寨南部的贡布半岛以及越南相邻的富国岛采集的雌雄标本描述和图示的，这两个地方都位于豆蔻生态区；正模♂（保存在莱顿的荷兰国家自然历史博物馆）采自柬埔寨的Kbal Chhay瀑布。雄性的特征是翅膀相当狭窄，没有强烈色素沉着的区域，面部有亮蓝色斑纹。讨论了新物种与1985年描述的帕氏色蟌（E. pahyapi Hämäläinen）及其一些同属物种的差异和亲缘关系。
