A new species of Habrophorula from Vietnam and an updated key to species of the genus (Hymenoptera, Apidae).

The rare bee genus Habrophorula Lieftinck, 1974 is recorded for the first time from Vietnam. The genus is represented by a new species, Habrophorulabelladeceptrix Tran, Engel & Nguyen, sp. nov. , from Cao Bang Province and can be most easily confused with H.nigripes Wu from China. The species is most easily differentiated by the unique form of the male terminalia but can also be distinguished by differences in integumental and setal coloration. A revised key is provided to the species of the genus. Females of the new species were collected at flowers of Saurauiaroxburghii Wall. and Saurauianapaulensis DC. (Actinidiaceae); males were collected at flowers of Lantanacamara L. (Verbenaceae).
