During our careful examination of specimens in herbaria and during a field survey for the revision of the Papilionoideae for the Flora of Thailand project, we discovered two new records for Thailand, Uraria balansae Schindl. from Narathiwat province and U. barbaticaulis Iokawa, T.Nemoto, J.Murata & H.Ohashi from Tak. Moreover, a species of Uraria recently described for Thailand, U. pseudoacuminata W.Tokaew & Chantar. (Tokaew& Chantaranothai, 2013), was also found in Khánh Hòa, Vietnam; this extension of the distribution of the species is reported here.

A new species of the genus Uraria, U. pseudoacuminata, is described from Thailand. It differs from U. acuminata in having shorter racemes, hooked hairs on the lower part of its pedicels, and glabrous ovaries with only 2, rather than 4(5) ovules. It also tends to be shorter and have shorter leaves and leaflets. A detailed description and illustrations are provided.
