Here, the new species Anthidiellum (R.) phuchongensis sp. nov. is described along with a description of its nest collected from Phu Chong Na Yoy National Park, Ubon Ratchathani Province, Thailand. In addition, the bee cleptoparasite, Stelis (Malanthidium) flavofuscinular sp. nov., and the male of A. (R.) ignotum Engel, 2009, are described for the first time.
