Abstract
A new species of the eucerine bee genus letraloniella Ashmead (Apinae: Eucerini) is described and figured from central Saudi Arabia and Qatar. Tetraloniella (Tetraloniella) persiciformis sp. n. is distinguished on the basis of coloration, integumental sculpturing, male metafemoral structure, and male terminalia. A floral record of Pulicaria undulata (L.) C.A. Mey. (Compositae) is noted for some of the material. Females superficially resemble those of Tarsalia persica (Warncke) (Ancylaini) in overall coloration but can be distinguished by the typical generic and tribal characters.
