A New Species of the Genus Palarus (Hymenoptera: Crabronidae)
Wojciech J. Pulawski and Sarah K. Gess
A new species, Palarus inexspectatus, is described from Dubai. It is closely similar to Palarus jaxartes Pulawski and Prentice, from which it differs by details of the elevation of the sternum II and color, the male also by the flagellomeres II-IX distinctly angulate near the midlength, the presence of a midtibial spur, and the shape of tergum VII. Three females and two males were collected on the flowers of Heliotropium kotschyi Gürke (Boraginaceae), and one male on those of Calligonum comosum L’Herit (Polygonaceae). One prey, a male Bembix hauseri Schmid-Egger, was taken from a nesting female. The nest, a sloping burrow, had been excavated.
