Appressed white pilosity on lateral sides of tergum 1 almost reaching base of horizontal part of tergum 1 (Fig. 23). Carina separating anterior concavity of tergum 1 from its horizontal part with row of strong white hairs (Fig. 23). Disc of tergum 5 densely covered with appressed white pilosity. Head less than 0.9x as long as wide. Body length 4–5mm. Arabian Peninsula..................................................................................... Hoplitis emiratensis
- Second segment of labial palpus 1.75– 2 x as long as first segment. Brightened parts of mandible reddish-brown or mandible entirely black.
