Fig. 12A–F

Solierella nigridorsum Pulawski, 1964: 136, ♀.

Diagnosis. Body length: 3.6 mm.

This species is characterized by the entirely black thoracic dorsum (Fig. 12A, C).

Material examined: 1♀, Farasan, Abdulmajeed farm [16 Q 42.07970’N; 42 Q 08.5781’E], 23–30.ix.2022.

Distribution: Egypt, Iran, Saudi Arabia (new record), United Arab Emirates.

Comments. This species is a new record for Saudi Arabia. Characters of the only collected specimen agree well with Pulawski’s description of the Egyptian females (1964: 136). It also agrees with the Arabian S. nigridorsum in having the metanotum completely black (Schmid-Egger 2011). Furthermore, it agrees with the Iranian female in having the pronotum and metanotum black (Schmid-Egger et al. 2021).
