Crematogaster ghoneimi, sp. nov., A New Ant Species (Hymenoptera: Formicidae) from the Kingdom of Saudi Arabia

Abstract. Crematogaster ghoneimi, sp. nov. is described from the southwestern mountains of the Kingdom of Saudi Arabia (KSA) based on the worker caste. The new species is most similar to C. chiarinii Emery, 1881, type locality Ethiopia, and can be readily distinguished from all other regional congeners by the long, thin, and acute propodeal spines, presence of a single pair of hairs on the promesonotum, and lacking a subpetiolar process.
