Type Material
Monomorium yemene: Holotype: worker, Yemen, Taiz, 20.X.1991, A. van Harten. - Paratypes: Yemen: workers, same series as holotype; workers, Zingibar-Shugra, 21.111.1993, C. A. Collingwood.

Sharaf et al. (2021): The locality label of the paratype specimen (CASENT0913865) (Madinat Al shiraq) is not matching the locality data mentioned in the original description but the collecting data and collector are congruous with the description, therefore, this specimen is treated as one of the type material of M. yemene.

Description
Collingwood and Agosti (1996) - HL 0.75-0.90; HW 0.67-0.91; SL 0.61-0.76; CI 89; SI 90.

The clypeus is widely emarginate. The propodeal furrow is exceptionally well defined with raised side margins. The alitrunk profile is flat with the mesopropodeal furrow distinct but shallow. There are no alitrunk hairs, one pair on the petiole, 1-2 pairs on the postpetiole and occasional hairs on the first gastral tergite. The head and alitrunk have dense reticulopunctate sculpture. The gaster is shining with superficial sculpture, black in whole or in part but well contrasted with the red head, alitrunk and nodes.
