Abstract
The Arabian Temnothorax Mayr, 1861 fauna is revised for the first time. Three species are recognized from the region: Temnothorax arabicus Sharaf & Akbar sp. nov., T. liviae (Agosti & Collingwood, 2011) comb. nov. and T. megalops (Hamann & Klemm, 1967). Leptothorax saudiae Collingwood & Agosti, 1996 was placed in Temnothorax by Bolton (2003), but actually belongs to Tetramorium Mayr, 1855 and is herewithin recombined to Tetramorium saudiae (Collingwood & Agosti, 1996) comb. nov. Automontage images and comparative diagnoses of workers as well as notes on habitats and distribution of treated species are provided. A revised key to the Arabian species based on the worker caste is also presented.
Highlights
The ant genus Temnothorax Mayr, 1861 is widespread and currently represented by 431 valid species and subspecies (Bolton 2017)
The genus Temnothorax awaits a global taxonomic revision; some of the noteworthy contributions to the genus include those of Radchenko (2004, 2005, eastern Palaearctic species key), Seifert (2007, North and Central Europe), Schulz et al (2007, Italy), Terayama (2009, Taiwan), Zhou et al (2010, China), Plateaux & Cagniant (2012, synonymy list of the genus), Czechowski et al (2012, Poland), Bharti et al (2012, India), Reyes-López & Carpintero-Ortega (2013, Iberian peninsula), Snelling et al (2014, California), Prebus (2015, Afrotropical regions), Salata & Borowiec (2015, eastern Mediterranean), Seifert & Csősz (2015, Eurocaucasian region) and Csősz et al (2015, PontoMediterranean region)
Etymology The new species Temnothorax arabicus sp. nov. is named after the Arabian Peninsula
