Abstract
Tetramorium sericeiventre Emery,
1877
is a widespread ant of Africa, Arabia, and neighbouring areas. Across its broad range, T. sericeiventre shows much variation and many different forms have been described. In the present study, we report additional site records of T. sericeiventre on the Arabian Peninsula, and provide information on species variation, habitat, behaviour, and distribution. In addition, we evaluate the global distribution of this species and present a taxonomic diagnosis of T. sericeiventre for facilitating species recognition. Tetramorium sericeiventre thrives in a wide variety of open habitats, ranging from intact natural areas to sites heavily disturbed by human activity. Genetic analyses would be useful in elicidating the relationships among the many different forms of T. sericeiventre.
