Geographic range
Brachyponera sennaarensis is one of the more successful invasive Ponerine ants (Wetterer 2013), being broadly distributed throughout Sub-Saharan Africa, Iran (Akbarzadeh et al. 2006; Paknia 2006; Tourenq and Shuriqi 2010), and several countries of the Arabian Peninsula including KSA (Collingwood 1985), UAE, Yemen, Oman (Collingwood and Agosti 1996; Collingwood et al. 2011) and Qatar (Sharaf and Aldawood unpublished data).
Ecological and biological notes
Brachyponera sennaarensis has invaded a wide range of habitats on Socotra, especially soil that is moist covered with the leaf litter of date palm trees. This species also commonly nests under rocks and objects associated with moist soils. Brachyponera sennaarensis has also invaded the relatively undisturbed valleys of the island where streams and denser vegetation are found. A nest was found under a stone under a dragon blood tree.
