Nothing is known about the biology of Oxyopomyrmex negevensis.
Identification
Salata and Borowiec (2015) - Worker. Oxyopomyrmex negevensis is the only species known to have the first abdominal tergite bearing a dense layer of appressed microsetae. It belongs to the species group that has punctae on the dorsal surface of the pronotum. From Oxyopomyrmex oculatus it can be distinguished by the presence of vertical striae on the dorsal surface of the pronotum and longitudinal striae covering the entire frontal surface of the head; from Oxyopomyrmex polybotesi and Oxyopomyrmex pygmalioni it is distinguished by the presence of vertical striae and lack of rugosity on the dorsal surface of the pronotum; from Oxyopomyrmex emeryi it differs in the occurrence of longitudinal striae on the entire surface of the head and the rugae on the gena.
