Nothing is known about the biology of this species.


Salata and Borowiec (2015) - Worker. Oxyopomyrmex polybotesi belongs to the species group that has a distinctly punctate propodeum. It is distinguished from Oxyopomyrmex emeryi and Oxyopomyrmex oculatus by the longitudinal striae covering whole frontal surface of the head and the presence of the rugosity and longitudinal striae on dorsal surface of the pronotum; from Oxyopomyrmex negevensis it differs in the lack of transverse striation on dorsal surface of the pronotum, the shiny abdomen and the more dense and thicker hairiness at the scape and legs. At first glance O. polybotesi is very similar to Oxyopomyrmex pygmalioni but it differs in following features: the shiny gena without rugosity (while O. pygmalioni has the gena dull and distinctly rugose), the occurrence of distinct longitudinal striae on the lateral surfaces of the pronotum (in O. pygmalioni the lateral surfaces of the pronotum are rugose with a slight longitudinal striae) and the dorsal surface of pronotum is shinier, weaker rugulose with longitudinal striae at the posterior edge (in O. pygmalioni the dorsal surface of pronotum is distinctly rugulose to rugose, and striation, if present, is oblique).
