Salata & Borowiec, 2015
Specimens were collected by sweep net in arid littoral habitat, located on a small peninsula close to the sea. The peninsula was vegetated by pine grove and Mediterranean scrubland.
Salata and Borowiec (2015) - Worker. Oxyopomyrmex laevibus belongs to a group of species characterized by having the head with longitudinal striae on the entire frontal surface. Oxyopomyrmex laevibus is distinguished from workers of Oxyopomyrmex krueperi by the more gentle curved border between dorsal and posterior surfaces of the promesonotum (in the profile view), lacking striation on dorsal surface of the head and gena, and lack of rugae on the center of the dorsal surface of its mesonotum; from Oxyopomyrmex nitidior it is distinguished by lack of smooth and shiny sculpture at the center of its frons and the lack of distinct rugosity and striation on dorsal surface of the pronotum; from Oxyopomyrmex pygmalioni and Oxyopomyrmex polybotesi it is distinguished by lacking punctation and rugosity at the centre of the pronotum and the gena are devoid of rugosity; from Oxyopomyrmex magnus is distinguished by the HI<100 and the lack of the distinct striation and rugosity at the gena, posterior margin of the head and pronotum; from Oxyopomyrmex saulcyi and Oxyopomyrmex nigripes is distinguished by the convex promesonotum, lacking striation and distinct rugosity at the thorax and by the darker body colouration.
