Salata and Borowiec (2015) - Forel (1911) and Menozzi (1936) reported finding nests in sandy soil at a barren hill near Thessaloniki and on a path to Pigadia beach at Karpathos. Specimens were also collected in an agricultural field in Iran (Ghahari et al. 2011). Authors found a nest under a stone on the western slope of Psiloritis on Crete, at elevation 578 m a.s.l (above Fourfouras village). The area there is overgrown by a typical Mediterranean shrubland and olive trees.

Identification

Salata and Borowiec (2015) - Worker. Oxyopomyrmex krueperi is clearly distinguished from all other species by a sharply curved border between dorsal and posterior surfaces of the promesonotum (in the profile view). There are only two species, in which the border between dorsal and posterior surfaces of the promesonotum can have such shape: O. emeryi and Oxyopomyrmex nitidior. Oxyopomyrmex krueperi can be easily distinguished from O. emeryi by the thin, longitudinal striae covering the entire frontal surface of its head, the rectangular shape of the head and lacking punctation on the dorsal surface of the pronotum. Oxyopomymex krueperi differs from O. nitidior in the lack of shiny surface on the center of the frons, the gentler and thinner striation on the dorsal and lateral surfaces of the promesonotum and in the black colouration of the body. Among studied material, two workers of O. krueperi had the border between dorsal and posterior surfaces of the promesonotum curved under less acute angle. At first glance, they resemble workers of Oxyopomyrmex laevibus, but O. krueperi differs by having the presence of longitudinal striae at the gena and posterior margin of the head and by having the rugosity covering dorsal surface of the pronotum. Oxyopomyrmex krueperi is distinguished from O. nitidior by lack of smooth and shiny sculpture at the center of the frons and the darker colouration; from Oxyopomyrmex pygmalioni and Oxyopomyrmex polybotesi is distinguished by lacking punctation at the centre of the pronotum and its gena are devoid rugosity; from O. magnus it differs in lacking rugosity at the gena and the SI<100; from O. saulcyi and O. nigripes is distinguished by the convex promesonotum, the weaker striation and rugosity covering the dorsal surface of its promesonotum, the darker colouration and its gena are more shining with weaker and sparser longitudinal striae, never rugulose.

Gyne. Oxyopomyrmex krueperi is distinguished from Oxyopomyrmex magnus by the HI < 100; from Oxyopomyrmex oculatus and Oxyopomyrmex nigripes it differs in lacking rugosity between striation at the gena. It is very hard to distinguish O. krueperi from Oxyopomyrmex saulcyi. Oxyopomyrmex krueperi has a triangular, broadly attached propodeal spines which rising obliquely upwards but the peaks of the spines are posteriorly oriented whereas most of the studied gyne of O. saulcyi has propodeal spines triangular, short, broadly attached, directed obliquely upwards with sharp or blunt peaks. Only one gyne of O. saulcyi had peaks of the propodeal spines directed slightly downward. In distinguishing these two species the differences in the colouration and the geographical separation can be also used (Oxyopomyrmex krueperi has body black with reddish fragments and it occurs in the Eastern part of the Mediterranean region whereas O. saulcyi has body brown to dark brown with paler fragments and inhabits the Western part of the Mediterranean region).

Male. Oxyopomyrmex krueperi is distinguished from O. oculatus by the occurrence of the longitudinal striae on dorsal surface of the scutum and lacking punctation on it; from Oxyopomyrmex insularis it differs in the occurrence of the longitudinal striae at its frons and by having the vertical striation on dorsal surface of the head; from O. nigripes and Oxyopomyrmex emeryi it differs in the occurrence of the rugosity between longitudinal striation at the scutellum; from O. magnus and O. emeryi it can be distinguished by the presence of the lobe-like propodeal spines and from O. saulcyi it differs in the occurrence of smooth, shiny and devoid of the longitudinal striae surface on the dorsal surface of the postpetiole and by the black colouration of the body.
