From Salata & Borowiec 2015 [1]

Diagnosis of gyne. Head quadrate to rectangular, longer than wide (except for O. magnus). Frontal carinae short, never exceeding 1/3 length of the eye. Mandible striate, with 7–8 teeth, the apical tooth massive and long. Antennae 11 segmented; antennal club 3-jointed. Compound eyes large, elongate, narrowing downward, reaching anteroventral margin of head. Gena with either striae and rugae sparser than on frons or smooth, without sculpture, often shinier. Entire head bearing setae, posterior margin with sparse to dense erect setae directed forward, lateralsurfaces of the head with sparse to dense semierect setae always directed toward anterior margin, frontal area with sparse to dense, appressed to erect setae, placed transversely and directed to the center of the head, ventral surface of the head with a prominent psammophore and appressed to erect long setae. Promesonotum projecting dorsally above propodeum, flat or slightly convex in profile. Scutum and scutellum always sculptured, sometimes smooth at center. Propodeal spines always with wide base, usually triangular, rising obliquely upwards. Abdomen shiny with long semierect to erect setae.

Diagnosis of male. Head oval, longer than wide. Frontal carinae short, curved outward to merge with the rugae surrounding antennal sockets. Mandible striate, with 4-5 teeth, the apical tooth massive and long. Antennae 12 segmented. Compound eyes large, oval. Gena with either striae and rugae sparser than on frons or smooth, without sculpture, often shinier. Entire head bearing setae, posterior margin with sparse to dense erect setae directed forward, lateral surfaces of the head with a few appressed to dense, semierect setae directed toward anterior margin, frontal area with sparse to dense, appressed to erect setae, placed transversely and directed to the center of the head. Ventral surface of the head with a long psammophore and appressed to erect long setae. Promesonotum projecting dorsally above propodeum, flat or slightly convex in profile. Scutum and scutellum always sculptured with three smooth longitudinal stripes at the scutum. Central stripe always shorter. Propodeal spines with wide base, short or absent. Abdomen shiny with long semierect to erect setae. No significant differences in genitalia shape and structure were observed.

Diagnosis of worker. Worker small to medium sized, monomorphic. Head elongate to quadrate, longer than wide (except for O. magnus, O. emeryi, O. nitidior). Frontal carinae short, never exceeding 1/3 length of the eye. Mandible striate, with 7-8 teeth, sometimes apical tooth massive and long. Antennae 11 segmented; antennal club 3-jointed. Compound eyes large, elongate, narrowing downward, reaching anteroventral margin of head. Gena with either striae and rugae sparser than on frons or smooth, without sculpture, often shinier. Entire head bearing setae, posterior margin with sparse to dense erect setae directed forward, lateral surfaces of the head with a few appressed to dense semierect setae always directed toward anterior margin, frontal area with sparse to dense, appressed to erect setae, placed transversely and directed to the center of the head, ventral surface of the head with a long psammophore appressed to erect long setae. Promesonotum projecting slightly higher than propodeum, flat or sometimes convex in profile. Pronotum and mesonotum always sculptured, sometimes with smooth surfaces at
the center of the mesonotum. Propodeal spines always with wide base, usually triangular rising obliquely upwards. Abdomen shiny with long semierect to erect setae (except for O. negevensis).
