Oxyscelio scutorum sp. n., holotype female (OSUC 359721) 313 Head and mesosoma, lateral view 314 Head and mesosoma, dorsal view 315 Head, anterior view 316 Metasoma, dorsal view. Paratype male (OSUC 359730) 317 Antenna 318 Metasoma, dorsal view. Morphbank87 Diagnosis. Both sexes: Mesoscutum and mesoscutellum black. Frontal depression shallow, transverse carinae absent; submedian carina indicated by a set of irregular elevations or weak carinae. Hyperoccipital carina indicated by sharp carina. Occipital carina with a faintly indicated convex medial portion. Metascutellum concave, broad and short, projecting dorsally. Coxa not darker than rest of leg. T1 lateral carina expanded laterally. Metasomal flanges absent. Female: A3 shorter than pedicel. A4, A5 much broader than long. Mesoscutellum with obliquely raised sculpture. T1 midlobe with 4 longitudinal carinae. T6 without metasomal flanges. Fore wing long enough to reach or exceed metasomal apex. Male: A4 broader than long, A11 longer than broad. T1 midlobe with 4 longitudinal carinae. Fore wing long enough to exceed metasomal apex. T7 much broader than long, blunt apically, without posterior projections. Oxyscelio scutorum is very similar to Oxyscelio brevitas in having a roughly sculptured occiput and strong hyperoccipital carina. It differs having a stronger hyperoccipital carina and an indicated submedian carina. The raised oblique mesoscutellar sculpture is also distinctive, but it may be difficult to distinguish in some specimens. It sometimes accompanies a flat, broad median mesoscutellar carina. Etymology. Latin noun, genitive case, meaning "shields." Link to distribution map. [http://hol.osu.edu/map-full.html?id=307107] Material examined.
