Figures 173-176; Morphbank61 Description. Female. unknown. Male. Body length 4.1-4.15 mm (n=3). Radicle color and shade: darker than scape. Pedicel color: same as scape. A3: longer than pedicel. A5 tyloid shape: narrow, linear. A6: broader than long. A11: longer than broad. Ventral clypeal margin: with slightly convex median lobe. Interantennal process: not elongate. Lower frons at dorsal margin of interantennal process: without transverse carina. Transverse curved rugae extending from frontal depression to eye: absent. Median longitudinal carina in frontal depression: absent. Ventral portion of frontal depression: with medially interrupted transverse carinae. Dorsal portion of frontal depression: without transverse carinae. Submedian carina: present. Frontal depression dorsally: not hood-like, open dorsally. Upper frons major sculpture: umbilicate foveate; transversely rugose. Upper frons microsculpture: granulate. Hyperoccipital carina: indicated by a set of irregular elevations. Carina connecting occipital carina to hyperoccipital carina: absent. Occipital carina: broadly angular, with rounded median peak. Occiput sculpture: irregularly sculptured. Extra carina ventral to occipital carina: absent. Gena length: shorter than eye. Major sculpture of gena anteroventrally: umbilicate foveate. Major sculpture of gena posteroventrally: umbilicate foveate; rugose. Microsculpture of gena anteroventrally: absent. Microsculpture of gena posteroventrally: granulate. Lateral pronotal area sculpture: anteriorly smooth, posterodorsal corner with dense microsculpture, ventral corner with irregular carinae. Posterior border of central pronotal area: directed posteriorly, epomial carina absent or meeting transverse pronotal carina at arch on lateral surface of pronotum. Mesoscutum anteriorly: not steep, forming less than a right angle. Major sculpture of mesoscutal midlobe anteriorly: umbilicate foveate. Major sculpture of mesoscutal midlobe posteriorly: umbilicate foveate. Microsculpture of mesoscutal midlobe anteriorly: granulate. Microsculpture of mesoscutal midlobe posteriorly: absent. Median mesoscutal carina: present as a ruga. Major sculpture of mesoscutellum centrally: umbilicate foveate. Major sculpture of mesoscutellum peripherally: umbilicate foveate. Microsculpture of mesoscutellum centrally: absent. Microsculpture of mesoscutellum peripherally: absent. Mesoscutellar rim: not expanded. Mesoscutellar rim medially: without notch. Mesofemoral depression: longitudinally striate dorsally, smooth ventrally. Metascutellum shape: not emarginate, concave but elevated posteriorly. Metascutellar setae: absent. Metascutellum sculpture: with many longitudinal rugae. Postmarginal vein: present. Fore wing apex at rest: reaching middle of T6. Coxae color brightness: same color as femora. Spines along tibiae: absent. Lateral propodeal carinae: broadly separated, not parallel anteriorly. Setae in metasomal depression: absent. Anterior sculpture of metasomal depression: absent. Median propodeal carina: absent. T 1 midlobe longitudinal carinae: 3. T3 metasomal flanges: absent. T4 metasomal flanges: absent. T5 metasomal flanges: absent. T6 metasomal flanges: absent. T7: broadly emarginate, with sharply pointed posterolateral lobes. Figures 173-176. Oxyscelio lintris sp. n., holotype male (OSUC 453949) 173 Head and mesosoma, lateral view 174 Head and mesosoma, dorsal view 175 Metasoma, dorsal view. Paratype male (OSUC 453950) 176 Head, anterior view Morphbank61 Diagnosis. Male: A4, A11 longer than broad. Frontal depression moderately deep and mostly smooth, with interrupted transverse carinae ventrally and no carinae above dorsal separator; submedian carina sharp. Hyperoccipital carina represented by a set of rugae. Metascutellum subrectangular, with strong rugae. T1 midlobe with 3 complete longitudinal carinae. Fore wing long enough to reach middle of T6. T7 emarginate with tiny sharp posterolateral apices. Etymology. Latin noun, genitive case, meaning "trough." Link to distribution map. [http://hol.osu.edu/map-full.html?id=307088] Material examined. Holotype, male: AUSTRALIA: NSW, Lord Howe Island, no date, A. M. Lea, OSUC 453949 (deposited in AMSA). Paratypes: AUSTRALIA: 2 males, OSUC 453950 (ANIC); OSUC 453951 (WINC). Comments. Oxyscelio lintris is an unusual species with a rugose metascutellum and short posterolateral corners on T7. This species is therefore of uncertain placement, but is provisionally placed in the aciculae-group because of its similarity to Oxyscelio productionis .
