Hoploteleia grandis Dodd, 1913: 176 (original description); Kieffer 1926: 367, 378 (description, keyed).

Oxyscelio grandis (Dodd): Dodd 1931: 75 (generic transfer); Galloway 1976: 99 (type information).

Description.

Female. Unknown.

Male. Mesosoma + metasoma length 3.38 mm (n=1).

Lateral pronotal area sculpture: anteriorly smooth, posterodorsal corner with dense microsculpture, ventral corner with irregular carinae. Posterior border of central pronotal area: directed anteriorly, protruding at corner of epomial carina and transverse pronotal carina. Mesoscutum anteriorly: not steep, forming less than a right angle. Median mesoscutal carina: absent. Mesoscutellar rim: not expanded. Mesoscutellar rim medially: without notch. Mesofemoral depression: longitudinally striate dorsally, smooth ventrally. Metascutellum shape: slightly emarginate posteriorly, concave but elevated posteriorly. Metascutellar setae: absent. Metascutellum sculpture: with large smooth posterior fovea. Coxae color brightness: same color as femora. Lateral propodeal carinae: broadly separated, not parallel anteriorly. Setae in metasomal depression: absent. Anterior sculpture of metasomal depression: absent. Median propodeal carina: absent. 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. Major sculpture of mesoscutellum centrally: umbilicate foveate; absent. Major sculpture of mesoscutellum peripherally: umbilicate foveate. Microscu lpture of mesoscutellum centrally: absent. Microsculpture of mesoscutellum peripherally: absent. Fore wing apex at rest: unknown.

T1 midlobe longitudinal carinae: unknown. T3 metasomal flanges: absent. T4 metasomal flanges: absent. T5 metasomal flanges: absent. T6 metasomal flanges: absent. T7: with a pair of sharply defined spine-like posterolateral projections.

Diagnosis.

Male: Median carina of mesoscutum absent. Mesoscutellum without granulate sculpture. T1 lateral carina not expanded. T7 with narrow and elongate posterior spines.

Comments.

Oxyscelio grandis is known only from a broken male specimen consisting only of a mesosoma and metasoma, which was its state when described by Dodd (1913). These parts are sufficient to establish that no other known Australian specimens belong to this species. The elongate T7 spines are unlike those of any member of the atricoxa-group, suggesting that this species likely belongs to another species group, or that it is not closely related to any other known Australian Oxyscelio . This species is excluded from the phylogenetic analysis due to the very large amount of missing data.
