( Figures 7a –e, 15) Description (female) Body measurements.Length of body 4.4 mm; ratio of antenna to body 0.5; ratio of length of fore wing to body 0.7; ratio of length of metasoma to mesosoma 1.4. Head.Antenna with 19 antennomeres; ratio of length of third antennomere to fourth 1.2; ratio of length of third, fourth, penultimate and terminal antennomere 5.8, 4.8, 1.7 and 2.3 times their width, respectively; ratio of length of eye in dorsal view to length of temple 5.8; ocelli isosceles; imaginary line between anterior margins of posterior ocelli is not touching the anterior ocellus; ratio of width of face in anterior view to its height 2.4; ratio of width of clypeus to its height 2.0; clypeus without teeth; ratio of length malar space to base of mandible 2.8; face punctate; frons rugose; eyes glabrous; ratio posterior ocelli:LOL:POL:OOL 1.0:3.0:1.5:3.0. Mesosoma.Middle lobe of mesoscutum punctate; notauli present; mesoscutellum shiny, fine punctate, weakly convex; mesopleuron shiny, punctate; precoxal sulcus present; ratio of height of mesosoma to its length 1.5; hind coxa shiny, fine punctate; ratio of length of hind tibia to hind tarsus 1.0; ratio hind coxa, hind femur, hind tibia and hind tarsus 1.7, 5.6, 4.7 and 11.0 times their width, respectively; ratio of length of posterior spur to length of basal tarsus 0.5; fore wing: 2-R1 absent; ratio of length of 1-R1 to length of pterostigma 1.0; ratio of width of pterostigma to its length 2.8; ratio r:3-SR:SR-1:r-m 1.0:0.7:4.2:0.8; SR-1 completely sclerotised; 1-SR+M emanating from 1+M; 2-SR+M antefurcal. Metasoma.Shape of metasoma long oval in dorsal view; ratio of width of metasoma to its length 0.48; carapace broadens strongly to posterior end in lateral view; ratio keel to metasoma length 0.11; carapace rugose. Colour.Black; except legs, pedicel, tegula and wing venation brown.
Diagnosis Superficially similar to A. prolixogaster, but A. rubriscapalacks the elongated tip of the carapace. Overall, it can be distinguished from all other Australian Ascogasterspecies by the combination of its colour and size, the shape of the carapace and the number of antennomeres. In addition, A. rubriscapais one of only five species, along with A. ferruginegaster, A. prolixogasterand two undescribed species ( Ascogastersp. 25 and Ascogastersp. 28), that has a 3-bp indel in its CO1sequence at position 271 –273.

Taylor, MT amongst Senna artemisioides, Acacia tetragonophila, Acacia aneura, and Acacia victoriae; Bush Blitz survey 367 Malaise 9 ”( SAM). Male.Unknown.
Biology Unknown.
Etymology The name refers to the red scape of the specimen.
