Metasoma. Shape of metasoma oval in dorsal view; ratio of width of metasoma to its length 0.5 0.6; carapace broadens to posterior end in lateral view; ratio keel to metasoma length 0.2 0.3; carapace fine rugose. Colour. Head and metasoma black; antenna brown; legs and carapace red brown; wing venation, parastigma and pterostigma dark brown. Diagnosis The colour of the carapace distinguishes this species from all those currently described species in Australia . In addition, A. ferruginegaster is one of only five species, along with A. prolixogaster , A. rubriscapa and two undescribed species ( Ascogaster sp. 25 and Ascogaster sp. 28), that has a 3-bp indel in its CO1 sequence at position 271 273.
