Diagnosis The colour of the carapace distinguishes this species from all those currently described species in Australia. In addition, A. ferruginegasteris one of only five species, along with A. prolixogaster, A. rubriscapaand two undescribed species ( Ascogastersp. 25 and Ascogastersp. 28), that has a 3-bp indel in its CO1sequence at position 271 –273.
