The species of Barbenigma do not fit in any of the currently known subfamilies of Ortheziidae. Barbenigma species are similar to the Australian ortheziid ant inquiline Acropygorthezia williamsi in having: eyes absent; a reduced or absent ovisac band; no wax plates; a reduced number of antennal segments; and two campaniform sensilla on each surface of the trochanter. However, Barbenigma species have (A. williamsi character states in parentheses): three-segmented antennae (two-segmented); atria of thoracic and abdominal spiracles each with ring of pores (spiracular atria without pores); ventral clusters of quadrilocular pores and spines on abdomen (ventral quadrilocular pores present singly); few dorsal spines scattered over body (densely covered in spines); ventral spines absent except marginally and in pore clusters (entire venter densely covered in spines); and anal ring well developed with pores, situated at apex of abdomen (anal ring without pores, situated at center of body). (Powell et al. 2024)

Legs reduced in size, tibia and tarsus not fused, trochanter with two campaniform sensilla on each surface, trochanter and femur fused. Ovisac band modified. Wax plates, multilocular pores, and eyes absent. With three pairs of abdominal spiracles, atria of both thoracic and abdominal spiracles each with ring of raised pores. Abdomen with eight quadrilocular duct and spine clusters. Setae on dorsum and margin robust and fimbriate, spines on dorsum and margin each with swollen rounded apices, setae and spines reduced in number. (Powell et al. 2024)
