• Systematics: Slide-mounted adult female with: 6 setae in each outer row of small dorsal setae and only 4 in each inner row; quinquelocular pores rare or absent medially on thorax; large group of sessile pores medially between bases of antennae and mouthparts (Hodgson & Henderson, 1996).
• Structure: Adult female moderately convex, often lying laterally, curved around twigs and or nodes of host plants; dark brown, moderately shiny and generally accompanied by much sooty mold. Adult male winged, robust with well- developed legs and antennae and a stout penial sheath (Hodgson & Henderson, 1996).
• General Remarks: Hodgson & Henderson (1996) provide detailed description, illustration, phylogeny and key of adult male and female as well as second instar of both sexes, first instar nymph, pupa and prepupa. Hodgson (2002) used this species in a phylogenetic analysis of non-margarodid Coccoidea. Detailed description and illustration of male in Hodgson (2020)
