Remarks

• Systematics: Le Pelley (1968) states that "the numerous references to Cerococcus hibisci Green in Africa are doubtless misidentifications of C. coffeae(=C. theydoni)." In having small convex closed pores associated with each of the spiracles, A. theydoni is also very similar to A. gabonensis and A. ornata, but both of the latter two species have a different distribution of 8-shaped pores on the dorsum and, critically, their posterior stigmatic pore bands are not bifurcated, the anterior branches having been lost. In addition, adult female A. ornata lack leg stubs.
• Structure: Female test is fairly convex, subcircular, tan and with wax projections in the form of evenly spaced tufts. Female body is pear shaped with membranous derm (Lambdin & Kosztarab, 1977a Adult females of A. theydoni are characterised by the following combination of character-states: (i) dorsum with three sizes of 8-shaped pores; (ii) large and medium-sized 8-shaped pores in swirls throughout head, thorax and abdomen; (iii) each stigmatic band with 0–3 minute 8-shaped pores in apex; (iv) posterior abdominal segments with a line of 10–14 large 8-shaped pores on each side dorsally; (v) cribriform plates in a submedial group of two on each side of abdominal segment IV, each with large micropores; (vi) leg stubs present; (vii) posterior stigmatic pore bands bifurcated; (viii) small convex closed pores present in a sparse band between anterior spiracles and metathoracic leg stubs; (ix) multilocular disc-pores present across all abdominal segments and laterad to metathoracic leg stubs; (x) multilocular disc-pores also present mesad to each spiracle; and (xi) antennae without either a cone-like apex or a setal cavity. (Hodgson & Williams, 2016)
• Economic Importance: This species has been a pest of coffee in much of eastern Africa (Le Pelley, 1968).
• General Remarks: Detailed description and illustration by Lambdin & Kosztarab (1977a). Hamon & Kosztarab (1979) provide a detailed description and illustration of the first instar. Detailed redescription and illustration in Hodgson & Williams, 2016.
