Remarks

• Systematics: In having multilocular disc-pores mesad to each spiracle and small convex closed pores associated with each spiracle, adult females of A. ornatus are somewhat similar to those of A. gabonensis and A. theydoni but the latter two species both possess leg stubs and far more large 8-shaped pores on the dorsum. The small convex closed pores were not found by Lambdin & Kosztarab (1977) but were clearly visible on all the material studied. In addition, Lambdin and Kosztarab considered that all transverse bands of multilocular disc-pores were on the abdomen, whereas it is clear that the most anterior band is on the metathorax. The following combination of character-states diagnose the adult female of A. ornatus: (i) dorsum with four sizes of 8-shaped pores; (ii) large and intermediate-sized 8-shaped pores mainly in three transverse bands on dorsum; (iii) small 8-shaped pores present throughout rest of dorsum, but not intermingling with large or intermediate-sized pore bands; (iv) usually with four large 8-shaped pores on each side of posterior abdominal segments; (v) cribriform plates in a group of 2–5 on each side of abdominal segment IV; (vi) leg stubs absent; (vii) posterior stigmatic band not bifurcated; (viii) small convex closed pores present associated with each spiracle, (ix) multilocular disc-pores present across all abdominal segments and metathorax; (x) multilocular disc-pores also present in radial lines extending medially from each spiracle, and (xi) antennae without either a cone-like apex or setal cavity. (Hodgson & Williams, 2016) The structure of the metathorax of the male appears to be rather primitive, with a strongly sclerotized metapostnotum dorsally and with a sclerotized ridge medially on the metasternum (possibly representing the sternellum and median ridge of Theron?) and a long metaprecoxal ridge extending from the metapleural ridge medially almost to the sternal ridge. (Hodgson, 2020)
• Structure: Test of adult female is oval, dorsum strongly convex. There are several pairs of short, white, curved filaments on the median line. Test is purplish brown when early and red to reddish brown when older. Male puparium oblong, narrow and rounded at extremities, red to crimson. Adult female is grey and broadly oval. Adult male is uniformly dark brown with hyaline wings (Green, 1909a).
• Economic Importance: Narasimham (1987) states that a recent outbreak of C. ornatus on coffee in India seemed to be the result of indiscriminate use of pesticides.
• General Remarks: Lambdin & Kosztarab (1977a) give detailed description and illustration of adult female. Hamon & Kosztarab (1979) provide a detailed description and illustration of the first instar.
