Remarks

• Systematics: urn:lsid:zoobank.org:act:30644D80-511B-4645-9BB3-FBFD0D4AC770 Adult females of C. macarangae can be distinguished from all other species of Coccus known from Macaranga by having the combination of (i) sharply spinose dorsal setae each mostly 25–30 μm long but a few can be up to 40 μm long; (ii) marginal setae in a single row, with each seta 10–30 μm long with apex fimbriate to sharply spinose; and (iii) anal plates each with 3 or 4 setae, each mostly 20–30 (rarely up to 40) μm long. Adult females of C. macarangae are most similar to the adult females of C. circularis in having fewer than 10 setae on each anal plate and many marginal setae that are apically fimbriate or bifurcate, but differ from C. circularis in that the dorsal setae are sparser, generally longer (up to 40 μm long) and less slender and the preopercular pores are more numerous (20–50) and usually larger (5–11 μm wide) in C. macarangae (dorsal setae 15–30 μm long with flagellate apices and preopercular pores scarce (≤10) and 5–6 μm wide in C. circularis). (Gullan, et al., 2018)
• Structure: Adult female body short oval, pale reddish brown, darker in middle, flat, with faint radiating ridges near margin; dorsal surface appearing naked, possibly with a very thin film of secretion. (Morrison, 1921) Slide-mounted adult female body oval to elongate oval, body often truncated anteriorly on head, 2.0–4.4 mm long, 1.3–3.1 mm wide. (Gullan, et al., 2018) First-instar nymph. Slide-mounted material (n=10, all from Brunei, Borneo). Body oval to elongate oval, body often truncated anteriorly on head, 370–460 μm long, 205–280 μm wide. (Gullan, et al., 2018)
• Biology: Occupies the hollow stems of myrmecophytic species of Macaranga (Euphorbiaceae) in association with ants of the genus Crematogaster (Heckroth et al., 1998)
• General Remarks: Description of the adult female given by Morrison (1921). Detailed redescription in Gullan, et al., 2018.
