Remarks

• Systematics: urn:lsid:zoobank.org:act: 2272018E-C642-4FDE-A431-2C72F2C7980F Paratypes: PENINSULAR MALAYSIA: Malacca, Kendong, in hollow stems of Macaranga triloba [now correctly named M. bancana], date not given, coll. I.H. Burkill, 2(2) (USNM) Adult females of C. caviramicolus can be distinguished from all other species of Coccus known from Macaranga by having the combination of (i) extremely short dorsal setae (appearing absent); (ii) marginal setae ≤40 μm long and each with a fimbriate apex; (iii) anal plates together pyriform in shape; and (iv) the numerous (≥15), very short (5–8 μm) setae on each plate. They are most similar to the adult females of C. pseudotumuliferus, C. secretus and C. tumuliferus in having very short dorsal setae of length mostly less than two times width of setal socket, but differ in that their marginal setae are apically fimbriate (mostly tapering to a point in the other three species) and their anal plates together are pyriform (anal plates together are quadrate to subcircular in other three species). (Gullan, et al., 2018)
• Structure: Unmounted material. “Flat, broad oval, approaching circular, dull brown, central area darker, dull or faintly shining, without or with a very slight secretionary coating; ..” (Morrison 1921: 659). Slide-mounted adult female oval to elongate oval, 1.8–3.4 mm long, 1.4–2.8 mm wide.
• 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 adult female by Morrison (1921). Redescription and illustration in Gullan, et al., 2018.
