Remarks

• Systematics: Ceroplastes singularis differs from most other species in the C. rusci-group in having: (i) stigmatic setae around of the entire margin (restricted to near stigmatic clefts on C. rusci and related species, never forming a complete band anteriorly on head); and (ii) ventral tubular ducts absent (otherwise only totally absent on C. balachowskyi, C. galeatus and C. ghesquierei. C. rufus also has stigmatic setae extending around most of the margin but the stigmatic setae are all rather sharply pointed on C. singularis rather than roundly conical, as on C. rufus.
• Structure: Unmounted material. C. singularis: "Test of adult female hemispherical; thin and very hard; texture fairly smooth; dorsum with a faintly indicated plate, almost circular in outline, with indications also of 3 lateral plates; colour dirty ochreous." (Newstead, 1910). Unmounted material. C. hololeucus: "Immature adult females flattish, disc-like in shape; wax test faintly divided into plates: three bilateral, 1 cephalic and 1 dorsal; at the centre of each of them there is a small and elongate boss; colour in the test in material stored in alcohol evenly white; wax rather brittle in texture" (De Lotto, 1969). Mounted material. Body broadly elliptical to roundly circular, length 1.3-2.4 [about 2] mm, width 0.9-1.75 [?] mm. Dermal processes obscure. (Hodgson & Peronti, 2012)
