Remarks

• Systematics: First-instar nymphs of T. coffeae have five segmented antennae and resemble other species of Toumeyella. (Kondo, 2013) Slide-mounted adult female T. coffeae can be differentiated from other species of Toumeyella by possessing the following combination of character states: (i) perivulvar pores small, about same size as spiracular pores; (ii) all leg segments fused, except for claw; (iii) antennal segmentation indistinct, 2–4-segmented; (iv) stigmatic clefts well developed; with 3 stigmatic spines in each cleft, median spine slightly longer than lateral spines; (v) anal plates each with 1 or 2 apical setae; (vi) marginal setae sharply spinose, with parallel sides, near apex abruptly tapering to a point; (vii) a small sclerotic area. (Kondo & Garonna, 2022) often present just anterior to anal plates; and (viii) ventral tubular ducts restricted to perivulvar area.
• Structure: Body convex. Derm orange, brown to greyish green in color, with dark tesselations, but usually with mid-dorsum very lightly or not mottled; anal plates dark to reddish brown. Mature insects 1.5-4.2 mm in diameter, (Kondo, 2013). Slide-mounted adult female body oval to elongate oval, often narrowing anteriorly, 1.7–5.3 mm long, 1.1–4.1 mm wide; anal cleft about 1/4 of body length. Dorsal setae sharply spinose, straight or slightly curved. Dorsal microducts with a bilocular opening, each with a long terminal filament, scattered throughout dorsum. (Kondo & Garonna, 2022)
• Biology: This species is sexual because second-instar males have been found in one infestation. These coccids live and feed on roots and on underground parts of stems. (Kondo, 2013)
• Economic Importance: Toumeyella coffeae is the only species in the genus known from the roots and root crown of its host. (Kondo and González, 2018) Large populations of the scale may cause various symptoms, including chlorosis, leaf fall, wilting of twigs and, in some cases, plant death. (Kondo & Garonna, 2022)
