Ceroplastes rubens

Adult female: body broadly oval and convex, with distinct, quite deep stigmatic clefts; length 3.5 (range 2.0–5.0) mm, width 3.0 (range 2.5–4.0) mm, height 2.0 (range 1.5–3.5) mm. Unmounted, with wax removed: oval, but with cephalic margin extending anteriorly; caudal process about as wide as long, length about 375–750 µm. Eyespots oval, not easy to see, rather displaced onto dorsum, each about 20 µm widest. Antennae: not described in detail. Legs much reduced in size, with trochanter and femur occasionally appearing fused; tibia and tarsus fused; trochanter+femur 33–45 µm, tibia+tarsus 40–60 µm, claw 7–10 µm. Dorsal setae each very short and parallel sided, with truncate apex, subequal to or shorter than width of basal socket, length 2.5–3.5 µm. Marginal setae similar to dorsal setae but perhaps slightly longer, up to 5 µm long. Stigmatic clefts deep, each with about 18–35 stigmatic setae arranged in 4 rows: a marginal line of 14–19 very round, bollard-like setae (each mainly 8–12 µm wide); a second row of 3 or 4 similar setae (each about 11–13 µm wide); a third row of 2 significantly larger bollard-like setae (each about 20 µm wide) plus 0 or 1 smaller setae; and at apex a much larger, bluntly pointed, spinose seta 40–55 µm long and 25 µm wide at base. Anal plates each 125–155 µm long, width of both plates combined 105–125 µm, each with 3 long flagellate dorsal setae. Anogenital fold with 3 pairs of setae on anterior margin plus 1–3 pairs of shorter hypopygial setae. Pregenital disc-pores abundant around genital opening (segment VII). Ventral microducts frequent throughout venter, particularly abundant near mouthparts, but scarce medially on thorax. Ventral tubular ducts absent.
