Ceroplastes destructor

Adult female body oval, rather convex, with shallow stigmatic clefts. Length about 3.0–6.0 mm, total width of mounted specimen 2.0–3.5 mm. Dorsal setae cylindrical or slightly knobbed, each slightly longer than width of basal socket (length 6.5–7.5 µm). Marginal setae strongly setose, each about 20 µm long. Submarginal setae more frequent than marginal setae, each 11–15 µm long. Stigmatic clefts shallow, each with a compact triangular to oval group of stigmatic setae; each group with 44–90 setae, of which about 11–22 along margin; largest setae each 20–27 µm long, 18–22 µm wide at base, rather longer than wide; smallest setae 8 µm long, 6.0–8.0 µm wide at base; setae roundly to sharply cone-shaped, most with a broad basal flange. Anal plates each with 2 pairs of long dorsal setae (each 50–65 µm long, blunt apex sometimes appearing capitate), plus a shorter dorsal seta near apex (about 25 µm long) and a small apical seta (13–20 µm long). Anal lobes each with a single longer seta about 50 µm long on ventral surface of caudal process. Preopercular pores slightly convex, in a transverse band of 9–14 pores. Derm with eight clear areas, each without setae. Eyespots each about 35 µm wide, usually with 1 or 2 marginal setae near eyespot margin. Ventral tubular ducts absent from cephalic region but rather abundant submedially on abdomen associated with anogenital fold and medially on segments IV–VI.
