Pulvinaria tenuivalvata

Adult female body very elongate, oval, narrow at both ends, convex with cephalic region flattened, 3.4–6.5 mm long, 1.5–2.5 mm wide. Body colour varies from pale crimson to flesh-coloured with two irregular longitudinal bands of bright crimson on dorsum. Anal cleft rather shallow, 0.70–0.74 mm long. Antennae present. Marginal setae numerous, slender and pointed, with well-developed basal sockets, distributed in one row with 12–18 setae on each side between anterior and posterior stigmatic clefts, mostly about 35–40 µm long, a few approximately 20 µm long; longest setae similar in length to median stigmatic setae. Two pairs of long anterior marginal setae (median pair each nearly 45 µm long, submedian pair each around 65 µm long) and three pairs of long lateral margin setae, 55–65 µm. Spiracular setae: median seta short, stout, pointed, 25–40 µm long; lateral spiracular setae variable, each 15–20 µm long, pointed. Claw digitules unequal, one twice diameter of other, both slender, of same length, each slightly knobbed at apex, 35–40 µm long. Combined length of hind trochanter plus femur about 200–220 µm. Dorsal setae short, strong, spiniform. Anal ring with four pairs of long setae and two rows of pores. Prevulvar setae long, one pair on each of three prevulvar segments. Ventral tubular ducts of type I in a submarginal band, 4–6 ducts wide, numerous around entire body except caudal area and head region where sparse.
