Remarks

• Systematics: Pulvinaria flava resembles P. torreyae Takahashi, 1956, in having occasional marginal setae with bifid apices and in the number of loculi in each multilocular pore. However, it can be distinguished from P. torreyae in lacking marginal setae with fimbriate and spatulate apices, in having a few ventral tubular ducts of type III between the metathoracic spiracular pore band and the area near each antenna, and a more rounded body shape. Important diagnostic morphological character states of this species and a comparison between them and those of the type species of the genus, P. vitis (Linnaeus, 1758) are summarized in Tanaka, 2020. The adult female morphology of the specimens of P. flava described here agree well with Takahashi’s (1955) original description, but differ slightly from the original description as follows (character states of the original description in parenthesis): (i) spiracular disc pores between each spiracle and stigmatic cleft numbering 29–46 (35 to over 50 in each band), (ii) preopercular pores numbering 7–18 (referred as dorsal minute median pores, 15–21 in each individual), (iii) number of marginal setae on each side between anterior and posterior stigmatic clefts numbering 16–27 (18–20), and (iv) shape of marginal seta tips and length of marginal setae 17–75 μm long (27–75 μm). These morphological discrepancies are probably due to the morphological variation of the species or the quality of the microscope. (Tanaka, 2020)
• Structure: Slide-mounted adult female body oval, 3.5 (3.5–3.7) mm long, 2.6 (2.5–2.8) mm wide, margin with shallow indentation at each stigmatic cleft; anal cleft about 1/7 (1/6–1/7) body length. (Tanaka, 2020)
