Remarks

• Systematics: Pulvinaria enkianthi resembles P. aonoae Tanaka & Amano, 2004 in the distribution of type III ventral tubular ducts, the shape of the marginal setae, and the numbers of loculi in each multilocular pore. However, it differs from P. aonoae in having well-developed dermal areolations on the dorsum and more frequent dorsal tubular ducts. 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.
• Structure: See colour photograph in Kawai (1980, Figs. 6.29, a,b). Live appearance: adult female elongate oval, slightly convex. Dorsum brown to dark brown, with abundant granular white wax and a longitudinal narrow stripe devoid of wax even in individuals before oviposition. Ovisac short, 2–4 times as long as body; posterior of body not strongly lifted by ovisac. (Tanaka, 2020) Slide-mounted adult female body elongate oval, 2.9 (2.5–2.9) mm long, ca.2.0 (1.5–2.5) mm wide, margin with shallowindentation at each stigmatic cleft; anal cleft about 1/6 (1/5–1/7) body length. (Tanaka, 2020) The adult female morphology in Tanaka (2020) of P. enkianthi agrees well with the original description by Takahashi (1955). However, it differs slightly as follows (character states of the original description in parenthesis): (i) spiracular disc pores between each spiracle and stigmatic cleft numbering 18–60 (40 to over 50 in each band), (ii) marginal setae on each side between anterior and posterior stigmatic clefts numbering 11–17 (15–17), (iii) preopercular pores numbering 6–10 (referred as dorsal minute median pores, 15 at most in each individual), (iv) marginal setae 11–54 μm long (27–50 μm) and (v) body length 2.5–2.9 mm long (4 mm long). These morphological discrepancies are probably due to the morphological variation in the species or the quality of the microscope. (Tanaka, 2020)
