Remarks

• Systematics: it is concluded that all of Dr. Kuwana’s type specimens of P. hazeae have been lost. One of the specimens used in the redescription by Tanaka & Kamitani (2021) and collected from the same area (Hachiya, Buzen-shi) as the type locality of the species (Chikujo-gun, currently known as Buzen-shi, Chikujo-machi, Kouge-machi, and Yoshitomi-machi), has been designated as the neotype of P. hazeae for the purpose of taxonomic stability. The morphology of this type specimen is almost consistent with the original description. Pulvinaria hazeae is similar to P. idesiae in having: (i) well-developed ventral setae on the medial area of most thoracic and abdominal segments, (ii) a large, mostly rounded body; (iii) in lacking dorsal tubular ducts, and (iv) in having similar dorsal coloration (dark brown with irregular whitish or yellowish spots). However, it differs from P. idesiae by the following character states (character states of P. idesiae in brackets): (i) an extremely long, thin-walled ovisac (ovisac relatively short and thick walled); (ii) having multiple multilocular pores between antennal bases (lacking pores on the head); and (iii) in lacking type III ventral tubular ducts on submarginal area anterior to anterior stigmatic furrows (having type III ventral tubular ducts on submarginal area anterior to interior stigmatic furrows). Pulvinaria hazeae can be separated from other Pulvinaria species described in this study, and from P. vitis, by the absence of dorsal tubular ducts and dorsal submarginal tubercles, the condition of dermal areolation, body shape, multilocular pore distribution, type III ventral tubular duct distribution, and the number of loculi in each multilocular pore. (Takana & Kamitani, 2021b)
• Structure: Body of adult female broadly oval to circular, slightly convex; dorsal surface dark brown, covered with irregular whitish or yellowish spots; thin-walled ovisac produced from ventral surface of abdomen, extremely long, often more than 100 mm long. Eggs reddish white, visible through thin-walled ovisac. (Takana & Kamitani, 2021b)
