Remarks

• Systematics: Subfamily: Coccinae A, Pulvinarini (Choi & Lee, 2019) Tanaka & Amano (2007a) redescribed and illustrated the adult female, based on syntype specimens. Tanaka & Amano (2007a) showed that previous redescriptions and illustration of adult female - by Ezzat & Hussein (1969), Williams & Kosztarab (1972), Hamon & Williams (1984), Kosztarab & Kozar (1988), Gill (1988), Hodgson (1994a), Granara de Willink (1999) and by Hodgson & Henderson (2000) - were not based on type material, and differed in some taxonomic characters from the 2007 redescriptions. Tanaka and Amano (2007a) did not determine which species had been misidentified as P. floccifera because of the difficulty of obtaining the type specimens of the species synonymized with P. floccifera. This situation subjectively invalidated the identity of P. floccifera. Because two or more species have been studied under the same (inappropriate) scientific name in the absence of type fixation, Tanaka & Kamitana determined that there was an urgent need to determine the misidentified species, or give another name to it/them, and to designate a lectotype of P. floccifera. This enables the separation of the misidentified species from the true P. floccifera, fixes its taxonomic identity and so restores nomenclatural stability. Abdel-Razak, et al., found that P. urbicola can be separated from P. floccifera by lacking submarginal tubercles (7-9 in P. floccifera) and by the 2 subapical seta located in the anal plate (3 in P. floccifera). Pulvinaria floccifera can be separated from P. camelicola in having (contrasting character states in P. camelicola in parenthesis): (i) Type III ventral tubular ducts on head few, marginal to submarginal (Type III ventral tubular ducts absent from head); (ii) dorsum without tubular ducts and dermal areolations (dorsum with a considerable number of dorsal tubular ducts and well-developed large dermal areolations). (Tanaka & Kamitani, 2022a)
• Structure: Dermal areolations absent; dorsal setae spiniform; preopercular pores consisting of a group of 48-83 pores in front of anal plates; dorsal tubular duct absent; marginal setae with frayed, bifurcate, or sharply pointed apices; pregenital disc-pores each with 4-8 (usually 7) loculi; spiracular dis-pores each with 5 loculi; 3 types of ventral tubular ducts; legs well developed each with tibio-tarsal articulation and articulatory sclerosis; antennae each with 6-8 (usually 8) segments. (Tanaka & Amano, 2007a) Live adult female elongate oval, more or less convex dorsally. Body yellow to yellowish green on dorsum. Dorsum without visible wax secretion before oviposition. Ovisac relatively long and flat, about 3–6 times as long as body; posterior part of body not strongly uplifted by ovisac. Slide-mounted adult female: Body elongate oval, 2.9 (1.9–3.9) mm long, 1.3 (0.9–2.7) mm wide, margin with a slight indentation at each stigmatic cleft and sometimes also near each eyespot; anal cleft approximately 1/6 (1/5–1/8) of body length. (Tanaka & Kamitani, 2022a)
• Biology: Takahashi (1955e) noted in Japan that generally one annual generation is developed, however two generations develop on Eurya at Tokyo.
• General Remarks: Lectotype designated in Tanaka & Kamitani, 2022a: collected 1870 on Camellia sp. by J.O. Westwood. 4 adult female paralectotypes also designated. Based on this information, it will take some time to identify which hosts, associates and location data need to be transferred to each of the species. We have done this to the best of our ability, but more taxonomic study is to be done. Therefore, some of this catalogue is unreliable at this time. (Barb Denno, March 18, 2022)
