Remarks

Systematics: Discussion, Williams (1987) mentioned three variants of this species, one of which was collected from Madeira, one collected from Colombia on Manihot esculenta (Euphorbiaceae) and one collected from Louisiana, Baton Rouge (U.S.A), on Althaea sp. (Malvaceae). Kaydan, et al. found that the distribution and frequency of the multilocular pores on the dorsum and tubular ducts on the venter also varied. P. gossypii and P. madeirensis differ from P. franseriae and P. psidiarum by lacking dorsal cerarii on the abdomen and from each other by the presence in P. gossypii of dorsal submedial multilocular pores on the mesothorax that are absent from P. madeirensis, as was also recorded by Williams & Granara de Willink (1992). Their phylogenetic analysis, based on morphology, recovered P. gossypii and P. madeirensis in the same clade, although nesting in separate subclades (Granara de Willink & Szumik 2007). Watson, et al. 2017 morphological analysis shows that the absolute presence versus absence of dorsal multilocular pores on the thorax, is not sufficient to reliably separate P. gossypii from P. madeirensis. We suggest instead that pore counts could be used, with P. gossypii as currently understood having a total of more than 70 dorsal multilocular pores on the pro- and mesothorax versus P. madeirensis having fewer than five. However, this character does not allow separation of the cryptic species evidenced by their DNA analysis within the P. madeirensis complex. Three haplotypes (named H1, H2, and H3) were detected in the COI gene of P. madeirensis in GenBank. Individuals of haplotype H1 were from China [accessions KY372757, KY373159, KY372819, KY372762 (Wang et al., 2016) and KP692615, KP692619 (Ren et al., 2018)] and the Seychelles [accession KY372717 (Ren et al., 2017)]. Haplotype H2 was described from the USA [accessions KU550064 (Ellenrieder et al., 2016) and KY192523 (Watson et al., 2017)], Spain [accession JF714207 (Beltrà et al., 2012)] and France [accession JQ085561 (Abd-Rabou et al., 2012)], while haplotype H3 is from the USA [accession KY372827 (Ren et al., 2017)].
Structure: Colour photograph of adult female by Matile-Ferrero et al. (2004). Phenacoccus madeirensis has a grey oval body covered by thin, white, mealy wax, with red legs and dark dorso-submedial bare spots on intersegmental areas of the thorax and abdomen. These areas form 1 pair of dark longitudinal lines on the dorsum. The ovisac covers the entire dorsum, with 18 pairs of lateral wax filaments, the posterior pairs being the longest. They were approximately the length of the body or a little shorter. (Papadopoulou & Chryssohoides, 2012)
Biology: Phenacoccus madeirensis normally reproduces sexually, although there have been some reports of reproduction by parthenogenesis, possibly referable to some other group members (Kondo, et al., 2022) Life history, under laboratory conditions, in Sicily studied by Longo et al. (1995). In Sicily it develops 5-6 generations per year (Sinacori, 1995). Ho et al. (2009) identified and synthesized the female sex pheromone.
Economic Importance: This mealybug is common on cassava, causing, however, little damage. It is often injurious to potatoes in Peru. It is extremely common in Africa, probably been introduced there from Neotropical region (Williams & Granara de Willink, 1992). In 2010 and 2011, a serious mealybug infestation was observed on Ocimum basilicum (large leaf or sweet basil) in Greece. (Papadopoulou & Chryssohoides, 2012)
General Remarks: Description and illustration of adult female by Williams (1958, 1987c), Williams & Granara de Willink (1992), Williams (2004a) and by Granara de Willink & Szumik (2007). The redescriptions and illustrations of the adult female given by Ferris in Zimmerman (1948), Ferris (1950b) and by McKenzie (1967), and of the adult male by Beardsley (1960) (of Hawaiian population) and Beardsley (1962) (of Californian populations) under the name of P. gossypii probably represent P. madeirensis. Likewise, the records of P. gossypii from Hawaii by Ferris in Zimmerman (1948) and by Beardsley (1960), and from Guam by Beardsley (1975) are probably misidentifications of P. madeirensis.
