Genetic distances and generic placement of Ph. hakeae  

Molecular analysis showed the COI sequences of 610 base pairs of the Australian and Californian specimens to be identical. The sequenced COI portion of Phenacoccus hakeae   differs by 11–15 % from similar sequences of other Phenacoccus   species ( Ph. aceris (Signoret)   , Ph. avenae Borchsenius   , Ph. baccharidis Williams   , Ph. madeirensis Green   , Ph. parvus Morrison   , Ph. peruvianus Granara   de Willink in: Granara de Willink & Szumik, Ph. solani Ferris   , Ph. solenopsis Tinsley   ) and by 9–14 % from those of Paracoccus   species ( Pa. burnerae (Brain)   , Pa. ferrisi Ezzat & McConnell   or nr., Pa. gillianae   von Ellenrieder & Stocks, Pa. marginatus Williams & Granara   de Willink) available on GenBank and in the CSCA dataset.

The TaxonID tree-based identification tool in BOLD (Ratnasigham & Hebert 2013) shows Ph. hakeae   grouping with Crisicoccus matsumotoi (Siraiwa)   (8.5–10 % difference) known from South-East Asia and the Oriental region, and Vryburgia transvaalensis (Brain)   (9.9–10 % difference) from southern Africa.

Our Neighbor-Joining analysis performed using available sequences in the CSCA database and some selected sequences from GenBank shows Ph. hakeae   grouping with members of the subfamily Pseudococcinae with good support, and in a subgroup including Balanococcus takahashii McKenzie   and Crisicoccus matsumotoi   with low support. It also shows the genus Phenacoccus   forming a separate grouping ( Fig. 1 View FIGURE 1 ), as is expected because Phenacoccus   belongs to the subfamily Phenacoccinae (Hardy et al. 2008).
