A new Chorizococcus species (Hemiptera: Coccoidea: Pseudococcidae) from Taiwan with transferring Chorizococcus mirzayansi Moghaddam to genus Spilococcus Ferris

Abstract

A new mealybug species, Chorizococcus zoysiae sp. n., feeding on Zoysia tenuifolia (Poaceae), is described from Taiwan. This is the first record of a Chorizococcus species from Southeast Asia. Adult female, third-instar female, second-instar nymph and first-instar nymph were described and illustrated in this article. Keys are provides to (a) separate this new species from similar species of Chorizococcus and those of same genus on zoysiagrasses and (b) to identify instars of this new species. In addition, Ch. mirzayansi Moghaddam is transferred to the genus Spilococcus as S. mirzayansi (Moghaddam) comb. nov.
