The genus Xenolecanium Takahashi is reviewed and transferred from the subfamily Myzolecaniinae to the Coccinae (tribe Paralecaniini). The type species Xenolecanium mangiferae Takahashi is redescribed, and Xenolecanium takabashii Kondo sp. nov. from Indonesia is described based on the adult female and first instar nymph. A taxonomic key is provided to separate adult females of the two species of Xenolecanium. Xenolecanium rotundum Takahashi is transferred to become the type species of a new monotypic genus, Takahashilecanium Kondo, which is also placed in the Paralecaniini. The morphological justification for placing Xenolecanium and Takahashilecanium in the Paralecaniini is discussed, and we provide a taxonomic key for separating both genera from all other members of the Paralecaniini.

The monophlebid scale insect Icerya aegyptiaca is reported for the first time in the Ryukyu Islands of Japan, where it was found in four islands: Kurima Island, Kuro Island, Miyako Island and Yonaguni Island. Icerya aegyptiaca was collected from 36 plant species belonging to 23 families. Information on the distribution and natural enemies of I. aegyptiaca and a key to separate known species of Icerya occurring in Japan are provided. [ABSTRACT FROM AUTHOR]

The genus Etiennea Matile-Ferrero is synonymized with Hemilecanium Newstead (Hemiptera: Coccidae). We base this decision on a morphological comparative study of adult females, adult males and first-instar nymphs (crawlers), including a phylogenetic analysis. We recovered a sister group relationship between the type species of the two genera, Etiennea villiersi Matile-Ferrero and Hemilecanium theobromae Newstead; that is, each was more closely related to the other than either was to other species in their respective genera. All species hitherto included in Etiennea are transferred to Hemilecanium: H. bursera (Hodgson & Kondo) comb. nov., H. cacao (Hodgson) comb. nov., H. candelabra (Hodgson) comb. nov., H. capensis (Hodgson) comb. nov., H. carpenteri (Newstead) comb. nov., H. cephalomeatus (Hodgson) comb. nov., H. combreti (Hodgson) comb. nov., H. ferina (De Lotto) comb. nov., H. ferox (Newstead) comb. nov., H. gouligouli (Hodgson) comb. nov., H. halli (Hodgson) comb. nov., H. kellyi (Brain) comb. nov., H. madagascariensis (Hodgson) comb. nov., H. montrichardiae (Newstead) comb. nov., H. multituberculum (Hodgson) comb. nov., H. petasus (Hodgson) comb. nov., H. sinetuberculum (Hodgson) comb. nov., H. tafoensis (Hodgson) comb. nov., H. ulcusculum (Hodgson) comb. nov., and H. villiersi (Matile-Ferrero) comb. nov. Keys to the adult females of all 26 species and known adult males and first-instar nymphs are provided. The adult males and first-instar nymphs of H. theobromae Newstead and E. villiersi Matile-Ferrero are for the first time fully described and illustrated. One new potential pest species of Hemilecanium, H. uesatoi Kondo & Hardy sp. nov., which was collected on three islands of the Ryukyu Archipelago, Japan, is described and illustrated based on the adult female, adult male and first-instar nymph. We discuss evidence that H. uesatoi is a new introduction to the Ryukyu Archipelago. The first-instar nymphs of Hemilecanium can be divided into two distinct morphological groups, the petasus group and the theobromae group. [ABSTRACT FROM AUTHOR]

The type speciesXenolecanium mangiferaeTakahashi is redescribed, andXenolecanium takahashiiKondo sp. nov. from Indonesia is described based on the adult female and first instar nymph. A taxonomic key is provided to separate adult females of the two species ofXenolecanium.Xenolecanium rotundumTakahashi is transferred to become the type species of a new monotypic genus,TakahashilecaniumKondo, which is also placed in the Paralecaniini. The morphological justification for placingXenolecaniumandTakahashilecaniumin the Paralecaniini is discussed, and we provide a taxonomic key for separating both genera from all other members of the Paralecaniini.
