  1. The rosae group and the megaloba group of Aulacaspis (Sternorrhyncha: Coccoidea: Diaspididae)

    Takagi, Sadao
    Nine species of Aulacaspis recorded from plants of the family Rosaceae or the Ericaceae and another species from a supposedly ericaceous plant are mentioned in an annotated list. Five of them and four new species associated with plants of the mentioned families are lumped together under the rosae group, and two others, associated with plants of the rosaceous genus Rubus, under the megaloba group. The rosae group is divided into two subgroups: one of them is composed of A. mali, A. ericacearum, A. sorbi, n.sp., and the broadly distributed A. rosae, the former three species being restricted in distribution to...

  4. Description of some morphs on the primary host of Micromyzodium kuwakusae (Uye) (Hemiptera: Aphididae)

    Sugimoto, Shun'ichiro
    Field observation, morphological study, and transfer experiments showed that yellow aphids on Loropetalum chinense (Hamamelidaceae) are that primary host generations of Micromyzodium kuwakusae (Uye) that has been reported to be associated with Fatoua villosa (Moraceae). The present study showed that M. kuwakusae alternates host plants between L. chinense as a primary host and F. villosa as a secondary host. Some morphs on the primary host of M. kuwakusae are described for the first time, and the life cycle is summarized.

  7. Revision of the genus Yamatocallis Matsumura in Japan (Hemiptera: Aphididae)

    Sugimoto, Shun'ichiro
    The aphid genus Yamatocallis Matsumura, 1917 in Japan is revised. the following 5 species, Y. nikkoensis sp. nov., Y. hirayamae Matsumura, Y. tokyoensis (Takahashi), Y. acericola Higuchi and Y. takagii (Takahashi), are described with their host records and distributions. Among the previously known species, the fundatrices of Y. hirayamae and Y. tokyoensis, and the sexual morphs of Y. acericola and Y. takagii are described for the first time. A key to Japanese species is provided. Moreover, based on the collection data of each aphid, the host preference is discussed.

  10. A taxonomic review of the phytophagous ladybird beetles of the Diekeana alternans complex (Coleoptera: Coccinellidae: Epilachnini) with descriptions of eight new species and one new subspecies

    Ohta-Matsubayashi, Yuri; Katakura, Haruo; Kahono, Sih; Kikuchi, Namiki
    A group of phytophagous ladybird beetles utilizing diverse host plants in South and Southeast Asia was reviewed as the Diekeana alternans complex. Ten species (one with two subspecies) including seven new species and one new subspecies were described or redescribed under this species complex. Diekeana hopeiana (Miyatake) was synonymized with D. grayi (Mulsant). Two other species were also incorporated into this complex based on literature information. Additonally, another species closely related to this species complex was described as new to science. Species of the D. alternans complex constituted a part of the Diekeana admirabilis group and were characterized by a...

  17. First description of the male of Manicapsocus (Psocodea: ‘Psocoptera’: Electrentomidae)

    Yoshizawa, Kazunori
    The male of Manicapsocus alettae Smithers was recorded for the first time and its genital morphology was described and illustrated. This also represented the first report of the male of the genus. The highly specialized phallosome of M. alettae supported its close relationship with Epitroctes Mockford and Nothoentomum Badonnel, as previously suggested from general and female genital characters.

  19. Four armoured scale insects from Australia, South Africa, and Mexico : Quarantine interceptions in Japan (Sternorrhyncha: Coccoidea: Diaspididae)

    Takagi, Sadao
    Four species of armoured scale insects intercepted at quarantine inspection in Japan are recorded, and remarks are made about some taxonomic questions they arouse. One of the species, found on Xanthorrhoea sp. imported from Australia, is identified with Chionaspis xanthorrhoeae Fuller and trasferred to Poliaspis. Another species, on Chamelaucium from Australia, is very close to Poliaspis ceraflora Hardy and Henderson. A third species was collected on cut flowers of Paranomus, Serruria, and Berzelia from South Africa, and is identified with Rolaspis lounsburyi (Cooley). The fourth species, Opuntiaspis sp., was found on cactus fruits from Mexico, and is apparently different from...
