New species of Lonchaeidae (Diptera: Schizophora) from Japan and a re‐evaluation of genus Setisquamalonchaea Morge

Three new species of Lonchaeidae are described from material reared from fig syconia in Japan: Silba inubiwa sp. nov., S. ishigaki sp. nov. and S. japonica sp. nov. Based on the taxonomy of these and similar species the boundaries of the genus Silba are re‐evaluated, and, as a result, it is considered that Setisquamalonchaea Morge is synonymous with Silba Macquart. A revised key and generic notes on the tribe Lonchaeini are provided.     

Host range expansion by Rhopalomyia yomogicola (Diptera: Cecidomyiidae) from a native to an alien species of Artemisia (Asteraceae) in Japan

In 2001, subconical galls were found on the leaves of an alien Artemisia species (Asteraceae) in Ibusuki City, Kagoshima Prefecture, Japan. These galls were quite similar to those induced by Rhopalomyia yomogicola (Diptera: Cecidomyiidae) on Artemisia princeps, Artemisia montana, and Artemisia japonica in Japan. The morphological features of the pupal head and molecular sequencing data indicated that the gall midge from the alien Artemisia was identical to R. yomogicola. Usually, galling insects do not expand readily their host range to alien plants, but R. yomogicola is considered to have expanded its host range to the alien Artemisia by its multivoltine life history trait and oligophagous habit across two different botanical sections of the genus Artemisia. Adult abdominal tergites and sternites and immature stages of R. yomogicola are described for the first time and detailed biological information is presented.     

Chrysosphaerella (Pseudochrysosphaerella)solitaria,spec. nova (Chrysophyceae)

A new unicellular species of the genusChrysosphaerella (Chrysophyceae) was found in fresh-water ponds in Switzerland, Japan, and the U.S.A. It is described asC. solitaria. The genus is divided into two subgenera:Chrysosphaerella, comprising the colonial species, andPseudochrysosphaerella, the unicellular ones.     

Taxonomic studies of nectrioid fungi in Japan. III. The genus <Emphasis Type="Italic">Cosmospora</Emphasis>

Seven species of the genus Cosmospora collected in Japan are reported in this article. Among them, Cosmospora japonica is described as a new species. Cosmospora henanensis, C. rishbethii, and C. triqua, all of which are known only from their type localities, are added to the Japanese mycobiota. The other species, C. chaetopsinaecatenulatae, C. diminuta, and C. peponum, are new records for Japan. Additional distribution records are given for Cosmospora species hitherto known in Japan.     

Taxonomy and phylogeny of Leptopilina species (Hymenoptera: Cynipoidea: Figitidae) attacking frugivorous drosophilid flies in Japan,with description of three new species

Despite the intensive use of the Leptopilina genus and its drosophilid hosts as model systems in the study of host–parasitoid interactions, the diversity and distribution of the species occurring in the Asian region remain elusive. Here we report the phylogeny of Japanese Leptopilina species attacking frugivorous drosophilid flies, based on COI, ITS1 and ITS2 sequences. Consistent with molecular data, hybridization experiments and morphological examination, five species were recorded in Japan: Leptopilina heterotoma, L. victoriae and three new species, two occurring in the Ryukyu archipelago, L. ryukyuensis and L. pacifica, and another species, L. japonica, distributed in Honshu and Hokkaido. Leptopilina japonica is further divided into two subspecies, L. j. japonica occurring in Japan, and L. j. formosana occurring in Taiwan. According to these results, we discuss the evolution, speciation and colonization history of Japanese Leptopilina species.     

<Emphasis Type="Italic">Cacopsylla biwa</Emphasis> sp. nov. (Hemiptera: Psyllidae): a new pest of loquat <Emphasis Type="Italic">Eriobotrya japonica</Emphasis> (Rosaceae) in Japan

A new psyllid species, Cacopsylla biwa Inoue, sp. nov., is described from Tokushima Prefecture, Shikoku, Japan. This new species develops only on Eriobotrya japonica (Thunb.) Lindl. (Rosaceae), causing severe damage to its fruits and flowers. It is strongly suspected that C. biwa is an alien species. Morphological similarities and host-plant relationships indicate that C. biwa is most closely related to Cacopsylla eriobotryae (Yang) comb. nov. (transferred from Edentatipsylla Li), which occurs in Taiwan and feeds on Eriobotrya deflexa (Hemsl.) Nakai. Morphological diagnostic characteristics of C. biwa and differences from the other congeners are discussed. Information is provided on the biology and life cycle of the new species.     

New species of the genus Salganea (Blattaria, Blaberidae, Panesthiinae) from Myanmar, with molecular phylogenetic analyses and notes on social structure

A new species of the genus Salganea is described from Mount Victoria, Chin State, Myanmar under the name of Salganea matsumotoi sp. nov. Morphological investigation suggests that this species belongs to the S. nigrita species group. The inferred molecular phylogenetic tree indicates that S. matsumotoi is most closely related to the taxa S. incerta, S. taiwanensis, S. gressiti and S. esakii, distributed in Thailand, Taiwan and Japan, all of which belong to the S. nigrita species group. Social structural data suggest that this species is subsocial, and in contrast to other studied species in the genus, potentially has more than one reproductive episode.     

Pleosporales in Japan (3). The genus Massarina

 Twelve species of the genus Massarina collected from Japan are reported in this article. Among them, 4 new species, M. constricta, M. japonica, M. submediana, and M. uniserialis, are described, illustrated, and compared to similar species. Two species, M. scirpina and M. ryukyuensis, are described as new combination, and 4 species, M. arundinariae, M. fluviatilis, M. peerallyi, and M. rubi, are reported from Japan for the first time. One bambusicolous species, Metasphaeria tuberculosa, is considered to be a synonym of Massarina bambusina.

Revision of the genus Thambemyia Oldroyd (Diptera: Dolichopodidae) with description of a new subgenus

The genus Thambemyia Oldroyd is revised. Five species are recognized. Three new species –T. bisetosa, T. bruneiensis and T. hui– are described, and T. pagdeni Oldroyd, 1956 is redescribed. A new subgenus is founded for one new Japanese species, T. (Prothambemyia) japonica. A key to all known species of the genus is provided. Their distributions are also discussed.     

Neoholmesia,a new genus of the delesseriaceae (Rhodophyta)

A new genus,Neoholmesia, is established on the basis ofHolmesia japonica (Okamura) Okamura. Neoholmesia that is distributed in the Northern Honshu and Hokkaido, Japan, should be placed in theMembranoptera group described by Kylin because of its apical segmentation of the thallus, and because it differs from the genusHolmesia in that tetrasporangia are found scattered randomly over the surface of the main thallus, and in that it bears carposporangia in chains. Dedicated to Prof. Shoichiro Usami celebrating his sexagenary birthday.     

Halosarpheia japonica sp. nov. (Halosphaeriales, Ascomycota) from marine habitats in Japan

A new Halosarpheia species, collected from driftwood from Hakkeijima beach, Yokohama, Japan, is described and illustrated and is compared with other species of the genus. The new fungus was growing together with its anamorph on a piece of decaying wood. SSU and LSU rDNA sequences for both morphs were 99% similar. Phylogenetic analyses of SSU and LSU rDNA sequences of the both morphs confirm their anamorph–teleomorph relationship and placed the new fungus in the Halosarpheia sensu stricto clade with high statistical support. Halosarpheia japonica is characterized by its polar appendage that is initially enclosed in a cellular sheath and dissolves in water, the appendage then swells to form a huge tree-like structure. The other three species currently included in Halosarpheia sensu stricto differ from H. japonica by having two polar appendages that uncoil in water to form long filaments.     

Parasitoid spectrum (Hymenoptera: Braconidae; Aphelinidae) of the soybean aphid Aphis glycines (Homoptera: Aphididae) in Japan and Indonesia (Java and Bali)

Aphidiine and aphelinid parasitoids collected from the soybean aphid, Aphis glycines, on Glycine max in Japan and Indonesia (Java and Bali) were identified to clarify the parasitoid spectrum of the aphid there. Nine parasitoid species from Japan (Aphidiinae: Aphidius gifuensis, Aphidius sp., Binodoxys communis, Diaeretiella rapae, Lipolexis gracilis, Lysiphlebia japonica; Aphelinidae: Aphelinus asychis, A. gossypii, A. varipes) and two parasitoid species from Indonesia (B. communis, A. gossypii) were found to be associated with A. glycines.     

The taxonomic status ofSedum telephium and its allied species (Crassulaceae)

The taxonomic status ofSedum Telephium and its allied species (Crassulaceae-Sedoideae) is discussed, and a new genus,Hylotelephium, is recognized. Under the genus, 27 new combinations are proposed and one new species,H. callichromum, from Central Asia is described. This study has been supported partly by Grants-in-Aid for Fundamental Scientific Research by the Ministry of Education of Japan, No. 034047 in 1975 and 1976.     

The Larval Stage of Chilostigma sieboldi McLachlan (Trichoptera,Limnephilidae), with Notes on Taxonomy and Distribution

The larva of Chilostigma sieboldi McLachlan is described. This is the first positive association of adults and larvae in the genus Chilostigma, which involves only two species in the boreal region. We recorded and confirmed the Holarctic species C. sieboldi from Kushiro Mire in eastern Hokkaido by close examination of male and female genitalia. In Japan this species has been collected only from Kushiro Mire.     

A revision of the phoretic deutonymphs (hypopi) of the genus Sennertia Oudemans, 1905 (Acari,Astigmata, Chaetodactylidae)

Summary The genus Sennertia Oudemans, 1905 (Acari, Chaetodactylidae) is revised. Up to now, 49 species have been described in this genus, almost all from their hypopial stage. Adults are known only for four species. The adults live in the nests of bees, mainly Xylocopidae, and their heteromorphic deutonymphs ( = hypopi) are phoretic on the bees. The parasitic role of these mites is not known but they probably feed on the bee larvae as do the members of the allied genus Chaetodactylus wich are parasitic in the nests of Megachilidae. The holotypes or lectotypes of 35 species have been examined and most of them are redescribed and redepicted. Four species have been placed in synonymy: S. moandensis Fain, 1971 with S. morstatti Vitzthum, 1914; S. xylocopae (Donnadieu, 1868) with S. cerambycina (Scopoli, 1763); S. sumatrensis Oudemans, 1924 with S. horrida (Vitzthum, 1912); S. donaldi Turk, 1948 with S. argentina Vitzthum, 1941. The genus Sennertia is redefined from the hypopial stage and four new subgenera (Afrosennertia, Asiosennertia, Amsennertia and Spinosennertia) and two new species S. (Asiosennertia) vitzthumi and S. (Asiosennertia delfinadoae) are described. A key to the species is given. ac]19810331     

The genus Ponticulomyces (Physalacriaceae, Agaricales) from Japan

Two species of the genus Ponticulomyces collected from Japan for the first time are described and illustrated. Ponticulomyces kedrovayae is characterized by its lamellae staining yellow when bruised and in age, stipe lacking an annulus and a pseudorhiza, scattered pileal hairs, and large amygdaliform basidiospores. It mainly occurs on dead wood of Fagus crenata. Ponticulomyces orientalis is characterized by its scattered pileal hairs and broadly ellipsoid to ellipsoid basidiospores. It was collected mostly on dead wood of Cameria japonica.     

The genus Phyllomyza Fallén (Diptera: Milichiidae) from Japan, with descriptions of four new species

The Japanese species of the genus Phyllomyza Fallén are revised. Four new species, Phyllomyza kanmiyai sp. nov., P. amamiensis sp. nov., P. proceripalpis sp. nov. and P. japonica sp. nov., are described and illustrated. P. securicornis Fallén is recorded from Japan for the first time. A key to the Japanese species of Phyllomyza is presented.     

Dermaphis coccidiformis sp. nov. (Hemiptera), an aphid species with asymmetrically sclerotized apterae and “winter alates”

Dermaphis coccidiformis sp. nov. (Hormaphidinae: Nipponaphidini) is described from Japan. Apterous adults of the species were found between winter buds (or between a winter bud and a leaf petiole) of the evergreen oaks Quercus glauca, Q. myrsinifolia and Q. salicina. Their morphology is peculiar in that their tergites are heavily sclerotized only in the part that seems to have been exposed to sunlight. The new species is also peculiar in that nymphs to be alates (sexuparae) were found on the upper surfaces of leaves of the host oak only during winter, from December to March or early April, before the bud break of the oak. Our molecular phylogenetic analysis indicated that the new species is closely related to Dermaphis spp., therefore it was placed in the genus. The analysis incidentally indicated that “Dinipponaphis” autumna, a monoecious species forming galls on Distylium racemosum, was included in the clade of the genus Dermaphis, and therefore it was transferred to this genus.
