Type studies of <Emphasis Type="Italic">Pleurotus</Emphasis> reported from Japan

Eight type specimens of Pleurotus reported from Japan were examined. Four new combinations, Marasmius alopecius, Omphalotus guepiniformis, Marasmiellus leiophyllus, and Hohenbuehelia squamula, are proposed. Pleurotus cyatheae is accepted in the original genus. The following species are synonyms: Pleurotus harmandii, a synonym of Omphalotus guepiniformis; P. minutoniger, a synonym of Resupinatus striatulus; and P. pulchellus, a synonym of Hohenbuehelia tremula. Omphalotus japonicus (= Lampteromyces japonicus) is a synonum of O. guepiniformis.     

Validity of <Emphasis Type="Italic">Scorpaena jacksoniensis</Emphasis> and a redescription of <Emphasis Type="Italic">S. cardinalis</Emphasis>, a senior synonym of <Emphasis Type="Italic">S. cookii</Emphasis> (Scorpaeniformes: Scorpaenidae)

The Scorpaena cardinalis complex, including S. cardinalis, S. jacksoniensis and S. orgila, is defined. The genus Ruboralga (type species: S. jacksoniensis) is regarded as a junior synonym of Scorpaena. Scorpaena jacksoniensis Steindachner 1866, previously treated as a junior synonym of Scorpaena cardinalis Solander and Richardson 1842, is regarded here as a valid species. Scorpaena cookii Günther 1874, previously treated as a valid species, is regarded here as a junior synonym of S. cardinalis. Thus, recent recognition of the two Australasian scorpionfishes, i.e., S. cardinalis and S. cookii, are re-identified in this study as S. jacksoniensis and S. cardinalis, respectively. Scorpaena plebeia Solander 1842 is regarded as a junior synonym of S. cardinalis. Scorpaena jacksoniensis is distributed along the east coast of Australia from southern Queensland to eastern Victoria, whereas S. cardinalis occurs around northern New Zealand, the Kermadec Islands and offshore islands of the Tasman Sea. A neotype is designated for S. cardinalis. Morphological changes with growth in the two species are described in detail.     

<Emphasis Type="Italic">Phuphanochloa,</Emphasis> a new bamboo genus (<Emphasis Type="Italic">Poaceae</Emphasis>: <Emphasis Type="Italic">Bambusoideae</Emphasis>) from Thailand

Summary  A new monotypic bamboo genus Phuphanochloa (Poaceae: Bambusoideae) from north-eastern Thailand is described, together with a new species, P. speciosa.     

New species of the genus <Emphasis Type="Italic">Scolecostigmina</Emphasis> and revision of <Emphasis Type="Italic">Cercospora cryptomeriicola</Emphasis> on conifers

Scolecostigmina chibaensis on Pinus parviflora is described as a new species. Cercospora cryptomeriicola Sawada on Cryptomeria japonica is transferred to the genus Pseudocercospora, based on the morphological characteristics of the type specimen and newly collected specimens.     

On species composition of northern pacific genera <Emphasis Type="Italic">Eurycope</Emphasis> and <Emphasis Type="Italic">Baeonectes</Emphasis> and Redescription of <Emphasis Type="Italic">E. ochotensis</Emphasis> Kussakin, 1979 (Crustacea,Isopoda)

Two northwestern Pacific species of the munnopsid subfamily Eurycopinae, Eurycope pavlenkoi Gurjanova, 1933 and E. ochotensis Kussakin, 1979 are transferred to the other genus of the subfamily, Baeonectes Wilson, 1982, on the basis of the following characteristics: short truncated epipod of maxilliped, broad rostrum without distinct margins, absence of a distomedial lobe of the article 1 of antenna 1, mandible with broad, rounded molar and long condyle and pereonites 5–7 fused dorsomedially. Based on the mentioned characters E. pygmaea G.O. Sars, 1870, which was put into the genus Tytthocope Wilson & Hessler, 1981 is also suggested to be transferred into the genus Baeonectes. After the clarification of the taxonomical position of the species, the geographical range of the genus Baeonectes expanded. In the Sea of Japan the genus was registered for the first time.     

Transfers to <Emphasis Type="Italic">Simsia</Emphasis> and description of <Emphasis Type="Italic">Davilanthus</Emphasis>, a new genus of Asteraceae (Heliantheae)

Taxonomic changes are made to reflect a reassessment of morphology based on the results of molecular phylogenetic studies. A new genus, Davilanthus, is described to include six species that collectively form the sister group to Simsia, and includes the following species transferred from Viguiera: Davilanthus davilae, Davilanthus hidalgoanus, Davilanthus hypargyreus, Davilanthus huajuapanus, Davilanthus purpusii, and Davilanthus sericeus. Three species formerly placed in Viguiera ser. Grammatoglossae are transferred to Simsia: Simsia benziorum, Simsia ovata, and Simsia rhombifolia.     

Revised treatment of <Emphasis Type="Italic">Memecylon</Emphasis> sect. <Emphasis Type="Italic">Afzeliana</Emphasis> (<Emphasis Type="Italic">Melastomataceae: Olisbeoideae</Emphasis>), including three new species from Cameroon

Summary  Seven new names at species rank are proposed in Memecylon sect. Afzeliana Jacq.-Fél., a group of forest shrubs and small trees confined to Guineo-Congolian Africa. The group is centred in Cameroon, where 17 of the 20 species occur. A new flower type, the “star-flower” in Memecylon is revealed, and its taxonomic and ecological importance discussed. Three new, locally endemic species from the South West Province of Cameroon are described, mapped and illustrated: M. kupeanum R. D. Stone, Ghogue & Cheek, M. bakossiense R. D. Stone, Ghogue & Cheek, and M. rheophyticum R. D. Stone, Ghogue & Cheek. Two new names, M. accedens R. D. Stone, Ghogue & Cheek and M. hyleastrum R. D. Stone & Ghogue and one new combination, M. mamfeanum (Jacq.-Fél.) R. D. Stone, Ghogue & Cheek are provided at species level for three taxa originally proposed as varieties of M. afzelii G. Don. The taxon M. arcuatomarginatum var. simulans Jacq.-Fél. is also elevated to species status, as M. simulans (Jacq.-Fél.) R. D. Stone & Ghogue. Conservation assessments are provided for all the newly named taxa. A key is provided to the species of Memecylon sect. Afzeliana.     

Revision of <Emphasis Type="Italic">Trimmatothele</Emphasis> (Verrucariaceae), and description of <Emphasis Type="Italic">Oevstedalia</Emphasis> for <Emphasis Type="Italic">Trimmatothelopsis antarctica</Emphasis>, a new lichen genus with true ascoconidia

The type species of Trimmatothele is shown to differ from Verrucaria only by the multispored asci. Trimmatothele is consequently regarded as a younger synonym of Verrucaria, and the new combination Verrucaria perquisita proposed. The species is just known from Europe, where it is very rare on calcareous rocks and has a boreo-alpine distribution. Trimmatothelopsis antarctica is a very distinct lichen, not related with Verrucaria, and the new genus Oevstedalia is described to accommodate it. Oevstedalia is characterized by relatively pale perithecia with a hyphal wall, abundant pseudoparaphyses, sparse, thin, basally branched and anastomosed interascal filaments, an I− and K/I− centre, and very large, subcylindrical, entirely thin-walled, K/I+ blue asci containing in the living state 8 conidial balls filled with numerous ascoconidia. Oevstedalia might be related to the Epigloeaceae (family inc. sedis) and represents the first example of a lichenized ascomycete forming true ascoconidia. O. antarctica appears to be endemic in Antarctica, where it seems to be widespread and relatively common. No material is available for Trimmatothele umbellulariae and Lesdainea maritima, and no final conclusion can be given for the taxonomic status of these two species.     

A new species of <Emphasis Type="Italic">Penopus</Emphasis> (Teleostei: Ophidiidae) from the Ryukyu Trench,the West Pacific,with remarks on <Emphasis Type="Italic">Penopus microphthalmus</Emphasis>

The bathyal genus Penopus (Ophidiidae) is revised based on 23 specimens. One specimen from the Ryukyu Trench represents a new species, Penopus japonicus. The remaining 22 specimens were found on both sides of the Atlantic Ocean, and neither 28 meristic and morphometric characters nor several morphological characters show any differences between the two populations. This supports Séret (1988), who considered Penopus macdonaldi Goode and Bean 1896 a junior synonym of Penopus microphthalmus (Vaillant 1888). The new Japanese species can be separated from the Atlantic species by having fewer rays in the dorsal (117 vs. 135–158) and anal (89 vs. 106–122) fins, the squamation of the head restricted to the middle part of the preopercle versus the squamation covering the dorsum, preopercle and the opercle in part, a distinct spine behind the posterior nostril versus the spine hardly visible and 9 spines on the hind margin of the preopercle versus 4–7 spines.     

The Madagascan genus <Emphasis Type="Italic">Vaughania</Emphasis> is reduced to synonymy under <Emphasis Type="Italic">Indigofera</Emphasis> (<Emphasis Type="Italic">Leguminosae-Papilionoideae-Indigofereae</Emphasis>)

Summary  Eleven species comprising the Madagascan genus Vaughania are subsumed within the large pantropical genus Indigofera. Six new combinations are made; the remaining species were originally described in Indigofera.     

A new species of <Emphasis Type="Italic">Brasiliomyces</Emphasis> (Erysiphaceae) on <Emphasis Type="Italic">Dalbergia cultrata</Emphasis> var. <Emphasis Type="Italic">cultrata</Emphasis> from Thailand

A powdery mildew fungus on leaves of Dalbergia cultrata var. cultrata (Fabaceae) collected at the Queen Sirikit Botanical Garden in northern Thailand is proven to be a new species of the genus Brasiliomyces and is described as B. chiangmaiensis sp. nov. with light and SEM micrographs. Differences in known Brasiliomyces species are discussed, and a key to species of this genus is provided.     

A new species of <Emphasis Type="Italic">Macroptilium</Emphasis> (Benth.) Urb. (<Emphasis Type="Italic">Leguminosae</Emphasis>: <Emphasis Type="Italic">Papilionoideae</Emphasis>: <Emphasis Type="Italic">Phaseolinae</Emphasis>) from North-Eastern Brazil

Summary  A new species of Macroptilium sect. Microcochle (Benth.) J. A. Lackey is herein described from the states of Piauí and Bahia, Brazil. Macroptilium cochleatum is characterized by few-flowered inflorescences, calyx teeth longer than the tube, a tightly four-coiled keel, and linear, patent fruits. The discovery of this unique Macroptilium species, with its distally coiled keel, expands the diagnostic features of the genus. A key to the Brazilian species of sect. Microcochle is provided.     

<Emphasis Type="Italic">Camellia cattienensis</Emphasis>: a new species of <Emphasis Type="Italic">Camellia</Emphasis> (sect. <Emphasis Type="Italic">Archaecamellia</Emphasis>: Theaceae) from Vietnam

A new species of the genus Camellia L. (Theaceae, Theoideae) is described and illustrated under the name C. cattienensis. This species occurs in the rainforest vegetation of Lam Dong Province, Vietnam. A discussion of the morphological characters distinguishing this new species from related Camellia species is presented. Morphological evidence supports a transitional taxonomic placement in Camellia sect. Archaecamellia Sealy. This placement is justified by C. cattienensis exhibiting some morphological characteristics also found in sects Stereocarpus (Pierre) Sealy and Piquetia (Pierre) Sealy.     

Iranian <Emphasis Type="Italic">Trichogramma</Emphasis>: ITS2 DNA characterization and natural <Emphasis Type="Italic">Wolbachia</Emphasis> infection

Egg parasitoids of the genus Trichogramma (Hymenoptera: Trichogrammatidae) are important natural enemies of many lepidopterous pests in agricultural and forest areas. Because the use of indigenous Trichogramma populations/species can significantly increase the biological control efficiency, the characterization of endemic populations and precise species identification is important. In this study, Trichogramma wasps were collected from parasitized eggs of several lepidopteran pests in Northern and Central Iran. Seven Trichogramma species were identified based on the morphology and the nucleotide sequence, size and restriction profile (PCR-RFLP) of the internal transcribed spacer 2 (ITS2) region of the rDNA of T. brassicae Bezdenko, T. cacoeciae Marchal, T. embryophagum Hartig, T. evanescens Westwood, T. euproctidis Girault, T. pintoi Voegelé and T. tshumakovae Sorokina. This is the first report of T. euproctidis in Iran. Additionally, natural populations were surveyed for the prevalence of Wolbachia. Two populations of T. brassicae were found to be infected by a single Wolbachia strain which was identified by using a multi-locus sequencing approach.
