Biosystematic studies on the spittlebug genus Philaenus with the description of a new species

Populations of the genus Philaenus were collected during the last 12 years at several places in Greece ranging in altitude from sea level to 2000 m. Within some of these populations the species P. spumarius (Linnaeus, 1758), which is widely distributed in Greece, and the Mediterranean species P. signatus (Melichar, 1896) occurred together. These two species can be easily distinguished by the size of the adults, and more precisely by internal genital structures. Surprisingly, some mountainous populations of P. spumarius also contained a new species. Externally the new species closely resembled P. spumarius , but careful examination of the male genitalia provided clear identification characteristics. The new species comprised one bisexual common colour morph similar to populi of P. spumarius and P. signatus and two rare unisexual morphs which are lacking both in P. spumarius and P. signatus. The new species occurred only at altitudes above 1200 m on Eryngium spp. (Umbelliferae) between June and August.     

The Puccinia species of Berkheya (Asteraceae) with description of four new species from South Africa

Puccinia species (rust fungi, Pucciniales, formerly Uredinales) occurring on Berkheya (syn. Stobaea) of Asteraceae are critically evaluated. Puccinia berkheyicola, P. stobaeae var. stobaeae and P. stobaeae var. woodii are recognized as valid species and varieties, while P. berkheyae is relegated to a synonym of P. stobaeae var. stobaeae. Lectotypes are selected for P. stobaeae var. stobaeae and P. stobaeae var. woodii. P. clanwilliamensis, P. garstfonteinii and P. monsfontium are proposed as new species for three rust fungi previously assigned to P. stobaeae; P. berkheyaephila is described as new on B. bipinnatifida. A key to the accepted species is presented.     

Aeolid opisthobranch molluscs (Glaucidae) from the Indian Ocean and the south-west Pacific

Eight aeolid opisthobranch molluscs of the subfamilies Facelininae, Favorininae, and Herviellinae are reported from Tanzanian waters, and two species from Northwestern India. New records from Queensland, Australia greatly extend the range of two species reported from Tanzania. Phidiana militaris (Alder & Hancock) and P. indica (Bergh) are shown to be distinct and a species from New Zealand, originally identified as P. militaris , is shown to be new. P. bourailli (Risbec), previously reported only from New Caledonia, is described from Tanzania, as is a new species of Phidiana. Favorinus japonicus Baba is reported from Tanzania, the first published record outside Japan, a new species of Godiva is described from Tanzania and Queensland, and three new species of Sakuraeolis are described, one from India and two from Tanzania. A new species of Herviella is described from Tanzania.

A new distinctive species of pagurid hermit crab (Crustacea: Decapoda: Anomura) from Japan

A new species of pagurid hermit crab, Pagurus decimbranchiae, is described and illustrated based on 20 specimens collected from shallow waters of the Pacific coast of Japan ranging from Boso Peninsula to Tanegashima Island. It is quite distinctive in having the rudimentary arthrobranch on the third maxilliped represented by a single bud, however close morphological similarity is found between the new species and P. moluccensis Haig and Ball. Comparisons are also made among other species, including P. boriaustraliensis Morgan, P. sp. cf. boriaustraliensis sensu Rahayu and Komai (2000) and the members of the P. anachoretus group. The present generic assignment of the new species should be considered provisional, as more extensive study is needed to investigate phylogenetic relationships of the new species and the other species of Pagurus.

Description of three Pristionchus species (Nematoda: Diplogastridae) from Japan that form a cryptic species complex with the model organism P. pacificus

Three new species of Pristionchus (P. exspectatus, P. arcanus, and P. japonicus) are described from Japan. They are morphologically similar, with P. exspectatus and P. arcanus being almost indistinguishable from the model organism P. pacificus. Reproductive isolation, namely the inability to produce interfertile F1 hybrids, separates all species pairs in the species complex. Additionally, all three new species are distinguished from P. pacificus Sommer, Carta, Kim, and Sternberg, 1996 by having a gonochoristic instead of hermaphroditic mode of reproduction. In addition to its reproductive isolation, P. japonicus is distinct from other Pristionchus species by its arrangement of genital papillae. All species in the complex are separated from each other by molecular sequence divergence, as indicated by analysis of 27 nuclear protein-coding genes and unique sequences of the small subunit ribosomal RNA gene. The identification of a species complex that includes P. pacificus is invaluable for studies of population genetics, speciation, and macroevolution, particularly the evolution of hermaphroditism in the genus.     

Printed in Great Britain The genus Phyllhermannia (Acari: Cryptostigmata)

The genus Phyllhermannia Berlese, 1916 is redefined. Two main groups of species are postulated within the genus, each being further divided into two subgroups. Known species reviewed completely or in part are: P. dentata, P. bimaculata, P. mollis and P. pulcher . New distribution records are given for the New Zealand species P. foliata, P. forsteri, P. mollis, P. phyllophora and P. rubra , together with a distribution map of all species. Some biogeographical comments are included for the genus. P. africana Balogh, 1958 is redescribed and a new species, P. collofi sp.n., is established. A key to the species of the world is provided.

Description of a new species of Phylloscopus warbler from Vietnam and Laos

A new species of Phylloscopus warbler, which we name Phylloscopus calciatilis Limestone Leaf Warbler, is described from central and northern Vietnam and central and northern Laos; it probably also breeds in southernmost China. In morphology, the new species is very similar to Sulphur-breasted Warbler Phylloscopus ricketti , but it is smaller with a proportionately larger bill and rounder wing. Its song and calls are diagnostic. Based on mitochondrial and nuclear DNA, the new species is most closely related to P. ricketti and Yellow-vented Warbler Phylloscopus cantator , and it is inferred to be sister to the latter. The mitochondrial divergences between these three species are at the low end of the variation found in other species of Phylloscopus and Seicercus warblers, but greater than in other taxa generally treated as subspecies. Possible introgressive hybridization between the new species and P. ricketti is discussed, but more data are needed to establish whether it does occur and, if it does, to what extent. The new species appears to have a restricted breeding range in limestone karst environments, where it is locally common and therefore not under any immediate threat. In view of the recognition of the new species, all previous records of P. ricketti sensu lato need to be re-evaluated.     

Taxonomic studies in the genus Peristylus (Orchidaceae) in Thailand

A taxonomic review of the Thai species of the orchid genus Peristylus is presented. Seventeen species are recognised, five of them new to Thailand. Peristylus rigidus and P. phuwuaensis are endemic species, new to science, and the widespread P. maingayi and P. mannii have recently been newly recorded in the country. In addition, two further collections do not match any known Thai species, but very much resemble P. nematocaulon from the Himalayas and China. The present study will form the basis for the taxonomic account of Peristylus in the Flora of Thailand.
