New ostracodes of the families Loxoconchidae and Trachyleberididae from the Barremian-Albian of southwestern Crimea

New species of ostracodes of the families Loxoconchidae Sars, 1925 and Trachyleberididae Sylvester-Bradley, 1948 are described from the Upper Barremian-Albian sediments of southwestern Crimea. Loxoella? macrofoveata sp. nov. and L.? microfoveata sp. nov. belong to the family Loxoconchidae. Exophthal-mocythere posteropilosa sp. nov. belongs to the family Trachyleberididae.     

Pliocene ostracods of Southwestern Europe

This paper analyzes the lithostratigraphic features and ostracod associations of the Pliocene deposits located in the western sector of the Guadalquivir basin (SW Spain). A regressive cycle is defined by the vertical distribution of five main facies (FA-1 to FA-5), which were deposited in upper bathyal to fluvial palaeoenvironments. The broad palaeontological record is utilized to draw a general outline of the food chain in each palaeoenvironment. A comparison with the Pliocene ostracod distribution of southeastern Spain, southwestern France and Portugal permits to define a common ostracod biozonation for southwestern Europe during this period. Four main marine biozones are distinguished: (a): Pontocythere elongata biozone (infralittoral); (b): Costa edwardsii biozone (shallow circalittoral); (c): Bosquetina carinella biozone (deep circalittoral); and (d): Henryhowella asperrima biozone (upper bathyal). Freshwater, brackish and lower bathyal/abyssal species are very scarce in this area during this period.

Brief notes on the habitat and life-history of some of the species are given.Present address: Dept. of Zoology, The University, Glasgow     

A new genus and species in the mite family Eupodidae (Acari,Eupodoidea) from Crimea

A new genus Pseudoeupodes Khaustov, gen. n. and new species Pseudoeupodes porosus sp. n. are described from moss in Crimea. The taxonomy of the Eupodidae and some other families and genera of Eupodoidea is reviewed. The genus Turanopenthalodes Barilo, 1988 is transferred from Penthalodidae to Penthaleidae. The family Cocceupodidae Jesionowska, 2010 and the genus Filieupodes Jesionowska, 2010 are considered as junior synonyms of Eupodidae Koch, 1842 and Cocceupodes Thor, 1934, respectively. A key to genera of the family Eupodidae is provided.     

中国西南亚高山带乳菇属小红乳菇亚属的2个新种（英文）

描述了乳菇属的2个新种:高山毛脚乳菇Lactarius alpinihirtipes和假脆乳菇L.pseudofragilis。该2种生于中国西南亚高山带的针叶林和栎林下,其盖表皮为菌丝球囊型,孢子具网纹。高山毛脚乳菇与原初描述自中国的毛脚乳菇L.hirtipes为姊妹种。假脆乳菇以暗褐色的子实体近似于北美的L.fragilis和欧洲的L.serifluus及L.subumbonatus。文中提供了该2新种的外观和显微特征描述及与相近种的形态对比和ITS序列。

Vertebrae of sea snakes from the Eocene of the Crimea

A sea snake vertebra from the Middle Eocene (Kuma Horizon) of the vicinity of the town of Bakhchisarai (Crimea) is referred to Palaeophis nessovi Averianov, 1997, which was previously recorded in the Middle and Upper Eocene of northern and western Kazakhstan. P. udovichenkoi Averianov, 1997 described from the Crimea based on the material from the Prolom locality (Bartonian-Priabonian?) is a junior subjective synonym of P. nessovi. A vertebra from the Belaya Skala locality (Middle Eocene, outskirts of the town of Belogorsk) is determined as Palaeophis sp.     

Endemism and ecological islands: the ostracods from Jamaican bromeliads

1. The inhabitants of ecological islands, such as the phytolemata of bromeliad plants, provide an opportunity to examine the genetic patterns resulting from island radiations and draw inferences about modes of speciation.
2. Allozyme electrophoresis, as well as mitochondrial DNA and morphological analyses, were employed to delimit species boundaries and assess the population genetic structure of the ostracods from bromeliads on the island of Jamaica.
3. Nine species from the genus Elpidium were both sexually reproducing and endemic to the island. The other commonly encountered ostracod genus, Candonopsis , was represented by at least two sexually reproducing species.
4. Most Elpidium species showed very restricted distributions, low heterozygosity, and marked gene pool fragmentation, suggesting that population bottlenecks have occurred frequently. Whether founder events played a causal role in the diversification of these ostracods remains uncertain, but bromeliad habitats seem to be a source of high biodiversity, and may represent an ideal setting for extensive allopatric speciation.     

New larger foraminifers from the Eocene of the Crimea (Ukraine) and Mangyshlak (Western Kazakhstan)

Two new species of Nummulites and one subspecies of Orbitoclypeus from the Eocene of the Crimean Mountains and Mangyshlak Peninsula are described in detail. Nummulites alexisi sp. nov. and Orbitoclypeus munieri major subsp. nov. come from the Upper Ypresian, while Nummulites ninikae sp. nov. is from the Lower-Middle Lutetian. The phylogenetic position of new taxa is discussed.

Palaeozoic roots of the sigilliid ostracods

Podocopine ostracods rapidly increased in species diversity after the Palaeozoic, and 32 out of the 36 podocopine families are extant (Whatley et al., 1993), but the phyletic origins are known for only a few. The Sigilliacea are unique in having a long and detailed fossil record. The Sigilliidae known from the recent and Mesozoic faunas differ from others ostracods in having large adductor muscle scars with many spots, a character typical rather to Palaeozoic forms. Paleozoic Microcheilinellidae were morphologically close to the sigilliids, but details of their hingement and carapace margin structures were unknown until now.Silicified specimens of Microcheilinella mendelgrammi, new species, from the Early Carboniferous of southern China and Microcheilinella mandelstami, from the Middle Devonian of north-western Poland show merodont hingement and narrow calcified inner lamella. This makes their relationship to the Mesozoic, Tertiary, and recent sigilliids Saipanetta, Cardobairdia, Sigillium, and Kasella likely. The sigilliid lineage was thus established already in the Devonian.Tubulibairdia, with adont hingement and tubulous shell wall, and Microcheilinella s. s., with merodont hingement and no tubules, are distinct genera in different families.
