AbstractThe Anatolian Platform, which was a part of the Gondwanan Platform, is mainly characterized by carbonate-dominated deposits ranging in age from Devonian to Permian. The biostratigraphy and systematics of a late Asselian–early Sakmarian fusulinid fauna from the Anatolian Platform including Eastern and Central Taurides have been investigated in three sections: Özbek Hill, Eskibey and Bademli. Twenty-four fusulinid taxa, belonging to twelve genera, were determined in a single fusulinid zone dated as late Asselian–early Sakmarian. Early–middle Asselian fusulinid faunas have not been observed in any of the measured sections throughout the Anatolian Platform. This indicates that lower to middle Asselian deposits are represented by an interval characterized by quartz sandstone overlying upper Gzhelian strata. Five new species (Pseudochusenella anatoliana, Pseudofusulinoides altineri, Pseudofusulinoides convexus, Pseudofusulinoides subglobosus and Pseudofusulinoides vachardi) are described in this study. The Early Permian fusulinid fauna correlates very well with the fauna of other sections in the Palaeotethyan realm (Southern Alps, Central Asia, Southern China and Japan).

AbstractThe myxozoan genus Unicapsula Davis, 1924 (Myxosporea: Multivalvulida: Trilosporidae) is characterized as having one functional polar capsule (PC) and two rudimentary PCs in a three-valved myxospore. The plasmodia of Unicapsula spp. grow either in the myofibres or in the gills, oesophageal walls and urinary organs of marine fish. Few studies have investigated the taxonomy of Unicapsula spp. including the type species Unicapsula muscularis. Accordingly, the taxonomy of the genus was explored in the present study by using 15 new isolates of seven Unicapsula spp. (U. muscularis, U. galeata, U. andersenae, U. pyramidata, U. pflugfelderi, and two new species) that had formed pseudocysts in the trunk myofibres of commercial fish collected in southern China and Japan from November 2015 to January 2019. Two new species Unicapsula trigona n. sp., and Unicapsula motomurai n. sp. exhibited unique myxospore morphologies (semi-triangular and spherical myxospores, respectively) and 18S and 28S rDNA sequences that were distinct from those of the other Unicapsula spp. Phylogenetic analysis of the 18S and 28S rDNA sequences confirmed the monophyletic status of Unicapsula.

The Elachistidae material collected during the joint Soviet-Finnish entomological expeditions to the Altai mountains, Baikal region and Tianshan mountains of the previous USSR is listed. Previous literature dealing with the Elachistidae in Central Asia is reviewed. A total of 40 species are dealt with, including descriptions of five new species: Stephensia jalmarella sp. n. (Altai), Elachista baikalica sp. n. (Baikal), E. talgarella sp. n. (southern Kazakhstan), E. esmeralda sp. n. (southern Kazakhstan) and E. filicornella sp. n. (southern Kazakhstan). The previously unknown females of E. bimaculata Parenti, 1981 and Biselachista zonulae Sruoga, 1992 are described.

Abstract The late Paleozoic temnospondyl Sclerocephalus formed an aquatic top predator in various central European lakes of the late Carboniferous and early Permian. Despite hundreds of specimens spanning a wide range of sizes, knowledge of the endocranium (braincase and palatoquadrate) remained very insufficient in Sclerocephalus and other stereospondylomorphs because even large skulls had unossified endocrania. A new specimen from a stratigraphically ancient deposit at St. Wendel in southwestern Germany is recognized as representing a new taxon, S. concordiae new species, and reveals a completely ossified endocranium. The sphenethmoid was completely ossified from the basisphenoid to the anterior ethmoid region, co-ossified with the parasphenoid, and the basipterygoid joint was fully established. The pterygoid bears a slender, S-shaped epipterygoid, which formed a robust pillar lateral to the braincase. The massive stapes was firmly sutured to the parasphenoid. In the temnospondyl endocranium, character evolution involved various changes in the epipterygoid region, which evolved distinct morphologies in each of the major clades.

The genus Paraboea Ridl. (Gesneriaceae) is revised. It is found in Bangladesh, Bhutan, Burma, Cambodia, southern China, India (Assam), Indonesia (Sumatra, Java, Borneo, Sulawesi), Laos, Malaysia (Peninsular and Borneo), Philippines, Thailand and Vietnam, mostly from limestone habitats. Eighty-nine species and five varieties are recognised. Four new species and one new variety are described: Paraboea apiensis Z.R.Xu, Paraboea argentea Z.R.Xu, Paraboea graniticola Z.R.Xu, Paraboea paraprimuloides Z.R.Xu and Paraboea harroviana var. ovata Z.R.Xu. In addition two taxa are highlighted as possible new species but are not described here due to insufficient material. The treatment includes one new combination for a species, Paraboea harroviana (Craib) Z.R.Xu, one new combination for a variety, Paraboea schefferi var. ambigua (C.B.Clarke) Z.R.Xu, one new status for a variety, Paraboea rufescens var. tomentosa (Barnett) Z.R.Xu, and one new name, Paraboea primuloides Z.R.Xu. Fifty-one line drawings are included. A key is presented and all taxa are described. Preliminary conservation assessments are given.

Grammothele and Theleporus have a shallow pore surface, which makes them morphologically close to corticioid fungi. However, from a phylogenetic perspective, they are polyphyletic genera within the core polyporoid clade of the Polyporales. Eight specimens with a shallow pore surface from Hainan, southern China, were morphologically and phylogenetically studied. Among them, one was determined as Grammothele denticulata, four were identified as Theleporus membranaceus, and three are described as Grammothele hainanensis. G. hainanensis is characterized by the annual and resupinate basidiocarps with poroid to irpicoid hymenophore, a dimitic hyphal system with clamped generative hyphae and weakly dextrinoid skeletal hyphae, the presence of cystidioles, hyphal pegs and dendrohyphidia, and cylindrical, hyaline and thin-walled basidiospores. It is closely related to G. quercina in phylogeny. Morphologically, G. quercina differs in producing perennial basidiocarps with cream to pale greyish and larger pores. The morphological differences among the new species and other species were analyzed.

Until the evolution of paper, which is dated traditionally in A.D. 105, the majority of Chinese documents were probably written on boards or narrow strips of wood or bamboo; the use of silk was reserved for the preparation of de luxe copies of certain works, either for sacred or for profane purposes. However, it was only quite recently that actual examples of wooden documents from China were first brought to the attention of the scholastic world, as a result of two series of expedit ions to central Asia and northwestern China. First, Sir Aurel Stein's expeditions, at the be ginning of the century, brought back fragments of inscribed wood from the sites of Tun-huang; thi s was subsequently examined and the results published, by Chinese scholars such as Wang Kuo-wei, an European scholars such as Chavannes and Maspero. Secondly, the expeditions led by Sven Hedin s ome thirty years later found similar material in larger quantities, from the more easterly sites of Chü-yen (Edsen-gol). These texts were published by a number of scholars, beginning with L ao Kan,who was working in China in the extremely difficult conditions of the 1940s.1940s.Shortly afterwards, Japanese scholars were able to turn their attention to this material whose content, l ike thatof the strips from Tun-huang, was almost exclusively concerned with the civil and militar y administration of Han imperial officials, between about 100 B.C.and A.D. 100. In the early 1960 s Professor Mori Shikazo led a series of seminar meetings to study the material from Chii-yen, wh ich the present writer was fortunate and privileged to attend. The results of such meetings were published atthe time in a number of Japanese periodicals, and constituted a valuable contribution to the studyof the wooden material from China known to exist at that time.
