The leucosiid crab Orientotlos iishibai Sakai, 1980 was described from one female collected off western Japan and had never been reported since. The species is now recorded from southwestern Taiwan for the first time, and is redescribed and figured at length. Although Sakai argued that Orientotlos Sakai, 1980, is closely related to Oreophorus Rüppell, 1830 and Atlantotlos Doflein, 1904, the genus is actually morphologically most similar to Merocryptus A. Milne-Edwards, 1873. The two genera, however, still differ markedly in a number of key carapace and cheliped characters.

Two rare xanthid crabs of the genusEuryxanthopsGarth & Kim, 1983 were collected from Donggang fish port in southwestern Taiwan.EuryxanthopsflexidentatusGarth & Kim, 1983, is recorded from Taiwan for the first time; this species was originally described from the Philippines on the basis of a single male. The taxonomy of a second species,E. orientalis(Sakai, 1939), is also treated and the variations in carapace form, in anterolateral margin armature, and in colour pattern are discussed. The known range of this species is also extended to southern Taiwan.

Members of the family Coralliidae, known as precious corals, are ecologically and economically important deep-sea or-ganisms. However, these organisms are currently threatened by commercial harvesting. In order to create and implementeffective conservative strategies, taxonomic knowledge of conservative targets is necessary, but unfortunately the taxon-omy of precious corals in this family is still ambiguous. This study provides a review of 15 Coralliidae species from thenorthern West Pacific region and a key to species identification. In addition, descriptions of two new species, Coralliumcarusrubrum n. sp. and C. taiwanicum n. sp., as well as a redescription of C. sulcatum Kishinouye, 1903 are included.Corallium carusrubrum n. sp. is distributed on seamounts off northeastern Taiwan. The autozooids of C. carusrubrum n.sp. are retractile and each can be fully withdrawn into the cortex thereby causing a mound on the surface which is shortand cylindrical rather than typically hemispherical; additionally, there are no long spindles in their tentacles. Coralliumtaiwanicum n. sp. is distributed in an area off southwestern Taiwan. It has special unique 8-radiates with an oval shapeand large projections. Corallium sulcatum is distributed from an area off southwestern Taiwan to western Japan. It hasbeen harvested and traded for decades, but there were no illustrations in its original description, hence a redescription of this species is provided.

This study describes two new species of earthworms belonging to the genus Drawida (Oligochaeta: Moniligastridae) from southwestern Taiwan. They are Drawida alishanensis sp. nov. and Drawida fenqihuensis sp. nov. The two species were found at elevations of 1407–1661 m in the Alishan area, Chiayi County. DNA barcodes from type specimens of the new species are reported. This is the first time that new species of Drawida are discovered from the island of Taiwan. In addition, Drawida keikiensis Kobayashi, 1938 from Korea is found to be synonymous with Drawida syringa Chen, 1933 from central China. The synonymy of Drawida glabella Chen, 1938 with Drawida barwelli (Beddard, 1886) is rejected.

The deep sea squat lobster, Sternostylus hendersoni (Alcock & Anderson, 1899a), is reported for the first time from Taiwan, also representing the first record of the genus from the area. Two specimens of S. hendersoni were collected near a cold-seep area off southwestern Taiwan. Both specimens are females and have similar morphology but different body coloration, with one specimen being reddish orange and the other is pinkish orange. The differences in coloration are illustrated.

The Brown Anole (Anolis sagrei) has become an invasive species in some parts of the Americas and in some localities in the Pacific region. In Taiwan A. sagrei was recorded for the first time in 2000 in Santzepu, southwestern Taiwan, and was subsequently recorded in Chisintang, eastern Taiwan, during 2006. For future monitoring and research, we describe the known distribution of A. sagrei in Taiwan by plotting GPS coordinates of localities where A. sagrei was observed during surveys (conducted on an ad hoc basis since this species was first discovered in Taiwan) or where specimens have been collected on GIS User Community aerial photographs that were divided into 100 x 100-m grids. We recorded this invasive lizard in southwestern Taiwan in an area spanning approximately 237 ha and in an approximately 8-ha area in eastern Taiwan. Since A. sagrei is easily spread by human activities, and because not all areas could be thoroughly surveyed, we conclude that the current actual distribution of A. sagrei in Taiwan is probably more extensive than shown. We believe that the eradication of A. sagrei in Taiwan through removal is unrealistic, and propose that ongoing efforts should focus on managing this species.

The monogenean Benedenia epinepheli (Yamaguti, 1937) Meserve, 1938 is redescribed and reported for the first time from the fins, eyes, and body surface of cultured marine fishes of Japan. Because of close similarity in the general morphology of the reproductive system and median sclerites, comparable morphometrics, and the presence of a flap slightly left of the common genital aperture, Benedeniella congeri Yamaguti, 1958 (= Neobenedeniella congeri (Yamaguti, 1958); Benedenia congeri (Yamaguti, 1958)) and Benedenia sp. of Tsutsumi and Ito, 1965 are synonimized with this species. Twelve new hosts are presented, bringing the total number of known hosts to 25 (11 Tetraodontiformes, 9 Perciformes, 3 Scorpaeniformes, 1 Pleuronectiformes, and 1 Anguilliformes). The ability of B. epinepheli to cause death of cultured fishes during heavy infection, and its low host specificity, ubiquitous distribution in western Japan, and the high susceptibility of marine aquarium fishes are indicative of the parasite's great potential to become a disease problem.

Two new species of elongate unpatterned moray eels related to Gymnothorax prolatus are described. Gymnothorax pseudoprolatus sp. nov. is described from one specimen collected off southwestern Taiwan and Gymnothorax vietnamensis sp. nov. is described from seven specimens collected off central Vietnam. Both differ from other species in the group in the number of vertebrae, position of anus, and dentition. Gymnothorax pseudomelanosomatus Loh et al., 2015 is reported from southern Taiwan for the first time; it was previously known from the type series collected off the northeastern tip of Taiwan. Gymnothorax angusticauda (Weber & de Beaufort 1916) is reported for the first time in Taiwan and the Philippines.

Although the presence of annulate lamellae was noted in many cell types, including the rat spermatogenic cells, this structure was never reported in the Sertoli cells of any rodent species. The present report is based on a part of our project on the effect of torsion of the spermatic cord to the contralateral testis. This paper describes for the first time, the fine structural details of the annulate lamellae in the Sertoli cells of damaged testis from guinea pigs.One side of the spermatic cord of each of six Hartly strain adult guinea pigs was surgically twisted (540°) under pentobarbital anesthesia (1). Four months after induction of torsion, animals were sacrificed, testes were excised and processed for the light and electron microscopic investigations. In the damaged testis, the majority of seminiferous tubule contained a layer of Sertoli cells with occasional spermatogonia (Fig. 1). Nuclei of these Sertoli cells were highly pleomorphic and contained small chromatinic clumps adjacent to the inner aspect of the nuclear envelope (Fig. 2).

A new Zeiss TEM with an imaging Omega filter is a fully digitized, side-entry, 120 kV TEM/STEM instrument for materials science. The machine possesses an Omega magnetic imaging energy filter (see Fig. 1) placed between the third and fourth projector lens. Lanio designed the filter and a prototype was built at the Fritz-Haber-Institut in Berlin, Germany. The imaging magnetic filter allows energy-filtered images or diffraction patterns to be recorded without scanning using efficient area detection. The energy dispersion at the exit slit (Fig. 1) results in ∼ 1.5 μm/eV which allows imaging with energy windows of ≤ 10 eV. The smallest probe size of the microscope is 1.6 nm and the Koehler illumination system is used for the first time in a TEM. Serial recording of EELS spectra with a resolution < 1 eV is possible. The digital control allows X,Y,Z coordinates and tilt settings to be stored and later recalled.

Microstructural studies by transmission electron microscopy (TEM) of diamond films grown by chemical vapor deposition (CVD) usually involve tedious specimen preparation. This process has been avoided with a technique that is described in this paper. For the first time, thick as-grown diamond films have been examined directly in a conventional TEM without thinning. With this technique, the important microstructures near the growth surface have been characterized. An as-grown diamond film was fractured on a plane containing the growth direction. It took about 5 min to prepare a sample. For TEM examination, the film was tilted about 30-45° (see Fig. 1). Microstructures of the diamond grains on the top edge of the growth face can be characterized directly by transmitted electron bright-field (BF) and dark-field (DF) images and diffraction patterns.
