A worldwide survey of cercosporoid ascomycete species on hosts of the genus Diospyros (persimmon) with key to the species based on characters in vivo is provided. Special emphasis is placed on species of the genus Pseudocercospora, which are in part also phylogenetically analysed, using a multilocus approach. Species of the latter genus proved to be very diverse, with a remarkable degree of cryptic speciation. Seven new species are described (Pseudocercospora diospyri-japonicae, P. diospyriphila, P. ershadii, P. kakiicola, P. kobayashiana, and P. tesselata), and two new names are introduced [P. kakiigena (≡ Cylindrosporium kaki, non Pseudocercospora kaki), and Zasmidium diospyri-hispidae (≡ Passalora diospyri, non Zasmidium diospyri)]. Six taxa are lectotypified (Cercospora atra, C. diospyri, C. diospyri var. ferruginea, C. flexuosa, C. fuliginosa, C. kaki), and Pseudocercospora kaki is epitypified.

The morphology, infraciliature and silverline system of two marine peritrichous ciliates, Zoothamnium xuianum n. sp. and Z. paraentzii Song, 1991, collected from a shrimp-hatching plant in northern China, were investigated using both in vivo and silver impregnation methods. The new species is recognized by the following characters: colony alternatively branched, zooids in vivo about 45 × 30 μm with single-layered peristomial lip; contractile vacuole apically located; macronucleus band-like and transversely positioned; more than 50 striations from peristomial area to aboral trochal band, about 14 from aboral trochal band to scopula; three equally long kineties in peniculus 3 parallel to each other. Based on both the Qingdao population and the original description, an improved diagnosis for Z. paraentzii is suggested: marine Zoothamnium with irregularly dichotomously branched stalk; zooid 50–80 × 25–45 μm in vivo with single-layered peristomial lip; contractile vacuole apically positioned; macronucleus C-shaped, transversely orientated; number of silverlines between anterior end and aboral trochal band about 75–83, between aboral trochal band and scopula, 28–33; inner row of peniculus 3 displaced from the other two and converges with peniculus 1 at aboral end.

Species Specific

Seven new species of terrestrial Enchytraeidae (Oligochaeta) are described from soils of the southern Brazilian Atlantic rain forest. They were found in the framework of the German-Brazilian project SOLOBIOMA, which studied rain forest recovery. Specimens were investigated in vivo and as stained whole mounts. Three species belong to a new genus, named Xetadrilus. Xetadrilus is similar to Guaranidrilus Č ernosvitov, 1937 and Tupidrilus Righi, 1974; it differs in the absence of lateral chaetae from segment VIII on and in peculiar structures of the prostomium: ganglia, inner papillae, and a frontal epithelial recess. Further peculiarities are small body size, absence of oesophageal appendages, and a variable pattern of pharyngeal glands. The three species are named X. maacki, X. aphanus, and X. fabryi. Three further nominal species are transferred to Xetadrilus: Marionina pituca Righi, 1974, Marionina righiana Xie & Rota, 2001, and Stercutus ugandensis Bell, 1954. The other four new species belong to Guaranidrilus, the species-richest genus at the sampling sites. They are named G. andreolii, G. marquesi, G. cingulatus, and G. hoeferi. All species have elongate transverse epidermal gland cells, three pairs of post-pharyngeal ganglia, and a dorsal vesicle in the nephridial postseptale. These traits may be included in the genus diagnosis. In all species described here, most of the species-specific taxonomic traits are found in non-reproductive structures, which means that specimens of all age groups can be identified to the species level, juveniles included.

First Time

Recently, the rich coral communities of the so called roche du large biocoenose of the Gulf of St Eufemia (southern Tyrrhenian Sea) between 90 and 130 m deep, have been described thanks to remotely operated vehicle (ROV) imaging. This preliminary survey evidenced the massive presence of a well-diversified sponge community living among the coral colonies. This work aims at giving an ecological overview of some of the dominant species of this environment, together with a taxonomic part including the description of new species: Topsentia calabrisellae sp. nov. and Haliclona (Soestella) fimbriata sp. nov. The silted, rocky outcrops of the Gulf of St Eufemia facilitate the settling mainly of massive sponges with erect habit which may also avoid sedimentation by growing on the coral colonies. On the other hand, the site Capo Vaticano, located at the southern boundary of the gulf, characterized by rocky boulders exposed to strong currents and completely devoid of corals, is inhabited by a poor megabenthic community, dominated by patches of massive sponges, such as Topsentia vaceleti, a species of recent description whose aspect in the field was still unknown. In the entire investigated area 19 species have been photographed (often for the first time in vivo), collected and identified, but the real sponge diversity is certainly under-estimated due to the difficulty of collecting all the sighted specimens through the ROV grabber. Similarly to the coral component, sponges also respond to the same environmental constraints by growing in heterogeneous patches or by showing different morphologies mainly associated with current and sedimentation conditions.

In this paper we report and describe material of Halichondriidae sampled at 11 different stations in the Brazilian northeastern coast. Halichondria (Halichondria) marianae sp. nov. is a massively encrusting sponge, with firm texture, soft, fleshy, but compact and compressible. Color in vivo is dark green, becoming grayish or brown after fixation in ethanol; the spicules are smooth oxeas. Amorphinopsis atlantica from the Northeastern Brazil is thickly encrusting to massively, also with firm texture, color in vivo is usually yellow to dark green and both distributed in different regions, brownish after fixation in ethanol; the spicules are smooth oxeas and styles. A taxonomic study of these samples is given, including description and illustrations.

Very few studies exist on the description of protozoan ciliates from industrially contaminated sites. In this study, we report a description of a novel hypotrich ciliate isolated from water samples collected from an industrially contaminated outlet in Onsan, Ulsan, South Korea. The oxytrichid ciliate, Histriculus tolerans n. sp., was investigated using live observation and protargol impregnation. The morphology, morphogenesis, and molecular phylogeny inferred from small-subunit (SSU) rRNA gene sequences were studied. The new species is mainly characterized by a cell size of about 70 × 40 μm in vivo, two elongate ellipsoidal macronuclear nodules and one or two micronuclei, adoral zone of about 51% of body length with 32 membranelles on average, about 34 cirri in the right and 24 cirri in the left marginal row, 18 frontoventral transverse cirri, six dorsal kineties including two dorsomarginal rows, and dorsal kinety 1 with 26 bristles. Morphogenesis is similar to that of the type species, i.e., Histriculus histrio, except that oral primordium does not contribute to anlage II of the proter. Phylogenetic analyses, based on small-subunit rRNA gene sequences, consistently place the new species within the family Oxytrichidae, clustering with H. histrio.

The morphology, infraciliature and silverline system of a new marine ciliate, Frontonia lynni n. sp., isolated from a sandy beach at Qingdao, China, was investigated using live observation and silver staining methods. The new species is recognized by the combination of the following characters: body about 100–210 x 70–150 µm in vivo, elliptical in outline; dorsoventrally flattened (3:1); one large contractile vacuole equatorially located, right of median; 71–83 somatic kineties and three vestibular kineties; small oral cavity with peniculi 1 and 2 each having four ciliary rows and peniculus 3 possesses five gradually shortened rows.

We present a morphometric study comparing three Apoamphisiella species from Brazil. A. jurubatiba and A. tihanyiensis from Cabi nas Lagoon (Maca Rio de Janeiro), and A. foissneri sp. n. from Limoeiro River (Al m Para ba Minas Gerais). This new species was approximately 150 x 70 m in vivo, and was characterized by having two postperistomial cirri, two contractile vacuoles, and no cortical granules. In contrast, both A. jurubatiba and A. tihanyiensis had cortical granules and a single contractile vacuole. Furthermore, A. jurubatiba had three posterior frontal cirri and its right marginal cirral row started in the dorsal surface, whereas A. tihanyiensis had two posterior frontal cirri. Moreover, the dorsal ciliature pattern was also different among the three species.
