Abstract—A new species of Acianthera, A. lueri, is described and illustrated based on material collected in the Amazon region of Peru. The combination of the glabrous ovary, 3-lobed lip, and long-tailed petals distinguish A. lueri from similar A. lanceana. The new taxon is placed within the key to identification of species reported from the Peruvian Amazon region.

A New Species

Bazzania amadoi is a new species described and illustrated here based on material collected during a study of the bryophyte flora in the Brazilian Amazon Mountains, Monte Roraima National Park, Roraima State, Brazil. Bazzania is the largest genus of Lepidoziaceae,with ca. 30 species recognized in South America. A combination of leaves slightly bifid and recurved to the ventral side, underleaves imbricate and connate with the leaves on only one side, and vittae absent with only a region of larger leaf cells in the mid-lower portion of the leaves (vitta-like), distinguishes B. amadoi from the similar B. gracilis. The new taxon is placed within the key for the identification of species from the Brazilian Amazon domain, and represents an addition to the rich endemic flora of the Brazilian Amazon mountains of the Guiana Highlands. A detailed illustration of the new species is included, and also its informal conservation assessment.

A New Species

A new orchid species in Stelis is described and illustrated. It was discovered in semi-deciduous montane forest in Southwestern Ecuador. The new species is named Stelis rostriformis. Information about its distribution, habitat, phenology, and conservation status is provided. The new taxon is a member of Crocodeilanthe, a group that has previously been considered as a different genus or as a subgenus of Pleurothallis, but the available evidence indicates that it turns out to be non-monophyletic. The new species is compared with other morphologically similar, such as S. batillacea, S. cyathiflora, S. galeata and S. gargantua. Additionally, Stelis sagittata is proposed as a new name for Pleurothallis jamesonii since the combination of it in Stelis proved be illegitimate because the earlier existence of Stelis jamesonii.

New Distribution

The orchid flora of Myanmar is highly diverse but as yet poorly known in the continental Asia, which is largely a result of periods of past instability and political isolation of the country. Also the remoteness of many orchid-rich areas and the difficulties of investigation in rugged terrain have also played a role (Ormerod & Kumar, 2003; Kurzweil & Lwin, 2014). According to recent estimates about 800 orchid species are distributed in Myanmar (Kurzweil & Lwin, 2014), which were probably underestimated. Many new distribution records and new species have been published in the last few years (Ormerod, 2002, 2006, 2012; Ormerod & Kumar, 2003, 2008; Ormerod & Wood, 2010; Nyunt, 2006; Kurzweil et al., 2010; Kurzweil & Lwin, 2012a,b; Tanaka et al. 2011).

Insight Into

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.

Basal Structure

Abstract. A very distinctive new deep-photic coccolithophore is described from the NE Indian Ocean. The new species is trimorphic with: 200–300 body coccoliths bearing low spines attached by narrow stems to a basal narrow-rimmed placolith structure; up to 18 circum-flagellar coccoliths with tall sail-like spines; and up to 22 coccoliths with moderately elevated spines occurring both around the circum-flagellar coccoliths and antapically. These features make the coccolithophore unique and require placement in a new species and genus. The basal structure, however, shows similarities to a recently recognized group of narrow-rimmed placoliths. Hence, the new coccolithophore provides some support for this grouping as a significant addition to our understanding of coccolithophore biodiversity, and potentially an explanation for a set of anomalous molecular genetic results. In addition the new taxon provides further evidence that the deep-photic coccolithophore community is more diverse than has been assumed.

Freshwater Diatom

During a survey of the freshwater diatom flora of the sub-Antarctic region (Iles Kerguelen and Iles Crozet) in the southern Indian Ocean, an unknown Cyclotella taxon was observed that was formerly identified as the presumed cosmopolitan C. meneghinana. Detailed morphological analysis based on light and scanning electron microscopical observations and comparison with several similar Cyclotella taxa worldwide justified the description of this unknown taxon as a new species: Cyclotella deceusteriana sp. nov. The new taxon is characterized by the presence of marginal fultoportulae on every costa, hyaline furrows between the raised marginal parts on which the striae are located, 2, occasionally 1, 3 or 4 central fultoportulae and an entirely flat, smooth, relatively small central area. The new species is described and compared with other Cyclotella taxa. Notes on its distribution and ecology are added.
