A New Species

Schistidium foraminis-martini is described as a new species from the Austrian and Swiss Alps. The taxon is characterized by a warm brown coloration, ovate, concave and muticous leaves with rounded apices, ellipsoid capsules, constricted at mouth, the presence of stomata and a reduced, truncate peristome. Based on sequences of the ITS region the new species is phylogenetically rather isolated, exhibiting the closest relationship to S. agassizii which shares the muticous leaves but differs in having narrowly lingulate-lanceolate, almost flat leaves, cyathiform capsules and a perfect peristome. Schistidium foraminis-martini grows on moist calcareous rocks in the alpine and nival belt.

A New Species

Macroinvertebrate samples collected during spring-summer 2013 in high mountain rivers of the Ordesa and Monte Perdido National Park (Pyrenees) contained several Hydraena species (Coleoptera: Hydraenidae) where we found two genera of suctorian ciliates as epibionts: Tokophrya and Discophrya. The individuals of the genus Tokophrya probably belong to species Tokophrya stenostyla, being the first time that this species is observed attached on arthropods. Suctorians of the genus Discophrya were identified as a new species called Discophrya ordesae sp. n. The presence and abundance of epibionts was discussed in the frame of the biological and ecological characteristics of the species of Hydraena where they were found.

Alcolapia Grahami

A new species of Gyrodactylus von Nordmann, 1832 is described from the gills of Alcolapia grahami, a tilapian fish endemic to Lake Magadi. This alkaline soda lake in the Rift Valley in Kenya is an extreme environment with pH as high as 11, temperatures up to 42 °C, and diurnal fluctuation between hyperoxia and virtual anoxia. Nevertheless, gyrodactylid monogeneans able to survive these hostile conditions were detected from the gills the Magadi tilapia. The worms were studied using light microscopy, isolated sclerites observed using scanning electron microscopy, and molecular techniques used to genetically characterize the specimens. The gyrodactylid was described as Gyrodactylus magadiensis n. sp. and could be distinguished from other Gyrodactylus species infecting African cichlid fish based on the comparatively long and narrow hamuli, a ventral bar with small rounded anterolateral processes and a tongue-shaped posterior membrane, and marginal hooks with slender sickles which are angled forward, a trapezoid to square toe, rounded heel, a long bridge prior to reaching marginal sickle shaft, and a long lateral edge of the toe. The species is also distinct from all other Gyrodactylus taxa based on the ITS region of rDNA (ITS1–5.8s–ITS2), strongly supporting the designation of a new species. These findings represent the second record of Gyrodactylus from Kenya, with the description of G. magadiensis bringing the total number of Gyrodactylus species described from African cichlids to 18.

Berteroa physocarpa, a new species from the subalpine-alpine zone (1600−2200 m) of northwest Anatolia, is described and illustrated. It shares with the other species of Berteroa 2n=16 and morphologically is readily distinguished from them by having distinctly inflated fruit with glabrous valves. Sequences of nuclear ribosomal transcribed spacer (ITS) region were used to determine the relationship of Berteroa species using maximum likelihood methods. The phylogenetic results confirmed the recently established systematic history of Berteroa and also supported the recognition of this new species.

A New Species

High-mountain regions are known to harbour considerable biodiversity, although it is not all well known. The terrestrial fauna of the world’s largest mountain range, the Himalayas, has been moderately well studied, but this is not the case with the limnic fauna, and especially molluscs. During intensive malacozoological field surveys conducted over the past 20 years, the bivalve family Sphaeriidae has been studied in Nepal along an elevational gradient from 100 to 4010 m above sea level (a.s.l.). Here we describe a new species of Sphaeriidae, Pisidium alexeii, sp. nov., based on comprehensive molecular phylogenetics, anatomy and shell morphology. The species can be clearly distinguished from all other sphaeriid species occurring in Nepal. A molecular phylogeny based on mitochondrial and nuclear data inferred the oriental biogeographical affinity of the new species. The species is ecologically restricted and only occurs at a few sites between 1010 and 1700 m a.s.l. A review and updated checklist of the sphaeriid fauna of Nepal is provided and biodiversity and biogeographical patterns are discussed.

Conocybe punjabensis sp. nov., a species belonging to the saprobic family Bolbitaceae, is illustrated and described from Pakistan based on morphology and molecular evidence. The species can be distinguished on the basis of medium-sized fruiting bodies, a pileus with a dark brown central disc, a fibrillose stipe, forked lamellae near pileus margin, ellipsoid angular basidiospores with an apical germ pore, cheilocystidia and pleurocystidia varying from catenulate, lecythiform to clavate, and lecythiform caulocystidia. Molecular phylogenetic analysis of the nuclear ribosomal ITS region also supports the recognition of this new species in Conocybe. Detailed descriptions, photographs, illustrations and comparison with allied taxa are given.

A New Species

Lactarius sect. Deliciosi is a group of ectomycorrhizal mushrooms showing high host specificity with trees of Pinaceae and more rarely Fagales. A new species of this section, L. guangdongensis, is described from South China. This new species has the smallest basidiocarps (pileus 1–3 cm) in the section. The pure orange basidiocarps with faint greenish discoloration are similar to those of Abies-associated L. abieticola and L. laeticolor and Pinus-associated L. vividus. The subdistant lamellae and absence of pleuromacrocystidia can be used as valid characters for this species. It grows with Chinese national protected plant Pinus kwangtungensis and might be one of the very few species that form symbiosis with five-needle pines. Phylogenetic analyses of the ITS region and glyceraldehyde-3-phosphate dehydrogenase gene (gpd) show that L. guangdongensis clearly diversified from its relatives and look-alikes and probably represents an early diverging lineage in the section. Molecular and morphological characters provided in this study will be useful for in situ and ex situ conservation of P. kwangtungensis in the future.

A new species, Nupela eremica sp. nov. is described from a high mountain lake located in the Eastern Range of Colombian Andes. The new taxon was studied from sediment and epiphyton samples and under light and scanning electron microscope. Comparison with morphologically similar taxa is showed. N. giluwensis, N. carolina, N. gomphosphenioides, N. encyonopsis, N. incerta, N. neglecta, N. tenuicephala, and N. exilissima show morphometric values overlapping those of Nupela eremica sp. nov. The combination of valve size and outline is unique and justifies the erection of this new species.

Peucedanum huangshanense, a new species discovered in Anhui, China, is illustrated and described. Detailed morphological comparisons have showed that it is similar to P. praeruptorum but differs from the latter by having larger compound umbels (5–14 cm across), rays up to 25, and long-ovoid mericarps with lateral ribs narrowly winged. To explore the phylogenetic position of this species, nuclear ribosomal DNA internal transcribed spacer (ITS) region was sequenced for P. huangshanense and P. praeruptorum collected in different places. The morphological and molecular evidences support the hypothesis that P. huangshanense is a new distinct species.

Sanghuangporus vitexicola (Hymenochaetales) is described as a new species based on collections made from Pingtung County, tropical South Taiwan. All studied basidiocarps grew on living trunks of Vitex negundo. This new species is characterized by having perennial, pileate basidiocarps; pore surface yellowish brown, pores 6–8 per mm; context 0.7–1.5 cm thick; setae ventricose to subulate, dark brown, 17–30 × 5–8 μm; basidiospores broadly ellipsoid, brownish, smooth, 4.2–4.8 × 3.2–3.7 μm, with 0.2–0.5 μm thick walls. Maximum likelihood and Bayesian inference phylogenies inferred from the internal transcribed spacer (ITS) region of rDNA indicated that six strains of Sanghuangporus viexicola formed a monophyletic group which is sister to S. zonatus. An identification key to known species of Sanghuangporus is provided.
