A New Species

A new species of the genus Amaurobius C.L. Koch, 1837, Amaurobius pesarinii sp. n., from the Apennine Mountains (Italy) is described on the basis of both sexes. The male of A. pavesii Pesarini, 1991, previously unknown, is also described. Females of A. pavesii and both sexes of the similar A. scopolii Thorell, 1871 are re-described. Detailed description of morphological characters allow clear separation between these species and the closely related A. ferox (Walckenaer, 1820). Their phylogenetic relationships among the most common Italian Amaurobius species are discussed on the basis of molecular data (partial fragments of the genes COI, 16S and H3), together with their distribution across the Italian Peninsula. This is the first contribution to a multi-locus phylogenetic tree of European Amaurobius species. The synonymy of A. sciakyi Pesarini, 1991 with A. ruffoi Thaler, 1990 is proposed based on morphological characters.

A New Species

Abstract New molecular and morphological analyses of the relationships of 77 specimens of potamonautid freshwater crabs collected from all parts of Madagascar support the monophyly of the island’s freshwater crab fauna and verify most of the existing taxa. The phylogenetic tree identified several new lineages that represent four new genera and 10 new species, and found Foza Reed & Cumberlidge, 2006 to be paraphyletic. The present work is the first of a series of articles reporting on these discoveries that provide an improved understanding of the relationships between the endemic potamonautid species found on this tropical island. We describe a new species of Malagasya Cumberlidge & Sternberg, 2002 from a phytotelmic habitat in northeast Madagascar, and establish Agoragen. nov. to accommodate Thelphusa goudoti H. Milne Edwards, 1853. Both of these new taxa are recognized based on combinations of morphological characters and molecular data. The new species of Malagasya is distinguished from the other two species of this genus, which are illustrated here for comparative purposes. Agora goudotin. comb. is endemic to Madagascar, and is compared with and distinguished from the eight other genera of freshwater crabs occurring in that country.

A New Species

A new species, Entoloma coccineum, is described from Sichuan Province of China. It is characterized by brilliant red, small and slender basidiomata with deeply decurrent lamellae, and cuboid basidiospores 7–11 μm. The combination of these morphological characters is very distinctive among the known taxa of Entoloma, and the molecular data of the internal transcribed spacer (ITS) and the nuclear ribosomal large subunit (nrLSU) sequences also show it to be an independent taxon. In this paper, the new species is morphologically described and illustrated in detail, phenotypic and phylogenetic closely related taxa are compared, and a phylogenetic tree based on the nrLSU sequences is presented.

New species of Crella (Pytheas) Topsent, 1890 and Crellomima Rezvoi, 1925 (Crellidae, Poecilosclerida, Demospongiae) from Chilean shallow and Argentinean deep waters, with a synthesis on the known phylogenetic relationships of crellid sponges

Phylogenetic Affinities

Here, we describe four new species of Crellidae Dendy, 1922 and discuss characters and relationships from published molecular phylogenies including crellid sponges. New species proposed are Crella (Pytheas) chiloensis Fernandez, Gastaldi, Pardo & Hajdu, sp. nov., from southern Chile (15 m depth), C. (P.) desventuradae Fernandez, Gastaldi, Zapata-Hernández & Hajdu, sp. nov., from Desventuradas Archipelago (10–20 m depth), Crella (P.) santacruzae Fernandez, Gastaldi, Thompson & Hajdu, sp. nov., from deep waters off Argentina (750 m depth) and Crellomima sigmatifera Fernandez, Gastaldi & Hajdu, sp. nov., from the Chilean fjords region (ca. 20 m depth). These new species are set apart from each other and from known species mainly due to aspects of their spiculation. Chelae microscleres and acanthostyles supply characters that might be used to infer phylogenetic relationships and to verify the monophyly of Crella Gray, 1867 and Crellidae, which has seemingly been contradicted by preliminary molecular data available in the systematics’ literature. Our own interpretation of phylogenetic affinities, in the light of morphological characters from previous taxonomic studies, argues for a classification reassessment of materials (vouchers) included in these molecular phylogenies, especially in the case of Crella incrustans (Carter, 1885). We argue that currently available molecular phylogenetic outcomes for crellid sponges are not supportive of the polyphyly of Crella and Crellidae.

A New Species

Heimioporus sinensis, collected from tropical and subtropical areas of China, is introduced as a new species based on both morphological characters and molecular data. The species is characterized by the purplish red to deep magenta pileus, the reticulated stipe, the irregularly reticulate to reticulate-alveolate basidiospores 11.5–13.5 × 8–9.5 μm, and a trichodermal to intricately trichodermal pileipellis. Phylogenetic analyses based on the nuc 28S rDNA D1-D2 domains (28S) and the translation elongation factor 1-α gene (tef1-α) showed that H. sinensis is a distinct member of the genus Heimioporus in the subfamily Xerocomoideae.

Paris lihengiana (Melanthiaceae), a new species from Yunnan Province, China, is described and illustrated based on evidence from morphological characters and molecular phylogeny. It differs from other species of Paris in its pubescent stem, pedicel and abaxial leaf surface, as well as other characters. Molecular phylogenetic analysis of 33 taxa in Paris was conducted based on nuclear ribosomal ITS and six plastid markers. Paris lihengiana is supported as a new species by both morphological characters and molecular data.

A new species of the Gekko japonicus group is described from Khammouane Province, central Laos, based on morphological characters and molecular data. Morphologically, Gekko nadenensis sp. nov. is differentiated from the remaining congeners by a combination of the following characters: size moderate (SVL 61.0–77.1 mm); nares bordered with rostral; internasals absent; postmentals enlarged; interorbital scales between anterior corners of the eyes 28–30; dorsal tubercles absent; ventral scales between mental and cloacal slit 175–185; midbody scale rows 123–140; ventral scale rows 38–40; subdigital lamellae on first toes 13–15, on fourth toes 14–16; finger and toe webbing present at base; tubercles on dorsal surface of fore and hind limbs absent; precloacal pores six (3+3 or 5+1) in a discontinuous row in males, absent in the female; postcloacal tubercles 1 or 2; tubercles absent on dorsal surface of tail base; subcaudals distinctly enlarged; dorsal surface of body with greyish brown blotches. Molecular analyses demonstrated the new species is closely related to G. bonkowskii and G. thakhekensis, but separated from them by approximately 7% in genetic divergence as shown by a fragment of the mitochondrial ND2 gene.

A New Species

The identification of Auricularia species has previously relied on the examination of macroscopic features of mushroom samples collected in Thailand. These features may vary with age, light exposure, moisture and other factors, making such identification prone to error. This study uses morphological characteristics and molecular data to improve upon previous classifications of Auricularia species. Fruiting bodies collected during recent field excursions and previous collections from herbaria were examined and sequenced for two loci, viz. ITS and rpb2. Auricularia asiatica is described as a new species based on both morphological characteristics and molecular data, and is introduced with a full description, illustrations and colour photographs. Auricularia cornea and A. villosula are described as new records from Thailand. A combined ITS and rpb2 phylogenetic tree is provided, showing the placement of five Auricularia species found in Thailand.

A New Species

The taxonomy of the Allium saxatile group (sect. Oreiprason) has been studied recently upon morphological and molecular data. New specimens collected from the European part of Turkey near the Istranca Mountains and identified as ‘A. saxatile’ proved to be a new species confirmed by sequences of internal transcribed spacer (ITS) and two plastid DNA regions (rpl32–trnL and trnL–trnF) and supported by morphological characters. Allium urusakiorum, a new species from the A. saxatile group, is described here through living and herbarium specimens. It is the only species of the sect. Oreiprason in the country and seems to be an endemic species of the Turkish flora. Characteristics of the species include morphological description, identification key, molecular dataset, and karyotype (2n = 16).
