A new species of Cuacuba (Araneae,Theridiosomatidae) from Brazilian caves

ABSTRACT

A new species of the spider genus Cuacuba from Brazil, C. ribeira sp. nov. is described and illustrated based on eighty-six specimens collected from caves in the Vale do Ribeira region, in the states of São Paulo and Paraná. This species is recognized by the hook-shaped median apophysis on the male palp, and females by having invaginations on the sides of the median posterior edge of the epigynal plate. Cuacuba ribeira sp. nov. is the third species recorded for the genus, and like the other two, also comes from Brazilian caves.

Three new species of penicillium

Three new species of microfungi belonging to the genus Penicillium Link ex Fries are described and illustrated. All but one have been isolated from the atmosphere of las Palmas, capital city of the island of Gran Canaria (Canary Islands, Spain). They clearly differ from all species of the genus described so far and are, therefore, described and proposed as new species: Penicillium hispanicum sp. nov., Penicillium grancanariae sp. nov., and Penicillium palmensis sp. nov.     

The Electric Glass Knifefishes of the Eigenmannia trilineata species‐group (Gymnotiformes: Sternopygidae): monophyly and description of seven new species

Eigenmannia trilineata López and Castello, 1966 (Sternopygidae) was described from the Río de La Plata basin and subsequently cited from most South American river basins. Questions about the limits of this species raise the possibility of the occurrence of undescribed species misidentified as E. trilineata. Herein we propose the Eigenmannia trilineata species group for species that share the presence of the superior medial stripe on the flank. This group comprises: E igenmannia antonioi sp. nov. , from the Rio Anapu, Rio Amazonas basin; E igenmannia desantanai sp. nov. , from the Rio Cuiabá, Rio Paraguay basin; E igenmannia guairaca sp. nov. , from the Riacho Água do Ó, upper Rio Paraná basin; E igenmannia matintapereira sp. nov. , from the Rio Uneiuxi and Rio Urubaxi, Rio Negro basin; Eigenmannia microstoma (Reinhardt, 1852), from the Rio São Francisco basin; E igenmannia muirapinima sp. nov. , from small tributaries of the Rio Amazonas; E igenmannia pavulagem sp. nov. , from the tributaries of Rio Capim, Rio Guamá basin; E. trilineata, from the lower Rio Paraná basin and Río de La Plata basin; Eigenmannia vicentespelaea Triques, 1996, from São Vicente I and II caves, Rio Tocantins basin; and E igenmannia waiwai sp. nov. , from the Rio Trombetas basin. These species can be distinguished from each other by unique sets of meristics, morphometrics, osteological and colour pattern features. © 2015 The Linnean Society of London     

Some new species of Penicillium recovered from the atmosphere in Madrid and from other substrata

Six new species ofPenicillium Linkex Fries are described and illustrated. Four of them have been recovered from the atmosphere in Madrid, Spain, the other two species were isolated from must and from soil respectively. They clearly differ from all species of the genus described so far and are, therefore described and proposed as new taxa:Penicillium gerundense sp. nov.,Penicillium valentinum sp. nov.,Penicillium alicantinum sp. nov.,Penicillium malacaense sp. nov.,Penicillium tarraconense sp. nov., andPenicillium vasconiae sp. nov.     

Terrestrial isopods (Crustacea: Isopoda: Oniscidea) from Brazilian caves

To date, six species of terrestrial isopods were known from Brazilian caves, but only four could be classified as troglobites. This article deals with material of Oniscidea collected in many Brazilian karst caves in the states of Pará, Bahia, Minas Gerais, Mato Grosso do Sul, and São Paulo, and deposited in the collections of the Museu de Zoologia, Universidade de São Paulo, the Coleção de Carcinologia do Departamento de Zoologia, Universidade Federal do Rio Grande do Sul, and the collection of the Natural History Museum, Section of Zoology ‘La Specola’, Florence. Three new genera have been recognized: Spelunconiscus gen. nov. and Xangoniscus gen. nov. (Styloniscidae), and Leonardoscia gen. nov. (Philosciidae). Twenty‐two species have been identified, 11 of which in the families Styloniscidae, Philosciidae, Scleropactidae, Plathyartridae, Dubioniscidae, and Armadillidae are new to science: Leonardoscia hassalli sp. nov., Metaprosekia quadriocellata sp. nov. , Metaprosekia caupe sp. nov. , Amazoniscus leistikowi sp. nov. , Novamundoniscus altamiraensis sp. nov. , Trichorhina yiara sp. nov. , Trichorhina curupira sp. nov. , and Ctenorillo ferrarai sp. nov. from Pará; Xangoniscus aganju sp. nov. from Bahia; and Spelunconiscus castroi sp. nov. and Trichorhina anhanguera sp. nov. from Minas Gerais. Four new species in the families Styloniscidae ( Spelunconiscus castroi sp. nov. and Xangoniscus aganju sp. nov. ), Philosciidae ( Leonardoscia hassalli sp. nov. ), and Scleropactidae ( Amazoniscus leistikowi sp. nov. ) with highly troglomorphic traits can be considered as troglobitic, whereas all the remaining species are either troglophilic or accidentals. Brazilian caves are now under potential threat because of recent legislation, and the knowledge of the subterranean biodiversity of the country is thus of primary importance. © 2014 The Linnean Society of London     

Four new species of Penicillium isolated from the air

Four new species of Penicillium Link ex Fries are described and illustrated. All of them but one have been isolated from the atmosphere in Madrid, Spain. They clearly differ from all species of the genus described so far and are, therefore, described and proposed as new taxa: Penicillium aurantio-flammiferum sp. nov., Penicillium gallaicum sp. nov., Penicillium granatense sp. nov., and Penicillium ilerdanum sp. nov.     

New species of sap beetles (Coleoptera: Nitidulidae: Epuraeinae,Cybocephalinae) from the Baltic amber

A new genus, Baltoraea gen. nov., two new species of this genus, B. insignis sp. nov. and B. simillima sp. nov., and three other new species, Cybocephalus (Cybocephalus) balticus sp. nov., C. (C.) electricus sp. nov. and C. (C.) kerneggeri sp. nov. are described from the Late Eocene Baltic amber. The systematic position of the genus Baltoraea and presumable bionomics of the new sap beetles are discussed.     

Species delimitation in the Andean grasshopper genus Orotettix Ronderos & Carbonell (Orthoptera: Melanoplinae): an integrative approach combining morphological,molecular and biogeographical data

The reciprocal illumination nature of integrative taxonomy through hypothesis testing, corroboration and revision is a powerful tool for species delimitation as more than one source has to support the hypothesis of a new species. In this study, we applied an integrative taxonomy approach combining molecular and morphological data sets with distributional patterns to examine the level of differentiation between and within the grasshopper Orotettix species. Orotettix was described based on five valid species distributed in the Andes of Peru. In our study, initially a molecular‐based hypothesis was postulated and tested against morphological data and geographical patterns of distribution. Results from molecular and morphological analyses showed agreement among the species delimitation in Orotettix, and were also consistent with the geographical distribution. The analyses allowed us to delimit five new species for the genus ( O. lunatus sp. nov. , O . astreptos sp. nov. , O. colcaensis sp. nov. , O . paucartambensis sp. nov. and O . dichrous sp. nov. ) from the Eastern and Western Cordilleras of Peru. We also provide critical knowledge on the phylogenetic relationships and distribution of the genus and conduct a revision of Orotettix. © 2015 The Linnean Society of London     

New click beetles (Coleoptera: Elateridae) from the cretaceous of Russia and Kazakhstan

A new tribe, two new genera, and seven new species of click beetles are described: Pollostelaterini, trib. nov., Pollostelater baissensis, gen. et sp. nov. from the Lower Cretaceous of Transbaikalia (Baisa locality), five new species in the genus Cryptocoelus Dolin et Nel C. sinitshenkovae, sp. nov. (Romanovka locality), C. shcherbakovi, sp. nov., C. baissensis, sp. nov., C. lukashevichae, sp. nov., C. dolini, sp. nov. (all from Baisa locality), and Turonelater giganteus, gen. et sp. nov. from the Turonian of Southern Kazakhstan (Kzyl-Dzhar locality).     

<Emphasis Type="Italic">Pycnophyes dolichurus</Emphasis> sp. nov. and <Emphasis Type="Italic">P. aulacodes</Emphasis> sp. nov. (Kinorhyncha,Homalorhagida, Pycnophyidae), two new kinorhynchs from Spain with a reevaluation of homalorhagid taxonomic characters

Two new species of the kinorhynch genus Pycnophyes are described from the Atlantic Ocean, Northwest Spain, and the Mediterranean Sea, East of Spain, using differential interference contrast microscopy and scanning electron microscopy (SEM): Pycnophyes dolichurus sp. nov. and P. aulacodes sp. nov. Taxonomic characters from cuticular structures in homalorhagids are discussed and reevaluated. The longitudinal positions of cuticular structures along the trunk are furthermore defined, and the positional terminology is standardized. The distribution of the genus Pycnophyes in European waters is revised, revealing a poor knowledge of kinorhynch biogeography, probably due to incomplete sampling.     

Seven new species of Penicillium and a new variety of Penicillium novae-caledoniae Smith

Seven new species of Penicillium Link ex Fries and a new variety of Penicillium novae-caledoniae Smith are described and illustrated. Four of them have been recovered from the air in Madrid, Spain, one from beech leaves litter in a beech forest near Nancy, France, two from sandy soils in Madrid, and one from an andosol in the Spanish Province of Navarra. They clearly differ from all species of the genus described so far and are, therefore, described and proposed as new taxa: Penicillium turolense sp. nov., Penicillium murcianum sp. nov., Penicillium ovetense sp. nov., Penicillium asturianum sp. nov., Penicillium onobense sp. nov., Penicillium castellonense sp. nov., Penicillium aragonense sp. nov., and Penicillium novae-caledoniae Smith, var. album var. nov.     

South American electric knifefishes of the genus Archolaemus (Ostariophysi,Gymnotiformes): undetected diversity in a clade of rheophiles

Neotropical electric knifefishes of the family Sternopygidae previously considered to represent a single relatively geographically widespread and morphologically variable species, Archolaemus blax, were analysed and found to represent a complex of five species, four of which are new to science. A fifth undescribed species from the Rio São Francisco basin outside the previous known range of the genus was identified. Recognized species of Archolaemus are: A. blax, previously thought to occur in the Rio Araguari, Rio Branco, Rio Tapajós, Rio Tocantins, and Rio Xingu, but which instead proved to be endemic to the Rio Tocantins; Archolaemus ferreirai sp. nov. from the Rio Mucajaí and Rio Uraricoera in the north‐eastern portions of the Amazon basin; Archolaemus janeae sp. nov. of the Rio Xingu and the upper Rio Tapajós, both southern tributaries of the mainstream Amazon; Archolaemus luciae sp. nov. of the Rio Trombetas, Rio Jari, and Rio Tapajós basins of the eastern Amazon, and the independent Rio Araguari draining into the Atlantic Ocean north of the mouth of the Amazon; Archolaemus orientalis sp. nov. of the São Francisco basin in eastern Brazil; and Archolaemus santosi sp. nov. of the Rio Jamari in the south‐western portion of the Amazon basin. The phylogenetic placements of Archolaemus and the recently described genus Japigny relative to the other members of the Eigenmanninae are discussed. A series of synapomorphies for Archolaemus are proposed and a hypothesis of the relationships within that genus is advanced. Rheophily of all members of Archolaemus is discussed, with the genus found to be the most specious clade within the Gymnotiformes living primarily in high‐energy settings. The reported anterior projection of the dentary teeth in A. blax was found to be a consequence of postmortem displacement.     

Two new species of Caprella (Crustacea:Amphipoda:Caprellidea) collected from sandy bottoms in the Strait of Gibraltar

Two new species of the genus Caprella (Crustacea:Amphipoda:Caprellidea) are described based on specimens collected from the Strait of Gibraltar (Southern Spain and Northern Africa). Both species were found living in sandy bottoms. Caprella pseudorapax n. sp. is very close to the species C. rapax (Mayer, 1890) and C. lilliput (Krapp-Schickel & Ruffo, 1987). Caprella sabulensis n. sp. resembles C. cavediniae (Krapp-Schickel & Vader, 1998).     

Morphology and molecular phylogeny of coccoid green algae Coelastrella sensu lato (Scenedesmaceae,Sphaeropeales), including the description of three new species and two new varieties

The genus Coelastrella was established by Chodat (Bull. Soc. Bot. Geneve, 13 [1922] 66), and was characterized as being unicellular or in few‐celled aggregations with many longitudinal ribs on the cell wall. Many species of this genus showed strong ability to accumulate carotenoids and oils, so they have recently attracted much attention from researchers due to its potential applicability in the energy and food industries. In this study, a total of 23 strains of Coelastrella were sampled from China, and three new species and two new varieties were described: C. thermophila sp. nov., C. yingshanensis sp. nov., C. tenuitheca sp. nov., C. thermophila var. globulina var. nov., C. rubescens var. oocystiformis var. nov. Besides 18S rDNA and ITS2 sequences, we have newly sequenced the tufA gene marker for this taxon. Phylogenetic analysis combined with morphological studies revealed four morphotypes within the Coelastrella sensu lato clade, which contained the morphotype of original Coelastrella, original Scotiellopsis, Asterarcys, and morphotype of C. vacuolata and C. tenuitheca sp. nov. The relationships between morphological differences and phylogenic diversity based on different markers were discussed. Our results support that 18S rDNA was too conserved to be used a species‐specific or even a genus‐specific marker in this clade. The topology of tufA gene‐based phylogenetic tree had a better match with the morphological findings.     

Vacuolaria tropicalis,a new species of Chloromonad from Southern Brazil

Vacuolaria tropicalis sp. nov. is here described as a new species of Chloromonadophyceae, observed in material collected during the summer of 1968–1969 from an artificial pool behind the greenhouses in the São Paulo Botanical Garden in the city of São Paulo. It is distinguished from the three previously described species of the genus chiefly by cell shape and by colour and localisation of the chromatophores.     

Species delimitation in annual killifishes from the Brazilian Caatinga,the Hypsolebias flavicaudatus complex (Cyprinodontiformes: Rivulidae): implications for taxonomy and conservation

The organisms investigated are members of the Hypsolebias flavicaudatus species complex; a clade of morphologically similar annual killifishes endemic to the semi-arid savannah of north-eastern Brazil in the São Francisco River basin, which is a tropical area under intensive process of habitat loss. A taxonomic revision was conducted combining two different approaches for species delimitation – a tree-based approach using mt-DNA (cytochrome b) and a character-based approach using morphological variation (colour patterns, fin morphology, meristic and morphometric data). Nine species are recognised, of which five are new species: H. flagellatus (Costa), H. flavicaudatus (Costa & Brasil), H. gilbertobrasili sp. nov., H. guanambi (Costa & Amorim), H. janaubensis (Costa), H. nitens sp. nov., H. pterophyllus sp. nov., H. radiseriatus sp. nov. and H. sertanejo sp. nov. On the basis of 17 years of field studies, preliminary conservation status assessments indicate that two species are highly threatened with extinction, at least one is endangered and another is vulnerable, whereas the others are not endangered. This result deeply contrasts with a previous assessment 10 years ago, when the whole H. flavicaudatus complex was considered as a single species of no conservation concern. Discrepancies in the assessment of conservation among closely related species living in similar habitats are a consequence of heterogeneous human occupation and disproportionate recent development throughout the São Francisco River basin.
