AbstractMale and female adults of Cowichania interstitialis n. gen., n. sp. are described, and Cowichaniinae n. subfam. is proposed for members of this genus and species. Adults of the new species are autapomorphic among Hydryphantidae in having an entire, uniformly sclerotized dorsal shield, the dorsoglandularia displaced laterally, the genital field located well posteriorly on the idiosoma, and unique sclerotized plates surrounding the coxal plates laterally and posteriorly, and are unusual in having slightly stalked genital acetabula and sexually dimorphic chaetotaxy on the tibiae of the pedipalps. Provisional remarks on phylogeny and higher classification of Hydryphantidae are also presented.

Victoriopisa bantenensis sp. nov. has not been previously reported and also the first record of the genus in Indonesian waters. It was collected from soft-bottom subtidal sediment in Banten Bay, West Java, Indonesia and is one of two Victoriopisa which has a notch on the anteroventral margin of the head. Victoriopisa bantenensis is characterized by the absence of eyes, the lateral cephalic lobes elongate and the absence of excavation on the gnathopod 2 propodus palm. Male and female of Victoriopisa bantenensis sp. nov shows sexually dimorphic characters on gnathopods 2. Male gnathopod 2 propodus palm without excavation while female with one excavation. Previously, 13 species of Victoriopisa has been described, and this one is the 14 species of the genus.

A new species Oecetis McLachlan, O. psammophila sp. nov., is described from the Sandhills ecoregion of South Carolina. Illustrations of male and female genitalia and wing photographs are provided. Following the classification of Chen (1993), O. psammophila belongs to the O. parva Species-group of the subgenus Pseudosetodes Ulmer. Adult specimens were taken at ultraviolet lights near or immediately adjacent to impounded streams or spring-fed wetlands. The larva remains unknown, but other Nearctic members of the O. parva Species-group inhabit lentic habitats.

Abstract Farrell, E. D., Hüssy, K., Coad, J. O., Clausen, L. W., and Clarke, M. W. 2012. Oocyte development and maturity classification of boarfish (Capros aper) in the Northeast Atlantic. – ICES Journal of Marine Science, 69: 498–507. This study presents the first detailed investigation of the oocyte development and maturity classification of boarfish, Capros aper, which has recently become the target of an industrial fishery in the Northeast Atlantic. A total of 2014 boarfish were collected from January to December 2010. Mature male and female boarfish were sexually dimorphic and could be readily identified based on external characteristics. A comprehensive maturity scale was developed, which indicated that the length at 50% maturity for males and females was 9.7 cm total length. Female boarfish were observed to spawn in Irish waters in June and July. Once spawning ceased the remaining mature oocytes were resorbed. Preliminary analysis of reproductive strategy indicates that the boarfish is likely an asynchronous batch spawner with indeterminate fecundity.

AbstractLarvae, deutonymphs, and male and female adults of Platyhydracarus juliani sp.nov., and adults of P. parvipalpis sp.nov., are described from rheocrenes and small streams in western North America. The genus Platyhydracarus gen.nov. is proposed and diagnosed, based primarily upon the presence of genital acetabula both in the gonopore and on acetabular plates flanking the gonopore, and of a group of thickened setae anterior to the gonopore, in male adults. Possible relationships between Platyhydracarus and other Athienemanniidae are discussed, and a new key to the genera of Athienemanniinae is presented.

Abstract—We describe and illustrate Paepalanthus fabianeae, a new species of Eriocaulaceae from the central portion of the Espinhaço Range in Minas Gerais, Brazil. Previous phylogenetic evidence based on analyses of nuclear (ITS and ETS) and plastid (trnL-trnF and psba-trnH) sequences revealed P. fabianeae as belonging to a strongly supported and morphologically coherent clade containing five other species, all of them microendemic, restricted to the Espinhaço range. Due to the infrageneric classification of Paepalanthus being highly artificial, we preferred not assigning P. fabianeae to any infrageneric group. Paepalanthus fabianeae is known from two populations growing in campos rupestres (highland rocky fields) in the meridional Espinhaço Range. The species is characterized by pseudodichotomously branched stems, small, linear, recurved, and reflexed leaves, urceolate capitula, and bifid stigmas. Illustrations, photos, the phylogenetic position, and a detailed description, as well as comments on habitat, morphology, and affinities with similar species are provided. The restricted area of occurrence allied with threats to the quality of the habitat, mainly due to quartzite mining, justifies the preliminary classification of the new species in the Critically Endangered (CR) category using the guidelines and criteria of the IUCN Red List.

Three New Species

Resuming published and own data, a revision of classification of Chaetognatha is presented. The family Sagittidae Claus & Grobben, 1905 is given a rank of subclass, Sagittiones, characterised, in particular, by the presence of two pairs of sac-like gelatinous structures or two pairs of fins. Besides the order Aphragmophora Tokioka, 1965, it contains the new order Biphragmosagittiformes ord. nov., which is a unique group of Chaetognatha with an unusual combination of morphological characters: the transverse muscles present in both the trunk and the tail sections of the body; the seminal vesicles simple, without internal complex compartments; the presence of two pairs of lateral fins. The only family assigned to the new order, Biphragmosagittidae fam. nov., contains two genera. Diagnoses of the two new genera, Biphragmosagitta gen. nov. (type species B. tarasovi sp. nov. and B. angusticephala sp. nov.) and Biphragmofastigata gen. nov. (type species B. fastigata sp. nov.), detailed descriptions and pictures of the three new species are presented.

Neomuscina Townsend includes 41 species distributed throughout the Nearctic and Neotropical Regions. Although the genus has a large number of species, it has been ignored and its taxonomy is confusing and has many flaws. In this work we analyzed the following species recorded for Brazil: Neomuscina atincta Snyder, N. atincticosta Snyder, N. capalta Snyder, N. currani Snyder, N. douradensis Lopes & Khouri, N. goianensis Lopes & Khouri, N. inflexa (Stein), N. instabilis Snyder, N. mediana Snyder, N. mimosa Lopes & Khouri, N. neosimilis Snyder, N. nigricosta Snyder, N. paramediana Lopes & Khouri, N. pictipennis pictipennis (Bigot), N. ponti Lopes & Khouri, N. sanespra Snyder, N. schadei Snyder, N. similata Snyder, N. stabilis (Stein), N. transporta Snyder, N. vitoriae Lopes & Khouri and N. zosteris (Shannon & Del Ponte). Neomuscina nigricosta and N. transporta are new distribution records for Brazil. Three new species are described: Neomuscina anajeensis sp. nov. from Anagé (Bahia), Neomuscina maculata sp. nov. from Botelhos (Minas Gerais) and Neomuscina snyderi sp. nov. from Mata de São João (Bahia). An identification key based on the morphological characters of both male and female is provided. Species distributions are discussed and updated, and the number of species now recorded for Brazil is 29.

A new toad, Rhinella cerradensis, is described, including its tadpole and the advertisement call. The new species occupies Cerrado habitats in the Brazilian states of Piauí, Bahia, Goiás, Minas Gerais, and Distrito Federal. The species is characterized by its large size; absence of tibial glands; well developed cranial crests; short hands; sexually dimorphic coloration; and by the absence of a spiracle tube of the tadpole. The new species is included in the Rhinella marina group by the presence of a jagged suture formed by the articulation between the pterygoid medial ramus and the parasphenoid alae, as well as other shared morphological features. Morphological characters and statistical analyses inferred by morphometric feature suggest the existence of two subgroups of species within R. marina group. However, taxonomic rearrangements are not made here and await phylogenetic analysis.
