Description of the larva of Potamophilops cinereus (Blanchard) from Southeastern Brazil (Coleoptera, Elmidae, Larainae)

Larvae of Potamophilops cinereus (Blanchard, 1841) from Brazil, Sao Paulo, Ribeirao Grande (Fazenda Intervales, Rio Carmo) are described for the first time and illustrated. The larvae were found associated with adults. The larva of P. cinereus is most similar to larvae of species of the Mexican and Central American genera Disersus Sharp and Hispaniolara Brown, but can be easily distinguished chiefly by the head being not visible when seen from above, due to being concealed by the anterior projection of the pronotum. Comparisons of the three genera are presented. Photographs of the adult habitus of P. cinereus are also furnished. A key to the larvae of the genera of Larainae of Brazil is included.

A new species of Cnodalomyia Hull, 1962 (Diptera, Asilidae, Asilinae) from Brazil

The robber fly genus Cnodalomyia Hull, 1962 is a monotypic member of the Asilinae. The type species, C. obtusa Hull, is endemic to Itatiaia, State of Rio de Janeiro, Brazil. A new species, Cnodalomyia catarinensis sp. nov. from southern states of Brazil (Santa Catarina, Parana and Sao Paulo) is herein described and illustrated. Both species are restricted to highland areas of the Atlantic Forest. An identification key to the species is also presented.

Revision of the Neotropical robber fly genus Cnodalomyia Hull (Diptera, Asilidae, Asilinae) with description of two new species from Brazil

The genus Cnodalomyia includes only two Brazilian species: C. obtusa Hull, 1962 and C. catarinensis Lamas and Mellinger, 2008. Studying material deposited in the Museu de Zoologia da Universidade de Sao Paulo (MZUSP), the authors found a long series of unidentified specimens of the genus, some of which are specimens of C. obtusa labelled with the same data as the type series as well as other specimens from different localities, representing an enlargement of the known geographic records of the species. This material, together with the types of C. catarinensis, enables this revision. A redescription of the genus and of its type species, C. obtusa, including descriptions and illustrations of its spermathecae and egg, until now never described, the description and illustration of two new species (C. artigasi sp. nov. and C. papaveroi sp. nov.), the diagnosis and egg description of C. catarinensis and an identification key to all included species are presented herein.

Description of a new species of Calliostoma (Gastropoda, Calliostomatidae) from Southeastern Brazil

Calliostoma tupinamba is a new species from Southeastern Brazil, ranging from southern Rio de Janeiro to northern Sao Paulo, and found only on coastal islands, on rocks and sessile invertebrates at 3 to 5 meters of depth. Shell and soft part morphology is described here in detail. Calliostoma tupinamba is mainly characterized by a depressed trochoid shell; eight slightly convex whorls; a sharply suprasutural carina starting on the third whorl and forming a peripheral rounded keel; and a whitish, funnel-shaped and deep umbilicus, measuring about 5%-10% of maximum shell width. Calliostoma tupinamba resembles C. bullisi Clench & Turner, 1960 in shape, but differs from it in being taller and wider, having a smaller umbilicus and lacking a strong and large innermost spiral cord at its base. Finally, an identification key of Brazilian Calliostoma species is presented.

A revision of Evaniscus (Hymenoptera, Evaniidae) using ontology-based semantic phenotype annotation

The Neotropical evaniid genus Evaniscus Szepligeti currently includes six species. Two new species are described, Evaniscus lansdownei Mullins, sp. n. from Colombia and Brazil and E. rafaeli Kawada, sp. n. from Brazil. Evaniscus sulcigenis Roman, syn. n., is synonymized under E. rufithorax Enderlein. An identification key to species of Evaniscus is provided. Thirty-five parsimony informative morphological characters are analyzed for six ingroup and four outgroup taxa. A topology resulting in a monophyletic Evaniscus is presented with E. tibialis and E. rafaeli as sister to the remaining Evaniscus species. The Hymenoptera Anatomy Ontology and other relevant biomedical ontologies are employed to create semantic phenotype statements in Entity-Quality (EQ) format for species descriptions. This approach is an early effort to formalize species descriptions and to make descriptive data available to other domains.

Germination and seedling morphology of four South American Smilax (Smilacaceae)

Species of Smilax,, also known as greenbrier, are widely distributed in Brazil and their commercial trades are carried out by the extractivism of native species. We the aim to provide information about the germination and development of seedlings in four Smilax species, different experiments were developed under controlled conditions. We evaluated two germination treatments: temperature (30 degrees C and 20-30 degrees C) and light (presence/absence), and for few cases the tetrazolium treatment was applied. A different treatment response was observed among the studied species. Light had a significant influence in S. brasiliensis, with the highest germination rates at 20-30 C in dark conditions. S. campestris showed significant differences among temperature treatments, but not to light; while S. cissoides showed high germination rates (66-78%), independently of treatment. However, S. polyantha had low germination rates (19-24%). After one year, the expanded leaves showed different characteristics among the studied species. Leaves of S. brasiliensis were ovate, coriaceous, three main veins and prickle-like structures only on the midrib on abaxial face. S. campestris leaves were oblong, coriaceous and prickle-like structures were located at the leaf midrib and margin. S. cissoides had ovate-elliptic, membranaceous leaves, with three main veins with prickle-like structures on the abaxial face. S. polyantha leaves showed ovate-elliptic. coriaceous leaves, with three main veins, translucent secondary veins and no prickle-like structures. A seedling identification key was elaborated based on morphological characteristics. Rev. Biol. Trop. 60 (1): 495-504. Epub 2012 March 01.

Six new species of Paraleia Tonnoir (Diptera, Mycetophilidae): amphinotic elements at the northern range of the Andes

Paraleia was originally described by Tonnoir for P. fulvescens, known from Australia. More recently, eleven Neotropical species were added to the genus-nine of which are from Chile and southern Argentina, one from Bolivia, and one from Peru. This distribution pattern is typical of many mycetophilid genera. Six new Neotropical species of Paraleia from the Andean Colombia and Ecuador are herein described. Male terminalia of P. bolivari sp. n., P. denticulata sp. n., P. fumosa sp. n., and P. tonnoiri sp. n., as well as female terminalia of P. bolivari sp. n., P. denticulata sp. n., P. fumosa sp. n., P. nidorosa sp. n., P. sharkeyi sp. n., and Paraleia sp. are illustrated. High-resolution photos of wings for all species are presented. An identification key for world species of Paraleia is provided.

New species of Pseudanos Winterbottom, 1980 (Characiformes: Anostomidae), with notes on the taxonomy of P. gracilis and P. trimaculatus

A new species of Pseudanos (Characiformes, Anostomidae) is described from the Rio Negro in Brazil, and the Rio Casiquiare and Rio Atabapo, in Venezuela. Specimens of the new species were previously mistakenly identified as Pseudanos gracilis. The new species is diagnosed by having three branchiostegal rays (vs. four in P. gracilis and most specimens of P. winterbottomi), dark transversal bars on dorsum absent (vs. present in P. trimaculatus), dark spots present on the center of each body scale, forming conspicuous, straight dark lines (vs. dark spots absent in P. gracilis and in some specimens of P. trimaculatus), four midlateral dark blotches on body (vs. usually two, sometimes three or four in P. trimaculatus, or body lacking midlateral blotches and presenting instead a broad midlateral stripe in P. winterbottomi), angle of dorsal and ventralmost radii of body scales between 40 degrees and 90 degrees (vs. angle between 110 degrees and 180 degrees in P. gracilis and P. trimaculatus), and cranial fontanel opened along its entire length (vs. cranial fontanel partially closed in P. trimaculatus). Type specimens and extensive additional material of Pseudanos gracilis and P. trimaculatus were examined and comments on the taxonomy of both species are provided. Pseudanos irinae is herein considered a junior synonym of P. trimaculatus. In addition, an updated key to identification of valid species of Pseudanos is presented.

Two New Species of Stenophragma Skuse from Western Australia (Diptera, Mycetophilidae, Sciophilinae)

Stenophragma Skuse was originally described for S. meridianum (Skuse), from Australia. Since then seventeen species have been added to the genus-from Brazil, Ecuador, Peru, Bolivia, Paraguay, Chile, Argentina, and Canada. We add two new species to the genus Stenophragma-S. bickeli n.sp. and S. collessi n.sp.-from Western Australia. An identification key for the Australian species of Stenophragma is provided. Comments are made about possible relationships among these new species and the remaining Australasian species of the genus. OLIVEIRA, SARAH SIQUEIRA, AND DALTON DE SOUZA AMORIM. 2012. Two new species of Stenophragma Skuse from Western Australia (Diptera, Mycetophilidae, Sciophilinae). Records of the Australian Museum 64(2): 149-158.

A new species of Anchoviella Fowler, 1911 (Clupeiformes: Engraulidae) from the Amazon basin, Brazil

Anchoviella juruasanga is described from the drainages of rios Negro, Madeira, Tapajós, Trombetas, Tocantins, and Jari, in the Amazon basin, Brazil. The new species is distinguished from its congeners by having a short upper jaw, with its posterior tip extending between the verticals through anterior and posterior margins of the pupil (vs. posterior tip of upper jaw extending beyond the vertical through posterior margin of the pupil). Anchoviella juruasanga is also distinct from other strictly freshwater Amazonian species of the genus by the distance from tip of snout to posterior end of upper jaw between 8 and 11% in standard length (vs. 14% or more in A. alleni, A. carrikeri, A. guianensis, and A. jamesi). The anal-fin origin slightly posterior to or at the vertical through the base of the last dorsal-fin ray further distinguishes the new species from A. alleni (anal-fin origin posterior to the vertical through the last anal-fin ray by at least 14% of head length) and A. jamesi (anal-fin origin anterior to the vertical through the last anal-fin ray). An identification key for the Amazonian species of Anchoviella, including marine and estuarine species known to occur in the lower portion of the basin, is presented.
