A revision of the genus Lycomorphon (Coleoptera: Lycidae)

The Neotropical genus Lycomorphon Pic, 1922 is revised. Eleven species are classified in the genus, six of them are redescribed, five species (Lycomorphon brasiliense sp. n., L. amazonicum sp. n., L. bimaculatum sp. n. L. bolivianum sp. n., L. fulvohumeralis sp. n.) are proposed as new to science. Lycomorphon elongaticolle v. diversicolle Pic, 1926 is raised to species status, and Idiopteron irregularis is transferred to the genus Lycomorphon. The new subgenus Spinolycus sg. n. is proposed within Lycomorphon.

Generic classification for the Gasteruptiinae (Hymenoptera: Gasteruptiidae) based on a cladistic analysis, with the description of two new Neotropical genera and the revalidation of Plutofoenus Kieffer

Gasteruptiinae is the largest Gasteruptiidae subfamily, with circa 400 species that have been grouped into the worldwide Gasteruption Latreille. Based on a cladistic analysis with 43 morphological characters, 40 ingroup taxa representing all biogeographic regions, and seven outgroups (four Hyptiogastrinae, two Aulacidae and one Evaniidae), I confirm the monophyly of Gasteruptiinae and Gasteruption and recognize three exclusively Neotropical small genera: Plutofoenus Kieffer (revalidated) (southern South America), Spinolafoenus Macedo n. gen. (Chile) and Trilobitofoenus Macedo n. gen. (Central and South America). Gasteruption, supported by four synapomorphies, remains the most speciose genus in the subfamily. The four Gasteruptiinae genera are keyed and described. Seven species are keyed and described or redescribed: Plutofoenus chaeturus (Schletterer) n. comb., P. edwardsi Turner, P. paraguayensis (Schrottky), Spinolafoenus ruficornis (Spinola) n. comb., Trilobitofoenus alvarengai Macedo n. sp., T. plaumanni Macedo n. sp. and T. sericeus (Cameron) n. comb. (lectotype designated).

Two new species of Baetodes Needham & Murphy (Ephemeroptera : Baetidae) from Brazil

Baetodes santatereza, new species, and B. liviae, new species, are described based on nymphs collected from Sao Paulo, and Parana states, Brazil. They both possess one gill on each coxa and tubercles on metanotum and abdominal segments 1 - 9. Besides these characteristics, they can be distinguished from the other known species of the genus by the following combination of characters: B. santatereza, n. sp., glossae with two bladelike setae, one pectinate and one nonpectinate, and dorsal edge of femora with five to seven clavate setae, nearly one half the length of long, fine setae; B. liviae, n. sp., glossae with one pectinate bladelike setae, dorsal edge of femora often with 6 to 8 clavate setae, nearly the length of long fine setae, besides body color pattern and body length.

Description of the immature stages of Notalina morsei Holzenthal, 1986 (Trichoptera : Leptoceridae) and an updated key to larvae of Neotropical Leptoceridae genera

The endemic Neotropical long-horned caddisfly subgenus Notalina (Neonotalina) Holzenthal contains nine described species, but its immature stages are unknown. In this paper the larvae and pupae of Notalina morsei Holzenthal 1986 from southeastern Brazil are described and illustrated. Larvae of the subgenus are easily recognized from other Neotropical leptocerids by the following characters: ventral apotome which is broad anteriorly and narrow posteriorly; the metanotum with three sclerites; the metasternum bearing 10-12 setae; the gill arrangement, usually including ventral and dorsal filaments from abdominal segments II to VI; and abdominal tergite IX with 6 long and 4 short setae. An updated key to known larvae of Neotropical Leptoceridae genera is provided.

A new social parasite in the ant genus Ectatomma F. Smith (Hymenoptera, Formicidae, Ectatomminae)

Ectatomma parasiticum Feitosa & Fresneau, a new ant species socially parasitic on Ectatomma tuberculatum (Olivier), is described from gynes discovered in Apazapan, state of Veracruz, Mexico, and reared in the laboratory. Ectatomma parasiticum is the first social parasite described in the Ectatomminae. This species can be distinguished from its host by morphological and behavioral features characteristic of the inquilines known in other ant subfamilies including reduced size, thickened petiole, and agonistic interactions with host species.

A revision of Benedenia Diesing, 1858 including a redescription of B-sciaenae (van Beneden, 1856) Odhner, 1905 and recognition of Menziesia Gibson, 1976 (Monogenea : Capsalidae)

Benedenia Diesing, 1858, a genus of capsalid (benedeniine) monogeneans, is redefined. The generic diagnosis is amended to include: the path of tendons in the haptor from extrinsic muscles in the body; presence and form of the marginal valve; a penis occupying a penis canal with weakly muscular wall; a weakly muscular accessory gland reservoir proximal to the penis and enclosed by a proximal extension of the wall of the penis canal; male and female genital apertures usually common, rarely separate; vagina with pore usually close to the common genital pore but may open in mid body between the germarium and the common genital pore, or anterior to the common genital pore. A conservative approach is adopted and the generic diagnosis is clarified and broadened to accommodate species that display some variation in reproductive anatomy, especially of the female system. We argue against potential alternative actions such as defining Benedenia strictly to contain species with separate male and female genital apertures and against recognition of a separate genus, Tareenia Hussey, 1986, for species with a vaginal pore anterior to the common genital pore. Under our conception, Benedenia comprises 21 species: B. sciaenae (van Beneden, 1856) Odhner, 1905 (type species); B. acanthopagri (Hussey, 1986) comb. nov.; B. anticavaginata Byrnes, 1986; B. bodiani Yamaguti, 1968; B. elongata (Yamaguti, 1968) Egorova, 1997; B. epinepheli (Yamaguti, 1937) Meserve, 1938; B. hawaiiensis Yamaguti, 1968; B. hendorffi(von Linstow, 1889) Odhner, 1905; B. hoshinai Ogawa, 1984; B. innobilitata Burhnheim Gomes and Varela, 1973: B. jaliscana Bravo-Hollis, 1952; B. lolo Yamaguti, 1968; B. lutjani Whittington and Kearn, 1993: B. monticellii (Parona and Perugia, 1895) Johnston, 1929; B. ovata (Goto, 1894) Johnston. 1929: B. pompatica Burhnheim, Gomes and Varela, 1973; B. rohdei Whittington, Kearn and Beverley-Burton, 1994; B. scari Yamaguti, 1968; B. sekii (Yamaguti, 1937) Meserve, 1938; B, seriolae (Yamaguti, 1934) Meserve, 1938; and B. synagris Yamaguti, 1953. The type species, B. sciaenae, is redescribed based on new material from Australia. No types for this taxon were designated and we have assigned a series of voucher specimens. Tareenia acanthopagri Hussey, 1986 becomes B. acanthopagri (Hussey, 1986) comb. nov. and T. anticavaginata (Byrnes, 1986) Egorova, 1997 and T. lutjani (Whittington and Kearn, 1993) Egorova, 1997 are returned to Benedenia as B. anticavaginata and B. lutjani Benedenia akaisaki Iwata, 1990 is considered a synonym of B. ovata and B. kintoki Iwata, 1990 is considered a synonym of B. elongata. Two species, B, madai Ishii and Sawada, 1938 and B. pagrosomi Ishii and Sawada, 1938, are considered species inquirendae. Based on the redefinition of Benedenia, the diagnosis for the Benedeniinae is amended. Tareenia is synonymized with Benedenia but Menziesia Gibson, 1976 is recognized and its generic diagnosis amended to include: anterior attachment organs tending to form a 'hooded' appearance; prominent anterior gland cells between the pharynx and the anterior margin of the body: long penis, tapering proximally, occupying a penis canal with weakly muscular wall: penis canal and penis describe a sigmoid; accessory gland reservoir dorsal and alongside, or posterior and lateral to, proximal end of the penis and enclosed by a proximal extension of the wall of the penis canal. Under this conception. Menziesia comprises: M. noblei (Menzies. 1946) Gibson, 1976 (type species); M. malaboni (Velasquez. 1982) comb. nov.: M. merinthe (Yamaguti, 1968) Gibson. 1976: M. ovalis (Yamaguti, 1968) Gibson, 1976: and M. sebastodis (Yamaguti, 1934) comb, nov. A key to valid species of Benedenia and Menziesia is provided and a list is presented of published records of undescribed or unattributed species of Benedenia. Some protocols are suggested for preparation of benedeniine material to enhance future taxonomic studies and comparisons. The host-specificity and geographic distribution of species in these revised genera are discussed. The composition of the Capsalidae is discussed and some difficulties in defining and distinguishing between its different subfamilies are considered.

The genus Corallina (Corallinaceae, Corallinales, Rhodophyta) in the Azores (NE Atlantic): character expression and taxonomic evaluation

Morphological and anatomical characters used for segregating species within the genus Corallina (Corallinaceae, Rhodophyta) have been compiled and evaluated in 120 specimens collected in the Azores. The morphological, anatomical and statistical evaluation of the thirty four segregating characters for the genus Corallina performed in the present study revealed no species segregation, either showing no differences across the whole lot of specimens or being highly variable within sets of plants. This suggests that all studied material belongs to one species, so far Ellisolandia elongata (formely Corallina elongata), thus reinforcing old proposed synonyms. A morphological and anatomical account is provided for this species, considering the whole set of studied specimens.

Rhodolith forming coralline algae in the Upper Miocene of Santa Maria Island (Azores, NE Atlantic) : a critical evaluation

The Late Miocene Malbusca outcrop is located in the southeastern coast of Santa Maria Island (Azores, NE Atlantic), interspersed in volcanic formations. At ~20 meters above present sea level, a prominent discontinuous layer of rhodoliths seizes with an extension of ~250 meters. This paper presents the first taxonomic record of fossil rhodolith forming coralline algae for the Miocene of the Azores. The preserved taxonomic features used were the following: (1) arrangement of basal filaments, (2) epithallial cells (when observable), (3) presence of cell fusions, (4) conceptacle type, (5) number of cells layers which conceptacle chamber floors are situated below the surrounding thallus surface and (6) for the sporangial pores, the orientation of the filaments around the conceptacle pores. Based on these characters, six taxa were identified encompassing three Corallinaceae (Lithophyllum prototypum, Lithophyllum sp., Spongites sp., Hydrolithon sp.) and one Hapalidaceae (Phymatolithon calcareum and cf. Phymatolithon sp.). An unidentified coaxial thallus was also present, the coaxial construction ascribing the specimens to the genus Mesophyllum or Neogoniolithon. Taxonomic accounts for the identified taxa are described, illustrated and an identification key is provided. The report of L prototypum represents the first Miocene record and the preservation of the specimens is very good. Miocene coralline algae seem very consistent among deposits but some species are relevant for particular areas, like in the Azores.

Avaliação exploratória de atuação bienal do Programa Integrado de Doenças Endêmicas do Conselho Nacional de Desenvolvimento Científico e Tecnológico - PIDE/CNPq

Revisa se inicialmente a identidade básica do Programa Integrado de Doenças Endêmicas (PIDE), iniciativa do Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq), destinado ao fomento diferenciado nas áreas de Doença de Chagas, Esquistossomose, Malária, Leishmanioses e outras endemias relevantes (I). Descrevem-se, a seguir, procedimentos e resultados da avaliação exploratória de sua sexta fase bienal (PIDE VI): os aspectos científicos propostos para investigação foram atividade, produtividade e progresso; dados primários foram coletados através de questionários respondidos por 73,3% dos responsáveis pelos 195 projetos financiados, complementando os com informações institucionais disponíveis (II); apurou-se, ao final, volume, custo global e custo médio de projeto por área- distribuição das alocações por regiões geográficas e universidades do país mais freqüentemente contempladas. Tais indicadores revelaram alta atividade e produtividade, sobretudo na área de Doença de Chagas, região Sudeste e cinco Universidades brasileiras (III). A exploração desses comportamentos observados nos projetos, aparentemente mais afeitos às características dos estudiosos do que dos estudados, constitui o objeto da discussão (IV).

Proteolytic processing of the Cyt1Ab1 toxin produced by Bacillus thuringiensis subsp. medellin

Bacillus thuringiensis produces d-endotoxins that require proteolytic processing to become active. The activation of the B. thuringiensis subsp. medellin 28 kDa (Cyt1Ab1) cytolytic toxin by trypsin, chymotrypsin and gut extract from Culex quinquefasciatus larvae was analyzed. The Cyt1Ab1 toxin of B. thuringiensis subsp. medellin was processed by all proteases tested to fragments between 23 and 25 kDa, while processing of the Cyt1Aa1 toxin produce fragments between 22.5 and 24.5 kDa. The Cyt1Ab1 toxin was preferentially processed at the alkaline pH of 12. The in vitro proteolytic processing of the Cyt1Ab1 toxin by C. quinquefasciatus larvae midgut extract showed a 25 kDa fragment; a similar result was observed when the activation was performed in the in vivo experiments. The solubilized Cyt1Ab1 toxin and the protease resistant cores generated by in vitro processing showed hemolytic activity but not mosquitocidal activity. Amino terminal sequence of the C. quinquefasciatus gut extract resistant fragment indicated that the cutting site was located between Lys31 and Asp32, with a sequence DDPNEKNNHNS; while for the trypsin-resistant fragment the cutting site was determined between Leu29 and Arg30, and for the chymotrypsin-resistant fragment between Arg30 and Lys31.

Intervención en salud pública relacionada con la proliferación de microalgas tóxicas en una playa de Mijas (Málaga; España)

This paper provide an overview of the surveillance environmental efforts and risk management for the public health linked to the register of a disease outbreak related to an episode of toxic potentially and harmful microalgae, identified during the summer of 2010 in a recreational beach of a touristic municipality in the coast of Málaga (Spain). Phytoplankton analyses showed the presence of different species producers of marine biotoxins, dominating Ostreopsis cf. ovata in the followed immediately days to the communication of 39 clinical cases of people that required health cares. The risks of the toxins produced by microalgae must be taken into account in the health networks surveillance for recreational waters. This study suggests the possibility to review the actions of the public health services from Public Administration, to the light of the increasing information on episodic harmful algal blooms.
