Revisão do gênero Polyrhaphis Audinet-Serville (Coleoptera, Cerambycidae, Lamiinae)

Polyrhaphis Audinet-Serville, 1835, gênero de Lamiinae distribuído entre o México e América do Sul (excluindo o Chile e abaixo da latitude 35°S), é revisado. Três espécies novas são descritas: P. baloupae, procedente da Guiana Francesa; P. lanei, proveniente do Brasil (Amazonas e Pará); e P. peruana, do Peru. Duas espécies são sinonimizadas: P. testacea Lane, 1965 (= P. gracilis Bates, 1862) e P. paraensis [= P. papulosa (Olivier, 1795)]. É designado neótipo para P. papulosa. A autoria de P. horrida [= P. spinosa (Drury, 1773)] é discutida. Cerambyx armatus Voet (1778?) é considerado um nome inválido e Lamia armiger Schöenherr, 1817 (= Polyrhaphis armiger) o nome válido dessa espécie. Polyrhaphis spinipennis Laporte, 1840, é excluída da fauna da Colômbia. Novos registros de distribuição: P. argentina Lane, 1978, para o estado de São Paulo (Brasil); P. batesi Hovore & McCarty, 1998, para o Equador; P. belti Hovore & McCarty, 1998 para o Equador e Colômbia; P. gracilis Bates, 1862, para a guiana Francesa; e P. turnbowi Hovore & McCarty, 1998, em dúvida, para o Peru. É apresentada chave para as espécies do gênero.

The John Dewey`s epistemology and informational literacy

The `reflexive thinking` concept is discussed in this article as a means of contextualizing John Dewey`s intellectual legacy. `Reflection` represents a fundamental element for the construction of the necessary competences to information seeking and use, and consequently to individual and collective development. Since the reflexive thinking habit in information literacy is a way of learning, some questions concerning teaching and learning processes are also investigated. The discussion is, therefore, supported by the supposition that reflexive thinking is a cognitive strategy that allows a deeper comprehension of related problems, phenomena, and processes by means of the perception of the relations and the identification of involved elements, as well as the analysis and interpretation of meanings, empowering the information literacy process.

Diagnoses of and illustrated key to the species of Ixodes Latreille, 1795 (Acari: Ixodidae) from Brazil

The current Brazilian Ixodes fauna is composed of the following eight species: I. amarali Fonseca, 1935; I. aragaoi Fonseca, 1935; I. auritulus Neumann, 1904; I. fuscipes Koch, 1844; I. loricatus Neumann, 1899; I. luciae S,nevet, 1940; I. paranaensis Barros-Battesti, Arzua, Pichorim & Keirans, 2003; and I. schulzei AragA o pound & Fonseca, 1951. Further studies are needed to establish the taxonomic status of I. serrafreirei Amorim, Gazeta, Bossi & Linhares, 2003, a recently proposed species based solely on the nymphal stage. We present an up-to-date key to adults of the currently valid Brazilian species of Ixodes based on scanning electron microscopy. The relationships between Brazilian and other Neotropical Ixodes are also discussed.
