Description and phylogenetic analysis of the Calycopidina (Lepidoptera, Lycaenidae, Theclinae, Eumaeini): a subtribe of detritivores

Description and phylogenetic analysis of the Calycopidina (Lepidoptera, Lycaenidae, Theclinae, Eumaeini): a subtribe of detritivores. The purpose of this paper is to establish a phylogenetic basis for a new Eumaeini subtribe that includes those lycaenid genera in which detritivory has been recorded. Morphological characters were coded for 82 species of the previously proposed "Lamprospilus Section" of the Eumaeini (19 of these had coding identical to another species), and a phylogenetic analysis was performed using the 63 distinct ingroup terminal taxa and six outgroups belonging to four genera. Taxonomic results include the description in the Eumaeini of Calycopidina Duarte & Robbins new subtribe (type genus Calycopis Scudder, 1876), which contains Lamprospilus Geyer, Badecla Duarte & Robbins new genus (type species Thecla badaca Hewitson), Arzecla Duarte & Robbins new genus (type species Thecla arza Hewitson), Arumecla Robbins & Duarte, Camissecla Robbins & Duarte, Electrostrymon Clench, Rubroserrata K. Johnson & Kroenlein revalidated status, Ziegleria K. Johnson, Kisutam K. Johnson & Kroenlein revalidated status, and Calycopis. Previous "infratribe" names Angulopina K. Johnson & Kroenlein, 1993, and Calycopina K. Johnson & Kroenlein, 1993, are nomenclaturally unavailable and polyphyletic as proposed. New combinations include Badecla badaca (Hewitson), Badecla picentia (Hewitson), Badecla quadramacula (Austin & K. Johnson), Badecla lanckena (Schaus), Badecla argentinensis (K. Johnson & Kroenlein), Badecla clarissa (Draudt), Arzecla arza (Hewitson), Arzecla tarpa (Godman & Salvin), Arzecla canacha (Hewitson), Arzecla calatia (Hewitson), Arzecla tucumanensis (K. Johnson & Kroenlein), Arzecla sethon (Godman & Salvin), Arzecla nubilum (H. H. Druce), Arzecla paralus (Godman & Salvin), Arzecla taminella (Schaus), Arzecla albolineata (Lathy), Electrostrymon denarius (Butler & H.Druce), Electrostrymon guzanta (Schaus), Electrostrymon perisus (H. H. Druce), Rubroserrata mathewi (Hewitson), Rubroserrata ecbatana (Hewitson), Kisutam micandriana (K. Johnson), and Kisutam syllis (Godman & Salvin). The structure of the male genitalia lateral window, labides, and brush organs are described and discussed, as are the female genitalia signa of the corpus bursae and 8th abdominal tergum. Widespread wing pattern sexual dimorphism in the Calycopidina is noted and illustrated, and the presence of alternating dark and light bands on the ventral wings of both sexes is discussed. The evidence for detritivory in Lamprospilus, Badecla, Arzecla, Arumecla, Camissecla, Electrostrymon, Ziegleria, Kisutam, and Calycopis is summarized using the new classification.

Trichopeltariidae (Crustacea, Decapoda, Brachyura), a new family and superfamily of eubrachyuran crabs with description of one new genus and five new species

A new family, Trichopeltariidae, is proposed to accommodate Sphaeropeltarion edentatum, new genus and species, and four additional genera traditionally placed in the family Atelecyclidae: Trichopeltarion A. Milne-Edwards, 1880 (type genus); Peltarion Hombron & Jacquinot, 1846; Podocatactes Ortmann, 1893; and Pteropeltarion Dell, 1972. Additionally, four new species of Trichopeltarion are described and illustrated. The new family exhibits characters of neither superfamilies of the Section Eubrachyura and is assigned to its own superfamily, Trichopeltarioidea nov. Keys to the genera of Trichopeltariidae fam. nov. and to all species in the family are presented (species of Trichopeltarion excepted). Six new combinations are proposed or confirmed. The genus Krunopeltarion Števčić, 1993, is merged into the synonymy of Trichopeltarion. A lectotype is selected for Trichopeltarion corallinum (Faxon, 1893).

Revision of the genus Physoclypeus Hendel, 1907 (Diptera, Lauxaniidae), with description of seven new species

The genus Physoclypeus Hendel, 1907 has its distribution restricted to the Neotropical region. In this study, its species have been redescribed, three new combinations have been proposed, three lectotypes have been designated, seven new species have been described, and an identification key to the species is presented. An updated list of species of Physoclypeus is presented as: P. annulatus Hendel, 1925; P. coquilletti (Hendel, 1908); P. farinosus (Hendel, 1925); P. flavus (Wiedemann, 1830); P. hendeli sp. nov.

(Type locality, Brazil, Santa Catarina); P. risaraldensis sp. nov. (Type locality, Colombia, Risaralda); P. saltensis sp. nov. (Type locality, Argentina, Salta); P. scutellatus (Curran, 1926) new comb.; P. unimaculatus sp. nov. (Type locality, Mexico, Vera Cruz); P. vitattus sp. nov. (Type locality, Brazil, Santa Catarina) and P. zebrinus sp. nov. (Type locality, Costa Rica, Limón).

Description of Micropygomyia brandaoi sp. n. (Diptera: Psychodidae: Phlebotominae), a fossil phlebotomine from the Dominican Republic

The description of Micropygomyia brandaoi, a new species of fossil phlebotomine sand fly, is based on one male specimen obtained from Dominican amber of the Miocene period (20 million years). In this new species, the fifth palpal segment is long, the coxite lacks a setal tuft and the style shows four well-developed spines. This set of characters allowed us to place the new species in the genus Micropygomyia Barretto.

O papel das Classificações da OMS - CID e CIF nas definições de deficiência e incapacidade

A Organização Mundial de Saúde tem hoje duas classificações de referência para a descrição dos estados de saúde: a Classificação Estatística Internacional de Doenças e Problemas Relacionados à Saúde, que corresponde à décima revisão da Classificação Internacional de Doenças (CID-10) e a Classificação Internacional de Funcionalidade, Incapacidade e Saúde (CIF). A utilização da CIF vem sendo aguardada com grande expectativa pelas organizações de pessoas com deficiências e instituições relacionadas. A falta de definição clara de "deficiência" ou "incapacidade" tem sido apontada como um impedimento para a promoção de saúde de pessoas com deficiência. É importante que essas definições, especialmente no âmbito legislativo e regulamentar, sejam consistentes e se fundamentem num modelo coerente sobre o processo que origina as situações de incapacidade. Este artigo tem como objetivo apresentar elementos da CID-10 e da CIF, e o papel que desempenham para definir deficiência e incapacidade. Os componentes da CIF podem contribuir para diferentes campos de aplicabilidade no que diz respeito ao entendimento das definições de deficiência ou incapacidade a partir do conceito de funcionalidade e dos fatores contextuais.

A "reeducação" de adolescentes em uma comunidade terapêutica: o tratamento da drogadição em uma instituição religiosa

O abuso de drogas por adolescentes é, atualmente, um grave problema de saúde pública. Nessa área, a questão do tratamento destaca-se como um grande desafio, principalmente pelo fato de a maioria das intervenções não estar adaptada às especificidades desse público. Neste trabalho, serão apresentados os resultados de uma investigação que visou analisar o tratamento destinado a adolescentes em uma modalidade de atenção distinta das abordagens tradicionais da área da saúde: a comunidade terapêutica. Buscou-se compreender as concepções e práticas de atenção da instituição pesquisada, comparando-as com o prescrito pelas políticas públicas do setor. Os métodos utilizados foram a descrição etnográfica e a análise de conteúdo. Os resultados sugerem uma defasagem entre o prescrito pelas políticas públicas e a realidade da comunidade terapêutica pesquisada, a qual, apesar de proporcionar acolhimento às adolescentes, dificulta o desenvolvimento de suas singularidades e potencialidades devido à ênfase no "modelo moral" de tratamento da drogadição.

Redescription of Anopheles (Nyssorhynchus) antunesi Galvão & Amaral and description of a new species of the Myzorhynchella Section (Diptera: Culicidae) from Serra da Mantiqueira, Brazil

Anopheles (Nyssorhynchus) pristinus Nagaki & Sallum, n. sp. of the Myzorhynchella Section is described based on morphological characters of adult females, males, fourth-instar larvae, pupae and male genitalia. Anopheles (Nyssorhynchus) antunesi Galvão & Amaral is characterized to fix its identity and distinguish it from An. pristinus. The eggs of An. antunesi are described for the first time. Molecular characterization employing sequences of the COI mitochondrial gene and the ITS2 region of ribosomal DNA are provided for each species. An. antunesi and An. pristinus are compared with morphologically similar species of the Myzorhynchella Section. The results of the present study suggest that the new species has been misidentified as both An. antunesi and Anopheles lutzii Cruz. An. antunesi and An. pristinus are sympatric, occurring at high altitudes in Serra da Mantiqueira, southeastern Brazil

Review of American fossil phlebotominae (Diptera: Psychodidae) with a description of two new species

The objective of this study was to carry out a taxonomic review of fossil American phlebotomine sand flies and describe two new species found in amber in the Dominican Republic. The gonostyle of one of these, Micropygomyia dorafeliciangeliae nov. sp., (=Lutzomyia dorafeliciangeliae, species group oswaldoi), has five spines, similar to that of Micropygomyia paterna (Quate, 1963) (= Lutzomyia paterna, species group oswaldoi), but they may be distinguished by the alpha/gamma ratio, which is <1.0 in the new species and >1 in the latter. Pintomyia dominicana nov. sp. (=Lutzomyia dominicana, species group verrucarum) has four spines on the gonostyle and presents a long bristle on the apex of the paramere, which distinguishes it from the other fossil species. With the description of these two new species, a total of 14 species of the American fossil phlebotomine sand flies has been described, 10 of which belong to the genus Pintomyia. An identification key for male fossil species is presented

Description of the immatures of the ant, Myrmelachista catharinae

The Neotropical ant genus Myrmelachista Roger comprises 69 described species and subspecies, and still is a poorly studied group. Larvae play a paramount role in colony nutrition in social hymenopterans and bear considerable value in the reconstruction of group phylogenies, however, they are generally neglected. Larvae of different instars of Myrmelachista catharinae Mayr (Hymenoptera: Formicidae) are herein described in detail by light and scanning electron microscopy. The number of larval instars was estimated as three based on the frequency distribution of maximum head capsule widths. The described larvae confirmed some traits typical of the genus: general shape of body and mandibles, general aspect and distribution of body hairs, and the number of sensilla on the palps and galea. Differently from other Myrmelachista larvae previously described, M. catharinae presented two distinct kinds of second instars, some additional types of body hairs, different number of antennal sensilla, and a distinct labrum shape. M. catharinae presented ten pairs of spiracles, which is the first record for this genus.

DESCRIPTION OF THE LARVAE OF TAPINOMA MELANOCEPHALUM (HYMENOPTERA: FORMICIDAE)

Morphological descriptions of the 4 instars of the ghost-ant Tapinoma melanocephalum Fabricius are presented along with illustrations and comparisons with other species of the same genus. Instars were similar, differing only in body length. The analyzed larvae presented many characteristics in common with other Tapinoma Forster larvae, such as: dolichoderoid body and mandibles, 9 pairs of spiracles, the presence of a terminal boss, and scarce body and head setae, all simple and short. We observed the following differences from other previous descriptions: the presence of a subapical mandibular tooth, setaceous sensilla on the medial anterior surface of the labrum, and fewer sensilla on maxillary and labial palps.

DESCRIPTION OF THE IMMATURES OF WORKERS OF THE ANT CAMPONOTUS VITTATUS (HYMENOPTERA: FORMICIDAE)

Camponotus vittatus Forel is a poorly studied Neotropical ant, which is very common in Brazil. Larval descriptions are useful to systematics, as larval characters aid with genus-level differentiation, and ant larvae lie at the basis of ant social organization. This study presents the first description of the immatures of C. vittatus with the aid of light and scanning electron microscopy. There are three instars based on the frequency distribution of larval head widths. The larvae had some characteristics typical of Camponotus, specifically, a 'pogono-myrmecoid' body shape, 10 pairs of spiracles, antennae with 3 sensilla, mature larvae with pronounced labial pseudopalps, and conspicuous 'chiloscleres' on the labrum. Unique characteristics found would include the greatest diversity of body hair types recorded in an ant larva and 'camponotoid' mandibles with 6 medial denticles over the blade. The number of antennal sensilla proved variable.

The Process of Simulation Authoring/Creation by Chemistry Teachers: A Service Learning Experience

Two case studies are presented to describe the process of public school teachers authoring and creating chemistry simulations. They are part of the Virtual Didactic Laboratory for Chemistry, a project developed by the School of the Future of the University of Sao Paulo. the documental analysis of the material produced by two groups of teachers reflects different selection process for both themes and problem-situations when creating simulations. The study demonstrates the potential for chemistry learning with an approach that takes students' everyday lives into account and is based on collaborative work among teachers and researches. Also, from the teachers' perspectives, the possibilities of interaction that a simulation offers for classroom activities are considered.
