Triatoma melanosoma, novo status para Triatoma infestans melanosoma Martinez, Olmedo & Carcavallo, 1987 (Hemiptera: Reduviidae)

Triatoma infestans melanosoma was described in 1987 by Martinez, Olmedo & Carcavallo. In the present work the authors make a redescription, adding new characters, and based on biological and morphological aspects raise up to the level of species and being identified as Triatoma melanosoma. A detailed morphological study of the external male genitalia was made.

Female genital mutilation and its prevention: a challenge for paediatricians.

Female genital mutilation (FGM) is defined as an injury of the external female genitalia for cultural or non-therapeutic reasons. FGM is mainly performed in sub-Saharan and Eastern Africa. The western health care systems are confronted with migrants from this cultural background. The aim is to offer information on how to approach this subject. The degree of FGM can vary from excision of the prepuce and clitoris to infibulation. Infections, urinary retention, pain, lesions of neighbouring organs, bleeding, psychological trauma and even death are possible acute complications. The different long-term complications include the risk of reduced fertility and difficulties during labour, which are key arguments against FGM in the migrant community. Paediatricians often have questions on how to approach the subject. With an open, neutral approach and basic knowledge, discussions with parents are constructive. Talking about the newborn, delivery or traditions may be a good starting point. Once they feel accepted, they speak surprisingly openly. FGM is performed out of love for their daughters. We have to be aware of their arguments and fears, but we should also stress the parents' responsibility in taking a health risk for their daughters. It is important to know the family's opinion on FGM. Some may need support, especially against community pressure. As FGM is often performed on newborns or at 4-9 years of age, paediatricians should have an active role in the prevention of FGM, especially as they have repeated close contact with those concerned and medical consequences are the main arguments against FGM.

Distribution and hybridization between Culex pipiens and Culex quinquefasciatus (Diptera: Culicidae) in Argentina

To better undesrtand the distribution of Culex pipiens and Cx. quinquefasciatus in Argentina, samples were collected from six localities situated in a North-South line from Castelli (Chaco Province) to Puerto Madryn (Chubut Province). Identification was based on the morphology of male genitalia. Only Cx. quinquefasciatus was found in Castelli and Esperanza, while in Rosario, 95.3% belonged to this species and 4.7% represented hybrid forms. Southern samples included only Cx. pipiens. With the purpose of verfying if Cx. pipiens and Cx. quinquefasciatus hybridize, different crosses between the two species were perfomed. All crosses produced viable egg rafts. Hatching ranged from 70 to 100%, except in one cross, female Cx. pipiens x male Cx. quinquefasciatus, where a high incompatibility was observed (11.1%hatch). The F1 hybrids obtained all crosses were fertile. The finding of hybrid forms in nature can be interpreted as evidence for subspecific status of Cx. pipiens and Cx. quinquefasciatus in Argentina.

Límites teóricos de sujeto epistolar y sujeto poético románticos, en la literatura escrita por mujeres

El proyecto, desarrollado bajo los auspicios del grupo Cos i Textualitat, aborda las relaciones entre las categorías de sujeto poético y sujeto epistolar, en la literatura romántica escrita por mujeres, que abarca corpus textuales del siglo XIX y principios del siglo XX. Haciendo uso de las herramientas del comparatismo, de la teoría de la literatura y de los estudios de género y sexualidad, el proyecto en una primera instancia se detuvo a estudiar la obra de aquellas escritoras (en el ámbito de la literatura norteamericana, española e hispanomericana) que desarrollaron e impulsaron el subgénero de la cartapoema, y cómo dicho subgénero les permitía velar su espacio íntimo, enmascarar su identidad literaria y social, al tiempo que obtenían legitimación social en esta estrategia de escritura. De este modo, el proyecto insiste en las estrategias de lectura de este tipo de textos, marginados por la crítica literaria, y de un tratamiento clasificatorio ciertamente ambiguo, y al mismo tiempo contaminado por la lectura autobiográfica de los textos. Cabe destacar que el punto de partida de este proceso de investigación fue la obra de la escritora norteamericana Emily Dickinson (1830-1886), pero se extendió con posterioridad desde autoras del romanticismo hispanoamericano, incluso hasta llegar a autoras españolas que escapan al movimiento romántico, bien entrado ya el siglo XX.

Taxonomy and biology of Culex (Culex) maxi Dyar (Diptera: Culicidae) in South America

Culex (Culex) maxi Dyar is described in the adult, pupal and larval stages, and the male genitalia and parts of the fourth-instar larva are illustrated. The larva is described for the first time. The paper includes a summary of available information on the taxonomy, bionomics and distribution of the species. The taxonomy and identification of the species are reviewed in light of current knowledge of the subgenus Culex in the New World.

Hermanlentia n. gen. da tribo Triatomini, com um rol de espécies de Triatominae (Hemiptera, Reduviidae)

Hermanlentia n. gen. of Tribe Triatomini, with a List of Species of Triatominae (Hemiptera, Reduviidae) - Hermanlentia n. gen. was established in the tribe Triatomini, based on differences of external morphology, phallic structures and chromatic characters of Triatoma matsunoi Fernandez-Loayza 1989, in relation to other species of Triatoma. The head is long with disproportionally small eyes 1:0,16; the relation of the head and the pronotum is 1: 0,4; and the coloration of the hemelytron is whitish. Characters of the male genitalia that distinguish the new genus are the articulatory apparatus with twice the size of the aedeagus, phallosoma with fingerlike apex, 1 + 1 dorsal conjuntive processes with the inner edge toothed, and absence of endosoma process and vesica

Holy harlots : authority, gender, and the body in medieval English hagiography

This doctoral dissertation aims at describing the representation of holy harlots (Mary Magdalene, Mary of Egypt, Pelagia, Thai's, Afra of Augsburg) in medieval English hagiography. These saints are unique representatives that combine both extremes of the feminine in the medieval imaginaire: she is both, as a saint, the Virgin Mary, the pure and virtuous woman, and, in her past as a prostitute, Eve, the evil female tempter who led all mankind to destruction. The initial question of this thesis is how did hagiographers negotiate the representation of a formerly sinful, sexually active, long- living woman as an authoritative saint? This thesis aims at finding elements of answer to this question, investigating the intersections between gender and authority in the saints' lives of repentant prostitutes in all the vernaculars of medieval England: Old English, Anglo-Norman, and Middle English. It posits that the portrayal of holy harlots' authority and gender is dependent upon social, religious and literary shifts during the medieval period. My contention is that the harlot's gender portrayal changes over the course of the eleventh and twelfth centuries, due notably to the rise of affective piety and the important influence of the romance genre over hagiography. In Anglo-Saxon England, the harlot's gender changes with the saint's conversion: a woman beforehand, her gender is portrayed after her repentance as ambiguous in order for her to become a saint. Her authority derives from her own sanctity in this case. From the twelfth century onward, however, the harlot, now often turned into a beautiful and landed romance lady, is more and more represented as a woman throughout her life, and becomes after her conversion a Bride of Christ. In this way, the dangerously free woman who roamed the streets and prostituted her body becomes less threatening after her conversion, being (re-)inscribed within the male dominated institution of marriage. She now draws her authoritative stance from her gendered intimacy with Christ: although she submits to Christ as his bride, she also gains greater authority than before by way of her privileged relationship with the Savior.

Triatoma jurbergi sp. n. do Norte do Estado do Mato Grosso, Brasil (Hemiptera, Reduviidae, Triatominae) com uma Atualização das Sinonímias e outros Táxons

Triatoma jurbergi n. sp. is described based on nine specimens of both sexes deposited in the Rodolfo Carcavallo Collection in the Oswaldo Cruz Institute Entomological Collection. The new species can be separated from the closely related Triatoma guazu Lent & Wygodzinsky, 1979 by several characters. The most important are longer anteocular region; thin and pointed juga; the shape of the eyes without concavity in the posterior edge; much longer second rostral segment, passing the posterior edge of eye; the absence of a ventral longitudinal depression on the abdomen; the general color redish, brown and orange and the male genitalia, mainly in the vesica lightly chitinized and smaller, the phallosome with apical projection and the pointed apex of the endosome process.

Triatoma bassolsae sp. n. from Mexico with a key to species of "phyllosoma" complex

According to the descriptions of five closely related species of the genus Triatoma Laporte, 1832: T. phyllosoma (Burmeister, 1835), T. pallidipennis (Stal, 1872), T. picturata Usinger, 1939, T. longipennis Usinger, 1939 and T. mazzottii Usinger, 1941 and further published studies, these species could be included in a "specific complex" named as the species formerly described. All these species are typical from Mexico and another species was found in the same country, in the State of Puebla: Triatoma bassolsae sp. n. This species was morphologically compared with the other five of the "phyllosoma" complex, including the external male genitalia. The most important characters used to separate T. bassolsae from T. phyllosoma (which is the most similar to the other species) are the morphometric relationships on the head, with a longer anteocular region and a significant longer second rostral segment, a long and conspicuous pilosity in different areas of the body and specially on the head, and the characters of the anterolateral, lateral and discal tubercles of the pronotum, very long and sharp in the new species. The male genitalia has several differences between T. bassolsae and T. phyllosoma specially significant on the surface of the endosome process and on the branches of the phallosome support, separated at the apex in the new species. Types and paratypes are incorporated in the respective institutions in Mexico DF and Rio de Janeiro.

Lutzomyia derelicta (Diptera: Psychodidae) a singular new phlebotomine sand fly from an inselberg in northeastern amazonia

Lutzomyia derelicta n. sp. is described from specimens collected in an isolated xeric habitat in the rainforest in the north of the State of Pará, Brazil. The new species lacks the posterior bulge in the dorsal wall of the cibarium characteristic of the New World genus Lutzomyia, and the armature of the male genitalia is of the pattern found elsewhere only in the Old World species of Sergentomyia. L. derelicta is phenetically intermediate between the known species of Lutzomyia and Sergentomyia, and cannot readily be placed in any existing subgenus or species group of either genus.

The subgenus Dendromyia theobald: a review with redescriptions of four species (Diptera: Culicidae)

A morphological study of larval, pupal and adult life stages (including genitalia characters) was performed in order to evaluate the classification of the subgenus Dendromyia, genus Wyeomyia Theobald. Six species are included: Wy. ypsipola Dyar, Wy. jocosa (Dyar & Knab), Wy. testei Senevet & Abonnenc, Wy. complosa (Dyar), Wy. luteoventralis Theobald and Wy. trifurcata Clastrier, the first four of which are redescribed. The descriptions include illustrations of the male and female genitalia, fourth-instar larva and pupa. The result firmly supports Dendromyia as a monophyletic group, with well defined characters. Keys for the identification of all life stages of species included in Dendromyia are provided.

Innovation or Imitation? The effect of spillovers and competitive pressure on firms' R&D strategy choice

This article provides a theoretical and empirical analysis of a firm's optimal R&D strategy choice. In this paper a firm's R&D strategy is assumed to be endogenous and allowed to depend on both internal firms. characteristics and external factors. Firms choose between two strategies, either they engage in R&D or abstain from own R&D and imitate the outcomes of innovators. In the theoretical model this yields three types of equilibria in which either all firms innovate, some firms innovate and others imitate, or no firm innovates. Firms'equilibrium strategies crucially depend on external factors. We find that the efficiency of intellectual property rights protection positively affects firms'incentives to engage in R&D, while competitive pressure has a negative effect. In addition, smaller firms are found to be more likely to become imitators when the product is homogeneous and the level of spillovers is high. These results are supported by empirical evidence for German .rms from manufacturing and services sectors. Regarding social welfare our results indicate that strengthening intellectual property protection can have an ambiguous effect. In markets characterized by a high rate of innovation a reduction of intellectual property rights protection can discourage innovative performance substantially. However, a reduction of patent protection can also increase social welfare because it may induce imitation. This indicates that policy issues such as the optimal length and breadth of patent protection cannot be resolved without taking into account specific market and firm characteristics. Journal of Economic Literature Classification Numbers: C35, D43, L13, L22, O31. Keywords: Innovation; imitation; spillovers; product differentiation; market competition; intellectual property rights protection.

Nova espécie do complexo oliveirai (nova denominação para o complexo matogrossensis) (Hemiptera, Reduviidae, Triatominae) do estado do Rio Grande do Sul, Brasil

The authors describe a new species of Triatominae (Hemiptera, Reduviidae) from the State of Rio Grande do Sul, Brazil. The study was made with specimens captured in basaltic formations, at an average altitude of 750 m.o.s.l. The new species is included in the oliveirai complex together with other four species T. williami, T. matogrossensis, T. guazu and T. jurbergi). The new species was compared with the most similar one, T. oliveirai, from which the main differences are on the proportions of head, ante and postocular regions, the general color pattern and the male genitalia, specially on the median process of the pygophore, the support of phallosome, the vesica and the process of the endosome.

Rhodnius amazonicus Almeida, Santos & Sposina, 1973, Bona Species, Close to R. pictipes Stål, 1872 (Heteroptera, Reduviidae, Triatominae)

The discovery of two atypical specimens of Rhodnius pictipes Stål, 1872 in French Guiana and the examination of the female holotype of R. amazonicus Almeida, Santos & Sposina, 1973, the only specimen of this species so far known, lead us to propose the rehabilitation of R. amazonicus synonymized with R. pictipes. The male is described for the first time and the female redescribed. Both external characters and genitalia distinguish R. amazonicus from R. pictipes. R. amazonicus shows affinities not only with pictipes but also with R. stali Lent, Jurberg & Galvão, 1993 and R. paraensis Sherlock, Guitton & Miles, 1977. A key is provided for these four species forming, in all likelihood, a natural group, i.e. the "pictipes group".
