Holotype male, ECUADOR, Manabi: La Pila (vicinity, 01º. 1196 S, 80 º. 5806 W, 200 m), 18– 27.II. 2006, F. T. Hovore & I. Swift col. (CASC). Paratype male, same data (CASC). Etymology. Latin, barbatus = having a beard, bearded; alluding to the pilosity of the antennae. Discussion. The genus Trichohippopsis Breuning, 1958 is restricted to South America and contains five species: T. exilis Galileo & Martins, 2006; T. magna Martins & Carvalho, 1983; T. rufula Breuning, 1958; T. suturalis Martins & Carvalho, 1983 and T. unicolor Galileo & Martins, 2007. Trichohippopsis barbatulus sp. nov. differs from other species by the very large head, as long as prothorax, by the upper ocular lobes projecting forward, and by the large depression on urosternite V. From T. unicolor, described from Brazil (Amazonas), it is distinguished by the evenly distributed elytral punctation and pilosity. In T. unicolor, elytra are strongly and densely punctate with a lateral area, from middle to distal fourth, microsculptured, with sparse punctures, and denser pilosity.Published as part of Martins, Ubirajara R. & Galileo, Maria Helena M., 2013, New species and records of Cerambycinae and Lamiinae (Coleoptera: Cerambycidae) from the Neotropical Region, pp. 571-580 in Zootaxa 3683 (5) on page 579, DOI: 10.11646/zootaxa.3683.5.5, http://zenodo.org/record/21812
As máscaras modernistas: Adalgisa Nery e Maria Martins na vanguarda brasileira
No full textDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro de Comunicação e Expressão. Programa de Pós-Graduação em Literatura.Certa tradição analisa as obras do modernismo brasileiro recorrendo à institucionalização nacionalista do movimento e pautando-se, muitas vezes, numa concepção materialista da história. Afora isso, esse olhar crítico é mediado pela percepção da forma como matéria a ser analisada, o que pressupõe um parâmetro que, na literatura brasileira, estaria na Semana de Arte Moderna. Este trabalho se propõe a focar duas autoras modernistas não-canônicas: Maria Martins (1890-1973) e Adalgisa Nery (1905-1980). Supõe-se que ambas as autoras passaram incólumes pelo movimento por adotarem uma concepção nietzscheana de tempo, circular. Deuses Malditos I (1965), biografia de Nietzsche escrita por Maria Martins e A imaginária (1959), romance autobiográfico de Adalgisa Nery, são analisados a partir da tese de que a biografia e a autobiografia são máscaras textuais. A máscara é matéria que revela pelo disfarce, que preenche os vazios diversos - a ausência de Maria e de Adalgisa na crítica, as lacunas presentes em ambos os livros e a impossibilidade de representação das autoras pelo texto. Tratar do modernismo por meio de máscaras permite pensá-lo a partir do texto e de um começo, ou de um re-começo, que pode existir ainda hoje. A determinate critical tradition analyses Brazilian modernist works considering the nationalist aspect of this movement. This tradition is based, most of the times, on a materialistic conception of history. Besides that, this critical perspective takes into account the structure as the main aspect to be analyzed in a literary work and considers the authors who took part in the Modern Week, in 1922, as patterns to read others modernist writers and texts. This paper focuses on two modernist non-canonical writers, Maria Martins (1890-1973) and Adalgisa Nery (1905-1980) assuming that they were not suitably considered as part of that literary movement because they have embraced a Nietzschean conception of time, an understanding of history as a cyclical movement. Deuses Malditos I (1965), Nietzsche's biography by Maria Martins and A imaginária (1969), Adalgisa's Nery autobiographical novel, will be analyzed departing from the theses that biography and autobiography are textual masks. Mask is the substance that reveals when hiding, which fills various vacuities - Maria's and Adalgisa's absence in literary criticism, the gaps present in both books and the textual impossibility of representing these writers. To deal with modernism by means of masks also allows to consider the notion of text and to depart from a beginning or from a reopening to think about this movement, what may be possible still nowadays

DNA fusion gene vaccination mobilizes effective anti-leukemic cytotoxic T lymphocytes from a tolerized repertoire
No full textThe majority of known human tumor-associated antigens derive from non-mutated self proteins. T cell tolerance, essential to prevent autoimmunity, must therefore be cautiously circumvented to generate cytotoxic T cell responses against these targets. Our strategy uses DNA fusion vaccines to activate high levels of peptide-specific CTL. Key foreign sequences from tetanus toxin activate tolerance-breaking CD4+ T cell help. Candidate MHC class Ibinding tumor peptide sequences are fused to the C terminus for optimal processing and presentation. To model performance against a leukemia-associated antigen in a tolerized setting, we constructed a fusion vaccine encoding an immunodominant CTL epitopederived from Friend murine leukemia virus gag protein (FMuLVgag) and vaccinated tolerant FMuLVgag-transgenic (gag-Tg) mice. Vaccination with the construct induced epitopespecificIFN-c-producing CD8+ T cells in normal and gag-Tg mice. The frequency and avidity of activated cells were reduced in gag-Tg mice, and no autoimmune injury resulted. However, these CD8+ T cells did exhibit gag-specific cytotoxicity in vitro and in vivo. Also, epitope-specific CTL killed FBL-3 leukemia cells expressing endogenous FMuLVgag antigen and protected against leukemia challenge in vivo. These results demonstrate a simple strategy to engage anti-microbial T cell help to activate epitope-specific polyclonal CD8+ T cell responses from a residual tolerized repertoire

TABLE 1. Measurements of Ischnocnema vizottoi sp. nov. (holotype and paratopotypes). Mean (x), standard deviation (SD), and range (in millimeters) for males and females. Comparison with other species. The new species differs from Ischnocnema sambaqui by its smaller size (I. vizottoi sp. nov. males 13.3–16.6 mm SVL and females 18.4–22.1 mm SVL; I. sambaqui males 32.3 –40.0 mm SVL), finger adhesive disks rounded (T-shape in I. sambaqui), narrower head, and higher dominant frequency of advertisement call (I. vizottoi sp. nov. 3417–3763 Hz, I. sambaqui 1800–2050 Hz; Castanho & Haddad, 2000). The new species differs from Ischnocnema manezinho by its smaller size (I. vizottoi sp. nov. males 13.3–16.6 mm SVL and females 18.4–22.1 mm SVL; I. manezinho males 22.7–28.1 mm SVL and females 29.8–34.8 mm SVL; Garcia, 1996), and finger adhesive disks rounded (T-shaped in I. manezinho). The new species differs from Ischnocnema bolbodactyla by its smoother dorsal skin, shorter snout, adhesive disks less developed, absence of bright coloration on the inguinal region (inguinal region bright orange in I. bolbodactyla), and advertisement call formed by a single note (formed by series of 3–4 notes in I. bolbodactyla). The new species differs from Ischnocnema lactea by its smaller size (I. vizottoi sp. nov. males 13.3–16.6 mm SVL and females 18.4–22.1 mm SVL; I. lactea female lectotype 32mm SVL) and finger adhesive disks rounded (T-shaped in I. lactea). The new species differs from Ischnocnema holti by its smaller size (I. vizottoi sp. nov. males 13.3–16.6 mm SVL and females 18.4–22.1 mm SVL; I. holti 19 mm SVL; Cochran, 1955; male mean SVL 21.2 mm and female SVL 25.6mm; Targino & Carvalho-e-Silva, 2008) and snout outline sub-elliptical from above and acuminate-rounded in profile (snout in dorsal and lateral views rounded in I. holti). The new species differs from Ischnocnema concolor by its smaller size (I. vizottoi sp. nov. males 13.3–16.6 mm SVL and females 18.4–22.1 mm SVL; I. concolor males 15.0– 18.4mm SVL; Targino et al., 2009), by a light line or irregular light blotches on the external face of the central area of the thigh (I. concolor lacks a light line or irregular light blotches in the central area of the thigh; Targino et al., 2009), and advertisement call traits [the notes in the advertisement call of I. vizottoi have two harmonics; minimum and maximum fundamental frequency (H 1) of 2780–3555 Hz, 3634–4097 Hz, respectively; the notes in the advertisement call of I. concolor have three harmonics; minimum and maximum fundamental frequency (H 1) of 2616–2989 Hz, 3150–3470 Hz, respectively; Martins, I.A. unpublished data]. The new species differs from Ischnocnema melanopygia by the smaller or absent calcar appendage (calcar appendage well developed in I. melanopygia; Targino et al., 2009) and by the absence of a black stripe on the perianal region, posterior area of tarsus, and feet (black stripe present in I. melanopygia; Targino et al., 2009).

The specimens of Ischnocnema vizottoi sp. nov. present wide variation of dorsal coloration (Figure 3). Dorsal coloration of different specimens can be green, red, black, brown, and light gray (Figure 3). A longitudinal light line extending from the snout to the vent is present in several specimens. A white or beige inter-orbital stripe is almost always visible, with a dark stripe behind the light inter-orbital stripe. Two dark blotches can be present in the middle of dorsum in some individuals. The external face of the thigh presents a light line in the central area or irregular light blotches. The subgular region may be lightly to very dark pigmented. In several specimens it is possible to see a light ventral line, from the anterior border of the chin to the chest. The ventral regions of the thigh and tibia present light spots with dark borders. Variation. Measurements of 27 males and five females are given in Table 1. The head is generally wider than long, but in some specimens it is longer than wide. The tympanum is distinct in the majority of the specimens. The vocal sac may be well expanded externally or indistinct. The calcar appendage may be smaller or absent. A light to dark stripe is generally present in the inter-orbital region. A light vertebral line is present in the majority of the specimens (Figures 3 and 4). The external face of the thigh may show a light line in the central area or irregular light blotches. Vocalization. The advertisement call of Ischnocnema vizottoi sp. nov. is composed of simple notes, with a fairly irregular rhythm and varied intervals (Figure 5). The average duration of the note is 52.7 ± 10.2 ms (38–72 ms), with a mean repetition rate of 9.5 ± 2.2 notes per minute. The advertisement call of Ischnocnema vizottoi sp. nov. has notes with two harmonics (Figure 5 B, D). The advertisement call has sharply rising frequencies at the beginning and sharply falling frequencies at the end (Figure 5). Most of the energy of these notes is concentrated in the first harmonic (fundamental frequency = H 1; Figure 5 E). The mean frequencies of the first harmonic (H 1) minimum frequencies is between 3204 ± 158 (amplitude 2780–3555 Hz) and maximum frequencies 3837 ± 95 Hz (amplitude 3634–4097 Hz), with most energy concentrated around 3611 ± 103 Hz (amplitude 3417–3763 Hz). The second harmonic (H 2) has minimum and maximum mean frequencies between 6967 ± 207 (amplitude 6585–7317 HZ), 7379 ± 119 Hz (amplitude 7146–7618 Hz) respectively, and most energy of the second harmonic is concentrated around 6996 ± 212 Hz (Figure 5). Distribution. The new species has been found in Serra da Mantiqueira at the localities of Parque Estadual de Campos do Jordão, Municipality of Campos do Jordão, São Paulo State, (type locality); Lavrinhas farm, Municipality of Pindamonhangaba, São Paulo State; Municipality of São Bento do Sapucaí, São Paulo State; Monte Verde, Municipality of Camanducaia, Minas Gerais State; and Serra do Mar, at Parque Nacional da Serra da Bocaina, Municipality of São José do Barreiro, São Paulo State. All the localities are in the Atlantic forest, above 1300 elevation (Figure 6). Etymology. The specific name honors Dr. Luiz Dino Vizotto, for his pioneer studies of Brazilian anurans and for his contribution to the knowledge of the Brazilian vertebrate fauna. Natural history. Ischnocnema vizottoi sp. nov. was observed in places of high altitude, from 1300 to 2100 m above sea level, inside forests, forest edges, and open fields. Males vocalize on the forest floor or perched 10 to 80 cm from the ground. The distance among neighboring males varied from 0.5 to 8 m. The calling season is from September to April; however, the vocalization was most intense from October to January, when gravid females were observed. Three analyzed females had from 10 to 18 oocytes with mean diameter of 2.45 ± 0.15 mm (N = 27). Oocytes in different developmental stages suggest that females may lay more than one clutch per season. Remarks. The Atlantic forest is the biome with the greatest endemism in species of anurans in the world, at the same time having high diversity of species and of phylogenetic groups (Duellman, 1999, Frost et al., 2006). This high diversity and endemism can be explained by the physical environment, a reflex of the complex geomorphologic, climatic, and phytogeographic characteristics of this formation. However, the species diversity of anurans in the Atlantic Forest of Brazil is still poorly known, particularly in places with more than 1000 m of altitude (Rossa-Feres et al., 2008). The number of species in the genus Ischnocnema will probably increase in the next years, considering the recent descriptions of new species (Giaretta et al., 2007; Targino et al., 2009) and mainly the large number of unnamed species that can be found in the shelves of Brazilian collections (personal observations). The use of molecular information and vocalizations, allied to morphological studies, will increase our comprehension on the evolution of this genus and certainly uncover a great diversity of cryptic species.Published as part of Martins, Itamar A. & Haddad, Célio F.
