This species is distinguished from other Aglaoctenus, except for A. lagotis (Fig. 17) and A. castaneus, by the inverted T-shape of the median septum, without lateral projections (Fig. 8 a). The anterior lateral eyes on small tubercles (Figs 19 b, e) and the colour pattern of the carapace (Figs 7 a, c) distinguish this species from A. lagotis (Figs 16 a, c) and A. castaneus. Description. Female (holotype). Colour in ethanol (Figs 7, 19 c): carapace, dark reddish-brown, covered by dark setae, with light submarginal bands enhanced by white setae (orange in live specimens (Fig. 9)). Chelicerae, endites and labium, dark brown. Sternum reddish-brown, coxae brown. Venter of femora, patellae and basal third of tibiae, light brown, dorsally brown with darker areas; distal tibiae, metatarsi and tarsi brown. Scopulae dense from the tibiae through tarsi. Abdomen dorsally brown without clear pattern, ventrally light brown. Epigyne (Fig. 8 a), median septum with inverted T-shape, without lateral projections, covered by plumose setae. Internal genitalia (Figs 8 b, 18 b), spermatheca with a long and medially curved stalk, vulval chamber semioval. Head of spermatheca branched and with small projections. Fertilization duct small and membranous, connected to the base of spermatheca posteriorly. TL 18.09, CL 9.40, CW 7.45, CH 2.79.

The specific name is a noun in apposition after the fire of the Moon in the Guarani language. Natural history. The female holotype (who at the moment of capture carried an eggsac attached to the spinnerets) was found on a fallen trunk, in a dense white tubular retreat, similar to the retreat in the web of A. lagotis. The web lacked the horizontal mesh web described for A. lagotis (Santos and Brescovit, 2001). The juvenile (MACN-Ar 20394) was collected in cracks on a rocky wall over a small water body, no web was observed there. The female illustrated in Fig. 5, was collected in a web, similar to that of A. lagotis, but smaller in proportion to the size of the spider (Gonzalo Rubio, personal communication). Distribution. Known only from rain forest in Misiones province (Fig. 21).Published as part of Piacentini, Luis N., 2011, Three new species and new records in the wolf spider subfamily Sosippinae from Argentina (Araneae: Lycosidae), pp. 27-49 in Zootaxa 3018 on pages 35-38, DOI: 10.5281/zenodo.27863

Agalenocosa grismadoi Piacentini, 2014, sp. nov.
No full textAgalenocosa grismadoi sp. nov. (Figs 8 f, 18, 19, 20, 24f, 27) Type material. Male holotype from Argentina, Santa Fe, Madrejón San Felipe, (probably “Don Felipe”), no collector or date (MACN-Ar 22790), and two female paratypes from Argentina, Buenos Aires province, Tigre, Arroyo Espera, Galiano, M. E., iv. 1983, collected on “camalotes” (MACN-Ar 22778). Etymology. The specific epithet is a patronym in honour of the arachnologist Cristian J. Grismado in recognition of his help in collecting and companionship during many productive field trips in Argentina. Other material examined. PARAGUAY. Alto Paraguay: Pto. Vallemi, Bachmann, A., v.1952, 2 ♀ (MACN- Ar 22711). ARGENTINA. Santa Fe: no further location or collector, viii.1969, 1 ♂ 1 immature (MACN-Ar 22727); no further location, Daguerre, J. B., viii.1969, 1 ♀ (MACN-Ar 22786); no further location or collector, 3. v.1963, 1 ♀ (MACN-Ar 22791); Arroyo del Medio, Rosas, 2. i.1983, 1 ♂ (MACN-Ar 22709). Buenos Aires: Entre río Luján y Paraná de las Palmas, Ferradás, B.R., xii.1983, 1 ♀ (MACN-Ar 22718); Tigre, Viana, J. M., 12. xii.1951, 3 ♂ 12 ♀ 15 immature (MACN-Ar 24011); Delta, Río Sarmiento, Oliva, A., 3. iv.1983, 2 ♂ 1 ♀ (MACN-Ar 22721); Delta, INTA, Carbajal, M., 8. iv.1982, 1 ♀ (MACN-Ar 22728); Berisso, Ferradás, B. R., 1. xii.1982, 1 ♀ (MACN-Ar 22784). Diagnosis. This species can be differentiated from all other currently recognised Agalenocosa species by the small size, domed carapace, in lateral view, instead of straight as in other species of the genus (Figs 18 b, d, 9 b, d) and the presence of 2 -0-0 ventral spines on the tibia I instead of 2 - 2 -0 or 0-2 -0. Males of this species can also be recognised by the absence of the tibial apophysis in the palp (Fig. 8 f), present in the rest of species, and by the ventral process of the embolic division as a sclerotised ridge, more developed in the rest of species (Figs 19 e, 10 c, e). Females can be differentiated by the rounded lightly sclerotised area with sclerotised borders (Fig. 19 a) and the vulvae with small spermathecae (Fig. 19 b). Remarks. The shape of the median and terminal apophyses, and the structure of the embolic division (Figs 20 c,e) suggests the tentative placement of this species in Agalenocosa, despite the lack of the tibial apophysis on the male palp and the shape of the ventral process of the embolic division. The retrolateral side of the male palpal tibia on A. grismadoi sp. nov. is covered with short, stout setae (Figs 20 a, b), more dense on the basal part (Fig. 8 f), this setae resemble to those present on the tibial apophysis of the rest Agalenocosa species (Fig. 3 a). Description. Male. Holotype (MACN-Ar 22790). Carapace with inconspicuous design (Figs 18 d–f). Sternum yellow, sparsely covered with brown bristles, more abundant on the margins. Labium dark grey. Chelicerae lighter than labium, light brown, covered with brown bristles. Dorsum of abdomen brown with a longitudinal wide, pale band with irregular margins, and with spots of whitish glistening setae in the front (Figs 18 d–f). Venter pale brown, slightly darkened at the spinnerets. Legs pale brown with darker annulations, except femora I and II, which are dark brown. Leg formula IV> I> II> III.

Tegulum with a shallow prolateral furrow (Figs 19 c-d, 20 d). Ventral branch of the median apophysis spatula-shaped, dorsal branch beak-shaped, directed retrolaterally (Figs 19 d, 20 c, e). Terminal apophysis short, retrolaterally pointed (Fig. 19 d, 20 c–e). Female. Paratype (MACN-Ar 22778). Colour in ethanol (Figs 18 a–c) as in male.

Remsenornis Piacentini 2017, gen. nov.
No full textRemsenornis gen. nov. Type species: Loxia bonariensis Gmelin, 1789 (traditionally treated as Thraupis bonariensis or, most recently, Pipraiedea bonariensis). Included taxa: Remsenornis bonariensis darwinii (Bonaparte, 1838), R. b. compositus (Zimmer, 1944), R. b. schulzei (Brodkorb, 1938) and R. b. bonariensis (Gmelin, 1789). Diagnosis. The adult male plumage of Remsenornis differs from all other genera of the Thraupidae by the combination of a well-defined blue hood with a bright yellow or orange-yellow rump. It further differs from Pipraeidea, its sister lineage, in all points highlighted above. Etymology. I am happy to name this new genus after James V. "Van" Remsen, Jr., in recognition of his contribution to Neotropical and, especially, South American ornithology. Van has helped form the careers of many ornithologists over the years, but his influence has reached far beyond his formal students, which includes, for example, my views on the curation and care of bird collections. My ideas on generic limits of birds and the meaning and value of monospecific genera also overlap broadly with Van’s, and such ideas are particularly relevant to this paper. Gender: masculine. Remarks. The establishment of a monospecific genus for the Blue-and-yellow Tanager may be questioned on the grounds that monospecific/monotypic genera do not convey information regarding systematic relationships when cited in a linear sequence (or when the species are presented in a book). One of the many flaws of such criticism stems from a misconception of the true goals of a linear sequence, coupled with a limited view of the reasons behind the existence of monospecific genera. It is worth keeping in mind the distinction between mono/ polyspecific (i.e. single/many species) and mono/polytypic (i.e. single/many “forms” [taxa]). First, it should be clear that a linear sequence of taxa is not intended to represent sistership of species (that is left to phylogenies, of course). Linear sequences are a simple and succinct way to present taxonomic diversity in a text. Second, a monospecific genus may result from different processes: (1) the existence of a very distinct lineage/ species that may have undergone strong evolutionary pressures (unlike its sister lineage/species); (2) it may result from extinction(s) of closely related/sister lineages/species; (3) it may reflect our ignorance of the existence of other congeneric species, e.g. Doliornis was treated as a monotypic genus for over a century, until the discovery of a second Doliornis species; (4) it may reflect a temporal trend on the classification of the taxa included in it: for instance, Remsenornis is here defined as a monospecific but polytypic (i.e., with more than one “form”[taxon]) genus which may become polyspecific when any of the subspecies is elevated to species level—a likely fate for R. b. darwinii once adequate data becomes available, and a treatment already adopted by del Hoyo et al. (2016). Some of the points raised above on the significance of monospecific genera were also presented by Isler et al. (2013). In any event, the treatment proposed here is far from being a novelty within the Thraupidae. Currently, there are at least nine other cases of two sister species being treated in two distinct, monospecific genera (following Burns et al. 2016): Orchesticus vs. Parkerthraustes; Sericossypha vs. Compsothraupis; Chlorophanes vs. Iridophanes; Eucometis vs. Trichothraupis; Piezorina vs. Xenospingus; Urothraupis vs. Nephelornis; Spodiornis vs. Acanthidops; Idiopsar vs. Chionodacryon; and Diuca vs. Gubernatrix. The latter pair is even known to hybridize in the wild, which is not the case for Pipraeidea melanonota and Remsenornis bonariensis. Despite the subjectivity of generic limits, the recognition of Remsenornis brings more consistency to classification of the Thraupidae—either the traditional or the one proposed by Burns et al. (2016), which I strongly support. Additional minor adjustments may still be proposed, but I believe we are close to a robust and—hopefully—stable classification of the tanagers.Published as part of Piacentini, Vítor De Q., 2017, A new genus for the Blue-and-yellow Tanager (Aves: Passeriformes): a suggested adjustment to the classification of the Thraupidae, pp. 293-300 in Zootaxa 4276 (2) on pages 298-299, DOI: 10.11646/zootaxa.4276.2.11, http://zenodo.org/record/80615

The scouting project of the Italian basketball federation for female talent selection
No full textAim: Since the early 2000s, the scouting project “Centri Tecnici Federali” (CTF) has represented the largest program for female talent selection of the Italian Basketball Federation, Federazione Italiana Pallacanestro (FIP). The aim of this study was to measure the influence of CTF on players’ selection for the Italian National team between 2007 and 2014. Methods: For this study, 1517 athletes born between 1992 and 2001 were selected. A longitudinal analysis was carried out on their national and international careers, starting with information collected during the CTF scouting (14.39±0.55 y-o). The data was analyzed based on: age, height, duration of CTF selection, duration of transition period between CTF and professional career (PRO), and number of seasons spent in the national championship. Differences between groups were assessed with Chi Square and Student T-test (significant differences were found P<0,05). Results were expressed as percentages, means and SD. Results: The results show that 50% of the athletes reached a national level (NL) championship and 6% reached an international level (IL). Significant differences emerged for every parameter, except for the duration of transition period between CTF and PRO. It is also interesting to note that 90% of the players U22 recruited on the national team in the summer of 2014 have had previous experience with CTF scouting. Conclusion: Beyond strong physical development (1), our study shows how other factors, such as the relevant social context or how old the athlete was when she was scouted, can have a significant effect on the development of a talented athlete (2). In conclusion, our results confirm the importance of CTF for Italian female basketball players for their national and international career.

« Une offrande faite au texte original »: da Trop de chance a Troppa fortuna”
No full textModesto per dimensioni e lunghezza, Trop de chance colpisce il lettore per la potenza del messaggio che veicola e la forza della scrittura dell’autrice. I due aspetti sono in realtà strettamente connessi: se il dialogo ermeneutico che il traduttore intrattiene con il testo – e che lo conduce all’individuazione della intentio operis da cui farà dipendere la sua scommessa interpretativa – crea la base concettuale su cui fondare la riscrittura traduttiva, mostrando il lato “allegorico” della traduzione, nel caso di Trop de Chance, l’equilibrio tra la complessità dei contenuti e la disarmante, strategica semplicità della forma è parso una chiave interpretativa privilegiata di accesso al testo originale. Avendo scelto di “scommettere” sulla forza che viene veicolata con inaspettato vigore dalla sobrietà formale, possiamo affermare che lo studio attento delle scelte sintattiche dominanti nel testo fonte si è rivelato indispensabile affinché si realizzassero quelle condizioni essenziali di rispetto del prototesto che, senza annientare la creatività del testo tradotto, permettono a quest’ultimo di essere concretamente «une offrande faite
