The diversity of avian nasal mites has been incompletely studied in South America and most reports have been made on the fauna of Brazil, especially from the 1940s to 1970s. Recently, the development of new research has contributed records of species not previously reported in the country. As a result, a compilation of records of nasal mites (Astigmata: Cytoditidae, Turbinoptidae; Prostigmata: Ereynetidae; Mesostigmata: Rhinonyssidae) of birds in Brazil is presented. One hundred and twenty-four species of nasal mites were recorded parasitizing 168 bird species. The Rhinonyssidae was the family with the highest number of mites reported (108 species). Most nasal mite hosts in Brazil are native birds, however, mites have also been reported parasitizing captive exotic birds, as well as introduced species and domesticated birds.

This article discusses the inclusion of domestic chicken (Gallus gallus domesticus, Linnaeus 1758) and other exotic bird species as part of the knowledge and practices related to birds (an ethnoornithology) among the Karitiana, a Tupi-Arikém-speaking indigenous people in the northern part of the state of Rondônia, in the southwestern Brazilian Amazon . Chickens are believed to have been introduced to the Amazon basin after contact with non-indigenous population, although this claim is controversial . They were initially associated with certain native birds . However, certain remarkable characteristics of these birds soon sparked reflection through which the species was gradually distinguished from the birds of the forest . These reflections influence how the Karitiana currently relate to chickens, which includes raising them in the villages, a practice encouraged by public policies related to food production, security, and sovereignty .

A fragmentary specimen of pterosaur originally assigned to the genus Pterodaustro Bonaparte, 1970 is reassessed. The presence of a sagittal dorsal cranial crest on a fragment of nasopreorbital arcade with linear vertical trabeculae and the occurrence of alveolar protuberances on the os dentale indicate the new specimen has similarities with crested pterodactyloid pterosaurs of the family Ctenochasmatidae, and with members of the Dsungaripteridae. The presence of alveolar protuberances allows us to assign the specimen to the Dsungaripteridae. It forms the basis of a new genus and species, Domeykodactylus ceciliae.

Lizards of the family Diploglossidae occur in moist, tropical forests of Middle America, South America, and Caribbean islands. Our analyses based on new molecular and morphological data indicate that the widely distributed genera Celestus Gray, 1839 and Diploglossus Wiegmann, 1834 are paraphyletic. We restrict the former to Caribbean islands and the latter to South America and Caribbean islands. We assign species in Middle America, formerly placed in Celestus and Diploglossus, to Advenus gen. nov., Mesoamericus gen. nov., and Siderolamprus Cope, 1861. We assign species on Caribbean islands, formerly placed in Celestus, to Caribicus gen. nov., Comptus gen. nov., Celestus, Panolopus Cope, 1862, Sauresia Gray, 1852, and Wetmorena Cochran, 1927. Our phylogenetic tree supports three major clades in the family: Celestinae subfam. nov. (Advenus gen. nov., Caribicus gen. nov., Comptus gen. nov., Celestus, Panolopus, Sauresia, and Wetmorena), Diploglossinae (Diploglossus and Ophiodes Wagler, 1828), and Siderolamprinae subfam. nov. (Mesoamericus gen. nov. and Siderolamprus). Our timetree indicates that the diploglossid lineage originated in the early Cenozoic and established three major centers of diversification in the Americas: Middle America (siderolamprines and one celestine), South America (diploglossines), and Caribbean islands (celestines and diploglossines). The majority of threatened species are on Caribbean islands, with the major threats being deforestation and predation by the introduced mongoose. Molecular and morphological data indicate that there are many undescribed species in this family of lizards.

Comparative Treatment

Abstract This article proposes a detailed comparative treatment of negation in the Jodï-Sáliban language family (Venezuela-Colombia, Northwest Amazonia, South America), which consists of four languages: Jodï [yau], Sáliba [slc], Piaroa [pid] and Mako [wpc]. This comparative analysis of negation strategies across the four languages in the family not only offers an overview of negation strategies in this language family but also allows for conclusions to be drawn on the cognacy of the different constructions and markers as well as on the sources of the main negation strategies. Specifically, I show that, even though certain markers are not cognate, negation in these languages has – as far back as the documentation goes – always been postverbal and suggest that postverbal negation can be diachronically stable. This research thus offers an in-depth analysis of negation in Jodï-Sáliban, a language family that remains underdescribed, and, crucially, contributes to our understanding of postverbal negation and its sources.

Structured Approach

PurposeThe authors identify the theoretical constructions measuring the intentions to pursue succession as well as the socioemotional wealth theoretical framework, and the authors propose an objective of testing the relationships existing between them so as their importance giving evidence of their relevance.Design/methodology/approachIt is a research with a positivist philosophical position measuring in a quantitative way with a deductive and structured approach applied to 98 CEO owners of Mexican companies, using nonparametric methodologies the authors simulated subsamples with structural equation modeling in SmartPLS 3.3.2, the metrics on the model are described as a functionalist paradigm.FindingsDirectors' attitudes paired up with the intentions of succession are significantly related to the socioemotional aspect of the family business; although the theory proposes three aspects to measure these intentions, the social norm in this research has not been strong enough to be a predictor as an influence on the company's socioemotional wealth.Originality/valueThe authors found this a valuable paper for the complement of theory focused on purely manifesting aspects in family companies, because they identified theoretical and empirical relationships opening up guidelines for new research in socioemotional aspects in accordance with the entrepreneurs attitudes to achieve succession, the differentiation lies in measuring psychological aspects of the director's behavior toward succession and not to the succession per se as done in most research; also, the methodology of data analysis facilitates the reader to easily recognize the relationships between the proposed theoretical constructions, showing the detailed metrics development by researchers in the family business field.

The coccidian Caryospora bigenetica was first described in the snake Crotalus horridus (Viperidae) from United States of America. This study represents the first record of the occurrence of C. bigenetica in snakes in South America. Feces were sampled between November 2013 and May 2014 from 256 wild snakes maintained in scientific breeding facilities in the states of Mato Grosso do Sul (MS; n = 214) and Rio de Janeiro (RJ; n = 42), Brazil. Caryospora bigenetica was found in 14 (5.6%) snakes, all belonging to the family Viperidae. Ten Bothrops moojeni and two Crotalus durissus from MS were infected. The coccidian was also found in one C. durissus and in one Bothrops jararacussu from the state of RJ. The oocysts were spherical with a double wall, the exterior lightly mammillated, striations apparent in transverse view, 13.0 µm (12 – 14); polar granule fixed in the internal wall. Sporocysts oval or pyriform, 10.0 × 8.0 µm (9 – 11 × 8 – 9); Stieda body discoid; sub-Stieda body present; sporocyst residuum present, formed by a group of spheroid bodies between sporozoites. This study increases the number of viperid hosts of C. bigenetica and expands the geographical distribution to South America.

We examined 308 specimens of the Indo-Pacific blenniid Omobranchus punctatus deposited in four museum collections, and analyzed data on their collection locations to assess its invasion on the Atlantic coast of Central and South America. This species occurs in shoreline estuarine and marine habitats in the Indo-West Pacific. Previous sampling and recent records in the Tropical West Atlantic from 1930 to 2004 produced 20 records for: Panamá, Colombia, Venezuela, Trinidad and Brazil. In this work, we provide data on 17 new records for the Gulfs of Venezuela and Paria in Venezuela, as well as four records for Maranhão and Pará states in NE Brazil. The temporal pattern of collections (1930 - 2009) and the proximity of most localities to ports and zones of ship traffic indicate that O. punctatus was initially introduced to the Atlantic by ships travelling from India to Trinidad. Within Brazil the introduction is linked to shipping connected to petroleum platforms. In Maranhão and Pará the introduction may have occurred as a result of fish sheltering in fouling on hulls of ships moving between ports around the mouth of the Amazon River. Alternatively, the spread of this species along of the American coast may reflect the expansion of the range of O. puntactus through larval dispersal in northward flowing currents. We recommend monitoring of this introduced species, and studies of its ecology in West Atlantic areas.

Frederick Robert Miller, who died on 11 November 1967, was born on 2 May 1881, in Toronto, Canada. His paternal grandfather, Captain John Miller, of Bermuda, was co-owner of the brig Demerara which he sailed many times between Liverpool and the West Indies and South America. Following a mutiny on board his ship, Captain Miller was persuaded by his wife to leave the sea. They settled for a time in Dublin, Ireland, where they had a son, Allan Frederick Miller. The family later emigrated to Toronto, Canada, where Mr Allan Miller eventually became Secretary-Treasurer of the Toronto General Hospital, a position which he held for many years.

Size And Structure

A new argyrolagoid marsupial, Hondalagus altiplanensis n. gen., n. sp., from the middle Miocene (Santacrucian–Friasian) age locality of Quebrada Honda in southernmost Bolivia represents the smallest and most specialized member of the family Argyrolagidae known. The lower molars are hypselodont and lack vertical grooves labially and lingually, and M4 is greatly reduced relative to M3. In overall size and structure, H. altiplanensis compares best with Microtragulus catamarcensis (Kraglievich, 1931) from rocks of late Miocene (Huayquerian) age in northwest Argentina. Hondalagus altiplanensis demonstrates that the adaptive radiation of argyrolagoids was much greater than previously envisioned, and that generic differentiation of known taxa occurred no later than early–middle Miocene time in South America.
