Abstract The stump-tailed porcupine, Coendou rufescens, is a widely distributed but scarcely documented species inhabiting the Andean region of Colombia, Ecuador, Peru, and an isolated population in Bolivia. Despite the wide distribution different aspects on its biology and ecology are still unknown. We present an update to the distribution of C. rufescens, and recent observations on the anatomy, natural history, and conservation in Colombia. For this, we described the male genitalia and present data on reproductive periods, plants used and consumed, and threats. The distribution of C. rufescens comprises 12 ecoregions in an area of 376,225 km2 for the northern group (Colombia, Ecuador, and Peru) and 393 km2 for the southern group (Bolivia). The highest elevational record is in Ecuador (4387 m), being the porcupine inhabiting at highest elevations. The anatomy of the glans is similar to that observed in Coendou quichua and constitutes the second species of Coendou with available information on glans morphology. C. rufescens consumes fruits and leaves of potato cider (Sechium edule: Cucurbitaceae) and woody shrub (Bejaria: Ericacea), and usually perches even in exotic species such as pines. Finally, common treats for the species in Colombia are related to hunting pressures, predation by domestic dogs, and roadkills.

Rollo Howard Beck (1870–1950) was a professional bird collector who spent most of his career on expeditions to the Channel Islands off southern California, the Galápagos Islands, South America, the South Pacific, and the Caribbean. Some of the expeditions lasted as long as ten years during which time he and his wife, Ida, were often working in primitive conditions on sailing vessels or camps set up on shore. Throughout these expeditions, Beck collected specimens for the California Academy of Sciences, the Museum of Vertebrate Zoology at Berkeley (California), the American Museum of Natural History, and the Walter Rothschild Museum at Tring, England. Beck was one of the premier collectors of his time and his contributions were recognized by having 17 taxa named becki in his honor. Of these taxa, Beck collected 15 of the type specimens.

The adult, fourth-stage larvae and the male genitalia of Culex (Culex) apicinus Philippi is redescribed. The pupa is described for the first time. The male genitalia, pupa and fourth-stage larva are illustrated. The available information on the taxonomy and distribution of the species is also included, extending the species distribution in Argentina. Bionomics and distributional data are provided for Culex apicinus.

We live in an unprecedented age for systematics and biodiversity studies. Ongoing global change is leading to a future with reduced species richness and ecosystem function (Pereira, Navarro, & Martins, 2012). Yet, we know more about biodiversity now than at any time in the past. For squamates in particular, we have range maps for all species (Roll et al., 2017), phylogenies containing estimates for all species (Tonini, Beard, Ferreira, Jetz, & Pyron, 2016), and myriad ecological and natural-history datasets for a large percentage of species (Meiri et al., 2013; Mesquita et al., 2016). For neotropical snakes, a recent synthesis of museum specimens and verified localities offers a fine-grained perspective on their ecogeographic distribution in Central and South America, and the Caribbean (Guedes et al., 2018).

ABSTRACT Diplodon granosus was one of the first freshwater mussels to be described for South America. However, the status of the species was confusing for a long time, receiving different taxonomic treatments. In this paper, we redescribe the shell, with new data on the soft parts and information on the distribution and conservation of D. granosus, a rarely recorded species. The shell is thin, not inflated; the macrosculpture is composed only by granules that cover the whole shell, not forming bars; the microsculpture comprises short spikes. In the soft parts we highlight the few, weak and irregularly distributed lamellar connections of the outer demibranch and some features of the stomach, such as the distally enlarged minor typhlosole. There are records of D. granosus over a large area of South America, from Guiana to Argentina. However, most of these records are related to other species and the distribution of D. granosus is restricted to the north of South America in the basins of the Amazonas and Orinoco rivers, and coastal rivers in between. Despite this wide distribution, the species occurs in specific habitats, mainly streams (igarapés), resulting in an extremely fragmented occurrence. Thus, any disturbance to these habitats can threat this freshwater mussel.

Abstract This paper will explore the significance of the expeditions under- taken by Wanda Hanke (1893-1958) in South America, of the networks she established in the region, as well as of her contributions to ethnological studies, in particular her compilation of extensive data and collections. Through Hanke's experience, it is possible to elucidate aspects of the history of ethnology and that of the history of museums in Brazil, as well as to emphasize the status of female participation in these areas. Wanda Hanke spent 25 years of her life studying the indigenous groups of Argentina, Bolivia, Brazil and Paraguay and collecting ethnological objects for natural history museums. Trained in medicine and philosophy, she began to dedicate herself to ethnological studies in her forties, and she travelled alone, an uncommon characteristic among female scientists in the 1940s, in Brazil.
