The glassfrog genus Cochranella, with nine recognized species, is distributed in the lowlands and mid elevation of the Neotropical forests, from Nicaragua to Bolivia (Guayasamin et al. 2009; Twomey et al. 2014). Four species are trans-Andean—C. granulosa (Taylor 1949) occurs in the lowlands and mountains, at mid elevation, of Central America, C. litoralis (Ruiz-Carranza & Lynch 1996) and C. mache Guayasamin & Bonaccorso 2004 occur in the Pacific lowlands and the western cloud forests of Colombia and Ecuador, and C. euknemos (Savage & Starrett 1967) occurs both in Central America and South America (northwestern Colombia).—The other five species have cis-Andean distributions in the Amazonian slopes and lowlands, from Colombia to Bolivia: C. nola Harvey 1996, C. guayasamini Twomey, Delia & Castroviejo-Fisher 2014, C. resplendens (Lynch & Duellman 1973), C. erminea Torres-Gastello, Suárez-Segovia & Cisneros-Heredia 2007, and C. phryxa Aguayo-Vedia & Harvey 2006. In Colombia, C. resplendens is known from the foothills of the Amazon versant in Caquetá (Malambo et al. 2013) and Putumayo (Lynch & Duellman 1973; Ruiz-Carranza et al. 1996). The species is also known from Ecuador (Lynch & Duellman 1973) and Peru (Twomey et al. 2014). Here, we report two new records of Cochranella resplendens, extending the species distribution beyond the Amazonian lowlands into the northern Cordillera Central in Colombia.

Haemagogus (Haemagogus) is restricted mostly to the Neotropical Region, including Central America, South America and islands (Arnell, 1973). Of the 24 recognized species of this subgenus, 15 occur in South America, including the Antilles. However, the centre of distribution of the genus Haemagogus is Central America, where 19 of the 28 species (including four species of the subgenus Conopostegus Zavortink [1972]) occur (Arnell, 1973).

AbstractVespertilionid species are widely distributed in South America. They are highly diverse, with physiological and behavioral adaptations which allow them to extend their distributions into temperate areas. In Patagonia, this family is represented by seven species in three genera (Histiotus, Lasiurus and Myotis). In this study, we analyzed the distribution of two vespertilionid species, Lasiurus villosissimus and Myotis dinellii, including new southernmost records, and their relationship with environmental variables. Two different spatial scales were analyzed: a continental approach for species distribution analyses (South America), and local trapping of bats in northwestern Chubut province, Argentina. We present new southern limits for L. villosissimus and M. dinellii, and included new records for Patagonian bats. The big hoary bat L. villosissimus was recorded as the largest bat inhabiting Patagonia, relating it as a bat mainly inhabiting low, humid and temperate/warm areas. The little yellow bat M. dinellii, instead, is the smallest mammal and the smallest bat recorded in Patagonia to date, related mainly with dry, mid-altitude and temperate/warm areas.

Abstractis a marsupial with unique morphological and ecological characteristics. Owing mainly to its semi-aquatic habits, it is rarely collected by conventional methods, being consequently underrepresented in scientific collections. Its distribution in South America is currently considered disjunct, with a north-west and a south-east portion, and a large gap of more than one thousand kilometers that comprises central Amazonia and a large portion of the Cerrado. On the basis of four museum specimens and two photographed live animals, we present six new records for the species. These records extend the species’ distribution, showing that its range is continuous from southern Amazonia and through Cerrado gallery forests, to the southern portion of its range in southeastern South America.

AbstractXenarthra is an endemic South American lineage of mammals, probably the sister clade of the other placental mammals. The oldest records of Xenarthra are from the latest Paleocene, although its current diversity is much lower than that recorded in some intervals of the Cenozoic Era. A new Neogene Xenarthra (Pilosa and Cingulata) assemblage from two localities of the Argentine Eastern Puna (Calahoyo and Casira) is described. The newly recorded taxa—Cingulata, Dasypodidae, Eutatini: Stenotatus sp. indet. and Eutatini indet., Euphractini: Macrochorobates scalabrinii (Moreno and Mercerat, 1891), and Tardigrada, Mylodontinae: cf. Simomylodon sp. indet. and Simomylodon cf. S. uccasamamensis Saint-André et al., 2010—and those already published from Calahoyo—Cingulata: Macrochorobates chapadmalensis (Ameghino, 1908), Eosclerocalyptus sp. indet., and Tardigrada, Megatheriidae: Pyramiodontherium bergi (Moreno and Mercerat, 1891)—suggest a middle–late Miocene age for the fossil-bearing levels. In Calahoyo, the presence of Stenotatus sp. indet., in addition to some rodents currently under study in the lower levels, suggest a closer similarity with the palaeofauna of Cerdas (southern Bolivia), probably involving the last part of the Miocene Climatic Optimum. The Xenarthra recorded in the middle and upper levels of Calahoyo and Casira suggest a late Miocene–Pliocene age. A comparative analysis between Calahoyo and Casira highlights the absence of Cingulata in the latter and a high diversity in the former. This situation probably indicates different paleoenvironmental conditions. Finally, we present the first certain record of the genus Simomylodon Saint-André et al., 2010 in Argentina, which includes the oldest record of dermal ossicles for sloths in South America.

New World species of the genus Incisitermes Krishna, 1961 range from California to Peru.  The soldier of this genus is notable for the incised anterior margin of the pronotum and the elongated third antennal article.  I report the broad occurrence of Incisitermes platycephalus (Light, 1933) from extreme southern Mexico to the Pacific coast of Nicaragua. Incisitermes nigritus (Snyder, 1946) from Guatemala is a junior synonym of I. platycephalus.  Among Incisitermes, I.  platycephalus is characterized by its small size, dark imago, and dorsoventrally compressed soldier head capsule.

Riparian Habitats

Passiflorariparia was incompletely described by Masters, who cited specimens of Martius and Spruce. While Spruce 2191, the unique syntype with an observable corona, exhibits a reduced outermost series of filaments, the accompanying iconography represents two equal outer series. Later descriptions have neither added significant information nor corrected the inconsistency in the corona description, so that four closely related species have been distinguished on the basis of traits not properly documented for P.riparia: P.emiliae (unequal outer series of filaments), P.crenata (bract color), P.pergrandis (flower size and sepal awn length), and P.fernandezii (hypanthium pubescence and shape). The present study compares (i) the descriptions of the above-mentioned taxa and (ii) 43 associated vouchers, as well as live specimens from two associated P.crenata populations. These and other specimens were georeferenced for a comparison of their distribution and habitat. Of the five P.riparia descriptions found in floras, only that of the Flora of Ecuador appears clearly divergent, corresponding in fact to P.tolimana. Those of the four other taxa only differ by unequal corona filaments (except for P.crenata) and the pubescence of floral parts. However, 22 vouchers associated with all these descriptions (including 16 for P.riparia), as well as the live specimens, share both these traits; the other 21 vouchers were uninformative and/or could not be assigned to any of the five species. The wider sample of 62 specimens indicates no significant differences in either geographic or in climatic distribution (lowlands of the Amazon basin), and a marked preference for riparian habitats. Thus, their very close morphology and ecology justify the placement of P.emiliae, P.crenata, P.pergrandis and P.fernandezii as synonyms of P.riparia, designating Spruce 2191 as epitype. The most similar species, P.ambigua (20 specimens mapped), differs in corolla and bract color, as well as a distribution centered along the tropical Andes of South America and in Central America, in more diverse habitats.

Seventeen species of pelagic Polychaeta from the northeastern Pacific are recorded. Of these, five (Sphaerosyllis pirifera Claparède, Dorvillea kefersteini McIntosh, Spiophanes cirrata Sars, Magelona sp., and Flabelligera affinis Sars) are species which, whilst not exclusively pelagic, are known to swim at some stage, particularly as larvae. One record (Pedinosoma curtum Reibisch) is new to the Pacific Ocean, two (Pontodora pelagica Greef and Callisona nasuta Greef) are new to the northeastern Pacific region, and four (Pelagobia longicirrata Greef, Lopadorhynchus uncinatus Fauvel, Sagitella kowalewskii Wagner, and Callizona angelini (Kinberg)) are records of northerly extensions of distribution. The first observation of a larval Cossura (probably of C. longocirrata Webster and Benedict) is recorded. Poeobius meseres Heath is recorded from a number of stations and the classification of Poeobiidae is discussed.Eight species of Siphonophora are listed, all of which constitute new records for the region covered by the present collections. Six species of Mollusca, comprising five Pteropoda and one Heteropoda, are recorded, none of which have been identified previously in northeastern Pacific plankton. Three of the genera of Pteropoda (Anopsia, Thliptodon, and Cliopsis) are characteristic of warmer seas, the other two, and the heteropod, are widely distributed. Of the two species of Tunicata listed one is new to the northeastern Pacific.
