Se estudia la caracterización limnológica de 30 lagunas del bosque tropical seco de Costa Rica y Nicaragua durante 2010-11. Se aislaron gémulas de esponjas de agua dulce en cuatro de las localidades. Se registraron dos nuevas citas de esponjas para Nicaragua, Radiospongilla cerebellata (Bowerbank, 1863) y Corvoheteromeyenia heterosclera (Ezcurra de Drago, 1974). En Costa Rica también se registró esta última y se recolectaron ejemplares de Radiospongilla crateriformis (Potts, 1882). En otra laguna de Costa Rica, se recolectó una larva neuróptero (Insecta) de la familia Sisyridae asociada a las esponjas: Sisyra apicalis Banks, 1908. Por otro lado, hemos podido recolectar gémulas incrustadas en el tubo de alojamiento del oligoqueto Aulophorus vagus Leidy, 1880 (Annelida: Oligochaeta: Naididae), que también supone la primera cita para Costa Rica y Nicaragua. The characterization of 30 temporary ponds was done in the tropical dry forest of Costa Rica and Nicaragua, in 2010-2011. Gemmules of sponges were isolated in four of the studied sites. Two new records were set for Nicaragua, Radiospongilla cerebellata (Bowerbank, 1863) and Corvoheteromeyenia heterosclera (Ezcurra de Drago, 1974). In Costa Rica, the last ones was also recorded as well as specimens of Radiospongilla crateriformis (Potts, 1882) were collected. In another pond of Costa Rica, larva of Neuroptera (Insecta) belonging to family Sisyridae, commonly associated to sponges, was collected: Sisyra apicalis Banks, 1908. In addition, we have been able to collect embedded gemmules in the housing tube of the annelid Aulophorus vagus Leidy, 1880 (Annelida: Oligochaeta: Naididae). This species is also here reported for the first time in Costa Rica and Nicaragua.

We report 19 species of Myxomycetes for first time in Peru. Macbrideola spinispora L.M. Walker, G. Moreno & S.L. Stephenson, previously known only from the type collection from Costa Rica, is now reported for South America, enlarging its distribution considerably. The Myxomycetes were collected in Wayqecha Biological Station, a conservation area in the Cuzco region. The specimens were deposited in the South Peruvian Herbarium (HSP) and the Real Jardín Botánico de Madrid (MA-Fungi).

Material of several collections was reviewed, using original descriptions and keys, and comparing with the type material. Twenty-five species of the genus Brachiacantha were found in Central American material, including nine new species: B. nubes Nestor-Arriola, Toledo-Hernández and Solís, sp. nov., B. dentata Nestor-Arriola, Toledo-Hernández and Solís, sp. nov., B. isthmena Nestor-Arriola, Toledo-Hernández and Solís, sp. nov., B. aurantiapleura Nestor-Arriola, Solís and Toledo-Hernández, sp. nov., B. invertita Nestor-Arriola, Toledo-Hernández and Solís, sp. nov., B. papiliona Nestor-Arriola, Toledo-Hernández and Solís, sp. nov., B. tica Nestor-Arriola, Toledo-Hernández and Solís, sp. nov., B. hexaspina González, Větrovec and Nestor-Arriola, sp. nov., and B. mimica Nestor-Arriola and Toledo-Hernández, sp. nov.

ABSTRACTAcross the globe, primate species and habitats are threatened by human activity. This is especially true for species found in tropical dry forests, which are widely distributed and comprise diverse habitats that remain largely unprotected. Evidence suggests that some primate species endemic to tropical dry forests may be more sensitive to anthropogenic disturbance than others, but our ability to predict primate abundance in the face of disturbance also depends on the specific variables for each site. Here, we consider the factors that explain the high density of white-faced capuchins (Cebus capucinus) found in the Taboga Forest, Costa Rica, a relatively small fragment of tropical dry forest surrounded by agricultural fields. Our analyses suggest that, for capuchins (and potentially for mantled howler monkeys, Alouatta palliata), the size and disturbance of a forest fragment may matter less than the composition and availability of key resources, like above-ground water. Group sightings for both species were higher near permanent water sources, but group sightings did not vary between edge and interior forest. These findings help explain why some primate species can flourish even alongside anthropogenic disturbance and thus carry important implications for conservation efforts. Smaller forest fragments, like Taboga, may be able to support high densities of some species because they provide a mosaic of habitats and key resources that buffer adverse ecological conditions. Future studies will assess the extent to which primates in the Taboga Forest rely on the canals versus the river and will consider how the high density of capuchins in Taboga influences ranging patterns, home range overlap, and the frequency and intensity of intergroup encounters.RESEARCH HIGHLIGHTSHere we introduce a new white-faced capuchin study site in the Taboga Forest, Costa Rica, a fragmented tropical dry forest.Forest fragments like Taboga may support high primate densities because they provide a mosaic of habitats and key resources.

Epiphytic Bromeliads

A survey of the camerobiid mites living on epiphytic bromeliads and the forest floor of a Mexican tropical dry forest was carried out. We found three new species of the genus Neophyllobius, which are described in this paper; the first two, namely N. cibyci sp. nov. and N. tepoztlanensis sp. nov., were both found inhabiting bromeliads (Tillandsia spp.) and living on two tree species (Quercus obtusata and Sapium macrocarpum); the third, N. tescalicola sp. nov., was found in soil and litter under Q. obtusata. These three new species can be differentiated from other species in the genus by a combination of morphological characters in adult females, mainly those setae on femora and genua I. The idiosoma and leg setal ontogeny of a camerobiid mite is presented for the first time in this paper, illustrating chaetotaxic notations and their relative positions in N. cibyci sp. nov. larva, protonymph and adults (female and male), and establishing setal homologies among instars. Setal homology with other species in the cohort Raphignathina is briefly discussed. Additionally, a compilation and an identification key to all known species of camerobiid mites in Mexico is provided.
