Abstract:

AbstractWe document the first records for Guyana of Roraiman Antbird (Percnostola [Schistocichla] “leucostigma” saturata), an endemic of the tepui highlands of southeastern Venezuela, northern Brazil and western Guyana. This form is well differentiated from nominate leucostigma (Spot-winged Antbird) of the Guianan lowlands in morphology, vocalizations, and genetics, and replaces it both altitudinally and ecologically. The two taxa are distributed parapatrically on the continuously forested northeastern slopes of the eastern tepuis, and they almost certainly come into contact, yet there is no evidence of intermediacy. We recommend that saturata be treated as a distinct species of Percnostola, and consider its' origin in the light of various models of speciation in the tepuis.Especiación de Aves en el Pantepui: El Caso de Percnostola (Schistocichla) “leucostigma” saturataResumen. En este trabajo documentamos los primeros registros para Guyana de Percnostola (Schistocichla) “leucostigma” saturata, un hormiguero endémico de las montañas del sureste de Venezuela, norte de Brazil y oeste de Guyana. Esta forma se diferencia notablemente en morfología, vocalizaciones y genética de P. l. leucostigma, presente en las tierras bajas de las Guyanas, y la reemplaza altitudinal y ecológicamente. Los dos taxa tienen distribuciones parapátricas en los bosques continuos de las laderas noreste de los tepuis del este, y casi con seguridad están en contacto, aunque no hay señales de hibridización. Recomendamos que saturata sea tratada como una especie distinta de Percnostola, y discutimos su origen considerando varios modelos de especiación en los tepuis.

Abstract:

The myrmicine ant genus Rogeria in Guyana is reviewed. Using previously published records, older collections, and collections from recent leaf litter ant survey work, nine Rogeria species are now known from Guyana, with another two species that probably also occur in Guyana. Among these eleven species, a new species, R. tsumani, is here described, and four of them, including the new species, are new records for Guyana. A key to the species found in Guyana is provided, along with illustrations of all 11 species.

Abstract:

An examination of the available literature shows that a total of 1,205 butterfly species from 457 genera, 22 subfamilies and six families have been recorded in Guyana. Specimens that are unidentified above genus level and those that require further verification are excluded from this checklist. Although investigations have been conducted in all of the natural regions and administrative regions of Guyana, additional research is required on a number of aspects including species biology and behavioral ecology. It is hoped that this list will facilitate research on such data gaps.

Abstract:

A relative of the African species described by Brotherus as Bryum perspinidens, has been discovered in Guyana with erect capsules and a short inner peristome. The Guyana material is recognized as a new species, and both species are placed in the genus Brachymenium. The characteristics that distinquish the genus are discussed with reference to the Guyana specimens of Brachymenium speciosum.

Abstract:

A new species of Charinus Simon, 1892 is described from French Guyana, raising the number of species in the genus to48 (27 for the Neotropical region and 19 for South America). Charinus bromeliaea sp. n. is distinguished from the otherspecies in the genus by morphological characteristics and unique ecology. Adapted to live in Achmea bromeliads on gran-ite inselbergs, this species is an interesting addition to the wide range of habitats Charinus species are found in. This is also the first record of the genus from French Guyana and this record extends the geographic distribution of the genus.

Abstract:

Using stable nitrogen and carbon isotope signatures, we investigated the trophic ecology and identified potential prey fish groups supporting the giant Arapaima within floodplain lakes of the Essequibo River basin in southwestern Guyana. Morphological descriptions of feeding structures and digestive tract are presented together with preliminary data on Arapaima diets. Stable isotope results suggest that algivorous/detritivorous and omnivorous fishes contributed most to Arapaima biomass, and generally, that was consistent with what is known about Arapaima diets. Stable nitrogen isotope ratios for piscivorous fishes in these lakes were higher than nitrogen isotope ratios for Arapaima, indicating that piscivorous fishes are unlikely to constitute a major source of energy for Arapaima. This population of Arapaima has an intestine averaging 1.45 times total body length, relatively small teeth, and numerous, closely-spaced gill rakers. These morphological features, together with isotope data, support our inference that Arapaima are secondary consumers and may be better characterized as omnivores and not top predators.
