Cyathea pungens, a widespread Neotropical scaly tree fern, is reassessed taxonomically. Based on extensive field observations in South America and the Caribbean, and comparative studies of herbarium specimens and online resources, we define C. pungens as a mainly Amazonian species that extends into the Caribbean but neither beyond west of the Andes...

A new species of Cyathea is described for Peru and Ecuador. The new species differs from congeners by a combination of traits including glabrescent and scurfless mature axes abaxially, concolorous orange-brown petiole scales, winged costae, and lack of indusium. It is illustrated and compared to similar species, and its biogeography is discussed.

The Amotape-Huancabamba Zone, straddling the Huancabamba Depression in the tropical Andes, is often recognized as a major hotspot of species richness for plants and animals in the Neotropics. The biogeographic role of the area as a barrier, transition, or unique endemism zone in the Andes has long been debated. Here, using tree ferns, we take a new...

We present an update to our knowledge of the taxonomically challenging Cyathea multiflora-group. Several taxa can be reinstated and newly described thanks to extensive field studies in Colombia and bordering countries. Easily overlooked characters like minute hairs, laminar squamules, and size of indusia correlate with distinct physiognomies in the...

On the basis of recent fieldwork, six new species of Cyathea from northern Peru are described: Cyathea carolinae, C. cisandina, C. grata, C. oscarorum, C. phoenix, and C. novoi. All were found on sandstone subtrates under different precipitation regimes. Here, we illustrate these species, discuss their natural history, compare them to their putativ...

Based on recent collections, we describe a new species of scaly tree fern, Cyathea giraldoi, from northern Colombia and discuss its ecology. The new species differs from putative close relatives by a character combination including a small size, often decumbent trunk, strongly arching fronds with drooping tips, nearly triangular lamina, thick scurf...

On the basis of field and herbarium work, 11 species of Cyathea from Peru are described as new. Cyathea angelica, C. hierbabuena, C. pibyae, C. recondita, C. xerica, and C. yambrasensis come from the headwaters of the Marañón river in northern Peru, and C. estevesorum, C. lehnertii, C. monteagudoi, C. rocioae, and C. valliciergoana from the eastern...

Three new species of Cyathea Sm. are described and illustrated from Colombia. Cyathea antioquiensis differs from C. latevagans by its rhizome scales with a narrower pale margin, stipe and rachis with scurf and sessile linear-oblong pinnae. Cyathea incognita differs from C. gracilis by its terrestrial habit, thinner rhizome, rhizome scales with a br...

Three species of the genus Cyathea from the sandstone areas of the Amotape-Huancabamba zone are described as new to science: Cyathea abrapatriciana and C. oreopteroides from northern Peru and C. chimaera from southern Ecuador. They are illustrated and discussed regarding their biogeography and putative relationships..

This note reports Peter’s ghost faced bat Mormoops megalophylla from the island of Barbuda, northern Lesser Antilles. Our record is based on fossil remains recently discovered in uncatalogued material or misidentified specimens within a late Quaternary assemblage collected at Caves 1 and 2, Two-Foot Bay, Barbuda, over 50 years ago and housed at the...

We present evidence that the name Natalus espiritosantensis (Ruschi, 1951 ) is not the oldest available name for the single species of Natalus occurring in South America south of the Amazon River. The oldest name available, Spectrellum macrourum (Gervais, 1856), has priority over Myotis espiritosantensis (Ruschi, 1951 ) and is restored based on Ger...

Here we report a right dentary of Peter's ghost-faced bat Mormoops megalophylla from an archeological site in northern Matanzas province, western Cuba. The specimen was excavated from a pre-Columbian archeological cave deposit in association with stone tools, bivalve shells, snake and fish vertebrae, and capromyid (rodent) postcranial elements. Alt...

For much of the last third of the 20th century, the diversity of funnel-eared bats (family Natalidae) was underestimated. Although as many as four genera and 11 species were recognized by the mid 20th century, by the 1980s the family was traditionally listed as comprising a single genus of four or five species. In the past decade, the taxonomy of N...

Durante décadas, la taxonomía del género Natalus en las Antillas Mayores ha sido controvertida. A pesar de que tres taxa han sido descritos para Natalus (sensu stricto) en las Antillas Mayores, la controversia se ha concentrado en la validez de Natalus major (supuestamente distribuida en Cuba, La Española y Jamaica) como especie distinta de Natalus...

The name Natalus stramineus has been historically applied to populations of the genus Natalus from virtually the entire Neotropics. The geographic origin of the holotype of N. stramineus, however, has never been known with certainty, confounding discussions concerning the species limits, nomenclature, and biogeography of this genus. The type locali...

Pygoderma bilabiatum is a medium-sized short-faced stenodermatine bat (Chiroptera: Phyllostomidae) with prominent doughnut-shaped glandular tissue masses surrounding the eyes, among other distinctive characters. In this paper, we describe gross external morphology of newly discovered swellings of Pygoderma, probably enclosing glandular tissue found...

strong>Abstract Reviewing available information from published literature, museum database, personal communications and from the authors own field data, the conservation status of Cuban bats has been assessed using six qualitative parameters: abundance, distribution, roosting habits, aggregation level, forest dependence, and degree of endemism. Th...

A new species in the genus Natalus is described on the basis of 71 specimens found in museum collections. The body pelage of the new bat is unique among natalids in having hair bases much darker than hair tips. This new species is also characterized by short tibiae, legs and feet notably hairy, a long braincase, and a shallow rostrum. This species...

Hot caves are important refuges for the endemic West Indian bat fauna, comprising altogether more than 60% of the native mammal fauna of the region. Nonetheless, our knowledge of the distribution of such caves and the diversity of their resident bat communities is very incomplete as a result of infrequent and largely limited bat surveys. The limite...

The sole Cuban representative of the bat genus Natalus, described as a fossil in 1919, was rediscovered in 1992 as an extant colony in a cave in the western tip of the island. Other extant Greater Antillean populations of this genus were known before from Jamaica and Hispaniola and, together with the fossil Natalus from Cuba, were considered synony...
