The genus Symmerista Hübner (Notodontidae, Nystaleinae) is reviewed for Costa Rica, based on 49 wild-caught specimens. Four species are newly described: Symmerista luisdiegogomezi Chacón, Symmerista inbioi Chacón, Symmerista minaei Chacón and Symmerista aura Chacón. All are from the cloud forests of the Talamanca moutain range, southern Costa Rica. Photographs of the adults, male and female gen...

We describe Incilius karenlipsae sp. nov., a new species of toad known from a single locality in the Cordillera de Talamanca of central Panama. We describe this species based on a single individual of perhaps what is now an extinct species. We present mitochondrial sequence data from cyt b (675 base-pairs, bp) and 16S (566 bp) to infer its phylogenetic placement among other bufonids. The new sp...

In this paper we study weakly almost periodic and uniformly continuous functionals on the Orlicz Figà-Talamanca Herz algebras associated to a locally compact group. We show that unique invariant mean exists space of functionals. also characterise discrete groups in terms inclusion inside

Mountain environments, characterized by high levels of endemism, are at risk of experiencing significant biodiversity loss due to current trends in global warming. While many acknowledge their importance and vulnerability, these ecosystems still remain poorly studied, particularly for taxa that are difficult to sample such as bats. Aiming to estimate the amount of cryptic diversity among bats o...

A distinctive new species of Atelopus is described from Parque Nacional Chirrip6 Grande, Cordillera de Talamanca (3,400-3,500 m). It closely resembles populations of the Atelopus ignescens complex from the Andes of northern Ecuador and southern Colombia. It differs most significantly from these frogs in the pattern of spiculae and coni development on the throat, chest, hands and feet. The Costa...
