Increasing Temperature

Increasing temperature and changing land-use in the Guayana Shield and Amazonia result in an accelerated decline of sensitive lichen populations. Monitoring of these populations by biological plot inventories in particularly vulnerable sites is urgently needed. In order to know the diversity and distribution of lichen species at the Alto Orinoco, Parque Nacional Duida-Marahuaca and nearby areas from Amazonas state, Venezuela, lichens were sampled during four expeditions in more than 40 plots located from 200 m (premontane forest) to more than 1500 m elevation (altotepuyana vegetation). Additional data were obtained from literature and herbaria. Our assessment, although incomplete, revealed 205 described species, 150 undescribed species, 84 genera and 27 families. Among the described species 162 were observed in the basimontane vegetation, 38 in the montane vegetation, 24 in the altotepuyana vegetation, while 20 appear to be endemic to the study area. Sixty-nine species are new records for the Cerro Duida. A checklist with taxonomic and ecological data is presented. Five new species and one new variety are described: Cladonia duidana V.Marcano & A.Morales sp. nov. (Cladoniaceae), Pertusaria orinoquensis V.Marcano sp. nov., Sticta kunuhana V.Marcano sp. nov. (Lobariaceae), S. spruceana V.Marcano sp. nov. (Lobariaceae), Xanthoparmelia esmeraldensis V.Marcano & A.Morales sp. nov. (Parmeliaceae), and Lepraria arbuscula (Nyl.) Lendemer & Hodk. var. fumarprotocetrarica V.Marcano var. nov.

A New Species

The examination of a collection of nudibranchs (Mollusca: Gastropoda: Heterobranchia) obtained during several expeditions to international waters off Newfoundland, North Atlantic, revealed the presence of rare species, new records for the area, and an undescribed species ofTritonia(described herein). This includes the first record ofDendronotus niveusEkimova, Korshunova, Schepetov, Neretina, Sanamyan and Martynov, 2015 from the Atlantic Ocean and numerous specimens of the rare speciesDoridoxa ingolfianaBergh, 1899, which is here redescribed. Other species collected areFlabellinacf.salmonacea(Couthouy, 1838),Dendronotus frondosus(Ascanius, 1774),Dendronotus robustusA. E. Verrill, 1870,Aldisa zetlandica(Alder & Hancock, 1854),Onchidoris bilamellata(Linnaeus, 1767),Colga villosa(Odhner, 1907) as well as an unidentified species ofAeolidiella. Anatomical characteristics and genetic barcode data are used to identify the species whenever it was possible. Ecological data, including substrate, associated fauna and bathymetric range are provided.

Ecological Data

Increasing temperatures and changing land-use in the Venezuelan Andes result in an accelerated decline of sensitive lichen populations. Monitoring of these populations by biological plot inventories in particularly vulnerable sites is urgently needed. In order to know the diversity and distribution of lichen species occurring in the paramos El Batallón and La Negra, General Juan Pablo Peñaloza National Park, in the Venezuelan Andes, we carried out various collections along an altitudinal gradient including montane forest (2100–3000 m) and paramo vegetation (3200–3650 m). The results showed a total of 104 species and 40 genera, 44 species from the montane forest, 82 species from the paramo, six new records for Venezuela, and 31 new records for the southwest of the Venezuelan Andes (Táchira State). A checklist with taxonomic, morphological and ecological data is provided for the most relevant species. Bunodophoron portachuelense V. Marcano & L. Castillo (Sphaeorophoraceae) is described from the paramo. Increasing forestry exploitation, livestock and cultivation during decades from the montane forest would explain the highest diversity found in the paramo.

The subfamily Acastinae contains a diverse group of barnacles that are obligate symbionts of sponges and alcyonacean and antipatharian corals. Integrating morphological and genetic (COI) data to compare against known species, this paper reports on nine species of sponge-inhabiting barnacles of the subfamily Acastinae, including three undescribed species (Acasta caveata sp. nov., Euacasta acutaflava sp. nov., and E. excoriatrix sp. nov.) and three species previously not recorded in Australian waters (A. sandwichi, Pectinoacasta cancellorum, and P. sculpturata). The new species are distinguished from similar species by a suite of morphological characters as well as genetic distances. A lectotype for Pectinoacasta cancellorum is designated. Sponge hosts were identified for all specimens where possible and are represented by 19 species from eight families and five orders.

Immature stages of many Brazilian Smicridea species remains unknown, and efforts to describe all life stages are required. In this paper, the larva and pupa of Smicridea (Rhyacophylax) gladiator Flint 1978, associated with adults through the metamorphotype method, are described and illustrated. In addition, the known distribution of this species is extended in the Brazilian Amazon Basin with new records from Amazonas state and the first record in Pará state. Information about its bionomics is also provided.

ABSTRACT Peperomia is the second most diverse genus of Piperaceae, with an estimated 1,600 species and a pantropical distribution. This work aims to present a taxonomic synopsis of the genus in the State of Roraima, in the extreme north of the Brazilian Amazon forest and belonging to the central-south portion of the Guayana Shield. Based on collecting expeditions and analysis of specimens in various herbaria, 23 taxa were recognized, with two new records for the State and one of them, a new record for Brazil. The taxa are differentiated mainly by phyllotaxis, shape and size of their leaves, in addition to habit and fruits. They have been found in areas of lowland, submontane, montane, tepui and floodplain (várzea) forests and mostly show a distribution restricted to the Neotropics. Some species in the state are presently known exclusively from Mount Roraima, and restricted to a few specimens.

ABSTRACT The South American genus Heteropyge Silvestri, 1897 is revised, accommodating now six accepted species. Adults of the poorly known species Heteropyge araguayensis (Schubart, 1947) are described for the first time from near-topotypic material collected near the Araguaia River, state of Mato Grosso, Brazil. In addition, based on recent samplings and on material from Schubart’s collection, H. bidens (Schubart, 1945) is removed from the synonymy of H. cayennophilus (Silvestri, 1897) and revalidated. Both species show significant differences concerning the gonopods and male leg-pair 1. New records and additional data for H. bidens and H. cayennophilus are provided, as well as an updated checklist of the species belonging to Heteropyge.

ABSTRACT Spiders of the genus Loxosceles, commonly known as brown recluse spiders, can cause serious accidents in humans. Their venom has a powerful proteolytic and hemolytic action. Each year these spiders are the cause of a great number of araneism in Brazil. This work presents new records of Loxosceles amazonica for the municipal districts of Manaus and Iranduba, Amazonas, Brazil.

We report new records of the White-Tailed Deer (Odocoileus virginianus) in Brazil based on specimens deposited in scientific collections. These new records expand the known geographic distribution of the species in Brazil southwards in the states of Roraima and Amapá, the latter the first record of the species below the equator line in Brazil, and register it for the first time in the state of Amazonas. These records contribute to increase the knowledge of the geographical distribution of O. virginianus in Brazil and highlights the importance of museum collections as a source of biogeographic and ecological data.
