Pternopetalum paucifoliolatum, a new species from Sixigou Scenic Area, Emeishan City, Sichuan Province, is proposed and described. Diagnostic morphological characters, full description, detailed illustrations, and a distribution map are provided. The new species is similar to P. porphyronotum in possessing the 1-pinnate leaves and the abaxially purple-red leaflets, but differs from the latter by shorter stature, fewer leaflets ((1–) 3–7) and rays (5–8), the leaflet margin white-ciliate. The new species, which is assessed as Critically Endangered (CR), was only found on limestone cliffs. We also provide a new key to the species of Pternopetalum.

A New Species

Aiphanes argos is a new species of palm segregated from Aiphanes parvifolia, which is now recognized to be a species complex. Aiphanes argos is one of the few rheophytic members of the palm family, and is endemic to a small area in the Samaná Norte River canyon in Antioquia, Colombia, where it is critically endangered because its populations are threatened by the damming of the river for a hydroelectric plant. The epiteth argos is the name of the conglomerate that intends to build the dam, and is given to the palm as a plea for the conservation of the Samaná Norte River canyon.

We describe here Bertolonia lucernula, a new endemic species from the state of Espírito Santo, Brazil. It is only known from one locality, the “Área de Proteção Ambiental Mestre Álvaro”, in the municipality of Serra. The new species can be recognized by the branches and petioles covered with sessile and short-stalked glands and scattered unbranched trichomes, flat leaf blade surfaces covered only with sessile and short-stalked glands, small flowers with a widely campanulate hypanthium covered with the same trichomes as the petioles, calyx with membranaceous, truncate sepals, and short, triangular external teeth, asymmetric and obovate petals, with the apex covered with sessile and short-stalked glands on the adaxial surface. According to IUCN criteria, Bertolonia lucernula should be classified as Critically Endangered (CR).

A New Species

A new endemic and critically endangered species of Rudgea (Rubiaceae) from Southeastern Brazil is described and illustrated. Rudgea minutifolia Bruniera & Torres-Leite is distinguished by its small leaves, a character found in only a handful of species in this genus. The indumentum of the branches, leaves and stipules, low number of secondary veins, corniculate corolla lobes, and vinaceous to almost black mature fruits are also characteristic of this species. Discovered in a forest remnant within the Atlantic Rainforest domain in the south of Espírito Santo state, this species is found only in the municipality of Castelo, an area that has been recognized as prioritary for conservation. Besides the description, taxonomic comments, conservation status, images and illustrations are provided.

The Alagoas Tyrannulet Phylloscartes ceciliae is a Critically Endangered species with a restricted distribution to the Atlantic Forest of the Pernambuco Endemism Center.  It seems to specialize in using the sally-strike maneuver (68.85%) to catch prey on green foliage (50.82%) and in the air (34.42%).  We calculated a catch rate of 2.93 catches/minute, identified a new food item for this species (caterpillars), and included 12 species in the list of birds recorded in mixed flocks with the species.  Our results show that majority of the prey capture events by Alagoas Tyrannulet occurred inside tree canopies, thus we can infer that this species needs a more advanced stage of forest sucession, with higher trees, emphasizing the urgency for restoration programs in the region.

Abstract Queimada Grande (QGI) is a small, legally protected island off the southeastern coast of Brazil that harbors two endemic and critically endangered herpetofauna species: the Golden Lancehead viper (Bothrops insularis) and a hylid frog (Scinax peixotoi); its vegetation, however, has been little studied. We integrated remote sensing and phytosociology of the Atlantic Forest on QGI to characterize the habitat of those two species and support their in situ conservation. QGI retains a mosaic of Atlantic Forest, rock outcrop and anthropogenic vegetation, including invasive alien species, and bare rock surfaces. Mature Atlantic Forest, the preferential habitat of B. insularis and S. peixotoi, currently covers ~28 ha (~50%) of QGI and shows very low tree richness and an oligarchic structure. The most important species are Guapira opposita, Rudgea minor and Aspidosperma australe. Anthropogenic formations cover ~9% of the island and do not seem to have expanded in recent years. Based on local conditions, we recommend permanent monitoring of QGI and the use of local tree species in projects to restore the habitat of those two endangered species.

Monographic work on the genus Hippeastrum in Brazil has revealed two new species endemic to the Cerrado biome, here described and illustrated. Hippeastrum lunaris is a species restricted to the region of Chapada dos Veadeiros; H. mauroi is so far found only in Chapada dos Guimarães. Detailed descriptions, illustrations and taxonomic comments on the conservation status of these species are provided, in addition to comparisons with morphologically similar species. An identification key to the species of Hippeastrum occurring in the Brazilian Cerrado is presented, accompanied by photographs of these species in their natural habitats.

Pseudochthonius ramalhosp. nov. is described to Gruna do Vandercir cave, in the Serra do Ramalho karst area, southwestern Bahia, Brazil. This area has an extensive limestone outcrop, with several caves, and the occurrence of potential minerals that are financially attractive for mining projects. The new species shows troglomorphic characteristics such as the depigmentation of the carapace and absence or reduction of eyes. It is a rare troglobitic species, and following the criteria of IUCN, we categorized the species as Critically Endangered – CR, IUCN criteria B1ab(iii)+2ab(iii). According to Brazilian legislation, locations, where critically endangered species live, can be protected by law, and we consider this cave/region to be of maximal relevance for protection.
