Urogenital Papilla

The diversity and geographic distribution of Phalloceros Eigenmann, 1907 in the Ilha Grande Bay Hydrographic Region, in southeastern Brazil, is investigated. Examination of 81 samples revealed the presence of 5 species in the region: Phalloceros anisophallos Lucinda, 2008, P. aspilos Lucinda, 2008, P. enneaktinos Lucinda, 2008, P. harpagos Lucinda, 2008, and P. tupinamba Lucinda, 2008. Phalloceros harpagos and P. tupinamba are recorded for the first time in the area. The geographic ranges of P. anisophallos and P. enneaktinos are expanded. The 5 species belong to 3 distinct morphologies of the female urogenital papilla. Species from these distinct morphological lineages may occur sympatrically, but species within the same lineage are always allopatric. A key for the identification of these species is provided.

The present paper aims to investigate the relative sea-level and the coastal evolution during the Holocene in the Rio de Janeiro coastline, based on geological and biological indicators. Using topographic survey, excavation and coring, and 14C dating of these coastal deposits and beachrocks outcrops, we have reconstructed a sea-level curve for the Holocene. For the first time on the Brazilian coast it was identified a negative record of relative sea-level during Late Pleistocene and Early Holocene transition. After the transition, a relatively rapid increase of sea-level began. At approximately at 8500 cal yr BP, the sea-level was 0.5 m below the current level, was overtaken for the first time in the Holocene, at approximately 7500 cal yr BP. The maximum level of +2.5 m was reached between 4770 and 4490 cal yr BP. At the point of maximum transgression, the sea-level began a general behavior of lowering until the present. These results confirm other data already obtained elsewhere along the Atlantic coast of South America. The results of this study are consistent with previous researches and they help to refine the Holocene sea-level record along the Brazilian coast.

Abstract: We provide an inventory checklist of the amphibians from Parque Nacional da Restinga de Jurubatiba (PNRJ), a sandy coastal environment in southeastern Brazil. As a result of three years of surveys, from August 2013 to June 2016, a total of 36 amphibians species were recorded - one Gymnophiona (Typhlonectidae) and 35 species of five anuran families: Bufonidae (2 species), Craugastoridae (1), Hylidae (21), Leptodactylidae (8), and Microhylidae (3). One specie is reported for the first time for the restinga ecosystem (Chthonerpeton braestrupi) and 24 species were recorded for the first time to the PNRJ. This result reinforces the importance of long-term studies for accurate knowledge of the biodiversity. Considering that the biodiversity of the fragments of the sandy coastal environments in the state of Rio de Janeiro is poorly known, the present study provided a more detailed knowledge about different aspects of the biodiversity in the PNRJ, contributing to the preservation of this threatened ecosystem.

We present new records of Passifloraceae sensu stricto from Itatiaia National Park, Brazil, contributing new data on the geographic distribution of four Passiflora L. species to the flora of Brazil: P. deidamioides Harms, P. miersii Mast., P. rhamnifolia Mast., and P. setulosa Killip. The last three species are reported from Itatiaia National Park and the last species from the state of Rio de Janeiro for the first time.

We report a female Physalaemus soaresi Izecksohn, 1965 collected at the Atlantic rainforest of Serra do Mendanha, municipality of Rio de Janeiro, state of Rio de Janeiro, southeastern Brazil. Known only from two localities (and probably extinct in one), P. soaresi is considered a threatened species in Brazil and presumably threatened in the state of Rio de Janeiro. Despite the new record, P. soaresi still fits into the status of endangered and requires the full protection of all areas where it occurs.

Solanum mellobarretoi, a new species of Solanum subg. Leptostemonum (Solanaceae), is described and illustrated. It is endemic to Brazil and restricted to the southern Espinhaço Range in the State of Minas Gerais, southeastern Brazil. Solanum mellobarretoi is morphologically related to S. leptostachys Dunal, from which it differs by its irregularly lobed lanceolate to ovate-lanceolate leaves, irregularly lobed, ovate to lanceolate calyx lobes, larger flowers, and pentagonal rotate corolla with cuspidate lobes. Although known in other groups of Solanum, the explosive seed dispersal mechanism found in this species is described here for the first time for the spiny solanums. The affinities with S. leptostachys, geographic distribution, ecology and conservation status of S. mellobarretoi are discussed.
