The diversity of Eriocaulaceae in the Neotropics is primarily concentrated in the Espinhaço Range in Brazil and in the Tepuis of Venezuela. Species richness outside of these areas, however, is significant but poorly known. Based on improved taxonomic knowledge about Eriocaulaceae in the Atlantic Forest domain in Brazil, we propose nomenclatural and taxonomic changes, and provide an identification key and an annotated list of the species of the core Serra da Mantiqueira. A total of 24 species were found, one described quite recently and two still known only from the type specimens. Lectotypes for the following names are designated: Eriocaulon majusculum, Paepalanthus exiguus, P. jordanensis, P. manicatus, and Syngonanthus caulescens.

Taxonomic Changes

A revision of the genus Macromalthinus resulted on recognition of twelve species, six of which are herein proposed as new: Macromalthinus belemensis Brancucci, 1981, M. brasiliensis (Pic, 1906), M. globuliventris Brancucci, 1981, M. guyanensis sp. nov., M. luteoapicalis sp. nov., M. maximiceps Pic, 1919, M. orapuensis sp. nov., M. piceiventris sp. nov., M. quadratithorax sp. nov., M. santaremensis Brancucci, 1981, M. schmidli Constantin, 2010 and M. xerophilus sp. nov. No taxonomic changes were necessary in the previously described species, which are distinguished through differential diagnosis and an updated identification key. The type specimens of all species were revisited and their photographs are provided. Discussions on the diagnostic character of each species, general morphology and the first description of wings and female genitalia of Macromalthinus are presented, as well as the first description of the female of M. maximiceps Pic, 1919. Finally, new records and distribution maps are presented for all species.

First Time

Based on a study of samples made by the author, 70 species of freshwater bivalves belonging to 6 genera and 2 families are recorded for the Taz River basin (north of Western Siberia). An annotated list of bivalves of the Taz basin is provided, with data on species’ range, their findings in Western Siberia and within the studied area. Some information about bionomics and abundance of bivalves are given. 45 species are for the first time registered in this basin. Most studied molluscan communities are characterized by low species richness; the distribution of species by their occurrence was extremely uneven. 22 species are characterized as rare. The highest species richness of bivalves was found in river channels, rivers and brooks; the lowest - in temporary habitats. The core of the fauna is constituted by species with broadest range (cosmopolitan, trans Holarctic, trans Palearctic) as well as by taxa with European Siberian type of distribution. From the taxonomic point of view, the bivalve fauna of the Taz basin is relatively separated from the faunas of other river basins of Western Siberia and is more similar to the fauna of the Lower Yenisean zoogeographic province (sensu Starobogatov [1986]).

Three new species of Otostigmus Porat, 1876 from Brazilian Atlantic Forest are described. Otostigmus beckeri sp. n. andO. lanceolatus sp. n. are described from the state of Bahia and O. giupponii sp. n. from the state of Espírito Santo. InBrazil, the otostigmine scolopendrid genus Otostigmus comprises 22 species. A summary of Brazilian Otostigmus speciesis presented with new distribution records, taxonomic remarks when appropriate and an identification key. Otostigmus sul-catus Meinert, 1886 is recorded for the first time from Brazil; the Andean Otostigmus silvestrii Kraepelin 1903, previouslyrecorded from Brazil, is here considered not to be present in this country. Eight nominal species are regarded here as newsynonyms. Five of them—Otostigmus pradoi Bücherl, 1939, O. longistigma Bücherl, 1939, O. longipes Bücherl, 1939,O. langei Bücherl, 1946 and O. dentifusus Bücherl, 1946—are based on females of O. tibialis Brölemann, 1902. O. latipesBücherl, 1954 is conspecific with and is considered a junior synonym of O. sulcatus Meinert, 1886; O. limbatus diminutusBücherl, 1946 is a junior synonym of O. limbatus Meinert, 1886 and O. fossulatus Attems, 1928 is a junior synonym of O. goeldii Brölemann, 1898.

Disturbed Habitats

Habitat fragmentation causes a sharp increase in the forested area affected by edge effects (Murcia 1995). Compared with the core of the forest, edges present higher litterfall rates, air and soil humidity reduction, higher temperature and increased wind incidence (Bierregaard et al. 1992, Didham & Lawton 1999, Laurance et al. 1998, Matlack 1993). These features of edges may increase the probability of fire occurrence, especially if the surrounding vegetation is composed of grasses (D'Antonio & Vitousek 1992, Freifelder et al. 1998). After a fire, the damaged edge will grow substantial amounts of herbaceous vegetation, extending the inflammable area into the forest, and thereby creating a positive feedback system of fire susceptibility and intensity (Cochrane & Schulze 1999, Cochrane et al. 1999). Fires may affect the structure and composition of the vegetation (Cochrane & Schulze 1999, Didham & Lawton 1999, Sanaiotti & Magnusson 1995), favouring, in the long-term, the dominance of the community by species characteristic of disturbed habitats and making the habitat unsuitable to primary forest species (Malcolm 1994, Possingham et al. 1994). Unfortunately, there are few studies on the effects of fires on neotropical small-mammal populations (Borchert & Hansen 1983, Ojeda 1989, Vieira & Marinho-Filho 1998). The objective of this study was to analyse the influence of a fire on populations of two rodent species, Akodon cursor (Winge) and Oecomys concolor (Wagner) in two fragments of Atlantic Forest in Brazil.

The following are new combinations: Aleiodes insignis (Brues 1926), Aleiodes lateralis (Cameron 1905), Aleiodes maculicornis (Brues 1926), Aleiodes siccitesta (Morley 1937), Cyclophatnus flavum (Cameron 1910), Rhaconotus striatulus (Cameron 1909), Tolonus cingulatorius (Morley 1912), Zatypota tropica (Morley 1912). Netelia morleyi Townes, Townes & Gupta 1961 is transferred from the subgenus Netelia Gray 1860 to the subgenus Paropheltes Cameron 1907. One new replacement name is proposed: Aleiodes philippinensis nom. nov. for Rhogas lateralis Baker 1917, nec Troporhogas lateralis Cameron 1905. Lectotypes are designated for Antrusa persimilis Nixon 1954, Rhyssalus striatulus Cameron 1909, Troporhogas trimaculata Cameron 1905, Hemiteles cingulatorius Morley 1912, Paniscus ferrugineus Cameron 1889 and for Xanthojoppa inermis Morley 1917. Some previously overlooked type specimens are interpreted and illustrated and some errors in the literature corrected. Hosts are recorded for two genera of Ichneumoninae for the first time: Catadelphops nasutus (Heinrich 1962) was reared from Proserpinus terlooii (Edwards 1875) (Lepidoptera: Sphingidae) in the USA, and Aethianoplis excavata (Roman 1910) was reared from Precis octavia (Cramer 1777) (Lepidoptera: Nymphalidae) in Uganda.

The aim of this study is to survey the angiosperms of two montane forest remnants in the southern Bahia, Brazil: Corcovado (SCO) and Pedra Lascada (SPL). Both fragments are located in the municipality of Almadina and Barro Preto, respectively, and are 18 km distant from each other. We sampled 899 species of angiosperms distributed in 437 genera and 116 families. The SCO was the richest area with 678 species, distributed in 367 genera and 100 families. SPL showed 466 species in 269 genera and 88 families. The percentage of species identified was 85.8% and of this total, 37.7% are endemic to the Atlantic Forest, 11.2% are endemic to southern Bahia and northern Espírito Santo and 7% are disjunct between the Atlantic Forest and Amazon. The remaining percentages (44.3%) were of species widely distributed. The richest families in the two areas were Orchidaceae (10%), Rubiaceae (7%), Bromeliaceae (5.5%), Melastomataceae (4.2%) and Poaceae (4%). The richest genera were Psychotria (2%),Piper (1.8%), Ocotea (1.6%),Vriesea (1.5%) and Peperomia (1.4%). More than half of the recorded species showed non-arboreal habit, regarding life forms documented. That comes against the assertion that many authors in the tropical forests, where species richness in angiosperms is expected for non-woody species, especially in montane forests. Twelve species have been identified as new, but seven others already described from collections previously obtained in these two areas. Orchidaceae, Rubiaceae, Poaceae and Bromeliaceae showed significant richness in this study these families are commonly reported as the richest in other inventories in the Atlantic Forest in southern Bahia reinforcing their importance to the regional flora. The high levels of richness, endemism, and the growing numbers of new taxonomic discoveries from the SPL and SCO sites indicate the biological importance of these two forest remnants. The implementation of parks or other protected environmental reserves would be essential to the conservation of its species.
