AbstractThe bush dog Speothos venaticus, a rare Near Threatened South American canid that lives in packs, was thought to be extinct in Minas Gerais state, south-eastern Brazil, until recently. Here, we report four recent records of the species in Minas Gerais, the first in the state since the description of the species in 1842. All records are from the Cerrado ecosystem in the north and north-west of the state; two are from animals found dead, one from footprints and another from a camera trap. Three of the records were inside or close (< 10 km) to strict protected areas, in a region recognized as the Protected Areas Mosaic Sertão Veredas–Peruaçu, where we expect any new records of the bush dog to be found. We discuss the low probability of detecting the bush dog and the main regional threats to the species, and emphasize the need to protect large and interconnected natural areas and keep them free of domestic dogs to avoid the extinction of the bush dog in Minas Gerais.

Pseudolaelia Campos Porto & Brade (1935: 209) is a small orchid genus in subtribe Laeliinae. Its phylogenetic affinities place it near several small, endemic genera which constitute an isolated lineage in eastern Brazil, together with Adamantinia Van den Berg & Gonçalves (2004: 231), Constantia Barbosa Rodrigues (1877: 78), Isabelia Barbosa Rodrigues (1877: 75) and Leptotes Lindley (1833: t. 1625). All these genera have comparatively fewer species within the subtribe, and the main centre of distribution are the Brazilian Campos Rupestres, and other granitic rocky outcrops in the Brazilian States of Minas Gerais, Espírito Santo, Rio de Janeiro and Bahia. Also, several species in Pseudolaelia, Constantia and Leptotes are epiphytes on Vellozia sp., considered a very specialized type of epiphytism (van den Berg et al. 2006, Porembsky 2008).

The genus Hylodes Fitzinger, 1826 is restricted to eastern Brazil, occurring from the states of Espírito Santo to Rio Grande do Sul (Lingnau et al. 2008, Frost 2010). Except for Hylodes otavioi, which inhabits riparian forests in rocky fields (“campos rupestres”) habitats within the Cerrado domain in Minas Gerais State (Sazima & Bokermann 1982), all other species in the genus are endemic to the Atlantic Rainforest domain (Lingnau et al. 2008). The genus currently comprises 24 species (Frost 2010) of small to medium-sized diurnal frogs that live associated to lotic streams in forests (e.g. Lingnau et al. 2008; Silva & Benmaman 2008). Heyer (1982) proposed four species groups for Hylodes, which are still recognized today (but see Haddad et al. 1996; Canedo & Pombal 2007): the glaber (formerly pulcher), lateristrigatus, mertensi, and nasus species groups. The Hylodes lateristrigatus species group is the most specious, being currently composed by 18 species: H. amnicola Pombal, Feio, and Haddad, 2002, H. babax Heyer, 1982, H. charadranaetes Heyer and Cocroft, 1986, H. fredi Canedo and Pombal, 2007, H. heyeri Haddad, Pombal, and Bastos, 1996, H. lateristrigatus (Baumann, 1912), H. magalhaesi (Bokermann, 1964), H. meridionalis (Mertens, 1927), H. ornatus (Bokermann, 1967), H. otavioi Sazima and Bokermann, 1983, H. perere Silva & Benmaman, 2008, H. perplicatus (Miranda-Ribeiro, 1926), H. pipilans Canedo and Pombal, 2007, H. phyllodes Heyer and Cocroft, 1986, H. regius Gouvêa, 1979, H. sazimai Haddad and Pombal, 1995, H. uai Nascimento, Pombal, and Haddad, 2001, and H. vanzolinii Heyer, 1982 (Silva & Benmaman 2008; Frost 2010).

Encholirium is an exclusively Brazilian genus of Bromeliaceae that occurs principally in the South American dry diagonal, with only a few species found on inselbergs within the Atlantic Forest. The center of diversity of the genus falls within the Campos Rupestres of the Espinhaço Range of the state of Minas Gerais, followed by rocky outcrops found within the Caatinga and Cerrado biomes. Three new species are described and illustrated, two of which occur on limestone outcrops in western Bahia (Encholirum splendidum and Encholirium fragae), while the third, Encholirium kranzianum, occurs in the Campos Rupestres of the Espinhaço Range of Minas Gerais.

Embora o potencial mineral do Brasil seja imenso e, por conseguinte, a possibilidade de encontro de novas espécies minerais nos empreendimentos minerários seja naturalmente alta, até 2010 somente 51 descobertas haviam sido verificadas no país. Entretanto, nos últimos sete anos, através de um projeto de Tese de Doutoramento realizado no Programa de Pós-Graduação em Geologia do IGC/UFMG, esta situação procurou ser mudada. Com ênfase em dois dos principais ambientes geológicos do Estado de Minas Gerais e adjacências, a Província Pegmatítica Oriental do Brasil e a Serra do Espinhaço, estudos foram conduzidos visando especificamente o encontro de novos minerais. Destacam-se os resultados extremamenete satisfatórios; nesses anos foram descobertos oito minerais, o que representa média de 1,3 mineral/ano, contrastando com os inexpressivos 0,2 mineral/ano verificados desde 1789 (ano em que o crisoberilo foi descrito). Os novos minerais são, incluindo seus códigos de identificação na International Mineralogical Association (IMA): carlosbarbosaíta [(UO2)2Nb2O6(OH)2.2H2O], IMA 2010-047; pauloabibita [NaNbO3], IMA 2012-090; cesarferreiraíta [Fe2+Fe3+2(AsO4)2(OH)2.8H2O], IMA 2012-099; correianevesita [Fe2+Mn2+2(PO4)2.3H2O], IMA 2013-007; almeidaíta [Pb(Mn,Y)Zn2(Ti,Fe3+)18O36(O,OH)2], IMA 2013-020; wilancookita [(Ba,K,Na)8(Ba,Li,[])6Be24P24O96.3H2O], IMA 2015-034; parisita-(La) [CaLa2(CO3)3F2], IMA 2016-031; e brandãoita [BeAl2(PO4)2(OH)2(H2O)4], IMA 2016-071a. Este foi o primeiro programa de pesquisa desenvolvido no país voltado especialmente para a descoberta de novos minerais, tendo alcançado pleno êxito.Palavras Chave: Novos minerais, Centro de Pesquisa Prof. Manoel Teixeira da Costa, (IGC-UFMG), BrasilAbstract:RECENT MINERALS DESCRIBED IN BRAZIL: PARTICIPATION OF THE CENTRO DE PESQUISA PROF. MANOEL TEIXEIRA DA COSTA - CPMTC, GEOSCIENCES INSTITUTE (UFMG). Although the mineral potential of Brazil is immense and, consequently, the possibility of finding new mineral species in mining projects is obviously high, until 2010 only 51 discoveries had been verified in this country. However, in the last seven years, through a PhD Thesis project carried at the Postgraduate in Geology Program of the IGC/UFMG, this situation has been modified. With emphasis on two of the main geological environments of Minas Gerais State and surrounding regions, the Eastern Brazil Pegmatite Province and the Espinhaço Mountain Range, studies were conducted specifically aimed at finding new minerals. The results are extremely satisfactory; in those years eight minerals were discovered, representing an average of 1.3 mineral/year, contrasting with the inexpressive 0.2 mineral/year verified since 1789 (year of chrysoberyl description). The new minerals are, including their identification codes in the International Mineralogical Association (IMA): carlosbarbosaite [(UO2)2Nb2O6(OH)2.2H2O], IMA 2010-047; pauloabibite [NaNbO3], IMA 2012-090; cesarferreiraita [Fe2+Fe3+2(AsO4)2(OH)2.8H2O], IMA 2012-099; correianevesite [Fe2+Mn2+2(PO4)2.3H2O], IMA 2013-007; almeidaite [Pb(Mn,Y)Zn2(Ti,Fe3+)18O36(O,OH)2], IMA 2013-020; wilancookite [(Ba,K,Na)8(Ba,Li,[])6Be24P24O96.3H2O], IMA 2015-034; parisite-(La) [CaLa2(CO3)3F2], IMA 2016-031; and brandãoite [BeAl2(PO4)2(OH)2(H2O)4], IMA 2016-071a. This was the first research program developed in the country focused especially on the discovery of new minerals, reaching full success.Keywords: New minerals, Prof. Manoel Teixeira da Costa Research Center (IGC-UFMG), Brazil.

The study of fluvial dynamics of the Rio das Velhas in the section connecting the Quadrilátero Ferríferoand the Bambuí basin, relying on a compilation of geomorphological, sedimentological and structuraldata indicates a Cenozoic morphogenesis controlled by uplift of regional scale with interference of faultslocated at the contacts of morphostructural compartments. These compartments are strongly adapted tothe Precambrian litostructural domains controlling the geomorphological configuration of the differentparts of the river valley.The initial chronological datum is marked by remainders of the Sulamericana Surface (Neogene).During the Plio-Pleistocene period three levels of stepped terraces were formed. During the Holocene ainner floodplain developed in the Lower Terrace.The level of the Upper Terrace (Pliocene) corresponds to the end of dissection phase which reaches adepth of 150 m and shows a equilibrated longitudinal profile over the whole area. The sediments of theMiddle and Lower Terraces have been deposited after new dissection phases with minimum depths of 60and 10 m, respectively. These data of dissections depths and the stamped position of the floodplain confirmsthe gradual decreasing of the regional uplift intensity during the Pleistocene times.The last three events of the valley formation indicate a superimposition of the Rio das Velhas onto thestructures of the Quadrilátero Ferrífero with formation of a water-gap at the passage of the Serra do curral,named “Fecho de Sabará”. In consequence occurs a strong local retention of alluvial sediments causing aimportant alteration of river dynamics.The decreasing uplift during Holocene times is accompanied by the transition from braided channelssystems, prevailing during the Pleistocene, to a meandering channel type. The effects of historic miningactivity induce the return to the braided system.Tectonic activity by faulting is demonstrated by dislocations in the alluvial sequences of the LowerTerrace and in the longitudinal profile of the Middle and Upper Terraces with a total off-set of 50 m aswell as by river capture younger than the Middle Terrace.

The community of orchid bees (Hymenoptera: Apidae: Euglossina) was studied at an area in the transition between the Cerrado and Atlantic Forest biomes, from March, 2010 to February, 2011 in the Barroso region, state of Minas Gerais, eastern Brazil. Orchid-bee males were collected with bait traps containing three different scents (cineole, eugenol and vanillin) and with entomological nets for collecting bees on flowers. A total of 614 orchid-bee males were collected using aromatic traps, belonging to four genera and 15 species. Twenty-five female specimens belonging to two genera and at least three species were collected on flowers. Eulaema (Apeulaema) nigrita Lepeletier, 1841 was the most abundant species (50% of collected specimens), followed by Euglossa (Euglossa) truncata Rebêlo & Moure, 1996 (28%). Cineole was the most attractive compound (66.5% of males and 13 species), followed by eugenol (16% and 9 species) and vanillin (13.5% and 4 species). Eulaema (Apeulaema) marcii Nemésio, 2009 and Eufriesea auriceps (Friese, 1899) were attracted to all scents, whereas Euglossa species were collected only in cineole and eugenol.

Portulaca hirsutissima (Portulacaceae) is a succulent herb occurring in open fields, sandy or rocky soil of separate Brazilian areas. On the basis of the analyses of seeds and pollen grains macro- and micromorphology, a significative variation, which is related to the distribution pattern, was found. Two new species are here proposed, described and illustrated. Portulaca giuliettiae sp. nov. occurs in Eastern Brazil, from Paraiba to Rio de Janeiro and P. goiasensis sp. nov. is restricted to the Chapada dos Veadeiros, in Central Brazil. P. hirsutissima is now to be considered as a restricted species from Minas Gerais State. A lectotype for the name P. hirsutissima is designated from a specimen preserved at P.
