The southeastern Atlantic Forest of the Zona da Mata Mineira is located in the extreme north of Minas Gerais state, Brazil. The Serra da Mantiqueira, is a mountainous region with a high diversity of small non-volant mammal species, several of which are rare species or endemic lineages. The presence of cryptic species in small mammals makes the karyotype an excellent tool for identification and detection of new lineages. We analyzed the karyotype of 14 species: 11 rodents – Abrawayaomys ruschii, Akodon cursor, Blarinomys breviceps, Delomys sublineatus, Juliomys ossitenuis, Oligoryzomys nigripes, Oligoryzomys flavescens, Oxymycterus dasytrichus, Rhipidomys tribei, Sooretamys angouya, and Thaptomys nigrita; and three marsupials – Monodelphis scalops, Philander quica, and Marmosops incanus. We described for the first time the fundamental autosomal number and the morphology of sex chromosomes of Abrawayaomys ruschii, a rare sigmodontine species, and described a new karyotype for Blarinomys. The revision of published karyotypes of the species herein studied enabled the expansion of the geographic distribution of Oligoryzomys nigripes and Delomys sublineatus.

Herein we report for the first time the occurrence of Phaenomys ferrugineus in the state of Minas Gerais and present additional data on the geographical distribution of Abrawayaomys ruschii and Rhagomys rufescens in this state. These latter two species were reported from some localities in the Atlantic Forest of Brazil, but their presence in Minas Gerais state is restricted to few localities. These data reinforce the necessity of surveys over long periods of time and the use of pitfall traps in order to establish the real geographical distribution of small mammal species and to indicate priority areas for the conservation of this group of mammals.

Abstract The importance of continuously conducting botanical inventories has been questioned in recent decades, generating a lack of investment and interest in this area. However, several applied studies are only possible after obtaining the primary data from such surveys. Despite having the greatest richness of plants known in Brazil, several areas with knowledge gaps remain in Minas Gerais (MG) state. This is the case for the Serra da Mantiqueira, an important area for biodiversity conservation in the country. In this scenario, the phytophysiognomy of Seasonal Semi-deciduous Forest (SSF) deserves attention, as it is broadly distributed and has great relevance in the state, although subsampled. Therefore, this study aimed to present records of species for the flora of MG and discuss the need for floristic surveys in Brazil. These species were recorded in three of 10 studied remnants along expeditions performed between the years of 2012 and 2019 as part of a wide study performed in SSF remnants in the Serra da Mantiqueira which have a deficit of floristic data. Three species are recorded for the first time in MG, one species was rediscovered after more than two centuries from the last collection (which represents its nomenclatural type), in addition to nine other species which must be considered rare in the state. This study contributed to filling gaps in knowledge on Brazilian flora and also demonstrated the relevance of continuing new collections, mainly in specific subsampled areas in the interior of the country such as in SSF remnants.

The objectives of this study were to identify anthophilous butterflies on psychophilous flowers of four Asteraceae species in an Atlantic Forest fragment in Viçosa, Minas Gerais State, Southeastern Brazil, and to determine whether there are species in common with other lepidopteran inventories of the Southeastern and Midwestern regions of Brazil. It is the first inventory of anthophilous butterflies of a semideciduous forest fragment in Zona da Mata, State of Minas Gerais. A total of 108 species were recorded, representing the fourth largest lepidopteran survey in this State. The results demonstrated that Asteraceae species may be important tools for monitoring anthophilous butterflies. The similarity with other inventories ranged from 1 to 92.55%. Fifteen species were reported for the first time in the State of Minas Gerais, and among them, Melanis alena and Thisbe irenea were observed in this study only.

The Drosera villosa complex is here reviewed and includes six species endemic to Brazil: D. villosa, here identified for the first time as a narrow endemic species native to the neighboring highlands of the Serra Negra and Serra do Ibitipoca, in southern Minas Gerais state; D. ascendens, rediscovered nearly 200 years after its description, narrowly endemic to the Diamantina Plateau, central Minas Gerais; D. graomogolensis, endemic to northern Minas Gerais, but here found to be more widespread than previously reported; D. latifolia, a highly polymorphic and widespread taxon, previously placed in synonymy of D. villosa and heretofore misidentified as D. ascendens, is here elevated to species rank; and two new species here described, D. riparia and D. chimaera. Furthermore, two new natural hybrids are reported: D. villosa × D. tomentosa var. glabrata and D. latifolia × D. tomentosa. The morphological characters distinguishing these taxa from each other and from similar species are discussed, together with habitat and ecological information, detailed illustrations and photographs, distribution maps, and a key to the species of the D. villosa complex is provided.

ABSTRACT The objective was to present the floristic survey of the bryophytes of the Parque Estadual da Serra do Brigadeiro. It included an evaluation of the species richness, as well as information about the substrate preference of each species and its geographic distributions in Brazil. We found 208 taxa of bryophytes: one hornwort, 88 liverworts and 119 mosses. This richness represents ca. 26% of the bryoflora of Minas Gerais State and ca. 13% of that known for Brazil. Eighteen of the bryophytes species are endemic to Brazil, whereas 19 species are recorded for the first time in Minas Gerais. The bryoflora showed preference for tree bark (30%) and rock (23%) as substrates. Our data show that the Parque Estadual da Serra do Brigadeiro is an important area for the diversity conservation of Brazilian bryophytes and maintenance of endemic species of the country.

This paper reports for the first time in the Cerrado region of Brazil the occurrence of white mold caused by Sclerotinia sclerotiorum in coriander (Coriandum sativum), parsley (Petroselinum crispum) and Peruvian carrot (Arracacia xanthorrhiza). The disease was observed on coriander, in Cristalina, Goiás State, on parsley in Gama, the Federal District and on Peruvian carrot in Ibiá, Minas Gerais State. Pathogenicity tests demonstrated that the fungus S. sclerotiorum is the causal agent of the observed symptoms in these plants. The three isolates obtained from naturally infected plants were inoculated in coriander (cv. Verdão), parsley (cv. Lisa Gigante), Peruvian carrot (cv. Amarela de Senador Amaral) and carrot (cv. Forto Nantes) and they were pathogenic to these hosts. The fungus isolates were re-isolated from inoculated plants fulfilling Koch´s postulates and also confirming that S. sclerotiorum is a polyphagous pathogen.

The freshwater crab Trichodactylus fluviatilis Latreille, 1828 is recorded here for the first time, at an altitude above 1000 m a.s.l. Sampling was performed in the Grota stream in Campos das Vertentes, Minas Gerais state, Brazil. This new record extends the known altitudinal distribution to 1115 m a.s.l., which significantly contributes to understanding the conditioning limits and factors for this species’ distribution. Moreover, the occurrence of an ectosymbiont platyhelminth of the genus Temnocephala is also reported on the crabs collected.

Abstract: Odonata is considered, among the aquatic insect orders, the second largest group in number of species. Its global richness is estimated in about 6,000 described species. The Brazilian richness represents around 14% of the world's odonatofauna, however, the knowledge on Brazilian dragonflies distribution is still poor. This study purpose an inventory of the dragonflies species present in aquatic habitats from a Preserved Area according to the Brazilian Forest Code, located in the Cerrado biome at Triângulo Mineiro, Minas Gerais. In the dry season, from April to June of 2017, we collected 680 specimens belonging to 36 species and six families. Among the collected species, Elasmothemis williamsoni was observed by the first time in Minas Gerais State, and we also found a new species of Tigriagrion (Zygoptera: Coenagrionidae) which is being described by taxonomists. Considering the fast agricultural advance over natural Cerrado systems, species lists can be important to define priority conservation areas for odonate species.
