Leaf Cutting

Khaya grandifoliola C. DC. (Meliaceae), known as African mahogany, is used in the establishment of commercial plantations for high-value timber production. This work aims to report the first occurrence of the genus Atta in a commercial plantation of this species. An ant nest mound with 105 m2 of loose soil and five active ant holes were observed. Leaves cut into crescent shaped sections and pieces of young branches were found near these holes, in addition to trees with the apical part of their crown partially defoliated. The collected specimens were identified as Atta laevigata Smith (Hymenoptera: Formicidae: Attini), locally known as the glass-head leaf-cutting ant.

Pleurolophocercous cercariae emerged from naturally infected Melanoides tuberculata from Minas Gerais State, Brazil, were used to perform experimental infection of laboratory-reared Poecilia reticulata. Mature metacercariae were obtained from the gills of fishes and force-fed to Mus musculus. The adult parasites which recovered from small intestines of mice were identified as Centrocestus formosanus. This is the first report of M. tuberculata as intermediate host of this heterophyid in Brazil.

A New Species

Microvelia joceliae Magalhães & Moreira, sp. nov. is described and illustrated based on material from Parque Natural Municipal das Andorinhas, Minas Gerais State, in southeastern Brazil. The new species can be distinguished from congeners occurring in the region by the pronotum of the apterous form covering almost the entire thorax dorsally, proepisternum with black denticles, male abdominal segments V–VII ventrally depressed, shape of the asymmetrical parameres, and female abdominal laterotergites reflected over the mediotergites and almost touching over segments V–VII.

Begonia piranga (Begoniaceae) is a new narrowly endemic species from the campos rupestres of Serra do Padre Ângelo, a quartzitic massif in Conselheiro Pena, eastern Minas Gerais state, Brazil. Description, diagnosis, taxonomic comments, detailed illustrations, field photographs, and a provisional IUCN Red List Assessment are provided. The new species is considered Critically Endangered due to its restricted occurrence in high elevation rock outcrops, small population size, and decline in the quality of the habitat. Begonia vasconcelosiana, another Critically Endangered species, is also newly reported here for Serra do Padre Ângelo. These discoveries add to the increasing list of novelties from Serra do Padre Ângelo, reinforcing the urge for conservation actions to protect the endemic flora of this Serra and other areas of campos rupestres in eastern Minas Gerais state.
