Commensalism between Corydalus Latreille, 1802 (Megaloptera, Corydalidae) and Corynoneura Winnertz, 1846 (Diptera, Chironomidae, Orthocladiinae) larvae was recorded in Indaiá stream, at 1,380 m a.s.l. (Parque Nacional da Serra do Cipó, 19º-20ºS, 43º-44ºW) and in the headwaters of São Francisco river, at 1,300-1,700 m a.s.l. (Parque Nacional da Serra da Canastra, 20º00'-20º30'S, 46º15'-47º00'W), in Minas Gerais state, Brazil. Seventy eight Corydalus larvae (range 22-88 mm) were sampled: 61 in the Indaiá stream and 17 in other two streams. Twelve Corydalus larvae (22-79 mm) in the Indaiá stream and three out of 15 larvae in the headwaters of São Francisco river (38-50 mm) had Corynoneura, larvae and pupae on their gills (3rd to 6th) and a few larvae attached to the abdominal segments of larger Corydalus larvae (> 25 mm). Sixty-nine larvae of Corynoneura were found in the regurgitated material from Corydalus. It is remarkable that by attaching to larger body size predators, prey could become free from predator bouts and could also be transported by them.

The mammals of the Cerrado (Brazilian Savanna Biome) are still poorly known; only a few localities have been properly surveyed and studied. Hereby, we present a survey of the mammals of Serra do Cipó National Park, a protected area of Cerrado in Minas Gerais State, southeastern Brazil. A total of 55 species from eight orders were listed, which have been captured, observed or recorded in the literature. Some mammals are endemic or listed as threatened either by IUCN’s red list or by the national and regional red lists. Serra do Cipó National Park is an important site for scientific research and conservation of Minas Gerais’ biodiversity, though there is little information on mammal diversity and distribution in the park. We hope our study can help us fill this gap and improve the effectiveness of this national park in protecting Cerrado mammals and other vertebrates.

AbstractGamidactylus piranhus sp. nov. (Copepoda, Vaigamidae) from the nasal fossae of “San Francisco piranha”, Pygocentrus piraya (Cuvier, 1819) and.White piranha. Serrasalmus brandtii (Lütken, 1875) is described. The new species is similar to the type species of the genus, Gamidactylus jaraquensis Thatcher et Boeger, 1984, but differs from it in the following respects: the cephalothorax is shorter, the free thoracic segments are usually longer, leg 5 is reduced to a simple seta and a spine on the second antennal segment is lacking. Gamidactylus bryconis Varella, 1995 and Gamidactylus hoplius Varella et Malta, 1996, do not closely resemble the new species because they are much larger and both present leg 5 reduced to a double seta.

Macroinvertebrates as food were recorded for three anurans tadpoles: Hyla saxicola (Bokermann, 1964) (Hylidae), Scinax machadoi (Bokermann & Sazima, 1973) (Hylidae), and Bufo rubescens (Lutz, 1925) (Bufonidae). These species are commonly found in the mountain streams at Serra do Cipó National Park, Minas Gerais State, Brazil. Tadpoles were collected in pools of second-order reach in Mascates stream and third and fourth order reaches of Indaiá stream from March-October, 2003. Biometrical data were recorded before dissecting each individual and a feeding importance index was estimated. Eight taxa of chironomids and three taxa of mayfly exuviae were found in the guts, but no significantly differences were found between tadpole species (ANOVA, p > 0.05). The results support the drift transport hypothesis that predicts that tadpoles commonly ingest suspended matter in lotic ecosystems, are generalist feeders, and macroinvertebrates are probably incidental ingested.

Megalancistrus barrae is a species endemic to the São Francisco River basin that has not previously been recorded from the Upper São Francisco basin.The present work increases the known distribution of the species by reporting new collections from two different regions in the Upper São Francisco basin: one in the Pará River and the other in the São Francisco River, downstream Três Marias dam, Minas Gerais state. In addition, this study compiles distributional data on Megalancistrus barrae from museums.

AbstractBrasergasilus bifurcatus sp. nov. (Copepoda, Ergasilidae, Abergasilinae) is described. Specimens of the new species were collected from the gills and nasal fossae of the serrasalmid fishes, known as “piranhas”, Pygocentrus piraya (Cuvier, 1819) and “pirambebas”, Serrasalmus brandtii (Lütken, 1875). The fishes were netted in the Três Marias Reservoir (18°12′59″S, 45°17′34″W) of the upper São Francisco River, Minas Gerais State, Brazil. The new species differs from its congeners by the following characters: the specific setation on the antennule; the terminal barb of the antenna; the deeply bifurcate distal segment of the mandible; the chalice-shaped genital complex; a conspicuous external indentation of the second segment of the first endopod and a very short terminal segment of the first exopod.

A New Species

The Area of Environmental Protection of the Pandeiros River is the largest unit for sustainable use in Minas Gerais state, Brazil. The Pandeiros Wetland in the lower part of this river is considered a nursery for most migratory fish species of the São Francisco River and it is currently threatened by the introduced peacock-bass Cichla piquiti (Kullander & Ferreira, 2006). In this study, a list of fish species from the Pandeiros River was developed and compared with data for populations from other regions in the São Francisco basin. The presence of a new species record for the São Francisco River basin in the Pandeiros, and the particular local biotic and abiotic conditions of that river, support its recognition as an important conservation unit within the basin.

Narrow Endemics

Many species and infraspecific taxa in Mimosa are narrow endemics. Following the same pattern, two new Brazilian species of the genus, M. perplicata and M. serpensetosa are described, both from the Southern Espinhaço Range (one from Serra do Cabral, the other from Serra de Capanema and Serra do Cipó), in Minas Gerais state, a region known as a key area for Mimosa diversity. The description of more species sharing affinities with M. setosa var. paludosa indicates that the latter may be acting as a species pump.

Cerrado dry forest enclaves have been treated as an endemic bird area. In the last years, some avifaunal surveys have been conducted in dry forests on the left bank of the São Francisco River, eastern Brazil. Nevertheless, there is a gap of detailed ornithological surveys in the Cerrado dry forest enclaves on the right bank of this river. Here, we present the first avifaunal survey of a Cerrado dry forest enclave on the right bank of the São Francisco River. The study area, named “Curral de Pedras”, comprises a dry forest enclave and other associated habitats in central Minas Gerais state, southeastern Brazil. We recorded 172 bird species; nine taxa have their ranges strongly associated to the Caatinga; six present their ranges associated to the Atlantic Forest and one is typical of the Cerrado. Important records are those of Campylopterus calcirupicola, a recently described species associated with dry forests of central Brazil, and Celeus ochraceus, collected in its southernmost range. Furthermore, we obtained specimens that present intermediate phenotypes between the following woodcreeper species: Lepidocolaptes squamatus / L. wagleri and Xiphocolaptes albicollis / X. falcirostris. Those records reinforce the need of further sampling and collecting activities in those dry forest enclaves aiming future researches in taxonomy, geographic variation, and phylogeography.
