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.

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.

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.

El objetivo del presente estudio fue investigar la prevalencia de infestación de ectoparásitos asociados a mamíferos pequeños del Cerrado en el Parque Nacional Serra do Cipó, Estado de Minas Gerais, Brasil. De abril a septiembre de 2007, capturamos 95 mamíferos pequeños, los cuales representaron nueve especies: seis pertenecen al Orden Rodentia: Cerradomys subflavus (Wagner 1842), Nectomys squamipes (Brants 1827), Thrichomys apereoides (Lund,1939), Rhipidomys mastacalis (Lund 1840), Necromys lasiurus (Lund 1841), Oligoryzomys nigripes Olfers 1818, y tres al Orden Didelphimorphia: Gracilinanus agilis (Burmeister 1854), Marmosops incanus (Lund 1840) y Didelphis albiventris (Lund,1841). Identificamos ectoparásitos de cinco órdenes: Ixodida, Gamasida, Phthiraptera, Siphonaptera y Diptera y varias especies de ectoparasitos como: Amblyomma sp, Laelaps paulistanensis Fonseca 1936, Laelaps differens Fonseca 1936, Laelaps manguinhosi Fonseca 1936, Tur lativentralis (Fonseca 1936), Gigantolaelaps goyanensis Fonseca 1939, Gigantolaelaps vitzthumi Fonseca 1939, Androlaelaps (Haemolaelaps) fahrenholzi (Berleze 1911), Eubrachylaelaps rotundus (Fonseca1936), Mysolaelaps parvispinosus Fonseca 1936, Ctenophthirus cercomydis Ferris1922, Hoplopleura imparata Linardi 1984, Eogyropus lenti lenti Werneck 1936, Tunga penetrans (Linnaeus 1758) y Poligenes tripus (Jordania 1933). Para el parque, son nuevos todos los registros de ectoparásitos y agregamos también algunos hospederos.PALABRAS CLAVEBrasil, Cerrado, Parque Nacional Serra do Cipó, mamíferos, ectoparásitos.

Abstract A new species of harpacticoid copepod, genus Forficatocaris (F. odeteae n. sp.) is described from a high-altitude pond at the Itacolomi National Park near Ouro Preto city, Minas Gerais state, Brazil. The main characters distinguishing the new species from F. affinis Dussart, 1983 and F. lilianae Noodt, 1972 are: (i) distal portion of exopod 1 of male leg 4 with stout spinules; (ii) male leg 5 lateral spine stout and with blunt apex; (iii) endopod of leg 4 curved outwards, but “c” shaped (not forming a straight angle); (iv) female with dorsal spinule row on anal somite larger than in congeners, ventral ornaments smaller and less numerous; and (v) the shape of the modified spine located at the leg 1 endopod 1 of the male; and (vi) the spine of leg 5 in males and females.

Two New Species

Two new species of Wedelia Jacq. are described and illustrated, and their morphological affinities with other species are discussed. Wedelia pauciflora is characterized by its solitary heads and a small number of flowers per head. Wedelia homogama is recognized by its shrubby habit, homogamous discoid heads, and purple corolla. These species were collected in Serra da Canastra National Park, São Roque de Minas, and in Rio Paranaíba; both areas are at Minas Gerais State, Brazil, occurring in “Cerrado” biome.

This study describes the occurrence of the phytophilous cladoceran Celsinotum candango, which has been considered, up to now, an endemic species of the Brazilian Cerrado, with only two previous records in the wetlands of Brasilia, Federal District. The cladoceran has now been registered at Coutos Lake (“Lagoa dos Coutos”), an altitudinal, temporary shallow lake, located in ironstone outcrops at Serra do Gandarela, Minas Gerais state. This mountain ridge was recently turned into an integral protection conservation unit, the Gandarela National Park. However, many shallow lakes, including this one, were excluded from the delimited area of the park, and are now at risk of disappearing due to expansion of mining activities. The information provided here reveals the importance of these shallow lakes to aquatic biodiversity, and reinforces the need for the inclusion of these rare aquatic ecosystems into the recently created Gandarela National Park.
