The two most striking differences between C. and other species genus is presence pairs posterior supraorbital setae elytra shape with parallel, not rounded sides. pains Álvares & Ferreira 2002 an endemic restricted to few caves at Bambuí Carbonatic Group midwest Minas Brazil. holotype was unfortunately...

Caves pose significant challenges for mining projects, since they harbor many endemic and threatened species, must therefore be protected. Recent discussions between academia, environmental protection agencies, industry partners, have highlighted problems with the current Brazilian legislation of caves. While licensing process is long, complex cumbersome, criteria used to assign caves into conservation relevance categories are often subjective, being mainly determined by presence obligate...

Anopheles (Kerteszia) cruzii has been implicated as the primary vector of human and simian malarias out Brazilian Amazon specifically in Atlantic Forest regions. The presence asymptomatic cases, parasite-positive wild monkeys similarity between parasites infecting them support discussion whether these infections can be considered a zoonosis. Although many aspects biology An. have already addressed, studies conducted during outbreaks malaria transmission, aiming at analysis blood feeding...

The degradation of subterranean habitats is believed to represent a serious threat for the conservation obligate dwellers (troglobites), many which are short-range endemics. However, while factors influencing cave biodiversity remain largely unknown, influence surrounding landscape and patterns connectivity terrestrial troglobitic communities have never been systematically assessed. Using spatial statistics analyze most comprehensive speleological database yet available tropical caves, we...

Mygalomorph spiders are rarely found in caves and most of the records appear as accidental or restricted to small populations. The present study took place iron formations Carajás region, southeastern Pará state, eastern Brazilian Amazon rainforest. Each cave was sampled twice: dry season (from May October) wet November April). Of 242 sampled, we mygalomorphs 98 (40%). survey yielded 254 specimens, 223 (87.8%) juveniles. 14 species recorded, nine were represented by adults: Dolichothele...

ABSTRACT Amblypygids are among the main predators in ferriferous caves Carajás National Forest, state of Pará (Amazon region Brazil). One most common amblypygid species this is Heterophrynus longicornis (Butler 1873), and its frequent prey crickets family Phalangopsidae, which abundant Pará. Because they primarily predators, necrophagy by amblypygids not nature, there only two literature records bats Amblypygi. On December 11th, 2013, we observed an individual H. eating a bat carcass cave....

Abstract: We provide the first report of frequency leucism for a species Neotropical bat. Leucism is an anomaly skin pigmentation animal that manifests itself as total or partial loss natural color species, and can affect part entire body. During study involving capture marking individuals population A. geoffroyi residing in cave Brazilian state Minas Gerais, seven with some degree depigmentation were recorded out 616 marked, 1.1%. Since due to recessive gene expression, these findings may...

The Amazonian genus Parastenonia Hoffman, 1977 is here revised. species P. carajas sp. nov. described from Brazilian iron-ore caves and aurae (Schubart, 1947) considered junior synonym of parae (Cook, 1895). In addition, the known geographic distribution presented with inclusion new occurrence data.http://www.zoobank.org/urn:lsid:zoobank.org:act:CCBEED10-DCB4-48C9-A71D-CED3462DD72A

Quasitagalis afonsoi gen. et sp. nov. of Saicinae (Hemiptera, Reduviidae) is described based on a male and three female specimens collected in cave the State Tocantins, Brazil. Additionally, some characteristics from two nymphs different instars same species are also recorded. An updated key to New World genera provided.

Three new species of troglobitic beetles the genus Coarazuphium are described from specimens collected in iron ore caves Flona de Carajás Brazil, doubling number known for region. The morphologically similar to already same region and distributed a small geographic range. From all region, including ones, two stand out, C. spinifemur xingu sp. nov. , which smallest species. Both have shorter legs antennae when compared others. main characteristic that differentiates xikrin kayapo other...

Here we describe three cixiid species new to science which assign the hitherto monotypic genus Ferricixius Hoch & Ferreira, 2012 from Brazil. michaeli sp. nov. and F. goliathi of are—like type davidi &Ferreira, 2012—obligately cavernicolous display varying degrees troglomorphy, such as reduction compound eyes, wings, bodily pigmentation, while urieli displays well developed eyes and—although so far only found inside caves—is ecologically classified either epigean, or subtroglophile....

Ajouts à la faune de mille-pattes d'un paysage ferrugineux amazonien: une nouvelle espèce Pseudoporatia Golovatch, 1999 répandue dans les affleurements rocheux (Diplopoda, Polydesmida, Pyrgodesmidae).

The predatory firefly Photuris elliptica is common throughout the Atlantic Forest and has been proposed as a biomonitor due to species’ narrow niche elevational range. However, species only known from adults, more effective monitoring of its populations hinges on lack knowledge their immature stages. Recent sampling in ferruginous caves inserted other lithologies, sites Cerrado, have led capture larvae later reared adults lab. Firefly reported South American before; however, they identified...
