Morphological Adaptations

The genus Listrura, Glanapteryginae, currently comprises six valid species of small and elongated trichomycterid catfishes that inhabit coastal plains of Southern and Southeastern Brazil. As primarily fossorial dwellers, species of the genus display unusual morphological adaptations and restricted habitats, which make these fishes particularly susceptible to environmental disturbance. Listrura camposi is poorly known and ranked as a Critically Endangered catfish species, according to current Brazilian list of threatened species. Description of the species was based on a single specimen collected in 1940, and for seven decades no additional specimens were reported. As a consequence, basic information about the species is unavailable. Recently, a population of L. camposi was found inhabiting a small stream tributary to rio Ribeira de Iguape basin, São Paulo State, relatively close to the type locality. On the basis of newly collected material, the species is redescribed and the first data on its habitat and ecology are presented. Conservation status is also discussed.

Ferns And Lycophytes

We present the floristic survey of ferns and lycophytes from the “Parque Estadual Turístico do Alto Ribeira” (PETAR), a remnant of Atlantic Rain Forest of Southeastern Brazil, in São Paulo state. Besides a complete list of species, we also provide information on habit, geographic distribution, and conservation status. Among the 237 taxa, there are 235 species, one variety and one hybrid, distributed in 29 families and 74 genera. Ferns are represented by 223 taxa, whereas the lycophytes were represented by 14. The most representative families are Polypodiaceae (31 spp.), Pteridaceae (29 spp.) and Dryopteridaceae (28 spp.). The most diverse genera are Thelypteris (23 spp.), Asplenium (19 spp.), Elaphoglossum and Blechnum (10 spp. each). Noteworthy is the presence of Ctenitis anniesii, Dicksonia sellowiana, Elaphoglossum iguapense, E. prestonii, E. strictum, Thelypteris concinna, T. araucariensis and T. hatschbachii, all of them considered as endangered species in São Paulo state.

Copaifera L. is a pantropical genus with great diversity in the Cerrado. Fieldwork in western São Paulo revealed the first record of C. malmei Harms in this state, and this is only the second time that this species has been found in the Southeast Region of Brazil. Additional analyses of a related species, C. marginata Benth. revealed the same rare pattern of distribution in the region. We provide morphological descriptions, comments on geographical distribution, assessment of conservation status, phenology, and an identification key to the species of Copaifera in the Cerrado in southeastern Brazil.

Listrura picinguabae, new species, is described from small tributary streams of rio da Fazenda, an isolated coastal river in Picinguaba, São Paulo State, southeastern Brazil. It is distinguished from all other trichomycterids, except L. nematopteryx, in possessing a single long pectoral-fin ray. It differs from L. nematopteryx by a combination of features including relative position of anal and dorsal-fin origins, higher number of anal-fin rays and opercular and interopercular odontodes, and morphology of the urohyal.

Size And Structure

Planning control programs, for diseases such as rabies requires information on the size and structure of the dog and cat population. In order to evaluate the dog population of the urban area of Araçatuba city, S. Paulo State, Brazil, a survey was conducted using a questionnaire to interview members of households. Eighty-eight districts were visited (37,778 houses) and the interview was possible at 77.93% of these. Human population size evaluated was 113,157 inhabitants. Houses that owned animals represented 55.2%, 26,926 of the animals concerned were dogs and 5,755 were cats. Of the dogs, 56.64% were 1-4 year olds and males represented 56.2% of the total population. Dog: person ratio was estimated at 2.8 dogs to every 10 persons, almost 3 times the ratio hitherto estimated and used in the planning of rabies vaccination campaigns.

Rineloricaria is a genus of armored catfish encompassing 67 valid species that are widely distributed throughout the Neotropical region. A new species of Rineloricaria is described from the Paranaíba River, Upper Paraná River basin, southeastern Brazil. Rineloricaria rodriquezae sp. n. is distinguished from its congeners by the combination of the following characters: caudal-fin color pattern with basal dark spot and subterminal dark bar on branched rays interspersed with a hyaline area; five series of lateral plates with two keeled in the mid-dorsal series around the insertion of the first ray of dorsal fin; and unbranched caudal-fin ray extended as long filaments.

Angraecoid Orchids

A recent large phylogenetic tree for the angraecoid orchids has shown that the Afrotropical genus Diaphananthe is polyphyletic with a small group of four species sister to Aerangis and Eurychone. These species have diagnostic morphological features different from any other angraecoids, notably an erose to fringed surface of the stipes and a calceiform viscidium. Diaphananthe quintasii, which has been regarded as conspecific with D. rohrii, is reinstated as a valid species and lectotypified, and Diaphananthe alfredii and Rhipidoglossum magnicalcar are put in synonymy under D. quintasii. To accommodate this group of species, along with three new taxa from West and Central Africa, a new genus named Kylicanthe is here described. Four new combinations are thus proposed, and K. bueae is chosen as the type species of the new genus and neotypified. Additionally, K. arcuata, K. cornuata, and K. perezverae are described as new species. An identification key for Kylicanthe and allied genera is presented, as well as one for the seven species in the genus. Notes on ecology and distribution in addition to a preliminary assessment of conservation status following the IUCN Red List are also provided.

The clinical and laboratory data of a disease in a resident of Ribeira Valley, São Paulo State, southeastern Brazil, caused by an agent close or identical to Caraparu, a Group C arbovirus, was described. Although there is evidence of an intensive circulation of several arboviruses in the area, no diagnosis of human disease by these agents has been made, except the encephalitis cases caused by Rocio virus during an epidemic in 1975-1977. An antigenic difference between Caraparu strains isolated in São Paulo and in Pará States and a close antigenic relationship between Caraparu strain from São Paulo and Bruconha virus were suggested by the serological tests.
