Steinernema brazilense n. sp (Rhabditida: Steinernematidae), a new entomopathogenic nematode from Mato Grosso, Brazil

A new entomopathogenic nematode, Steinernema brazilense n. sp., was isolated from a single soil sample collected from a natural forest in Mato Grosso do Sul state, Brazil. S. brazilense n. sp. is characterized morphologically by features of infective juveniles (IJ), males and females. For the IJ, body length averaging 1157 (1023-1284) mu m, distance from anterior end to excretory pore 95 (87-102) mu m, from anterior end to end of esophagus 148 (139-153) mu m, tail length 85 (80-104) mu m, D% and E% values 63 (58-70) and 106 (95-118.0), respectively. Lateral field pattern variable; the formula for the arrangement of ridges from head to tail is: 2, 4, 6, 8, 6, 2. For the male, the diagnostic characters include spicule averaging 83 (75-89) mu m; D% about 65; the ratio SW% about 192. The length of spicule head is greater than width. Lateral field with one narrow ridge. First generation females are characterized by the presence of a ventral postanal swelling. S. brazilense n. sp. is morphologically close to Steinernema diaprepesi. It can be differentiated from S. diaprepesi by its longer IJ body length (1157 vs 1002 mu m), longer distance from anterior end to excretory pore (1110 vs 75 mu m), a longer tail length (103 vs 83 mu m); males of the new species with longer spicule (83 vs 79 mu m). The new species can be distinguished further from other members of Steinernema glaseri group by characteristics of rDNA of ITS and D2D3 regions. Published by Elsevier B.V.

A new Moenkhausia Eigenmann, 1903 (Ostariophysi: Characiformes) from Chapada Diamantina, rio Paraguaçu Basin, Bahia, Northeastern Brazil

Moenkhausia diamantina, nova espécie, é descrita de tributário do rio Paraguaçu, BA, nordeste do Brasil. Esta espécie é distinguida das demais congêneres por caracteres relacionados ao padrão de coloração do corpo, pela presença de escamas na linha mediana pré-dorsal e número de raios da nadadeira anal.

A new frog of the genus Hylodes (Amphibia : Leptodactylidae) from Minas Gerais, Brazil

A new species of leptodactylid frog is described from Parque das Mangabeiras, in Belo Horizonte, Minas Gerais, south-eastern Brazil. The new species is a member of the Hylodes lateristrigatus group, and is characterized by medium size, snout rounded in dorsal view and protruding in lateral view, presence of vocal slits and sacs, upper surface of finger and toe discs with well-developed scutes, a weakly developed stripe on the upper lip, dorsum, arm, leg, and foot dark brown with small irregular brown and black dots, and absence of red and yellow spots in live specimens. The descriptions of the tadpoles and vocalizations, and information on natural history are provided. Hylodes perplicatus (Miranda-Ribeiro), previously considered a member of the H. nasus species group, is transferred to the H. lateristrigatus species group.

Hyphessobrycon rutiliflavidus n. sp., a new characid fish from the upper rio Paraguai, State of Mato Grosso, Brazil (Characiformes : Characidae)

Hyphessobrycon rutiliflavidus, new species, is described from the upper rio Paraguai in Cuiaba, State of Mato Grosso, Brazil. The new species differs from all other congeners by the following combination of characters: black humeral spot, slightly diffuse at its tips, and caudal-peduncle blotch present; midlateral body stripe conspicuous in its posteriormost portion, extending to the tips of the middle caudal rays; anal fin with iii, 15 to iv, 19 rays (mode iv, 17); upper jaw length, 42.3 to 49.5% of the head length; maxilla with 2-5 teeth (mode 3); all the fins of males reddish-orange and of females yellowish.

A new Hemigrammus Gill from upper rio Parana system, Southeastern Brazil (Characiformes : Characidae)

Hemigrammus parana is described from the upper rio Parana system, in the area of influence of the Ilha Solteira reservoir in states of Mato Grosso do Sul, Minas Gerais and São Paulo, southeastern Brazil. The new species differs from all congeners by the combination of the following characters: absence of humeral spot; presence of a roughly triangular or rectangular conspicuous black caudal spot, extending from base to tip of middle caudal-fin rays, its greatest depth at base of caudal-fin rays; and anal-fin rays iii-iv, 18-23.

Description of Leishmania (Leishmania) forattinii sp. n., a new parasite infecting opossums and rodents in Brazil

A new parasite species of Leishmania is described, L. (Leishmania) forattinii sp. n., which was isolated from a pooled triturate of liver and spleen of a opossum (Didelphis marsupialis aurita) and from skin samples from a rodent (Proechmys iheringi denigratus), captured in primary forest on the Atlantic Cost of Brazil. Our results on the basis of biological and molecular criteria indicate that this taxonomically distinct parasite ias a new species of the L. mexicana complex, but closely related to L. (L.) aristidesi Laison & shaw, 1979, as revelated by phenetic and phylogenetic numerical analyses of the enzyme data. L. forattinii was clearly distinguishable from other Leishmania species of the genus usisng enzyme electrophoresis, monoclonal antibodies, molecular karyotypes, analysis of restriction enzyme digestion patterns of kinetoplast DNA (kDNA), as well as the use of kDNA hybridization procedures.

STICHOSIPHON-MANGLE SP-NOVA, A NEW CYANOPHYTE FROM MANGROVE ENVIRONMENTS

A new species of epiphytic Cyanophyceae, Stichosiphon mangle, is proposed. It differs from S. sansibaricus in the planes of cell division during exocyte formation and the habitat. Stichosiphon mangle was found on Inhaca Island, Mozambique (26-degrees-03'S, 32-degrees-57'E), growing up on Gelidium sp. and Murrayella sp. and on Cardoso Island, Brazil (25-degrees-10'S, 48-degrees-W, on Bostrychia spp.
