Fauna of Simuliidae (Diptera) from the state of Espírito Santo, Brazil: distribution, new records and list of species

Fauna of Simuliidae (Diptera) from the state of Espírito Santo, Brazil: Distribution, new records and list of species. The fauna of Simuliidae in Brazil is composed of 87 species, 17 of which are recorded from the state of Espírito Santo. Entomological collections were carried out in 2010-2011 with the objective of increasing the knowledge of the species richness of this family in the state. Ninety three rivers and streams were sampled, each collection being carried out in a 50m transect. During the study period 30 species were collected, 13 of which represent new records for the state, 12 of the genus Simulium and one of the genus Lutzsimulium. Among these new state records one, Simulium lobatoi, also represents a new record from southeastern Brazil. The other newly recorded species are: Lutzsimulium hirticosta, Simulium distinctum, Simulium exiguum, Simulium oyapockense, Simulium botulibranchium, Simulium petropoliense, Simulium clavibranchium, Simulium rappae, Simulium minusculum, Simulium dinellii, Simulium ochraceum and Simulium scutistriatum.

New tick records in Rondônia, Western Brazilian Amazon

In the present study, we provide new tick records from Vilhena Municipality, in the Southeast of the State of Rondônia, Northern Brazil. Ticks collected from a capybara, Hydrochoerus hydrochaeris (Linnaeus), were identified as Amblyomma romitii Tonelli-Rondelli (1 female), and Amblyomma sp. (1 larva). Ticks collected from a harpy eagle, Harpia harpyja (Linnaeus), were identified as Amblyomma cajennense (Fabricius) (16 nymphs) and Haemaphysalis juxtakochi Cooley (1 nymph). Ticks collected from a yellow-footed tortoise, Chelonoidis denticulada (Linnaeus), were identified as Amblyomma rotundatum Koch (10 females, 2 nymphs), and Amblyomma sp. (2 larvae). The present record of A. romitii is the first in the State of Rondônia, and represents the southernmost record for this tick species, indicating that its distribution area is much larger than currently recognized. Although both A. cajennense and H. juxtakochi have been reported parasitizing various bird species, we provide the first tick records on a harpy eagle. A. rotundatum is widespread in the State of Rondônia, and has been previously reported on the yellow-footed tortoise. The present records increase the tick fauna of Rondônia to 26 species.

New host records and localities of some Monogenea from brazilian marine fishes with scanning electron microscopy of Bicotylophora trachinoti (Mac Callum, 1921)

Bicotylophora trachinoti (Mac Callum, 1921) from Trachinotus carolinus L.; Pseudanthocotyloides heterocotyle (Van Beneden, 1871) from Cetengraulis edentulus (Cuvier), and Decapterus punctatus (Cuvier), new host records; Pseudomazocraes selene Hargis, 1957 from Selene vomer (L.) and Caranx latus Agassiz, new host record, are reported for the first time in Brazil from the coast of Rio de Janeiro State. The marine fishes Diplectrum sp. and Pomatomus saltatrix (L.) are respectively new host records for Pseudotagia cupida (Hargis, 1956) and Macrovalvitrema sinaloense Caballero & Bravo Hollis, 1955. Measurements, original figures and photos in scanning electron microscopy of B. trachinoti are presented. The egg with filaments is reffered for the first time in the genus Pseudanthocotyloides.

Studies on Procamallanus (Spirocamallanus) pereirai Annereaux, 1946 (Nematoda: Camallanidae), with new host records and new morphological data on the larval stages

Larval stages and adults of Procamallanus (Spirocamallanus) pereirai Annereaux, 1946 are described from naturally infected Paralonchurus brasiliensis (Steindachner) (Sciaenidae) from the coast of the State of Rio de Janeiro, Brazil. The translucent first-stage larvae have a denticulate process at the anterior end, no buccal capsule or esophagus undifferentiated into anterior muscular and posterior glandular parts and an elongate tail; third-stage larvae have a tail with three terminal projections, a buccal capsule divided into an anterior portion with 12-20 ridges running to the left and a posterior smooth portion, and an esophagus with muscular and glandular regions. Fourth-stage larvae exhibit a buccal capsule lacking a distinct basal ring with ridges running to the right and a tail with two terminal processes, as in adults. New host records are reported and their role in its life-cycle are discussed.

New host records and description of the egg of Anacanthorus penilabiatus (Monogenea, Dactylogyridae)

Anacanthorus penilabiatus is referred parasitizing the type-host Piaractus mesopotamicus (Serrasalmidae) and two new hosts, Colossoma macropomum and C. brachypomum (Characidae) from fish ponds of "Departamento Nacional de Obras Contra as Secas", Pentecoste, State of Ceará, Brazil. Table of measurements and the first description of the egg are presented.

A new species of Leschenaultia Robineau-Desvoidy (Diptera, Tachinidae) from Venezuela and new geographical records

Leschenaultia barbarae sp. nov. is described from Cojedes state, Venezuela. This species is similar to Leschenaultia bicolor (Macquart, 1846) but can be distinguished from this species by the combination of the following characters: anterior tarsal claws longer than second tarsomere of the same leg, and cerci, in lateral view, finer and no so strongly curved back as in L. bicolor (Macquart).

Morphological description of the nymphal stage of Amblyomma geayi and new nymphal records of Amblyomma parkeri

The external morphology of the nymph of Amblyomma geayi Neumann is described by optical and scanning electron microscopy. Unfed nymphs were obtained from an engorged A. geayi female, which had been collected on a sloth (Bradypus variegatus) from Belém municipality, State of Pará, northern Brazil, and was kept under laboratory conditions. With the present description, we propose a modification of a taxonomic key published in 2010 for the Amblyomma nymphs that occur in Brazil, through the inclusion of A. geayi. The nymph of A. geayi is morphologically very similar to the nymph of Amblyomma parkeri Fonseca and Aragão, with only slight morphological differences related to scutal surface and punctuations (more shagreened and less punctuated in A. geayi). These 2 nymphs differ from all other known Amblyomma nymphs from Brazil by the combination of auriculae present as small posterolateral rounded projections, eyes located at the level of the scutal midlength, and a rounded hypostome. These nymphal similarities as well the morphology of the adult stage corroborate previous studies that showed that A. geayi and A. parkeri are genetically closely related. Unpublished host records of the nymphs of both A. geayi and A. parkeri are provided. Established populations of A. geayi and A. parkeri seem to be geographically separated, since all confirmed records of A. geayi are from the northern half of South America (mainly the Amazonian region) and Central America, whereas all known records of A. parkeri are from the Atlantic rainforest biome in northeastern, southeastern, and southern Brazil. © 2013 Elsevier GmbH.

NEW FOSSIL RECORDS OF PLEISTOCENE MARINE MOLLUSKS IN SOUTHERN BRAZIL

Fossils of the gastropods Diodora patagonica, Zidona dufresnei, Olivancillaria carcellesi, Lamniconus lemniscatus carcellesi and the bivalve Arcinella brasiliana are registered for the first time from the outcrops of Chui Creek, on the coastal plain of Rio Grande do Sul State, southernmost Brazil, together with other taxa previously known elsewhere. The specimens were collected in a shallow Pleistocene marine facies exposed at the base of the banks of the creek, in a fossil concentration possibly formed by storm events. The taxa described here live in shallow environments (with the exception of A. brasiliana and Z. dufresnei) with sandy bottoms (except for D. patagonica, T patagonica, B. odites, C. rhizophorae and A. brasiliana). The presence of L. lemniscatus carcellesi, found living today only in Uruguay and Argentina, indicates a wider distribution for this taxon during the late Pleistocene.

A new species and new distribution records of Pickeliana (Opiliones: Laniatores: Stygnidae)

A new species of Pickeliana Mello-Leitao,1932, P. albimaculata sp. nov, is described from Jussari, Bahia, Brazil. It can be easily distinguished from the already described species by the presence of white spots on mesotergal area I and anal opercle. It is similar to P. pickeli Mello-Leitao,1932 by the presence of a large, ventro-apical pointed tubercle on femora III-IV A cladistic analysis was performed adding a new character to the available character matrix, the presence of a large and ventro-apical pointed tubercle on male femur IV According to this analysis, P. albimaculata sp. nov is sister species of P.pickeli.Additionally,we present an identification key and an update on the geographical distribution of species of this genus in northeastern Brazil.

New pteridophyte records for the territory of Amapá, Brazil.

Eighteen Pteridophyte taxa in 15 genera are reported as new for the Territory of Amapá, Brazil. The collections area a result of a recent Projeto Flora Amazônica/Programa Flora expedition to that region, and update previous lists of taxa for Amapá.In 1975, Tryon and Conant publised a checklist of the ferns of the Brazilian Amazônia reporting 84 taxa for the Territory of Amapá. The paucity of records for Amapá reflects, at least in part, the amount of botanical exploration. The most complete list of taxa occurring in the Territory is an unpublished list of collection compiled by J. M. Pires. This compilation reports 118 taxas for the Territory of Amapá. The following list is intended to update both the Pires compilation an the Tryon and Conant checklist for the Territor. These records are the result of a Projeto Flora Amazônica/Programa Flora expedition to the region in the latter part of 1979. Species were included in this list is not reportes in the compilation of colections for Amapá, or listed as specifically occurrin in Amapá in the monographs and revisions consulted for listed as specifically occurring in Amapá in the monograohs and revisions consulted for identification (Evans, 1969; Kramer, 1957, 1978; de la Sota, 1960; Lellinger, 1972; Maxon & Morton, 1938; Scamman, 1960, Smith, 1971; Tryon, 1941, 1964).This list reports 18 taxa in 15 genera, increasing the number of taxa in Amapá from the 118 listed by Pires to 136. Most of the taxa reported here might have been predicted to occur in Amapá on the basis of their distribution records for surrounding regions.Each species is followed by a collection number. The collection number is that of D. F. Austin, C. E. Nauman, R. S. Secco, C. Rosario, and M. R. Santos except for four collections in which R. S. Secco was absent and B. V. Rabelo was present, and these are indicated after the collection number. Specimens are deposited in the herbaria of the Museu Paraense Emílio Goeldi, Belém, Brazil and the United States. The family system is essentially that used by Tyron and Conant.
