Larval development of Epialtus bituperculatus H. Milne Edwards, 1834 (Crustacea: Decapoda: Brachyura: Majidae) with comments on majid larvae from the southwestern Atlantic

The larval development of the spider crab Epialtus bituberculatus H. Milne Edwards which lives on rocky shores with algae such as Sargassum and Hypeneia, is described. Larvae were obtained from ovigerous females collected in Ubatuba, State of São Paulo, Brazil. Rearing was carried out at 24 ± 1°C, with an average salinity of 35%. Larval development consists of two zoeal stages and one megalopa. Zoeal development was completed in 9.5 days. Analysis indicated that zoeae of E. bituberculatus are very similar to those of E. brasiliensis Dana and Acanthonyx scutiformis (Dana). Differences noted between these species pertain to the setation of the carapace, maxillule and second maxilliped. The main morphological features useful for identification are presented together with a summary of features that characterize larvae of majid subfamilies in Brazil. A key for the identification of southwestern Atlantic majid zoeae to the family level is provided.

Phylogenetic analysis of the Neotropical social wasps of the genus Angiopolybia Araujo, 1946 (Hymenoptera, Vespidae, Epiponini)

A morphological cladistic analysis of the Neotropical swarm-founding genus Angiopolybia Araujo is presented. A single cladogram resulted from the analysis, with the following ingroup topology: (A. pallens + A. zischkai) + (A. paraensis + A. obidensis). The monophyly of the genus is supported by four synapomorphies. A new identification key is presented for the genus. Copyright © 2007 Magnolia Press.

New species of Haplometroides (Digenea: Plagiorchiidae) from Phalotris nasutus (Gomes, 1915) (Serpentes, Colubridae)

A new species of Haplometroides (Digenea, Plagiorchiidae) is described from a specimen of Phalotris nasutus (Gomes, 1915) (Serpentes, Colubridae). The host snake was obtained in the municipality of Corumbá, Mato Grosso do Sul State, Brazil. Trematodes were recovered from esophagus, stomach, and small intestine of the host. The main characteristic of the new species is the vitellaria, which is intercecal, cecal, and extracecal in the preacetabular region. A key for identification of the species in Haplometroides is proposed. © American Society of Parasitologists 2007.

A new cunaxid genus with descriptions of two new species from Brazil (Acari: Prostigmata: Bdelloidea: Cunaxidae)

The genus Pseudobonzia Smiley 1975 is revised and divided into two genera. The genus Pseudobonzia Smiley, 1975, with its type species and five other related species, is retained. The remainder of the group is now known as Coleobonzia gen. nov. of which the main characteristics are provided. Coleobonzia argillae (Den Heyer, 1977) is designated as type species for the new genus. Two species from Brazil, viz. Coleobonzia clava sp. nov. and C. moraesi sp. nov. are described and figured. A key to the two genera as well as a key to the Brazilian and South African species of the new genus are provided. Copyright © 2008 Magnolia Press.

Revision of the genus Physoclypeus Hendel, 1907 (Diptera, Lauxaniidae), with description of seven new species

The genus Physoclypeus Hendel, 1907 has its distribution restricted to the Neotropical region. In this study, its species have been redescribed, three new combinations have been proposed, three lectotypes have been designated, seven new species have been described, and an identification key to the species is presented. An updated list of species of Physoclypeus is presented as: P. annulatus Hendel, 1925; P. coquilletti (Hendel, 1908); P. farinosus (Hendel, 1925); P. flavus (Wiedemann, 1830); P. hendeli sp. nov.

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.
