A new species of Sphaenorhynchus (Anura; Hylidae) from Brazil

A new species of Sphaenorhynchus, probably closely related to S. surdus, is described from the states of São Paulo, Paraná, and Santa Catarina in the southeast and south of Brazil. This species, Sphaenorhynchus caramaschii sp. nov., is an intermediate species in size within the genus and is characterized by the absence of external tympanum, by the snout from truncate to slightly mucronate in dorsal view and protruding in lateral view, by the presence of a dark line from the snout to the eye, and mainly by differences in the advertisement call (a long call with several notes). It is found in open areas, calling during the wet season of the year, generally, in the deepest area of permanent ponds. Illustrations of the adults, descriptions of the advertisement calls, and a map of geographic distribution of the species are provided. Also, we provide data on the distribution and natural history of S. surdus and describe its advertisement call. Copyright © 2007 Magnolia Press.

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.

Description of eggs and nymphal instars of Triatoma baratai Carcavallo and Jurberg, 2000 based on optical and scanning electron microscopy (Hemiptera: Reduviidae: Triatominae)

Triatoma baratai Carcavallo & Jurberg, is a wild (i.e., nonperidomestic) species found in the State of Mato Grosso do Sul (Bodoquena region, county of Bonito), Brazil. Its eggs and nymphs are described here based on optical and scanning electron microscopy. The operculum and exochorion have pentagonal, hexagonal, and heptagonal cells, with small cracks and small random pits. Differences in the eggs and five nymphal instars of T. baratai allow them to be distinguished from the sympatric species Triatoma williami Galvão, Souza & Lima, and from six of the nine members of the Triatoma oliveirai complex. The most useful differentiating characters are in the color, shape of the abdomen, head, and total body length. Keys are provided to separate the eggs and nymphal instars of six of the nine members of the Triatoma oliveirai species complex. Copyright ©2009 Magnolia Press.

Linnaeus's plantæ Surinamenses revisited

In 1775, Jacob Alm defended the Linnaean dissertation Plantæ Surinamenses under the precidency of Carolus Linnaeus. In this account of Surinamese plants preserved in alcohol, given to Linnaeus by the King Gustavus III of Sweden, 148 species were treated, 117 of them with species names determined. Fifteen other species were indicated as new, but were neither described nor named, and 16 species were identified only to genus level. Here, the taxonomic identity and nomenclatural status of those names are updated and discussed. Five of the 117 names and also 11 of their synonyms, a species name described by Rottbøll and ten described by Linnaeus filius are lectotypified. Two new combinations and a new name are proposed, and two new synonyms are established. © 2012 Magnolia Press.

Phenotypic variation of leptodactylus cupreus caramaschi, são-pedro and feio, 2008 (Anura, Leptodactylidae)

This study describes for the first time the female of Leptodactylus cupreus and provides new information concerning its geographical distribution, male's morphology and bioacustics. Leptodactylus cupreus, a poorly known species from the Brazilian Atlantic Forest, was originally allocated in the L. mystaceus complex of the L. fuscus species group. Based on morphological observations, we infer that L. cupreus should be in fact related to L. mystacinus, a species that, although assigned to the L. fuscus species group, is not assigned to the L. mystaceus complex. Therefore, we comment the phylogenetic relationships concerning L. cupreus, L. mystaceus and L. mystacinus. © 2013 Magnolia Press.

New species of pyrrhulina (Ostariophysi: Characiformes: Lebiasinidae) from the brazilian shield, with comments on a putative monophyletic group of species in the genus

Pyrrhulina marilynae, new species, is described. The new species can be distinguished among congeners mainly by pre-senting a conspicuous, dark, zigzag shaped primary stripe, extending to distal end of median caudal-fin rays, reduction of the number of precaudal vertebrae, absence of postcleithrum 2, and nine principal rays on caudal-fin dorsal lobe. The pu-tative relationship of the new species with Pyrrhulina australis, P. vittata and P. zigzag, three small-sized species of the genus, is discussed. Copyright © 2013 Magnolia Press.

Well, what about intraspecific variation? Taxonomic and phylogenetic characters in the genus Synoeca de Saussure (Hymenoptera, Vespidae)

Cely and Sarmiento (2011) took issue with the cladistic analysis of relationships among species of the genus Synoeca by Andena et al. (2009a), and presented a reanalysis. They claimed that intraspecific variation in the genus is meaningful, and proper consideration yields a conclusion different from that of Andena et al. Both their critique and reanalysis are vitiated by numerous errors, as is shown in the present paper. © 2013 Magnolia Press.
