Rediscovery of the syntypes of Corydoras meridionalis R. von Ihering, 1911 (Teleostei, Siluriformes, Callichthyidae) and designation of lectotype

Os síntipos de Corydoras meridionalis Rodolpho von Ihering, 1911, tidos como desaparecidos da coleção de peixes do Museu de Zoologia da USP, foram encontrados; os exemplares tinham sido identificados como C. ehrhardti Steindachner, 1910, espécie atualmente considerada sinônimo sênior da primeira. O exame desses sintipos permite confirmar a sinonímia proposta. Dados sobre os síntipos são apresentados e comparados com os dados das descrições originais de C. ehrhardti e C. meridionalis, sendo comentadas as poucas diferenças encontradas entre eles. É designado o lectótipo de C. meridionalis e uma fotografia deste é apresentada.

The taxonomic status of Phlebotomus oliverioi (Diptera, Psychodidae) and a lectotype designation for Psathyromyia brasiliensis

Phlebotomus oliverioi Barretto & Coutinho, 1941 was originally described based only on the male holotype and has since been considered junior-synonym of Psathyromyia brasiliensis (Costa Lima, 1932). The study of the holotype of Ph. oliverioi allowed us to conclude that the head of this specimen belongs to the genus Psychodopygus and the wings, thorax and abdomen belong to a different species of Psathyromyia. Thus, Ph. oliverioi is a not valid species, and must be removed from the synonym and excluded from the provisions of the International Code of Zoological Nomenclature (Articles 17.2 and 23.8). The specimen was measured, drawn, photographed and the morphological characters are discussed. Lectotype and paralectotypes to Pa. brasiliensis are designated.

Revisão taxonômica de Leptolobium (Papilionoideae, Leguminosae)

This revision of Leptolobium Vogel includes an identification key, descriptions, illustrations, and distribution maps for the taxa. Leptolobium comprises 12 species, and is characterized by its arboreal or shrubby habit, flowers with white, actinomorphic or slightly zygomorphic corollas, 10 free stamens, a stipitate ovary with many ovules, indehiscent (samara-like or nut-like) fruits, compressed seeds, and a bulbose hypocotyl-radicle axis. Leptolobium is a neotropical genus that occurs from Mexico to northern Argentina. Eleven species are found in Brazil, seven of which are endemic to the country. The lectotype of Sweetia glazioviana Harms is designated in this paper. In addition, information about uses, common names, geographical distribution, and habitats are provided.

Catalogue of " poneromorph" ant type specimens (Hymenoptera, Formicidae) deposited in the Museu de Zoologia da Universidade de São Paulo, Brazil

The present catalogue lists the type specimes of 112 nominal " poneromorph" ant species housed in the Formicidae collection of the Hymenoptera laboratory, Museu de Zoologia da Universidade de São Paulo (MZSP). The catalogue includes types of Amblyoponinae, Ectatomminae, Heteroponerinae, Ponerinae, and Proceratiinae, that is, all poneromorph (sensu Bolton, 2003) but for the monotypic Paraponerinae, of which the collection bears no type specimens. We present here information on type categories (holotype, paratype, syntype, lectotype, and paralectotype), label data, nomenclatural changes since the original description and type specimens conservation status. At last we present indexes for the taxa names presented.

Redescription of Hiatella meridionalis d'Orbigny, 1846 (Mollusca, Bivalvia, Hiatellidae) from Argentina

The redescription of Hiatella meridionalis (d’Orbigny, 1846) is provided as first attempt to improve the systematics of the genus in the regions of Atlantic and western Pacific. This reanalysis is based on specimens collected in the vicinity of the type localities and is based on detailed morphology of samples that some researches consider a single, wide ranging species. From the morphological characters, the more interesting are: a high quantity of papillae at incurrent siphon; the retractor muscles of siphon divided in two bundles; the small size of the palps; the muscular ring in the stomach; and the zigzag fashion of the short intestinal loops. These characters distinguish the species from the other hiatellids so far examined. Type material of the species was examined, by first time illustrated, and the lectotype is designated.

Trichopeltariidae (Crustacea, Decapoda, Brachyura), a new family and superfamily of eubrachyuran crabs with description of one new genus and five new species

A new family, Trichopeltariidae, is proposed to accommodate Sphaeropeltarion edentatum, new genus and species, and four additional genera traditionally placed in the family Atelecyclidae: Trichopeltarion A. Milne-Edwards, 1880 (type genus); Peltarion Hombron & Jacquinot, 1846; Podocatactes Ortmann, 1893; and Pteropeltarion Dell, 1972. Additionally, four new species of Trichopeltarion are described and illustrated. The new family exhibits characters of neither superfamilies of the Section Eubrachyura and is assigned to its own superfamily, Trichopeltarioidea nov. Keys to the genera of Trichopeltariidae fam. nov. and to all species in the family are presented (species of Trichopeltarion excepted). Six new combinations are proposed or confirmed. The genus Krunopeltarion Števčić, 1993, is merged into the synonymy of Trichopeltarion. A lectotype is selected for Trichopeltarion corallinum (Faxon, 1893).

Revision of the Neotropical trahiras of the Hoplias lacerdae species-group (Ostariophysi: Characiformes: Erythrinidae) with descriptions of two new species

Hoplias lacerdae was originally described from the rio Ribeira de Iguape, Iporanga, São Paulo State. The Hoplias lacerdae group is defined as containing generally large trahiras with the medial margins of dentaries running parallel to each other and lacking teeth on the basihyal compared to the H. malabaricus group in which the medial margins of the dentaries converge towards the mandibular symphysis and which have teeth on the basihyal. A taxonomic revision of the group based on meristic and morphometric data identified five distinct species: H. lacerdae distributed in the rio Ribeira de Iguape and rio Uruguai; H. intermedius from the rio São Francisco, upper rio Paraná basin, and rio Doce; H. brasiliensis from rivers of the Atlantic Coastal drainage from the rio Paraguaçu to the rio Jequitinhonha; H. australis new species, endemic to the rio Uruguai; and H. curupira new species present in northern South America, including the rios Negro, Trombetas, Tapajós, Xingu, Tocantins and Capim in the Amazon basin, upper rio Orinoco near the rio Casiquiare (Venezuela), and coastal rivers of Guyana and Suriname. A lectotype for Hoplias intermedius and a neotype for H. brasiliensis are designated.

Phylogeny and Taxonomy of the Neotropical Thepytus (Lepidoptera: Lycaenidae: Theclinae)

The Neotropical lycaenid hairstreak genus Thepytus Robbins and its eight species are revised. Species treatments summarize nomenclature, distribution, habitat, behavior, and diagnostic traits, as well as noting why each species is considered distinct under a biological species concept. An identification key for males and a checklist are included. Beatheclus Balint & Dahners new synonym is synonymized with Thepytus, and Theppus beatrizae (Balint & Dahners) is a new combination. Other nomenclatural actions include the description of Thepytus jennifer Busby & Robbins new species. Thepytus nancyana Busby & Robbins new species, and Thepytus carmen Robbins & Duarte new species. A lectotype is designated or Thecla thyrea Hewitson, 1867, to ensure stability of this name. A phylogenetic analysis based on 22 coded morphological characters yields one equal weight most parsimonious 39-step tree. Implied weighting does not change the tree topology. Unambiguous changes in elevation optimized on the cladogram show that a montane lineage of Thepytus colonized the lowlands in at least one instance. The use of T. echelta (Hewitson) as a biological control agent for Psittacanthus (Loranthaceae) is discussed.

Generic classification for the Gasteruptiinae (Hymenoptera: Gasteruptiidae) based on a cladistic analysis, with the description of two new Neotropical genera and the revalidation of Plutofoenus Kieffer

Gasteruptiinae is the largest Gasteruptiidae subfamily, with circa 400 species that have been grouped into the worldwide Gasteruption Latreille. Based on a cladistic analysis with 43 morphological characters, 40 ingroup taxa representing all biogeographic regions, and seven outgroups (four Hyptiogastrinae, two Aulacidae and one Evaniidae), I confirm the monophyly of Gasteruptiinae and Gasteruption and recognize three exclusively Neotropical small genera: Plutofoenus Kieffer (revalidated) (southern South America), Spinolafoenus Macedo n. gen. (Chile) and Trilobitofoenus Macedo n. gen. (Central and South America). Gasteruption, supported by four synapomorphies, remains the most speciose genus in the subfamily. The four Gasteruptiinae genera are keyed and described. Seven species are keyed and described or redescribed: Plutofoenus chaeturus (Schletterer) n. comb., P. edwardsi Turner, P. paraguayensis (Schrottky), Spinolafoenus ruficornis (Spinola) n. comb., Trilobitofoenus alvarengai Macedo n. sp., T. plaumanni Macedo n. sp. and T. sericeus (Cameron) n. comb. (lectotype designated).

Phylogenetic revision of the flightless Australian genus Apterotheca Gebien (Coleoptera : Tenebrionidae : Coelometopinae)

Members of the flightless genus Apterotheca Gebien (Coleoptera : Tenebrionidae) are mostly restricted to the high elevation rainforests of the Wet Tropics World Heritage Area of north-eastern Australia. This region has been recognised as an 'epicentre of evolution for low vagility animals'. The genus Apterotheca is the most diverse low vagility insect taxon known in this region. Forty-four species are included here in a revision of the genus. Three of these species were previously included in Apterotheca (A. antaroides (Pascoe), A. besti (Blackburn) and A. punctipennis Carter), four were previously included in other genera (A. australis (Kulzer), comb. nov. and A. punctifrons (Gebien), comb. nov. in Apterophenus Gebien, A. costata (Buck), comb. nov. in Caxtonana Buck and A. pustulosa (Carter), comb. nov. in Austropeus Carter) and 37 are new. The monotypic genera Austropeus Carter, syn. nov. and Caxtonana Buck, syn. nov. are proposed as new synonyms of Apterotheca. A lectotype for A. punctipennis and A. besti are designated. A key to the species of Apterotheca and a phylogenetic analysis based on the morphological features of adults, as well as a discussion of character evolution, are also included. Data presented here represent the framework for future studies on the determinants of the patterns of diversity found in the Wet Tropics.

Revision of the Chilean species of Empididae (Diptera) described by J. Macquart

Four Chilean species of Empididae (Diptera) are revised: Aplomera pachymera (Macquart, 1838), A. gayi Macquart, 1838, Empis nudipes Macquart, 1838 and E. polita Macquart, 1838. Aplomera chilensis (Bezzi, 1909) was also studied and it is being considered junior synonym of A. pachymera. Empis nudipes Macquart, 1838 is confirmed to be a junior synonym of A. gayi Macquart, 1838. Lectotype is being designated for A. pachymera, A. chilensis and E. polita. Illustration of terminalia and photomicrographs of wings are also included.

Taxonomic notes on the genus Pseudodynerus (Hymenoptera, Vespidae, Eumeninae)

The differences between Pseudodynerus auratoides (Bertoni, 1918) and Pseudodynerus serratus (Fox, 1902) are established. Lectotypes of Stenodynerus mondaiensis Bertoni, 1918 and Stenodynerus auratoides Bertoni, 1918 are designated. Pseudodynerus penicillatus (Zavattari, 1912) is redescribed and newly raised from synonymy under P. serratus (Fox, 1902).
