The pupal case of Systropus (Systropus) fumipennis is described, illustrated and photographed for the first time. A pupae was found inside an unidentified Limacodidae coocon (Insecta: Lepidoptera), and a male adult emerged, allowing the species identification.

The first stage of the fiddler crab Minuca mordax is described here. Zoea larvae obtained from four ovigerous female were reared in the laboratory until the development of the first crab stage. The development from zoea I to the first juvenile instar lasted 35 days after hatching. The first crab stage of Minuca mordax can be morphologically distinguished from those of Minuca burgersi and Leptuca cumulanta by a 2‑segmented antennule endopod (3‑segmented in M. burgersi, unsegmented in L. cumulanta), an unsegmented maxillule endopod (2‑segmented in M. burgersi and L. cumulanta), and a 4‑segmented first and second maxilliped endopod (respectively unsegmented and 5‑segmented in M. burgersi and L. cumulanta). The three species have the following characters in common: segmented peduncle of antennule 2; endopod of antennule unsegmented; presence of aesthetascs on the antennule; peduncle of antenna 3‑segmented; flagellum of antenna 6‑segmented; mandible 3‑segmented; maxilla with coxal and basal endite bilobed; first, second and third maxillae with exopod 2‑segmented and abdomen with six somites that are wider than long.

In this report, we record the rediscovery of Sanderia malayensis in Pakistani waters since the John Murray Expedition (1933‑34) who collected two small specimens off-Karachi, Pakistan. The specimens were described and we discuss the shape of gastric pouches contour. We also comment upon the newly recorded Rhopilema nomadica jellyfish from the region, and assume it to be previously recorded as Rhopilema hispidum.

The humpback whale (Megaptera novaeangliae) is distributed among most oceans and seas of the globe (except Mediterranean Sea). These whales migrate from feeding regions in the Antarctic waters to breeding areas in tropical and subtropical seas. Here we report the stranding of a female young humpback whale, which was founded dead in the vicinity of the Talavera Island, in the Paraná River Delta, Buenos Aires Province, Argentina. From the analysis of mitochondrial cytochrome c oxidase subunit I gene sequences, two novel haplotypes were found, totalizing four haplotypes described for the species. In the La Plata River Basin this species was found only twice at the end of the XIX century. Thus, the new finding constitutes an important addition to the list of cetaceans that occurs in Uruguay, Paraná and La Plata Rivers.

The following 13 new replacement names are proposed for junior secondary homonyms: Jurinella neobesa, new name for Jurinella obesa (Townsend, 1928) (preocc. Wiedemann, 1830); Archytas wulpianus, new name for Archytas nigrocalyptratus (Wulp, 1888) (preocc. Macquart, 1846); Calodexia neofumosa, new name for Calodexia fumosa (Townsend, 1917) (preocc. Townsend, 1912); Calodexia bigoti, new name for Calodexia flavipes (Bigot, 1889) (preocc. Schiner, 1868); Eucelatoria paracarinata, new name for Eucelatoria carinata (Townsend, 1927) (preocc. Townsend, 1919); Eucelatoria currani, new name for Eucelatoria carinata (Curran, 1926) (preocc. Townsend, 1919); Lixophaga opsiangusta, new name for Lixophaga angusta (Townsend, 1927:294) (preocc. Townsend, 1927:284); Lixophaga thompsoniana, new name for Lixophaga fumipennis (Thompson, 1968) (preocc. Townsend, 1927); Lixophaga townsendiana, new name for Lixophaga fumipennis (Townsend, 1928) (preocc.

Townsend, 1938). And the two following synonymies are proposed (reinstated): Jurinella ambigua (Macquart, 1851) = Jurinella obesa (Wiedemann, 1830); and Archytas analis (Macquart, 1843) = Archytas analis (Fabricius, 1905).

The broad-shouldered water strider Paravelia cunhai sp. nov. is described and illustrated based on material from the state of Pará, northern Brazil. The new species can be distinguished from all other species in this genus mainly by the dark color of the head and pronotum, absence of pruinosity or silvery pubescence on the anterior lobe of pronotum, maculae pattern on the fore wings, hind femur with row of 22 spines on mesal margin, and general shape of the paramere. This new species was collected in a pool inside a cave without incident light, a habitat recorded for the genus only recently, which reinforces the hypothesis that some species of Paravelia have troglophilic habits. In addition, a photograph of the dorsal habitus and notes concerning P. juruana Polhemus & Polhemus are provided, and P. cupariana Polhemus & Polhemus syn. nov. is proposed as a junior synonym of P. spinifera Polhemus & Polhemus.

Trap-nesting bee and wasp inventories are common in Brazil but many phytophysiognomies are still poorly studied. The main objective of this study is to survey trap-nesting bees and wasps in a Semidecidual Seasonal Forest fragment. Also, we test the differences on nesting between interior and edge transects. A sum of 1,500 trap nests was made with bamboo cane internodes and two consecutive years were monitored. In the first year 46 nests were occupied by Pachodynerus grandis (19 nests), Pachodynerus guadulpensis (19), Centris analis (two), and Centris tarsata, Megachile fiebrigi, Megachile guaranitica, Megachile susurrans, Trypoxylon sp and Zethus smithii with one nest each. No statistical differences were found between interior and edge transects for richness and occupation rate, but the species composition was different. In the second year 39 nests were occupied by four species, three previously recorded, C. analis (seven nests), P. guadulpensis and P. grandis (six nests each), plus Monobia angulosa with 15 nests. Parasitoids from four families and one cleptoparasite were recorded and the mortality rate was higher in bees than in wasps. These findings reinforce the notion that trap nests assemblages from different studies are not directly comparable for richness and composition.

Abstract. Insect galls of the Floresta da Cicuta (Volta Redonda, RJ, Brazil). Galls are changes in the pattern of growth and development of plant tissues or organs in response to the action of an inducing organism, usually an insect. The goal of the present study was to inventory the insect galls of the Floresta da Cicuta (Volta Redonda, RJ, Brazil). The collections were carried out along all the trails, totaling 16 hours of sampling. Forty-three morphotypes of insect galls were found in 24 plant species (18 genera and 15 families). Sapindaceae and Euphorbiaceae were the most richness host plant families. Six new records of host plant species are presented: Senefeldera verticillata (Vell.) Croizat. (Euphorbiaceae), Inga acuminata (Fabaceae), Ocotea elegans (Lauraceae), Ouratea stipulata (Ochnaceae), Psychotria nuda (Rubiaceae) and Cestrum intermedium (Solanaceae). Most of the galls occurred on leaves (n = 21) and stems (n = 18), followed by buds (n = 2), two gall morphotypes occurred simultaneously on leaves and stems. One-chambered galls were more frequent (n = 31), as well as glabrous galls (n = 33). The gallers belong to three insect orders: Diptera (Cecidomyiidae), Hemiptera, and Lepidoptera. The associated fauna comprised parasitoids (Hymenoptera), inquilines (Hemiptera and Coleoptera) and successors (Isoptera and Acari).

Studies about diet of birds in Atlantic Forest are scarce. In this study, we characterized the diet of Passeriformes from the south coast of Espírito Santo State, Brazil, classifying them into trophic guilds. From 26 species a total of 94 samples were obtained by regurgitation using tartar emetic method. The 855 items found were separated into two different categories: Insects (includes other terrestrial arthropods, such as spiders and opiliones) and Fruits/Seeds. The most frequent food item was Coleopterans, and the most abundant was Hymenoptera.

Representativity of the genus Asphondylia Loew, 1850 (Diptera, Cecidomyiidae) in Brazil. This cosmopolitan genus includes 272 galling species described, of which about 100 occur in the Neotropical Region. The present study goal to evaluate the richness of Asphondylia in Brazil, to provide an updated list of the host plant species, to determine the plant organs where galls are induced, to update the geographic distribution of the genus, to verify it distribution in the Brazilian biomes, and to the list the associated fauna. The survey data was carried out by consulting the Cecidomyiidae collection of the Museu Nacional/UFRJ, the database “Web of Science” using Asphondylia and Brasil/Brazil as keywords, 51 Brazilian inventories and two catalogues. Asphondylia is represented by 58 species in Brazil, among them, twenty are already known and 38 are still undetermined. The Brazilian described species represent 8% of the total of known species of Asphondylia in the world and 21% of species of the Neotropical fauna. This genus is associated with 51 plant species and 20 plant families in Brazil. Asteraceae comprise the greatest richness of Asphondylia species. This genus was found in five biomes, among them the Atlantic forest has the highest species richness. The associated fauna comprises parasitoids (Hymenoptera) and inquilines (Lepidoptera, Coleoptera and Diptera).

This catalogue lists types of three ant subfamilies (Dolichoderinae, Formicinae and Martialinae) housed in the Formicidae Collection of the Hymenoptera Laboratory, Museu de Zoologia da Universidade de São Paulo (MZSP), Brazil. It provides label information, morphological condition of specimens, nomenclatural changes, and type status, following recommendations of the International Code of Zoological Nomenclature (ICZN). Here we present information on types of 101 nominal species, of which 96 are still valid. Eight species are only represented by holotypes, 27 species only by paratypes, seven by holotypes and paratypes, 56 species by syntypes, two species by paralectotypes and one species by a lectotype and paralectotypes. With this issue we complete the publication of information regarding all MZSP ant types, summing 4,741 specimens of 892 nomenclaturally valid species.

Gynandromorphism is the most common case of sexual anomaly reported in bees and is characterized by individuals that show male and female traits simultaneously in the body. Gynandromorphic cases have been reported for 140 species of bees, an underestimated number comparing to the twenty thousand bee species described nowadays. Here we describe and illustrate the first case of a gynandromorphic Xylocopa darwini Cockerell, 1926 and the fourth case of Xylocopa varipuncta Patton, 1879. The specimens show a mixed form of gynandromorphism with predominantly female features and with all its male traits concentrated in one side of the body, right side in X. darwini and left side in X. varipuncta. The gynanders of X. darwini and X. varipuncta were collected on Isabela Island (Galapagos – Ecuador) and Riverside (California – USA), and were deposited in Smithsonian Collection and California Academy of Sciences, respectively. Including this work, eighteen cases of gynandromorphism were reported to Xylocopa and twelve were recorded from Neoxylocopa subgenus.

The remoteness of the Trindade and Martin Vaz young volcanic archipelago (TMV) raises questions about the source of its marine benthic fauna and levels of endemism. Addressing these questions requires a comprehensive knowledge of the taxonomic composition of the marine fauna of the islands. A five-year survey in the shallow marine waters (up to 30 m) and a literature review on the data published for TMV have been conducted to document the biodiversity of the benthic fauna. Here we report on ten new records of decapod crustaceans from TMV: Gnathophyllum americanum and Thor amboinensis are circumtropical in distribution, whereas Stenopus hispidus, Gnathophylloides mineri and Parribacus antarcticus are disjunct circumtropical species as their distribution in the Atlantic Ocean is limited eastwardly to TMV or Ascension Island (S. hispidus), therefore, do not extending into the eastern Atlantic. Gnathophyllum circellum and Thor manningi are western Atlantic species, with G. circellum previously known only from the Caribbean Sea. Pontonia manningi, Tuleariocaris neglecta and Enoplometopus antillensis are amphi-Atlantic in distribution. Two of the above species are recorded from the southwestern Atlantic for the first time: Gnathophyllum circellum and Tuleariocaris neglecta. These new records corroborate that the marine benthic invertebrate fauna of the TMV archipelago is actually a mosaic of amphi-Atlantic, eastern Atlantic, central Atlantic (insular), endemic and circumtropical species, with a strong western Atlantic component.

We reviewed the occurrences and distributional patterns of migratory species of birds in Brazil. A species was classified as migratory when at least part of its population performs cyclical, seasonal movements with high fidelity to its breeding grounds. Of the 1,919 species of birds recorded in Brazil, 198 (10.3%) are migratory. Of these, 127 (64%) were classified as Migratory and 71 (36%) as Partially Migratory. A few species (83; 4.3%) were classified as Vagrant and eight (0,4%) species could not be defined due to limited information available, or due to conflicting data.

Exocrine glands play important role in social organization of insects, such as caste and inter-caste differentiation. Due their functional and structural plasticity, morphological studies on such glands contribute to better understanding the biology of social bees. Therefore, the aim of the study was to characterize the sequence of the post-embryonic development of intramandibular glands of Friesella schrottkyi (Friese, 1900) (Hymenoptera: Apidae) workers using histological and histochemical analyses. The mandibles of pupae at different developmental stages and newly emerged adults were analyzed. The intramandibular glands of F. schrottkyi presented two types: class I glands, in the mandible epidermis and class III glands, inside the mandible cavity that open onto external surface. The intramandibular glands of F. schrottkyi developed during the transition from the prepupae to the white-eyed pupae, as shown by the morphological changes. Black-eyed pupae of F. schrottkyi presented fully developed intramandibular glands.

In this study we perform an inventory of the insect galls in savanna and forest sites of Hidrolândia, Goiás, Brazil. We found 150 insect gall morphotypes, distributed on 39 botanical families and 104 plant species. Among the insect galls, 81 gall morphotypes were recorded in the savanna site and 73 in the forest site. The plant taxa richest in insect galls were the family Fabaceae with 22 gall morphotypes, the genus Bauhinia (Fabaceae) with 15, and the species Siparuna guianensis (Siparunaceae) with seven gall morphotypes. We found gall-inducing insects belonging to orders Diptera, Coleoptera, Lepidoptera and Thysanoptera. The galling insects of family Cecidomyiidae (Diptera) were the most common inducing 48.1% of the gall morphotypes. This is the first systematic survey of insect galls realized in the city of Hidrolândia, being this the site with the higher insect gall diversity already cataloged to the Central region of Brazil.

IUCN Red Lists have been a valuable tool to prioritize conservation plans in endemic neotropical frogs. However, many areas in this region are poorly known in terms of their diversity and endemism. Based on examined museum specimens of the threatened species Pristimantis penelopus we revised its geographic distribution and determined the habitat suitability using niche modeling techniques. Using a mitochondrial fragment of COI gene, we determine the phylogenetic position and the extent of the genetic variation across its distribution in Colombia. We present the first records of P. penelopus for the Cordillera Oriental, the western versant of Cordillera Occidental and the northern portion of the Cauca river basin. Based on the molecular phylogenetic analysis, Pristimantis penelopus belongs to the P. ridens series sensu Padial et al. (2014). The mean of intraspecific genetic variation is 2.1% and the variation among population ranges between 2.3 and 3.5%. The genetic distance between the western populations and the Magdalena Valley populations suggests a potential phylogeographic break in northwestern Antioquia. We expand the realized distribution by 258 kilometers north, 200 km east and 223 km northwest. Based on our results and according to the IUCN criteria we propose a new category for the species and highlight the need to increase the surveys in poorly known regions to better understand the geographic distribution and conservation status of listed species.

Two new species of Dasyhelea Kieffer, Dasyhelea jorgei Diaz, Felippe-Bauer & Spinelli sp. nov. and Dasyhelea mineira Diaz, Felippe-Bauer & Spinelli sp. nov. are described, illustrated and photographed from Peru and Brazil respectively, based on male and female adults. These species are typical members of mutabilis species group and are compared with similar species within the group.

The first record of the Neolicaphrium recens Frenguelli, 1921 (Mammalia, Litopterna) from Pleistocene deposits of the Río Dulce, Rio Hondo Department, Santiago del Estero Province, Argentina, is reported. The morphology and morphometry observed in the specimen MPAT073 is coincident with the diagnostic characteristics of that species. This finding represents the northernmost and westernmost record of the species, and thus extends its geographical distribution. Geological data suggest that the material comes from a still unnamed Pleistocene stratigraphic unit.
