| Porphyrosela minuta Clarke is a gracillariid that causes damage on white clover (Trifolium repens) in Uruguay. In this article, the eggs, all the larval instars, the pupa and the external morphological characteristics of the adult are described. Information about the insect's biology under laboratory and field conditions is presented. The eggs are laid singly on the upper surface of the leaflets. The larvae make extensive mines that appear as white blotches. The larvae develop through five instars and do not remain exposed during their development. At 25ºC the life cycle lasted 16.2 days, made up of 3.0 for eggs, 8.8 for larvae and 4.4 for pupae. Females began laying on the first night, and during an oviposition period that varied between five and 12 days... |

| A new genus, Podkova, is described from Brazil to accommodate its type-species P. hirsuta, sp. n. The genus has a peculiar appearance, the main features of which are the small compact body with coarsely pilose dorsal parts of the head and mesosoma, including median part of propodeum, head with sharp frontal carina of horse-shoe shape, delimiting broad facial cavity with rather short antennae, and a sharp occipital carina stretching posteriorly down along hind margins of eyes. By these features, Podkova resembles the genus Alachua Schauff and Boucek, but differs distinctly by having strong frontal carina on the head and the prepectus hardly overlapped by the anterior margin of mesosternum. Possible affinities to some other entedonine genera are discussed. |

| Notes on Neotropical Eumeninae, with the description of a new species of Pachodynerus de Saussure (Hymenoptera, Vespidae). Taxonomic information on Neotropical Eumeninae is provided. A new species, Pachodynerus fessatus sp. nov. is described from southeastern São Paulo, Brazil. Additional material of Pachodynerus sericeus (Fox) was examined, representing the first further specimens after the original description and including the previously unknown male. The examination of new material of the genus Stenonartonia adds some new distribution records and shows some previously unrecorded individual variation for some species. The males of Stenonartonia guaraya Garcete-Barrett and Stenonartonia rejectoides Garcete-Barrett are described for the first time. |

| ABSTRACT A new species of the genus Anopheles Meigen (Diptera: Culicidae), Anopheles (Nyssorhynchus) striatus n. sp., preliminary designated as Anopheles CP Form, from Brazil, is here validated and described using morphological characteristics of the egg, fourth-instar larva, pupa, female and male genitalia. The species is morphologically more similar to species of the Strodei Subgroup of Anopheles (Nyssorhynchus) than to any other species of the subgenus Nyssorhynchus Blanchard. However, adult female that can be misidentified with Anopheles (Nyssorhynchus) galvaoi Causey, Deane & Deane if the identification is mainly based on the ratio of dark and white scales of the hindtarsomere 2. In addition, the characterization of the new species includes... |

| Abstract Due to the lack of studies comparing Syzygium malaccensis(L) Meer e Perry, Syzygium aqueum Burm.f. and Syzygium jambos (L) Alston Syzygium in relation to the botanical genus Sygygium regarding the physical characteristics, the present research was conducted, aiming at biometrically characterizing each of the three species, as well as comparing them. The fruits were collected from the São Paulo State University (Unesp), School of Agricultural and Veterinarian Sciences, Jaboticabal. Syzygium plants were used for the evaluation of: fruit and seed masses (g); width and length of leaves (cm) and of seeds (cm); percentage of fruit pulp; length of leaf petiole (cm); and leaf area (cm2). Fifty fruits, leaves and seeds of each species were used, with 5... |

| A new species of Helochares Mulsant, 1844 (Hydrophilidae: Acidocerinae) from Brazil is described and illustrated. Helochares (s. str.) atlanticus sp. nov. is distinct mainly by characteristics of the aedeagus whose phalobase is short, narrowed on basal third; parameres are thick, constricted on apical quarter, with small tooth-like projection on outer margin near apex; dorsal lobe longer than ventral lobe, shorter than parameres, very wide at base, abruptly narrowing toward apex until about half of its length where it dilates and divides into two long and narrow projections apart from each other at base, but turned inward at apex; ventral lobe acuminate and symmetrical. The rounded emargination on anteromedial margin of labrum bearing small tooth-like... |

| A new species of Oeda Amyot & Serville, 1843 - Oeda (Oeda) mielkei sp. nov. from Peru, Madre de Dios, 12°52'S, 71°22'W - is described. It differs from the other species of O. (Oeda) in having the inflated pronotal process more elongate, and amber color; the suprahumeral horns are much more developed, club-shaped, about as long as the width of head, forming an arch with the tips touching each other; the metopidium, in lateral view, is almost vertical above head. A key, including images of all species (except O. mirandai Fonseca) are also provided. |

| We describe the external morphology of the tadpole of Proceratophrys izecksohni Dias, Amaro, Carvalho-e-Silva & Rodrigues, 2013, its internal oral features, and chondrocranial anatomy, based on specimens collected at the type locality. The tadpole has short and oval body, spiracle with inner wall fused to the body, and oral formula 2/3(1). The oral cavity of P. izecksohni is typical of stream-dwelling tadpoles, with several papillae and pustulations. The chondrocranium is longer than wide and the suprarostral corpora are free ventromedially. The palatoquadrate has a well developed processus pseudopterygoideus. We also compare the tadpole of P. izecksohni with tadpoles those of other species of the genus, emphasizing the usage of larval morphology... |

| This present study re-describes the megalopa stage and provides detailed morphological descriptions and main growth changes observed in stages I through VII of the juvenile instars of the dark shore crab Pachygrapsus gracilis (Saussure, 1858), from the Amazon region. The specimens in this study were reared in the laboratory and the megalopae were collected at Ajuruteua beach in northeastern Pará, Brazil. Previous studies had described the megalopa of P. gracilis from Mexican waters, as well as those of Pachygrapsus transversus (Gibbes, 1850) and Pachygrapsus marmoratus (Fabricius, 1787). A comparison between the Mexican and Amazonian populations of P. gracilis revealed significant morphological differences. The main difference is the presence of 3... |

| The adult stages of Nanomis Lugo-Ortiz & McCafferty and Spiritiops Lugo-Ortiz & McCafferty are described for the first time based on reared material from Argentina and Brazil, respectively. They can be differentiated from the other adults of Baetidae by the following characters: Nanomis, hind wings with three longitudinal veins, second vein bifurcate; costal projection of the hind wings pointed, placed in the basal third of anterior margin; and forceps threesegmented, third segment rounded. Spiritiops, fore wings with paired and long marginal intercalary veins; hind wings with three complete longitudinal veins, and an incomplete small longitudinal vein; costal projection of hind wings pointed, broad at base and placed in the basal third of... |

| The genus Hypheodana Metcalf, 1952, previously considered of uncertain position, is classified in Darninae-Darnini. The following species are treated, together with a re-characterization of the genus: Hypheodana ursus (Fairmaire, 1846), H. cuneata (Fowler, 1894) comb. nov. (formerly in Aspona), H. intermedia (Fowler, 1894) comb. nov. (formerly in Aspona), and also H. proxima sp. nov. (from Costa Rica), H. costata sp. nov. and H. acuta sp. nov.
