| Nassarius levis sp. nov. is described from Canopus Bank, off Ceará, Northeast Brazil, based on shell morphology. It differs from other Brazilian species of the genus in having a more elongate shell, with a weakly developed parietal shield and a notably smooth surface. This last trait has not yet been described among the Western Atlantic Nassarius, but it is common to other congeners from the Eastern Atlantic, such as Nassarius elatus (Gould, 1845) and the Indo-Pacific, such as Nassarius excellens (Kuroda & Habe, 1961). |

| Potamotrygon tatianae sp. nov., is described from Río Madre de Díos, Peru, upper Rio Madeira basin. The new species is distinguished from all congeners by a unique combination of characters, including its dorsal color pattern formed by a relatively slender, highly convoluted, beige to dark brown vermicular pattern, a single row of dorsal tail spines, and a relatively longer tail posterior to caudal stings. Potamotrygon tatianae sp. nov., occurs sympatrically with other species of Potamotrygon (P. falkneri, P. orbignyi and P. motoro). From the similar species P. falkneri, P. tatianae sp. nov., is further distinguished by the absence of circular, reniform, and oval spots, by its proportionally much longer tail, by having dorsal tail spines in one irregular... |

| Abstract The new species Oiovelia shepardi is described based on macropterous specimens from the departments of La Guajira and Antioquia in northwestern Colombia, and is compared to its presumed closest relative. The female of Paravelia cunhai Rodrigues & Moreira, 2016 and the male of P.polhemusi Rodrigues, Moreira, Nieser, Chen & Melo, 2014 are described for the first time. The specimens of the two species of Paravelia Breddin were collected in waters inside caves in the State of Pará, northern Brazil. Further, the micropterous form of Steinovelia vinnula (Drake, 1951) is described, compared with S.virgata (White, 1879), and new distributional records are provided. Illustrations and a geographic distribution map of all species treated here are... |

| Abstract Ophryotrocha is the most speciose genus within Dorvilleidae, with species occurring in a great variety of environments around the globe. In Brazil, records of Ophryotrocha are scarce and no specific identification is provided for any of the records. Herein we describe a new species of Dorvilleidae, Ophryotrocha zitae sp. nov. Adult and larval specimens were found in the axis of a fragment of the cold-water coral Lophelia pertusa, sampled off São Paulo’s coast, at a depth of 245 m. Both forms are described and illustrated. This new species resembles O. puerilis, O. adherens and O. eutrophila, but can be distinguished based on differences in its mandible and on chaetae shape and arrangement. |

| A new species of Pacholenus Schoenherr from southeastern Brazil (Coleoptera, Curculionidae, Molytinae), and new occurrences of species of the genus. Pacholenus monteiroi sp. nov. (type-locality Brazil, Rio de Janeiro state, Carapebus, Parque Nacional da Restinga de Jurubatiba) is described and illustrated. The weevil develops as a stem gall-former in Calyptranthes brasiliensis Spreng (Myrtaceae). The new species is easily distinguished from the other five known of the genus by the presence of a prominent supra-ocular ridge. An updated key for identification for all species of Pacholenus is provided. Three species of Pacholenus are presently recorded for the states of Rio de Janeiro and São Paulo; P. pelliceus and P. monteiroi occur in both states, while P.... |

| Rhigonema nesoboli sp. nov. (Nematoda: Rhigonematidae) is described from the gut of Nesobolus piedra (Diplopoda: Rhinocricidae) from Eastern Cuba. The new species is characterized by: the body length of both sexes; the cephalic collar umbelliform; the microtricha large, fine, backwardly directed, extending until the first portion of the intestine; the tail comparatively long and subulate in the female and elbowed in the male; the genital tract of Type 4; a number of 19-21 copulatory papillae arranged as 6-7 pre-cloacal pairs with a single median adanal papillae and three post-cloacal pairs; and the spicules arcuate and comparatively slender. It is closer to R. villosum Hunt, 1995, but differs by having a shorter body in both sexes and less copulatory... |

| A new species of the genus Rhinella is described from Canavieiras, southern State of Bahia, in the Atlantic Rain Forest of Eastern Brazil. Rhinella hoogmoedi sp. nov. is characterized by the medium size for the genus (SVL 39.4-52.1 mm in males), snout rounded in dorsal view, with a vertical apical ridge which gives a nearly mucronate aspect, and nearly acute in profile, antorbital and supra-orbital crests developed, parietal crest poorly developed, post-orbital crest large, forming a small lateral ledge, tympanum evident, vertebral apophyses not salient on dorsum, presence of a dorsolateral line of pointed tubercles on the external border of the parotoid gland, continuing along the lateral side of body to the groin, a rounded tubercle at the posterior... |

| A new species of Trichopeltarion A. Milne-Edwards, 1880, is described from off coast of Brazil, namely Trichopeltarion pezzutoi n. sp. The new species is compared to its Atlantic congeners, Trichopeltarion nobile A. Milne-Edwards, 1880, and Trichopeltarion intesi (Crosnier, 1981). The record of T. nobile from Brazil should actually be attributed to T. pezzutoi n. sp. The differences between the genera Trichopeltarion and Peltarion Jacquinot, 1847 are discussed. |

| ABSTRACT Xylocopa bella sp. nov., the second known species of the subgenus Xylocopa (Nanoxylocopa) Hurd & Moure, is newly described from the Espinhaço mountain range, in the state of Minas Gerais, and the Chapada Diamantina, in the state of Bahia, in eastern Brazil. It differs from X. ciliata Burmeister, the type species of X. (Nanoxylocopa), mainly by the possession, by females, of pale hairs intermixed with the black pubescence on the head and metasoma, the more abundant pubescence on mesoscutum and the much denser tergal pilosity, and the possession, by the male, of weakly infumated wing membrane, entirely dark scape, a patch of finely plumose pubescence on the anterior corners of the mesoscutum, narrower face, and shorter distance between the... |

| A new species of the previously monotypic catfish genus Phreatobius is described from an artificial well in the village of Rio Pardo, located 90 km south of the city of Porto Velho, State of Rondônia, Brazil, in the drainage area of the Rio Branco (Rio Madeira system, Amazon basin). Phreatobius dracunculus n. sp. differs from its only congener, P. cisternarum, by the absence of eyes (vs. present), the lack of dark integumentary pigmentation (vs. faint dark pigment always present), the presence of five pectoral-fin rays (vs. four), ventral procurrent rays 11-13 (vs. 22 to 26), dorsal procurrent rays 29-31 (vs. 42 to 50), fewer vertebrae (52 or 53 vs. 59 to 64) and the larger pseudotympanus. The new species shows all diagnostic characters so far proposed for... |

| Abstract We studied 18 cerambycid beetle species native to South America. Seventeen represent new state records in Brazil. Particularly, Chlorethe scabrosaZajciw, 1963 is newly reported for the state of Rio de Janeiro with exclusion of C. brachypteraZajciw, 1963. The Brazilian state of the type locality of Dufauxia guaicurana Lane, 1955 is fixed. Pirangoclytus mendosus (Galileo & Martins, 1996) is synonymized with P. mniszechii (Chevrolat, 1862), and its holotype is a female. Variation on Trypanidius maculatus Monné & Delfino, 1980 is commented. New country and department records for Paraguay are also provided. |
