| A new species of Amphisbaena is described from a semi-deciduous forest in Conceição do Mato Dentro, southern Espinhaço Range, Minas Gerais, Brazil. The following combined characters can diagnose the new species from all congeners: head round-shaped; two or three precloacal pores sequentially arranged; 190-199 body annuli; 2-3 lateral annuli; 23-25 caudal annuli; autotomy sites on caudal annuli 7-9; 12-14 dorsal segments on midbody annulus; 14-16 ventral segments on midbody annulus; three supralabials; three infralabials; postmalar row present or absent; dorsum light brown, with cream intersegmental sutures; venter cream. To date, the new species is known only from the Espinhaço Range, highlighting the importance of conservation actions for these mountains. |

| Rhamdia enfurnada, a new troglobitic (exclusively subterranean) catfish, is described from the Gruna do Enfurnado, Serra do Ramalho, southwestern Bahia State, middle São Francisco River basin. It differs from epigean congeners from the São Francisco River basin by the variable eye size, ranging from reduced to externally invisible (bilateral asymmetry in development of eyes is frequently observed), with a conspicuous orbital concavity (orbital diameter varying from 6.4 to 13.6% of head length in R. enfurnada and from 14.5 to 24.4% in the epigean species); by the dark pigmentation reduced due to a decrease in density of melanophores, and also variable. In comparison to other cave species, R. enfurnada presents a low degree of troglomorphism regarding... |

| ABSTRACT Larvae of many-plumed moths (Alucitidae), especially in the world-wide genus Alucita Linnaeus, 1758 are known as borers or gall-inducers on flowers, fruits and shoots of a few dicotyledonous families, including Bignoniaceae, Caprifoliaceae and Rubiaceae. However, there is no study available on the biology of the monotypic, Neotropical genus Prymnotomis Meyrick, 1931 except for its original description that was based on a single male, the holotype of Prymnotomis crypsicroca Meyrick, 1931 from Espirito Santo, Brazil. We describe here a second species for this genus, Prymnotomis cecidicola sp. nov. whose larvae induce galls on Cordiera elliptica (Cham.) Kuntze (Rubiaceae), a dioecious plant with dimorphic inflorescences found in the Brazilian... |

| A new species of Cephalobium from Gorina, La Plata, Argentina, parasiting nymphs of Anurogryllus muticus (De Geer) (Orthoptera, Gryllidae) is described and illustrated. This nematode can be characterized by having the stoma longer than broad, the glottoid apparatus anisoglottid and anisomorphic, divided into two portions, one with cuticularized walls and the other with three simple dorsal teeth. The male is further characterized by the presence of two long and separated spicules and short gubernaculum without any projection. Genital papillae are arranged in five postanal pairs. |

| A new characid species, Hyphessobrycon hexastichos, is described from the upper rio Tapajós, Mato Grosso, Brazil. The new species is distinguished from all other Hyphessobrycon species by the presence of black zigzag longitudinal lines between longitudinal rows of scales in the lateral of body, maxilla with 3-5 teeth, i,6 pelvic-fin rays, 18-22 branched anal-fin rays, 4 scale rows above and 3 scale rows below of lateral line, lateral line with 9-13 perforated scales, and 33-35 scales in a longitudinal series. |

| The morphology, ontogeny, life-cycles and distribution of species of the Order Proteocephalidea (Cestoda), is discussed. A brief historic of the classifications is presented. The actual scheme of taxonomy of WOODLAND (1924-1935) is criticicized and a new classification for the group is proposed. The phylogenetic uniformity of Proteocephalideans is reestablished with this classification. The genera of Monticelliidae (sensu Woodland) are transferred to the subfamilies Proteocephalinae and Corallobothriinae. Only one family is accepted in the Proteocephalidea. Proteocephalidae La Rue. 1911: with five subfamilies: Proteocephalinae. Corallobothriinae. Sandonelliinae. Gangesiinae and Acanthotaeniinae. |

| ABSTRACT Drosophila monsterae sp. nov. is described from 11 males and 13 females collected from the inside of closed inflorescences of Monstera lentii (Araceae) at 1810 m altitude in the Forest Reserve of Cerro de La Carpintera, Canton La Unión, Province of Cartago, Costa Rica. Although flies have been seen wandering and copulating inside the floral chambers of closed inflorescences during the floral female phase, eggs or larvae have not yet been found either in the spathe or in the fleshy spadix. The new species is related to Drosophila tristani Sturtevant, 1921, from San José, Costa Rica, from which it differs mainly by having smaller slightly circular compound eyes, distinctly broader genae (cheek index ca. 2.4 vs 5 in D. tristani), and the inner... |

| A new species of Hypostomus Lacépède is described from the rio Paraguaçu basin, Bahia State, Brazil. The new species is distinguished from its congeners by having black and conspicuous dots on a pale background, which are similar in size on the head, trunk, and fins, along with ventral surface of head and abdomen naked or the latter plated exclusively on its anterior portion, absence of ridges on head and trunk, and caudal-fin lobes relatively similar in length. The new species further differs from the sympatric H. chrysostiktos by having seven branched dorsal-fin rays instead of 10-11 and represents the eleventh siluriform species endemic to the rio Paraguaçu basin. |
