A new genus and two new species of minute leptodactylid frogs from northern South America, with comments upon Phyzelaphryne (Amphibia: Anura: Leptodactylidae) Naturalis
Hoogmoed, M.S.; Lescure, J..
The synonymisation of Phyzelaphryne miriamae Heyer with Eleutherodactylus nigrovittatus Andersson is denied and it is shown that both species are quite distinct in numerous characters. A new genus (Adelophryne) of minute leptodactylid frogs with pointed discs on the toes and a distinctly reduced fourth finger, containing two new species (A. adiastola spec. nov. and A. gutturosa spec. nov.) is described from northern South America. A key to separate the diminutive leptodactylid frogs with pointed toetips is given. The relationships of the new genus are not clear, but possibly are with one of the species groups of Eleutherodactylus, of the subfamily Eleutherodactylinae.

A new genus of Toads (Amphibia: Anura: Bufonidae) from the Pacific Slopes of the Andes in Northern Ecuador and Southern Colombia, with the description of two new species Naturalis
Hoogmoed, M.S..
The genus Andinophryne, characterized by the presence of an omosternum, an externally visible tympanum, elongate parotoids and extensively webbed hands and feet is described from the Pacific versant of the Andes in northwestern Ecuador and southwestern Colombia. Two new species, Andinophryne colomai and A. olallai are described from Ecuador. The recently described Bufo atelopoides Lynch & Ruiz-Carranza is transferred to the new genus. Some comparisons with other atelopodid Bufonidae (Atelopus, Dendrophryniscus, Melanophryniscus, Oreophrynella, Osornophryne, Rhamphophryne) are made and some very tentative remarks on their relationships are ventilated.

A new, Neotropical species of Acanthocyclops (Copepoda: Cyclopoida: Cyclopidae) Naturalis
Reid, Janet W.; Suárez-Morales, Eduardo.
Acanthocyclops smithae, a new species of cyclopoid copepod and a member of the A. vernalis-robustus group, is described from Honduras and southeastern Mexico. The few previous records of species of Acanthocyclops in tropical latitudes apparently refer to isolated populations of a few widespread temperate species. Acanthocyclops smithae is the only known exclusively tropical member of the genus.

A new species and new distribution records of Pickeliana (Opiliones: Laniatores: Stygnidae) Zoologia
Hara,Marcos R.; Pinto-da-Rocha,Ricardo.
A new species of Pickeliana Mello-Leitão, 1932, P. albimaculata sp. nov., is described from Jussari, Bahia, Brazil. It can be easily distinguished from the already described species by the presence of white spots on mesotergal area I and anal opercle. It is similar to P. pickeli Mello-Leitão, 1932 by the presence of a large, ventro-apical pointed tubercle on femora III-IV. A cladistic analysis was performed adding a new character to the available character matrix, the presence of a large and ventro-apical pointed tubercle on male femur IV. According to this analysis, P. albimaculata sp. nov. is sister species of P. pickeli. Additionally, we present an identification key and an update on the geographical distribution of species of this genus in northeastern...

A new species of Buenoa Kirkaldy (Hemiptera, Heteroptera, Notonectidae) from Rio de Janeiro, Brazil Rev. Bras. entomol.
Barbosa,Julianna F.; Ribeiro,José Ricardo I.; Nessimian,Jorge L..
Members of Buenoa are restricted to the Western Hemisphere, with the greatest diversity of species in South America. There are about 50 described species and approximately 20 of them have been reported from Brazil. Buenoa pseudomutabilis Barbosa, Ribeiro and Nessimian, sp. nov. is described here from Maricá, Rio de Janeiro State. This species resembles B. mutabilis Truxal, 1953 because males have a stridulatory area on inner surface of forefemur, forefemur narrowed at apex, with length more than three times its width at apex, and rostral prong longer than third rostral segment. Males of B. pseudomutabilis sp. nov. can be readily recognized by the presence of 21 to 25 teeth in the stridulatory comb of foretibia, whereas in B. mutabilis the stridulatory comb...

A new species of Diaphorocleidus (Monogenea: Ancyrocephalinae) from the gills of Argonectes robertsi (Characiformes) and new records of dactylogyrids parasitic on fishes from the Xingu River, Amazon Basin, Brazil Rev. Bras. Zool.
Moreira,Juliana; Scholz,Tomáš; Luque,José Luis.
ABSTRACT Diaphorocleidus altamirensis sp. nov., parasitic on the gills of Argonectes robertsi Langeani, 1999 from the Xingu River, northern Brazil, is described. The new species differs from its six congeners by the morphology of the male copulatory organ (which comprises a coil of six rings), by the midventral vagina, and by the presence of only one pair of eyespots. It is the first species of Diaphorocleidus Jogunoori, Kritsky & Venkatanarasaiah, 2004 described from hemiodontid fishes. In addition, new host and geographical records of seven species of dactylogyrids found on fish from the Xingu River are reported.

A new species of Glaphyropoma: the first subterranean copionodontine catfish and the first occurrence of opercular odontodes in the subfamily (Siluriformes: Trichomycteridae) Neotropical Ichthyology
Bichuette,Maria Elina; Pinna,Mario César Cardoso de; Trajano,Eleonora.
A new species of the rare copionodontine genus Glaphyropoma is described from subterranean waters in the Diamantina Plateau, Bahia State, central northeastern Brazil. This is the first troglomorphic species in the subfamily Copionodontinae. It is distinguished from all other copionodontines by the presence of opercular odontodes, and further distinguished from its only congener, G. rodriguesi, by the reduction of dark integumentary pigmentation. The new species shares the single synapomorphy previously proposed for Glaphyropoma, the marked narrowing of the first hypobranchial and indirect character evidence also supports its inclusion in the genus. The presence of opercular odontodes in the new species, in combination with a reviewed hypothesis of sister...

Souza,Lesley S. de; Melo,Marcelo R. S.; Chamon,Carine C.; Armbruster,Jonathan W..
Hemiancistrus cerrado is described from the tributaries of rio Araguaia, rio Tocantins basin. Hemiancistrus cerrado has external similarities with H. megalopteryx and H. punctulatus from coastal streams of southern Brazil, and can be distinguished by having a larger internarial width, 15.9-21.1% of head length (vs. 11.2-14.0% in H. megalopteryx and 11.2-13.9% in H. punctulatus) and, with little overlap, by the larger adipose-fin spine length, 9.4-13.6% of standard length (vs. 7.1-8.7% in H. megalopteryx and 7.4-10.0% in H. punctulatus). Hemiancistrus cerrado further differs from H. megalopteryx by having the pectoral-fin spine reaching maximally to the middle of the pelvic-fin spine when adpressed in adult males (vs. reaching tip). Hemiancistrus cerrado...

A new species of Mucrosomia (Collembola: Isotomidae) from Brazil Rev. Bras. Zool.
Mendonça,Maria Cleide de; Queiroz,Gabriel Costa.
A new species of Collembola, Mucrosomia alticola sp. nov., is described and illustrated based on material from "Parque Nacional da Serra dos Órgãos" (State of Rio de Janeiro) and from "Parque Nacional da Serra do Caparaó" (State of Minas Gerais). This is the first record of a species of Mucrosomia for Brazil. The genus has, up to date, only three species and can be diagnosed by the absence of eyes and pigmentation, PAO present, tenent hair pointed, Abd V and VI fused, manubrium with 1+1 chaetae on anterior side, long dens and a remarkable mucro with five teeth. The presence of chaetae on ventral thorax, between segments II-III, supports the new species.

A new species of Serrapinnus Malabarba, 1998 (Characidae: Cheirodontinae) from Rio Grande do Norte State, northeastern Brazil Neotropical Ichthyology
Jerep,Fernando C.; Malabarba,Luiz R..
Serrapinnus potiguar, new species, is described from the rio Ceará-Mirim, a coastal drainage in the Rio Grande do Norte State, northeastern Brazil. The new species is distinguished from the other species of the genus by the shape and arrangement of the ventral procurrent caudal-fin rays of the sexually dimorphic males; where the hypertrophied elements present the shape of a series of scimitars arranged radially, forming a semi-circle on the ventral margin of the caudal peduncle. Furthermore, the new species is diagnosed from S. heterodonand S. piaba, sympatric congeners from the northeastern Brazilian drainages, respectively by the presence of incomplete lateral line and teeth bearing at most five cusps.

A new species of Sipapoantha (Gentianaceae: Helieae) from northern Brazil Naturalis
Lepis, K.B.; Maas, P.J.M.; Struwe, L..
A new species from Gentianaceae (tribe Helieae) is described from northern Brazil. Sipapoantha obtusisepala sp. nov. is distinct from the previously single member of the genus, Sipapoantha ostrina, by having a woody and branched habit, sessile and ovate leaves with an acute apex, and a smaller calyx with circular lobes. Sipapoantha obtusisepala is based on somewhat incomplete material and tentatively placed in Sipapoantha based on the presence of key generic characters such as coriaceous leaves with strongly revolute margins and blue corollas. It has only been recorded from one locality in the Brazilian-Guyana border area in the state of Roraima.
