A New Species

AbstractThe South American spiny-backed treefrog, Osteocephalus leprieurii, as previously understood, is a composite of several species. We redescribe it morphologically on the basis of specimens from French Guiana and add other data on the biology of the species. We describe O. mutabor n. sp., previously confused with O. leprieurii, from the Amazon Basin of Ecuador. The two species differ in coloration, vocalizations and ontogenetic colour change. Osteocephalus leprieurii is remarkable for bearing nuptial excrescences not only on the thumb, but also under the fingers and on the chin. The vocal sac is semicircular expanding posterolaterally. Osteocephalus mutabor n. sp. is characterized by numerous dark transversal bars on the dorsum and a semicircular vocal sac. The amount of keratinized tips on the dorsal granules in males of both species is dependent on sexual activity. Bajo el nombre de la rana arborícola de espalda espinosa Osteocephalus leprieurii, de Sur America, como se ha entendido anteriormente, se confundieron diferentes especies. Se describe de nuevo la especie morfológicamente en base a especimenes de la Guayana Francesa y se añaden otros datos sobre su biología. Describimos O. mutabor n. sp. de la Cuenca Amazónica Ecuatoriana. Ambas especies se diferencian en coloración, vocalizaciones y cambio ontogenético de color. Osteocephalus leprieurii se caracteriza por poseer excrecencias nupciales no solo en el pulgar, sino también bajo los dedos y la barbilla. El saco vocal es semicircular con expansión posterolateral. Osteocephalus mutabor n. sp. se caracteriza por tener rayas oscuras transversales en el dorso y un saco vocal semicircular. La cantidad de puntas queratinizadas en los gránulos dorsales de los machos de ambas especies depende de la actividad sexual.

A New Species

The northernmost Peruvian Andes, a unique biogeographic region characterized by the confluence of multiple distinct ecosystems (i.e. Amazon basin, Pacific rainforest, the Sechura Desert, the northern and central Andes), is the southernmost geographic range limit of the South American shrews representing the genus Cryptotis. In the northernmost Peruvian Andes, two poorly known species have traditionally been reported (C. peruviensis and C. equatoris). Our study, based on molecular and morphologic traits, confirms the presence of C. peruviensis but also the occurrence of C. montivaga, based on specimens erroneously assigned to C. equatoris. Moreover, a new species of Cryptotis from the páramo and montane forests of the Tabaconas Namballe National Sanctuary near the Ecuadorian border is also described. It is a member of the thomasi group and is distinguished from other South American shrews by a unique set of morphological characters, including large body size, comparatively short tail, simple ectoloph of M3, and large PM4 post protocrista.

A New Species

A taxonomic revision of the South American genus Amburana comprised of three species is presented, including the new species A. erythrosperma which is described and illustrated. Amburana cearensis occurs widely in Argentina, Bolivia, Brazil and Paraguay.  Amburana acreana occurs in the Bolivian, Brazilian and Peruvian Amazon. Amburana erythrosperma is endemic to the southern Chapada Diamantina, Bahia, Brazil. The species are distinguished by the color of the stem, the number per leaf and shape of leaflets, the size of inflorescence, color and size of the standard petal, fruit with endocarp developed to form a papery wing surrounding the seed or this lacking, and color of seed. A key to the species is provided together with descriptions, taxonomic comments, geographical distribution maps and illustrations for each.  Lectotypes for A. acreana and A. cearensis are designated.

A new species of small auchenipterid catfish is described based on a single specimen from the Amazon basin and is placed into a new genus. Spinipterus, new genus, is diagnosed by the following striking autapomorphic features: pectoral and dorsal-fin spines with four prominent rows of serrations; lateral margin of the skull roofing bones ornamented with a single row of spines; size reduction of hipurals; elongation and angle of posterior cleithral process; and adducted dorsal fin rests into a mid-dorsal groove. The new genus also differs from most other auchenipterid genera by having lower counts for some fin rays. Current diagnoses of auchenipterid genera do not allow us to place the new species into any genus, which requires us to propose the new genus Spinipterus.

A New Species

AbstractA new nematode species Dichelyne (Cucullanellus) sciaenidicola sp. nov. is described based on specimens collected from the Whitemouth croaker Micropogonias furnieri (Desmarest) and the Argentine croaker Umbrina canosai Berg, from coastal waters of Argentina and Brazil. These nematodes were firstly identified as D. (C.) elongatus (Törnquist, 1931), a commonly reported species from M. furnieri in South American Atlantic waters. However, other species of Dichelyne have so far been reported from this host in the same area, namely D. (C.) rodriguesi (Pinto, Fábio et Noronha, 1970), D. (C.) amaruincai (Freitas, Vicente et Ibañez, 1969) and D. (Dichelyne) micropogonii Pereira et Costa, 1996. A careful re-examination of these parasites, as well as of type specimens of all species reported from M. furnieri, revealed that these nematodes represented a new species. The new species is distinguished from most of its congeners by having papillae 5–7 and 9 forming a subventral line close to cloaca, this feature is shared with other 6 species [D. (C.) dichelyneformis (Szidat, 1950), D. (C.) fraseri (Baylis, 1929), D. (C.) abbreviatus (Rudolphi, 1819), D. (C.) adriaticus (Törnquist, 1931), D. (C.) minutus (Rudolphi, 1819) and D. (C.) mariajuliae Alarcos, Timi, Etchegoin et Sardella, 2006)], which are readily distinguished by their body size, spicules length, distribution patterns of other papillae and position of the excretory pore and deirids. Also, D. (C.) elongatus from Umbrina canariensis (Valenciennes) from West Africa is established as a new species Dichelyne (Cucullanellus) yvonnecampanae sp. nov.; D. (C.) amaruincai from Pacific waters is considered as a valid species, D. (D.) micropogonii is regarded as species inquirendae and D. (C.) rodriguesi is identified as Cucullanus sp.

The Atlantic Forest is the second largest South American tropical-subtropical rainforest and one of the most diverse ecosystems on earth. Hemimycena longipleurocystidiata, a fungal species collected in the Argentinean Atlantic forest, is proposed as new. It is characterized by its whitish and large basidiomata with large pleuro- and cheilocystidia. The species is here described and illustrated and a key is provided to the Hemimycena species known from Argentina.

A New Species

The name Salicornia cuscoensis given to a plant from high Andean saltmarshes near Cusco [Cuzco] and Ayacucho, Peru (South America) is validated by a diagnosis and description. The main morphological characters that separate S. cuscoensis from other closely related species are creeping habit, delicate branches, inflorescence of short and thin spikes, and seed indumentum. The new species clearly differs from other perennial Salicornia taxa growing in high Andean saltmarshes such as S. pulvinata and S. andina. The former forms small compact cushions producing very short, few-flowered inflorescences. The latter shows woody stems and forms larger rounded carpets. Morphologically, S. cuscoensis is also similar to S. magellanica, a species growing along the seashore in southern Patagonia and Tierra del Fuego, but the latter has shorter and wider inflorescences and larger seeds with a different type and arrangement of indumentum. Molecular analyses also supported the separation of S. cuscoensis. Data on habitat, distribution and phylogenetic relationships are presented for the new species and its relatives, and an identification key is given for the South American taxa of the genus Salicornia.
