A gynandromorph of Xylocopa nigrocincta Smith (Hymenoptera: Apidae) Neotropical Entomology
Lucia,Mariano; Abrahamovich,Alberto H; Alvarez,Leopoldo J.
We describe a mixed gynandromorph of Xylocopa (Neoxylocopa) nigrocincta from a single specimen from Argentina. The specimen presents bilateral asymmetry, with the right half of its head displaying male characters and the left half displaying female characters; the mesosoma presents male characters mostly in the right half of the prothorax, pronotal lobe and distal half of the fore tibia and in the pubescence of tarsus; the rest of the mesosoma and the metasoma display female features

A new angiosperm leaf morphotype from the Early Cretaceous (Late Aptian) of San Luis Basin, Argentina Ameghiniana
Puebla,Gabriela G.
A new fossil angiosperm leaf morphotype, "LC-Microphyll trifoliate", from the Late Aptian La Cantera Formation, central western Argentina, is described. The leaf remains occurred at the type section of the formation within a low diversity macrofloral association. Fossils are found mainly as isolated small size leaflets (0.3-1.5 cm long). The leaves are pinnately compound (imparipinnate, trifoliate), the leaflets have pinnately lobed margin, first vein category pinnate, secondary veins craspedodromous opposite to subopposite ending at the apex of lobes and an intramarginal vein. "LC-Microphyll trifoliate" is among the earliest record of leaf remains possibly allied to the eudicots and one of the first evidence of angiosperm with compound leaves.

A new araucarian fossil species from the Paleogene of southern Argentina Ameghiniana
Panti,Carolina; Césari,Silvia N.; Marenssi,Sergio A.; Olivero,Eduardo B..
A new Araucariaceaea from the Paleogene of Tierra del Fuego Province, Argentina is described. Araucaria pararaucana sp. nov. has imbricate, ovate-lanceolate leaves with an acute apex, characterized by the presence of discontinuous and longitudinally oriented stomatal rows separated by epidermal cells, which may be slightly sinuous. Stomatal guard cell surface is granular. These fossil leaves are compared with the extant sections Bunya, Intermedia and Araucaria. Their anatomical characters along with the external morphology suggest a close affinity with the extant southern Patagonian species A. araucana (Molina) K. Koch. The record of this new late Eocene species provides more evidence for a probable unique representation of Section Araucaria in the area...

A new Cretaceous terrestrial ecosystem from Gondwana with the description of a new sauropod dinosaur Anais da ABC (AABC)
Calvo,Jorge O.; Porfiri,Juan D.; González-Riga,Bernardo J.; Kellner,Alexander W.A..
A unique site at the northern area of Patagonia (Neuquén, Argentina) reveals a terrestrial ecosystem preserved in a detail never reported before in a Late Cretaceous deposit. An extraordinary diversity and abundance of fossils was found concentrated in a 0.5 m horizon in the same quarry, including a new titanosaur sauropod, Futalognkosaurus dukei n.gen., n.sp, which is the most complete giant dinosaur known so far. Several plant leaves, showing a predominance of angiosperms over gymnosperms that likely constituted the diet of F. dukei were found too. Other dinosaurs (sauropods, theropods, ornithopods), crocodylomorphs, pterosaurs, and fishes were also discovered, allowing a partial reconstruction of this Gondwanan continental ecosystem.

A new genus and species of Heroini (Perciformes: Cichlidae) from the early Eocene of southern South America Neotropical Ichthyology
Perez,Patricia Alano; Malabarba,Maria Claudia; del Papa,Cecilia.
The Lumbrera Formation is the uppermost unit of the Salta Group, which crops out in northwestern Argentina. The paleoenvironment of the Lumbrera Formation is interpreted as a perennial lake deposited under temperate climatic conditions during the early to middle Eocene. Its fossil content is made up of palynomorphs, insects, crocodiles, turtles, lizards, and mammals, besides an ichthyofauna formed by cichlids, poeciliids and dipnoans. †Plesioheros chauliodus is described based on a single individual from this formation, which was fossilized as a lateral view impression (missing anal and caudal fins). It can be distinguished from other cichlids by a moderately deep body, enlarged anterior dentary teeth bearing subapical cusp, a low abdominal vertebral count...

A new palm trunk from the Upper Cretaceous of Argentina Ameghiniana
Ottone,Eduardo G..
A new morphospecies of palm trunk, Palmoxylon pichaihuensis sp. nov., is proposed on the basis of several specimens recovered from a succession of tuffs and breccias at Pichaihue, Neuquén Province, Argentina. The specimens comprise atactosteles that display densely crowded fibrovascular bundles in the peripheral zone, and less congested fibrovascular bundles, randomly scattered or arranged in irregular circles in the central zone; sclerenchyma reniform; xylem with 1-4 large metaxylem vessels and 6-12 smaller protoxylem elements in the central zone, and an f/v ratio of 1.3-2:1. The Pichaihue fossil assemblage is similar to, and probably coeval with the flora of Bajo de Santa Rosa, Río Negro Province, reflecting a warm and relatively humid climate, at ca....

A new small deinonychosaur (Dinosauria: Theropoda) from the Late Cretaceous of Patagônia, Argentina Anais da ABC (AABC)
Porfiri,Juan D.; Calvo,Jorge O.; Santos,Domenica dos.
Here we report on a new small deinonychosaurian theropod, Pamparaptor micros gen. et sp. nov., from the Late Cretaceous of Patagônia, Argentina. Pamparaptor micros exhibits a pedal structure previously unknown among South Américan deinonychosaurians. The new material provides new evidence about the morphology and taxonomic diversity of Patagônian deinonychosaurs. Pamparaptor is the smaller non-avialae Patagônian deinonychosaur, probably with about 0.50-0.70 meters, long. The pedal construction resembles, that of Troodontid or basal Dromaeosaurids. Nevertheless, up to now, we considered Pamparaptor a peculiar Patagônian Dromaeosaurid with troodontid-like pes.

A new species of Microtetrameres (Nematoda, Tetrameridae) parasitizing Buteogallus urubitinga (Aves, Accipitridae) from northeastern Argentina Anais da ABC (AABC)
DÍAZ,MARIANO Dueñas; DRAGO,FABIANA B.; NÚÑEZ,VERÓNICA.
Abstract A new tetramerid nematode, Microtetrameres urubitinga n. sp., is described from specimens recovered from the proventriculus of the great black-hawk, Buteogallus urubitinga (Aves: Accipitridae), from Formosa Province, Argentina. The males of the new species are characterized by having spicules unequal (length ratio of spicules 1:3.8–5.9) and dissimilar in shape (right spicule with a simple tip, left spicule with a symmetrical bifurcated tip), caudal papillae arranged asymmetrically (two pairs precloacal and two pairs postcloacal) and cloacal lips highly protruded forming a tube. The gravid females are permanently coiled clockwise or counterclockwise in a spiral and having a tail tapering gradually to a sharp point, with a cuticular fold. This is...

A new species of Stilobezzia Kieffer from the neotropical region (Diptera, Ceratopogonidae) Rev. Bras. entomol.
Cazorla,Carla G.; Ronderos,Maria M.; Spinelli,Gustavo R.; Torreias,S.R.S.; Ferreira Keppler,Ruth L..
A new species from the Neotropical Region, Stilobezzia (Stilobezzia) pseudopunctulata Cazorla & Ronderos, is described and illustrated based on male and female adults and pupal exuviae. Adults were collected in the Argentinian provinces of Chaco, Formosa, Corrientes and Buenos Aires, and in Santa Cruz, Bolivia. The pupa was collected from mats of floating aquatic macrophytes in a lagoon in Ilha da Marchantería, in the vicinities of Manaus, Brazil. This new species is compared with its similar congener Stilobezzia punctulata Lane, from which it can be mainly distinguished by the wing with only two dark spots, the parameres longer and hook-shaped, the pupal respiratory organ with 11-12 pores and the very short apicolateral processes of the anal...

A new species of Uncinia (Cyperaceae) from the New World and the first report of U. Chilensis from Argentina Darwiniana
Wheeler,Gerald A..
A new species of Uncinia (Cyperaceae), U. austroamericana, is described and illustrated from austral South America and from the Tristan da Cunha archipelago in the south-Atlantic Ocean. This species grows in persistently wet, base-poor sites, particularly in Sphagnum bogs, and is known from southern Patagonia, Tierra del Fuego, and from the largest island of the Tristan da Cunha group. It differs both morphologically and ecologically from the similar-appearing U. macrolepis, a minerotrophic species best known from moist depressions in grasslands. The new species differs morphologically from U. macrolepis by possessing achenes that, when mature, are pale-colored and conspicuously-thickened at the apex and, also, by having more or less loosely-flowered...

A preliminary revision of knowledge status of felids in Argentina Mastozool. neotrop.
Lucherini,Mauro; Soler,Lucía; Luengos Vidal,Estela.
Argentina is the host of 10 wild felids (28% of the world total). Although the Cat Specialist Group Action Plan has classified the conservation status of Argentine cats as relatively good, the ranking was based on a largely incomplete database for at least 80% of the species. Here we review the current status of knowledge and research effort of Argentine cats, compare it with their distribution, habitat association and conservation status and provide guidelines for their future research. Between 1990 and 2000, cat research has received increasing attention in Argentina. Twenty-four projects have been carried out, but only 13 studies are still in progress. A rank of research priority has been calculated for each felid and ecoregion. Our analysis showed that...
