A new genus and species of sloth ( Eionaletherium tanycnemius gen. et sp. nov.) recently collected from the Late Miocene Urumaco Formation, Venezuela (northern South America) is herein described based on a partial skeleton including associated femora and tibiae. In order to make a preliminary analysis of the phylogenetic affinities of this new sloth we performed a discriminate analysis based on several characters of the femur and tibia of selected Mylodontoidea and Megatherioidea sloths. The consensus tree produced indicates that the new sloth, E. tanycnemius , is a member of the Mylodontoidea. Surprisingly, the new taxon shows some enigmatic features among Neogene mylodontoid sloths, e.g. femur with a robust lesser trochanter that projects medially and the straight distinctly elongated tibia. The discovery of E. tanycnemius increases the diversity of sloths present in the Urumaco sequence to ten taxa. This taxon supports previous studies of the sloth assemblage from the Urumaco sequence as it further indicates that there are several sloth lineages present that are unknown from the better sampled areas of southern South America.

Selamorpha variegata gen. et sp. nov. is described from Coquimbo Region, Chile. It is characterized by the body dorsally saddle-shaped, brachypterous, tegmina with moderate reticulation, metope elongate, and terga caudally elevated. The new taxon is the second genus of Elicini in Chile and the third of South America. It was found associated with Calceolaria polifolia Hook. (Calceolariaceae).

A new genus and species of Euryrhynchidae is described from Kerala, India. This freshwater shrimp family was previously only known from northern South America and West Africa. Although the inclusion of the genus in Euryrhynchidae is unequivocal (e.g. shape of the accessory ramus of the antennular flagellum, frontal margin of the carapace, telson ornamentation), the presence of a number of unique characters makes the relative placement of the genus within the family unclear, but likely basal to the other genera. The new genus can be easily distinguished from all others within the family by these characters, e.g. the upper antennular flagellum and its accessory ramus being joined over three divisions, the presence of a reduced carpo-propodal brush and a well-developed branchiostegal groove.

AbstractWe report the oldest fossil condor (Vulturidae) from South America and the first from the Pisco Formation (14.0–2.0 Ma) of Peru, described herein as Perugyps diazi new genus and species. The Pisco Formation, exposed on the southern coast of Peru, has produced well-preserved and abundant marine and terrestrial vertebrate fossils from the late Miocene/early Pliocene (6.0–4.5 Ma) Montemar and Sacaco Sur localities, from where P. diazi was recovered. The new condor adds to our knowledge on the evolution and biogeographic distribution of New World vultures. The age of this new species supports the hypothesis that condors probably evolved in North America and entered South America by the late Miocene/early Pliocene. We believe it is likely that the first condors to reach South America probably did so via a coastal corridor along the western side of the Andes where they became part of the diverse coastal fauna in southern Peru.Un Nuevo Cóndor (Ciconiiformes, Vulturidae) del Mioceno Tardío-Plioceno Temprano de la Formación Pisco, PerúResumen. Se reporta el cóndor más antiguo de América del Sur y el primero para la Formación Pisco (14–2 Ma), y se describe como Perugyps diazi. De esta formación, situada en la costa sur del Perú, provienen gran cantidad de aves marinas en muy buen estado de conservación, en especial de los niveles Montemar y Sacaco Sur (Mioceno tardío/Plioceno temprano, 6.0–4.5 Ma), justamente de donde procede Perugyps. Este nuevo cóndor añade importante información sobre la evolución y distribución biogeográfica de estas aves, pues su edad apoya la hipótesis de que los cóndores probablemente evolucionaron en América del Norte y entraron a América del Sur entre el Mioceno tardío y el Plioceno temprano. Sugerimos que su llegada pudo realizarse por el corredor costero del lado occidental de los Andes, en donde pasaron a formar parte de la diversa fauna del sur del Perú.

A large ichthyosaur from the Early Tithonian (Late Jurassic) of the Neuquén province, Argentina, represents a new genus and species, Caypullisaurus bonapartei, within the family Ichthyosauridae. The holotype is the most complete skeleton of a mature ichthyosaur known to date from the Jurassic of South America. In comparison with other Late Jurassic ichthyosaurs, the new taxon shares a long and slender rostrum, degenerate dentition in adults, and the enlargement of the orbit with Ophthalmosaurus. Unlike Ophthalmosaurus, the forefin of Caypullisaurus has four major digits composed of tightly packed, polygonal phalanges, and pre- and post-axial accessory digits. Caypullisaurus demonstrates that ichthyosaurs were more diverse during the Late Jurassic than thought previously.

Kotumsaridae, a new family of amphipod crustaceans is described from Kotumsar Cave in the state of Chhattisgarh, India. The family is based on Kotumsaria bastarensis, new genus and species, which is the only known member of the new family recorded to date. Although the new family appears to share some morphological characters with several other taxa from the southern hemisphere considered members of the superfamily Crangonyctoidea, including the New Zealand endemic genus Paracrangonyx, both its taxonomic and phylogenetic affinities remain unclear. Specimens of the new taxon, measuring just over 2 mm in length, were collected from the sediments of a pool in Kotumsar Cave but are believed to have migrated from deeper interstices. Kotumsaria bastarensis is only the third subterranean amphipod recorded to date from the Indian subcontinent.

Abstract. A very distinctive new deep-photic coccolithophore is described from the NE Indian Ocean. The new species is trimorphic with: 200–300 body coccoliths bearing low spines attached by narrow stems to a basal narrow-rimmed placolith structure; up to 18 circum-flagellar coccoliths with tall sail-like spines; and up to 22 coccoliths with moderately elevated spines occurring both around the circum-flagellar coccoliths and antapically. These features make the coccolithophore unique and require placement in a new species and genus. The basal structure, however, shows similarities to a recently recognized group of narrow-rimmed placoliths. Hence, the new coccolithophore provides some support for this grouping as a significant addition to our understanding of coccolithophore biodiversity, and potentially an explanation for a set of anomalous molecular genetic results. In addition the new taxon provides further evidence that the deep-photic coccolithophore community is more diverse than has been assumed.

A fragmentary specimen of pterosaur originally assigned to the genus Pterodaustro Bonaparte, 1970 is reassessed. The presence of a sagittal dorsal cranial crest on a fragment of nasopreorbital arcade with linear vertical trabeculae and the occurrence of alveolar protuberances on the os dentale indicate the new specimen has similarities with crested pterodactyloid pterosaurs of the family Ctenochasmatidae, and with members of the Dsungaripteridae. The presence of alveolar protuberances allows us to assign the specimen to the Dsungaripteridae. It forms the basis of a new genus and species, Domeykodactylus ceciliae.

Xujiahe Formation

A new genus and species of the cockroach family Caloblattinidae, Dazhublattella lini gen. et sp.n., is described from the Upper Triassic Xujiahe Formation of Sichuan Province, in southwestern China. The new taxon is similar to the Triassic Caloblattina mathildae (Geinitz, 1883) (Vršanský & Ansorge 2007) in the venation and pattern, but differs in the less elongated forewing with arched anterior margin. An elemental analysis of the wing is undertaken using Energy Dispersive X-ray analysis.
