“…Por tanto, tomando una postura conservadora, sostenemos que se tratan de especie de menor porte, claramente diferenciables de Lama guanicoe y Hemiauchenia, quedando abierta su asignación taxonómica específica según avancen los estudios moleculares, entre otros posibles. Para los especímenes de mayor tamaño, Hemiauchenia, las determinaciones taxonómicas son estudiadas a partir de la anatomía comparada y la osteometría (Scherer et al, 2007;Labarca Encina et al, 2013;Scherer, 2013). Los especímenes arqueológicos finipleistocénicos aquí estudiados como CT970 y CT2529 (Figuras 5 y 6), a primera vista aparecen asociados con los de gran porte, sin embargo no pudimos agruparlos a los comparativos de Hemiauchenia, y aunque los identificamos como Lama guanicoe, también se manifestaron en discordancia con los comparativos de esa especie.…”

“…Por su parte, el representante Lamini de mayor tamaño, Hemiauchenia, también ha sido objeto de debate taxonómico, pero Webb (1974) (Ameghino, 1880(Ameghino, -1881Marshall et al, 1984;Menegaz, 2000;Ubilla, 2004;Scherer et al, 2007;Scherer, 2009;Scherer, 2013;Labarca Encina et al, 2013).…”

“…Los camélidos lamiformes (Webb, 1965) sudamericanos fueron clasificados de distintas formas por diversos autores, conforme avanzó el conocimiento sobre los mismos (Ameghino, 1889;López-Aranguren, 1930;Cabrera, 1932;Wheeler, 1982;Menégaz, 1984;Prado et al, 1987;entre otros), siendo los aportes más recientes y destacados los de , Scherer (2007), Weinstock et al (2009), Labarca & Prieto (2009, Labarca et al (2013), Metcalf et al (2016), Gasparini et al (2017), entre otros. Recientemente, quizás unas de las hipótesis más aceptadas propone que el género Hemiauchenia ha sido el ancestro de Lama y Vicugna (Scherer, 2013), únicos géneros sobrevivientes de la tribu Lamini en la actualidad (Wheeler, 1995). Esta tribu presenta gran similitud morfológica, quedando inicialmente como alternativa para su identificación la variable tamaño corporal (Menegaz et al, 1989).…”

The camelids of Cueva Tunel (Santa Cruz): from the osteometry, towards a differentiation of species. We present a multivariate osteometric analysis on the first camelid phalanges from the archaeological site Cueva Túnel (10,500 years 14 C BP), Central Plateau of Santa Cruz Province, Argentina. We discriminate between fore and hind phalanges. We classify the elements taxonomically by means of Conglomerate and Principal Component analyses. The results show a wide metric variability of the elements assigned to the family Camelidae. We confirm the presence of three camelid morphotypes in a limited temporal range (10,500/10,000 years 14 C BP) during the Pleistocene-Holocene transition. We hypothesize that these types correspond to Lama guanicoe, a larger species such as Hemiauchenia paradoxa, and at least one smaller taxa such as Lama gracilis or Vicugna vicugna. Importantly, all these species would have shared the same ecological niche. This work provides the first morphometric assessment conducted upon extinct camelids from this Patagonian region.

“…The most mesial portion of the crown is broken and the presence of the proto-and parastylid ("llama buttress") cannot be evaluated (Figure 27a). South American camelids are thought to belong to the clade Lamini (Scherer, 2013), and the presence of a "llama buttress" has been proposed as a synapomorphy of the clade (Harrison, 1985;Webb and Meachen, 2004). However, Scherer (2013) noticed that the development of proto-and parastylid is highly variable in South American camelids.…”

Emphasis upon publication as a means of "diffusing knowledge" was expressed by the first Secretary of the Smithsonian. In his formal plan for the Institution, Joseph Henry outlined a program that included the following statement: "It is proposed to publish a series of reports, giving an account of the new discoveries in science, and of the changes made from year to year in all branches of knowledge." This theme of basic research has been adhered to through the years in thousands of titles issued in series publications under the Smithsonian imprint, commencing with Smithsonian Contributions to Knowledge in 1848 and continuing with the following active series: Smithsonian Contributions to Anthropology Smithsonian Contributions to Botany Smithsonian Contributions to History and Technology Smithsonian Contributions to the Marine Sciences Smithsonian Contributions to Museum Conservation Smithsonian Contributions to Paleobiology Smithsonian Contributions to Zoology In these series, the Smithsonian Institution Scholarly Press (SISP) publishes small papers and full-scale monographs that report on research and collections of the Institution's museums and research centers. The Smithsonian Contributions Series are distributed via exchange mailing lists to libraries, universities, and similar institutions throughout the world. Manuscripts intended for publication in the Contributions Series undergo substantive peer review and evaluation by SISP's Editorial Board, as well as evaluation by SISP for compliance with manuscript preparation guidelines (available at https://scholarlypress.si.edu).

Camelids have been known in South America since the late Pliocene, where they arrived from North America as part of the Great American Biotic Interchange (GABI). They became extinct in North America by the late Pleistocene, while surviving in the Southern Cone of South America and in high altitudes of the Andean region. Extinct South American camelids are generally included in the genera Palaeolama and Hemiauchenia, members of which are larger than modern species. We describe here a new, small species of the genus Hemiauchenia based on late Pleistocene specimens previously assigned to Lama guanicoe. This specimen lived in northeastern Brazil at 22 345–21 907 cal a bp, and had a diet composed mainly of C3 plants.
