- We describe new remains of Urumaquia robusta CARLINI, BRANDONI & SÄNCHEZ, 2006, which significantly improve the knowledge of the species and allow a more precise discussion about the relationships with the rest of the South American Megatheriinae. The new remains (ulna, phalanx, femora, patella, tibia, astragalus, navicular, metatarsals IV–V) described here suggest close affinities of this taxon with the species of Pyramiodontherium and with Megatheriops rectidens, based on morphological similarities of the ulna (length, gracility), femur (general morphology, shape of the medial margin), and astragalus (angle between the discoidal and odontoid facets). In fact, the shape of femoral medial margin is a shared derived character amongUrumaquia, Pyramiodontherium and Megatheriops. However, and despite the increasing information concerning Tertiary species, their phylogenetic relationships are only partially understood.
Neue Funde von Urumaquia robusta Carlini, Brandoni & Sánchez, 2006 werden vorgestellt, die erheblich zum Verständnis der Art beitragen und eine präzisere Diskussion der Verwandtschaftsverhältnisse zu anderen Vertretern der südamerikanischen Megatheriinae erlauben. Das hierin beschriebene neue Material (Ulna, Phalange, Femura, Patella, Tibia, Astragalus, Navikulare, Metatarsalia IV–V) deutet auf nähere Verwandtschaft zu den Taxa Pyramiodontherium und Megatheriops rectidens hin. Dies wird unterstützt durch morphologische Ähnlichkeit der Ulna (Länge, Grazilität), des Femurs (generelle Morphologie, Form des medialen Randes) und des Astragalus (Winkel zwischen der Diskoidal- und Odontoidfacette). Tatsächlich handelt es sich bei der Ausprägung des medialen Femurrandes um eine Synapomorphie von Urumaquia, Pyramiodontherium und Megatheriops. Allerdings sind die phylogenetischen Verwandtschaftsverhältnisse, trotz Zunahme von Informationen über tertiäre Taxa, bisher nur teilweise verstanden.
