Choloepodini

PP = 98, age = 7.07 Mya (5.67–8.93).

This clade is composed of the genus Pliomorphus; the Antillean megalonychines Megalocnus, Parocnus, Neocnus and Acratocnus; and the living sloth genus Choloepus . It was consistently recovered in our analyses with the arrangement ( Pliomorphus, (( Megalocnus, Parocnus), ( Neocnus, ( Acratocnus, Choloepus)))). In one exception—in par_EW— Neocnus, Acratocnus and Choloepus were recovered in a polytomy.

Choloepodiniwassupportedbyeightsynapomorphies (six for both methods and two exclusively for BI): snout downturned anteroventrally, in lateral view; evenly convex dorsal surface of the skull; minimum width of palate between toothrows equal or less than width of Mf2; absence of postorbital process of zygomatic arch; occiput wider than deep; presence of recessus meatus (BI); presence of a strong concavity between greater trochanter and the head of femur (BI); and patellar trochlea confluent with lateral, but not with medial condylar surface.
