N. A. Smith 2011Diff ers from Miomancalla wetmorei in the following characteristics:
ventral margin of ventral tubercle more deeply grooved; transverse ligament furrow deeper, with lateral lip extended farther medially; capital groove wider,
and fl atter; dorsa l supracondylar process less dorsally projected; groove between dorsal
supracondylar process and dorsal condyle wider; ventral supracondylar tubercle
more prominent; tubercle present proximal to dorsal condyle as in Mancalla cedrosensis
(155:1); humerus ~20% longer (Table 2; Livezey 1988, Fig. 3A).
