description: Cryptogyps lacertosus (de Vis, 1905) comb. nov.
Lectotype: QM F5507, distal R humerus (designated by van Tets, 1974, p. 58).
Type locality: Kalamurina, Warburton River, Kati Thanda –Lake Eyre Basin, SA. Collected by John W. Gregory in April 1902 (de Vis 1905).
Stratigraphy and Geological age: Katipiri Formation; mid- to late Pleistocene; the fossils are assumed to have derived from fluvial sediments that outcrop in the banks of the river at this point. The associated fauna comprises the Kalamurina Fauna and is typical of the late Pleistocene (Tedford & Wells 1990; Tedford et al. 1992).
Measurements (mm) of QM F.5507: preserved distal width 35.5, lateromedial width of the condylus dorsalis 9.1, depth of the condylus dorsalis 22.3, proximodistal length of the condylus dorsalis 12.3, width of the condylus ventralis 14.1.
Amended diagnosis: As for genus.
Description: In addition to the diagnostic characters described above, the following characters serve to distinguish the species: (8) the palmar attachment for the m. extensor metacarpi radialis (Figure 1A, C; PEMR) on the cranial facies immediately ventral of the tuberculum supracondylare dorsale (Figure 1A; TSD), is shallow, roughly oval-shaped, and orientated dorsoventrally; (9) the sulcus for the dorsal attachment of the m. extensor metacarpi radialis (Figure 1A, B; DEMR) is large and deep on the dorsal facies of the tuberculum supracondylare dorsale, and is directed dorsoproximally; (10) the epicondylus dorsalis is dorsally flat and does not project dorsally of the condylus dorsalis; (11) the fossa m. brachialis (Figure 1A; FB) is deep, with the distal margin positioned well proximal to the tuberculum supracondylare ventrale; (12) the dorsal margin of the fossa m. brachialis extends close to (~ 2 mm) the dorsal margin of the shaft; (13) the tuberculum supracondylare ventrale (Figure 1A; TSV) is not inflated ventrally and is moderately projected cranially; (14) the interior margin of the tuberculum supracondylare ventrale is aligned roughly parallel to the adjacent medial surface; (15) the attachment scars for the origin of the distal head of m. pronator superficialis and of m. pronator profundus are deep, with that for the former being deepest; (16) the incisura intercondylaris (Figure 1A; II) is relatively broad, roughly 3 mm in width, and distinctly separates the two condyles cranially; (17) the distal point of the condylus dorsalis (Figure 1A; CD) is set well proximal of the distalmost point of the condylus ventralis, with the distal margin forming a broad, shallow notch between the two condyles; (18) the distoventral margin of the condylus ventralis (Figure 1A; CV) is continuous with the entepicondyle; (19) and the sulcus scapulotricipitalis (Figure 1D; SST) is shallow and relatively broad.
