Aegypiinae

The Aegypiinae share states with the Gypaetinae for characters (3), (4), (5) and (13). The Aegypiinae differ in the following characters: (2) the tuberculum supracondylare dorsale does not project cranially in aegypiines; (11) the fossa m. brachialis is shallower than in Cryptogyps lacertosus in all species except those in Gyps and Aegypius ; (15) only the origins for the distal m. pronator superficialis and profundus are distinct in Necrosyrtes monachus , while in all other taxa, the origin for the m. extensor metacarpi ulnaris is also distinct. The cranial-most attachment point is deeper than the caudal-most attachment, which latter is almost flat in A. monachus , G. fulvus and G. coprotheres , and the third insertion scar present in the aforementioned taxa is shallow; (17) the distal margin between the condyles forms a shallow, broad notch in the species of Gyps and N. monachus and is narrow and deep in A. monachus ; (18) the distal margin of the condylus ventralis is not continuous with the entepicondyle in any species, except N. monachus (continuous).
