Lophotriorchis Sharpe, Oat. B.M., i, pp. 226, 255 (1874).
Type, Astur kieneri Geof. St.-Hil.
The genus Lophotriorchis differs from Hieraetus in its more powerful tarsus and longer central toe as well as in having a long crest. From Spizaetus it differs in its longer wing, the primaries exceeding the secondaries by more than the length of the tarsus and also in having a shorter tail. The claws are exceptionally long and well curved, that of the third toe exceeding in length the culmen, not including the cere.
The genus contains two species—one Indo-Malayan, the other South American.
