Description. - Similar to Attila Lesson, but tarsus longer and beak smaller. Bristles of the gape undeveloped. Beak about as long as the head; its shape is reminiscent of those of Attila and Laniocera Lesson. The outer toe is united to the middle one over a greater distance than in Attila, but not quite to the end of the second phalange. Tarsus pycnaspidean, longer than the culmen and the clawed middle toe, and longer than one-third of the wing length. Tail short and slightly rounded. The fifth and sixth primaries are the longest, the tenth between the second and third. Genotype:- AKLETOS PERUVIANUS, new species" (Dunajewski 1948); "Akletos Dunajewski, 1948, Bull. Brit. Ornith.
