(2) The anterodistal seta of the A2, which is a slender seta in other genera, is a large claw (1Q, 5F, 6AB, 8AB, 13D, 15E, 16F, 18F). In adults of most species, this claw is almost as long and thick as the main distal claw, resembling a scissors blade. This claw emerges only at the last (pre-adult) molt, and it is represented in instars by a fusiform anlage (
