And each of the setae is covered in even tinier bristles called spatulae.

这些刚毛被更小的多叫做匙突(spatulae)的结。

Thus, with the avicularia of several species of Lepralia, the movable mandible is so much produced and is so like a bristle that the presence of the upper or fixed beak alone serves to determine its avicularian nature.

因此，对 Lepralia 的几种物种的鸟， 动的下颌产生得如此多， 并且非常像刚毛， 以至仅存在上喙或固定喙就以确定其鸟性质。
