Two new species of Pamphobeteus Pocock1901 (Araneae: Mygalomorphae: Theraphosidae) from Brazil, with a new type of stridulatory organ
. Zootaxa 1826:45-58.
So the differences in stridulatory organs
are not easily explained by interspecific interactions except assuming much wider ranges than today during the ice ages.
Fiddler on the tree--a bush-cricket species with unusual stridulatory organs
An unusual stridulatory organ with the plectrum on trochanter II and the striae on coxa I is found in both sexes of this species.

In single stridulatory organs
, sounds are produced by rubbing the front of the abdomen against the rear of the cephalothorax, the surfaces of which are provided either with ridges, pegs or stiff setae (Figs.
One insect group in which temporal characteristics of generated sounds are influenced by the size of the stridulatory organs
is dung beetles: in this taxon, the pulse durations of defensive sounds increase with the length of the stridulatory structures (Carisio et al.
Theraphosid spiders possess stridulatory organs
