chUiditun, iu most Pallenidae, in nearly all Nymph onidae. Their 

 presence or absence is often used as a generic character, helping 

 to separate, e.g., Pallene from Pseii(l<>j//lnie and J'tit/f tmesis, 

 and Phoxichilidium from Anoplodactylus ; nevertheless they may 

 often be detected in a rudimentary state when apparently absent. 

 The legs are smooth or hirsute as the body may happen
