ability of Mysmenopsis dipluroamigo to survive without the 
“proper” host is shown by the fact that Kirkendall and 1 found a 
complex space web in a bush, resembling the web of the “social” 
spider Anelosimus eximius (Simon, 1892). This web (34 X 37 X 27 
cm) contained 9 females, 10 subadult females, 16 males, 2 subadult 
males and 25 juvenile M. dipluroamigo, in addition to 2 Ischnothele 
guianenesis (Walck.). Other associates of Diplura webs encompass 
Coleoptera, dipteran larvae (Kirkendall, in prep.), lepidopteran 
larvae (Robinson, 1977), and therediid spiders of the genus Argy- 
rodes (Vollrath, 1977).

coxal processes (Cpx) of the pedipalpae with the reduced pedipalp (P), and, finally, 
the chelicerae (Ch) with the cheliceral claws (CC).
