Acarology 



Pseudoparasitidae Vitzthum, 1941 



Figure 56 



Diagnosis: Pseudoparasitids have much in common with the preced- 

 ing two famihes but they may be recognized by the reduction of the 

 pretarsus and caruncle of leg i and the modification of the claws of 

 this appendage. The epigynial plate is not triangular. It may or may 



not be fused with the ventral 

 plate. The dorsal plate is entire al- 

 though there may be a suggestion 

 of a horizontal suture present. 

 The specialized seta on the palpal 

 tarsus has three tines.

 Tragardh, 1936. Tarsus i of female 

 showing modified claws and caruncle 

 and ventral plates of female. The claws 

 of leg I of the male are not modified.
