 Lundblad. Venter of female. (After 

 Lundblad 1936) 



Diagnosis: These mites have an 

 armored body and a dorsal su- 

 ture. The maxillary organ usually 

 has a short rostrum and the palpal 

 tibia projects ventrally and distal- 

 ly to form a weak shear with the 

 palpal tarsus. The coxal plates 

 have a tendency to grow together. 

 Usually the genital organ lies in 

 the opening in the ventral armor. 

 As a rule genital pads are covered 

 with setae and many genital suck- 

 ers are present.
