Figures 336-338 



Diagnosis: Apterogasterina. Their chelic- 



erae are normal as is the dorsal plate 



which does not curve ventrally. Legs iii 



and IV are placed on or near the edge of 



the body. Usually these are large mites 



with legs which are longer than their body; smaller species have legs in 



which the shape of the segments gives a beaded effect. Sometimes they 



carry cast skins of immature stages on the dorsum.
