Acarology 



The legs are well developed, and all tarsi have pretarsi, caruncles, and 

 claws. The dorsal plate is restricted to the propodosoma or has two or 

 three plates or is absent. The setae are short on the body and append- 

 ages. Stigmata are present with or without short dorsal peritremes. 

 Chelicerae generally have small to rudimentary shears. The tritoster- 

 num is absent.
