Mesostigmata 



111 



the group and the genus Discourella Berlese, 1910 is considered the 

 type of the family. The family is clearly intermediate between the Uro- 

 podina and Trachytina. Specimens of the family have been found in 

 Canada, Austria, and Java. The family is probably universally dis- 

 tributed. Its habits are similar to other members of the Uropodina. 

 Discourellids are of no known economic or medical importance.

Diagnosis: The tritostemum is covered by the first pair of coxae. 

 Grooves for the legs are flat. The genital and anal openings are each 

 surrounded by a discrete plate. The dorsal plate extends laterally and 

 ventrally so that it covers all but the central portion of the ventral 

 surface.
