Figure 268 Oulenzia arboricola 

 (Oudemans). Dorsum of female. Note 

 eyes on lateral margins of propodo- 

 soma. 



Diagnosis: The oulenziids have 

 a propodosomal shield which is 

 not strongly sclerotized as in some 

 groups. Their skin is wrinkled. On 

 the rear of the propodcsoma lies 

 a transverse row of four setae, 

 the inner pair being much shorter 

 than the outer. In place of the 

 cervical seta on each side of pro- 

 podosoma is a lenshke eye. A 

 pair of vertical setae are present. 

 The female genital opening is sit- 

 uated between coxae in and iv. 

 All tarsi are slender, with stalked 

 claws and caruncles and with 

 minute spines. Males are not 

 known. 



Genus: 



Oulenzia Radford, 1950 (= Lenzia Oudemans, 1928, nom. praeocc.) 

 Type. Lenzia arboricola Oudemans, 1928 



Discussion: This mite, the only known species, was found on leaves 

 of Hevea in Sumatra; specimens were also collected on jute in India. 

 Like Czenspinskia it is probably a vegetable feeder.
