Plate 9, Figxjees 50-54 



Female. — ^Medium to large mite with rather thin palpi and medium- 

 sized rostrum. Palpal femur only slightly swollen externally, about 

 one-third longer than wide, dorsal seta rodlike, serrate, lateral ventral 

 seta same; genual seta rodlike, serrate, on posterior margin of seg- 

 ment; palpal tibial setae simple; single tooth or claw on basal half 

 near center; outer comb about one-third longer than inner, outer with 

 about 23 teeth and inner comb with 26-28 teeth. Kostrum with shield 

 as figured; peritreme simple, composed of small segments. Single 

 pair eyes. Dorsal body setae long, rodlike, serrate, propodosomal 

 setae 133-150/x long and posterior abdominal setae 150/t long. Propo- 

 dosomal and hysterosomal shields large, covering entire dorsum of 

 mite, coarsely striated; two pairs of dorsal submedian and four pairs 

 of marginal setae, three pairs near eye and one pair in posterior corner ; 

 very long shoulder seta; hysterosoma with six pairs of marginal 

 setae and three pairs of dorsal submedian setae. Legs I and IV long; 

 about 400/A long, and IV about 413/a long. Tarsus I with sensory 

 seta about twice as long as the simple guard seta, sensory seta about 

 one-third as long as tarsus ; tibia I with usual short sensory seta and 

 four long serrate setae. Length of body 366/t, including rostrum 

 520/x; width 280/x. 



Type host. — Pandanus tectorius. 



Type locality. — Bataan, Philippine Islands. 



Ty^e.— U.S.N.M. No. 1763. 



The type and one female paratype were collected July 26, 1920, by 

 H. L. Sanf ord ; a second slide with additional specimens has the same 

 data. 



Palpi and tarsi are distinctive. 



The anal-genital region of this mite indicates it to be a female, 

 although the dorsal and the marginal setae are rodlike instead of the 

 staghorn type that normally occurs in females.
