MITES OF FAMILY CHEYLETIDAE — BAKER 289 



CHELETOPHYES HAWAIIENSIS, new species 

 Plate 10, Figxjres 55-59 



Female. — Kostrum and palpi narrow. Palpal femur swollen on 

 outer margin, dorsal seta rodlike, serrate; dorsolateral setae split 

 as figured ; lateral ventral setae rodlike, serrate. There is no dorsal 

 genual seta ; the usual number of femoral setae is 4, but in this case 

 there are 5, the extra one appearing to be the dorsolateral seta; tibial 

 setae simple ; palpal claw long, slender with 9 basal teeth ; inner comb 

 with about 34 teeth, weaker and shorter than outer comb which has 

 about 20 teeth and is not as long as palpal claw. Eostrum covered 

 with shield and patterned as figured ; peritreme simple, composed of 

 small segments. Propodosomal and hysterosomal shield of about same 

 length, covering most of body ; four pairs of rodlike serrate setae on 

 margin of anterior shield and four pairs of such setae on posterior 

 shield margin; anterior shield with four pairs of dorsal submedian 

 staghorn setae ; three pairs of similar setae on shield on hysterosoma. 

 One pair of eyes. Leg I, 433f(, long; leg IV, only 266/x long. Tarsus I, 

 although superficially like that of Cheletomorpha lepidopteroruTn in 

 general structure, has minute claws; sensory seta rodlike, about as 

 long as segment, guard seta serrate, one-half as long as sensory seta. 

 Tibia with short rodlike sensory seta and three long serrate setae. 

 Length of body 300^, including rostrum 413/^ ; width 213/i,. 



Male. — Similar to female generally but differing in the dorsal shields 

 and type and arrangement of the dorsal setae. Anterior shield not 

 covering all of propodosoma, with four pairs of long rodlike serrate 

 marginal setae and three pairs of dorsosubmedian setae which are sim- 

 ilar to the marginal setae. Two pairs dorsal shields on hysterosoma, 

 a large anterior pair bearing three pairs of setae, and a small posterior 

 pair with two pairs of shorter setae; a pair of dorsosubmedian setae 

 between the anterior pair of shields and pair of setae behind the pos- 

 terior pair of shields. Length of leg I, 300/^, leg IV, 180/>t. Length 

 of body 300(11, including rostrum 400fi ; width 24G/x. 



Type habitat. — On tropical fruits (free-living predator), associated 

 with other mites. 



Type locality. — Kailua, Oahu, Hawaii. 



Type.—V.S.'^.M. No. 1764. 



The type female was collected from papaya fruits, Kailua, Oahu, 

 Hawaii, March 26, 1941, by W. C. Look. Allotype male and 24 para- 

 type females collected on litchi, Lanapape, Kanai, Hawaii, September 

 15, 1943, by T. Nishida. Six female paratypes were collected from 

 loquat, Panoa Koad, Honolulu, Hawaii, February 23, 1943, by T. 

 Nishida; two from Chinese banana, Wailuku, Maui, Hawaii, August 

 31, 1943, by Holdaway and six from Hau, Waikiki, Honolulu, Hawaii, 

 July 8, 1943, by W. Storey. 



The mouth parts and tarsi I are distinctive.
