MITES OF FAMILY CHEYLETIDAE — BAKER 311 



The original description is based on a key to the genera by Berlese. 

 Although he credits the genus and species to Trouessart, who sent 

 him specimens, the description and figure are actually by Berlese, 

 who is here established as the author. 



KEY TO THE SPECIES OF CHELONOTUS 



1. Gnathosoma not covered by propodosoma ; coxae II and III not touching— 2 

 Gnathosoma covered by propodosoma ; coxae I, II, III, and IV contiguous. 



oudemansi, new species 



2. Rostrum sharp, conical; palpal comb slender, with 10 teeth; peritreme com- 



posed of 17 pairs of segments ewingi, new species 



Rostrum blunt, not conical ; palpal comb short, broad, with 5 teeth ; peritreme 

 composed of 9 pairs of segments selenirhynchus Berlese 



CHELONOTUS OUDEMANSI, new species 



Plate 15, Figures 126, 127 



Female. — ^ISiedium-sized mite, blunt on anterior end, and sharply 

 narrowing to rear. Gnathosoma entirely covered by propodosoma. 

 Palpal segments short, broad ; femur broader than long, with simple 

 seta ; genu with simple seta on posterior margin ; palpal claw with a 

 single basal tooth about two-thirds as long as claw; palpal comb 

 slender, with 11 teeth ; sensory ogran on palpal thumb short, lanceo- 

 late. Peritreme made of approximately eight pairs of large segments. 

 Dorsal body setae long, simple, as figured for C. ewingi, new species. 

 Tarsus I 84/i long, tibia I 50/x long ; tarsus I with a long sensory rod- 

 like seta ; guard seta, if present, not seen. Coxae I, II, III, and IV 

 contiguous. Length of body 585 fi; width 328/t. 



Type host. — Baginia tenuis evidens Miller and Hollister (squirrel). 



Type locality. — Pulosembeh, Celebes. 



7^2/^e.— U.S.N.M. No. 1775. 



The single female was taken from a squirrel received from the 

 Celebes by the United States National Museum. 



The covered rostrum and arrangement of the coxae distinguish this 

 species from the others in the genus. 



CHELONOTUS EWINGI, new species 



Plate 15, Figuees 128-130 



Female. — Elongated mite ; body narrowing rapidly anteriorly and 

 posteriorly; rostrum almost triangular; palpi short and swollen. 

 Femur of palpus large, swollen, about as long as wide, dorsal and 

 ventral setae simple; other palpal setae simple; palpal claw large with 

 a single large basal tooth ; a single coarse palpal comb with 10 teeth 

 and a short, broad, lanceolate sensory organ on palpal tarsus. Peri- 

 treme distinctive, as figured. Dorsal body setae long, simple, discern- 

 ible only on lateral margins of body ; three pairs of setae on propodoso-
