Sarcoptiformes

Discussion: Czenspinskia heterocomus (Michael) was beaten off 

 oak trees in Hampshire, England, and was also taken in considerable 

 numbers in the moss of a squirrel's summer nest. Michael 1903 reared 

 a great many by feeding them 

 pieces of fungus. Czenspinskia 

 lordi Nesbitt 1946 was found on 

 apple trees in Nova Scotia. They 

 live in colonies near the midribs 

 of the leaves, feeding on vegetable 

 matter and apparently overwin- 

 tering beneath lichens and old 

 oyster-shell scales. No males have 

 been found and the mite appar- 

 ently reproduces parthenogeneti- 

 cally.

Diagnosis: These mites have a propodosomal shield and a shiny skin. 

 On the posterior part of the propodosoma is a transverse row of four 

 setae of equal length. No cervical setae are present, but a pair of ver- 

 tical setae is present. The legs are short and robust. All tarsi have 

 stalked claws and caruncles. Ventro-distally the tarsi have one, and 

 terminally two very strong spines (especially on tarsi i and ii). Male 

 and female genital openings are between coxae iv. The male does not 

 have adanal suckers or suckers on tarsi iv but does have a latero- 

 ventral sucker on tarsus i.
