Westport, a single specimen found amongst moss from Knappagh Wood 

 in July. 



This is a beautiful and easily recognized species. It is a bright scarlet 

 mite of long oval form, with a transparent chitinous collar which projects 

 from the anterior end of the body and partly encloses the capitulum. 

 The skin is finely punctured and is also distinctly reticulated. An excellent 

 figure of the species is given by Berlese in the above reference.

 Apennines, Berlese).
