Enderleinellus dremomydis Ferris 



Enderleinellus dremomydis Ferris, Contributions toward a monograph of the 

 sucking lice, pt. 1 (1919), p. 29, fig. 16, 1920; The sucking lice, p. 108, 

 1951. 



This species was described from two females found on Dremomys 

 pernyi, West Szechuan, China. 



New record: One female from Dremomys rufigenis, loei: Dan 

 Sai, Kok Sathon, Phak Khi Nak Mountain, March 29, 1955, RE-5189. 



This Thai record is the first since the original description. The 

 specimen agrees well with the original description and the female 

 paratype in the U.S. National Museum collections. The male of 

 dremomydis remains unknown.
