R. E. Elbel, collector. One paratype female from Tamiops mac-

D. C. and E. B. Thiirman collectors, 



Holotype deposited in the collections of the U.S. National Museum,

Diagnosis: E. corrugatus is close to E. malaysianus Ferris and 



E. dremomydis Ferris. The thoracic sternal plate and male genitalia 

 are much like those of malaysianus. It is easily distinguished from 

 malaysianus in that paratergal plates II-V are heavily ridged and 

 the spiracles are not particularly enlarged. E. corrugatus has the 

 head almost as broad as long but not noticeably longer, and has 

 spiracles on abdominal segments 3-8, not 3-5 as does malaysianus. 

 In corrugatus, large distinct paratergal plates are present on segments 

 2-5, a very small plate is present on segment 6, and areas of sclerotiza- 

 tion occur around the spiracles on segments 7 and 8. E. malaysianus 

 completely lacks plates on segments 6-8. E. corrugatus is distinct 

 from E. dremomydis, which has paratergal plates on segments 2-6, 

 in that dremomydis lacks rugosities on these plates, has the plates 

 differently shaped, and has different setation.
