Echinarachnius parma var. obesa H. L. Clark 



Although specimens in the U.S. National Museum (USNM 34315, 34214, 

 34213, and 34291) and specimens in the Museum of Comparative Zoology 

 (MCZ 2322, 2323, 2324,4200, 4216, and 4217) were marked type material 

 and so cataloged, H. L. Clark clearly stated, in his original description in 

 1914, that this is not a species or subspecies, but at most a variety. 

 Mortensen, in his Monograph, concurred in this opinion, even though he 

 lists it as Echinarachnius parma obesa, as if it were a recognized sub- 

 species. The USNM specimens have been removed from the type collec- 

 tion and placed in the regular collection.
