ETYMOLOGY: Although Bousfield (1963) did not indicate the 

 origin of the name "grandimanus" in the original description, we 

 presume that he was making reference to the "very large gnathopods" 

 that characterize this species. 



REMARKS: Holsinger (1972) listed this amphipod as a member 

 of the obliquus-richmondensis group.

Crangonyx hobbsi Shoemaker 

 HOBBS' CAVE AMPHIPOD 



Crangonyx hobbsi Shoemaker, 1941. Charleston Museum Leaflet 

 16:457. TYPE LOCALITY: Huggins Cave, Alachua County, Florida. 

 Holotypic male (USNM 79362), paratypic female (USNM 109623), 

 Horton H. Hobbs, Jr. (coll.). 



DISTRIBUTION: WOODVILLE, OCALA (Upper Suwannee, Lower 

 Suwannee, Orange Lake, Marion, Withlacoochee, Gulf Coastal Lowlands), 

 and MIAMI FAUNAS. This amphipod is widespread in limestone 

 areas of the Florida peninsula, east of the Apalachicola River, and on 

 occasions can be abundant at certain sites. Its distribution coincides 

 with that of Crangonyx grandimanus. The species was listed as a 

 Species of Special Concern by the Florida Committee on Rare and 

 Endangered Plants and Animals (Franz 1982) because of its dependence 

 on specialized subterranean habitats and its limited distribution; it is 

 a candidate for federal listing (Wood 1992).
