OTHER COMMON NAMES: Orange-Seminole Cave Crayfish. 

 We prefer the use of the name Orlando Cave Crayfish because the 

 entire world distribution occurs within the Orlando metropolitan area. 

 It brings into focus the precarious conservation status of this species 

 in one of the most rapidly expanding urban areas in Florida. 



DISTRIBUTION: ST. JOHNS RIVER FAUNA (Wekiva). This 

 crayfish is found in groundwater habitats in a limestone area along 

 the Wekiva River in Orange and Seminole counties, Florida. It was 

 proposed as Threatened by the Florida Committee on Rare and Endangered 

 Plants and Animals (Franz 1982). 



SPECIFIC LOCALITIES: Orange County: Apopka Blue Hole 

 (USNM), Wekiwa Springs (USNM), well at Long Lake (RF). Seminole 

 County: Palm Springs (USNM), well at Altamonte Springs (RF), well 

 at Lake Brantley-type locality (ZIAS, Lonnberg 1894, 1895). 



ETYMOLOGY: The name acherontis apparently refers to "Acheron," 

 the name of the river of woe in Greek and Roman mythology, one of 

 the five rivers that surrounds Hades, across which Charon ferried the 

 dead.
