Material examined. MARYLAND: Frederick Co., Gum Spring, Brunswick Town Park, DJF, 16 April 1994, 33, 2Ƥ; Montgomery Co.: Edwards Ferry Spring #11, 0.65km NE from mouth of Goose Creek, C& O NHP, DJF, 26 March 1996, 131Ƥ; northeast spring, Three Spring Hollow, C& O Canal, DJF, 1 April 1994, 13; same, southwest spring, 33, 3Ƥ; Washington Co.: Roundtop Hollow Mine #2, DJF, 1 May 1992, 13; same locality, DJF, R. Bartgis, 11 June 1993, 23; spring #1, Seneca Creek State Park, DJF, C. Lee, 16 March 1994, 53, 6Ƥ.

Range. This species has been reported from seven counties in Virginia ( Holsinger & Culver 1988; Lewis 2009). Similar to C. pricei , this species has dispersed from the Appalachians into the Piedmont. The relatively wide range of this species is probably related to its ability to disperse through non-cave groundwaters.
