Ptomaphagus cavernicola Schwarz, 1898
Explanation of Names
cavernicola (L). 'cave dweller' (1)
Numbers
52 spp. n. of Mex. (2)
Range
c., se. US (TX, OK, AR, MO, IA, SC, FL) / Mex (Peck 1982)
Type Locality: Marble (=Marvel) Cave, Stone Co., Missouri
Habitat
frequent in caves
Life Cycle
In caves, P. cavernicola is most abundant upon feces of bats or raccoons, or upon dead bat carcasses. Occasionally it occurs on wet, rotten wood. (Barr 1963)
Remarks
This is a fully-eyed and functionally-winged species known (w/ one SC exception) only from caves in a largely disrupted but crescentric dist. from Mex. to IA to FL. (Peck 1973)
The lack of significant variation in the cave pop. may suggest that the dist. was achieved during and shortly after the Wisconsinan glacial, and that cave restriction occurred during the Recent. (Peck 1982)
