Aphrastochthonius grubbsi Muchmore (troglobite) 
Records: Calaveras Co.: Lost Piton Cave (type locality). 
Comment: This and the following species are the only members of the genus known from California. Previously the only 
species of Aphrastochthonius kn own from the southwestern United States was A. pachysetus Muchmore from Doc Brito 
Cave, Eddy County, New Mexico, 1500 km away. Muchmore (1984) thinks that the forms may have been overlooked by 
collectors because of their small size (1 to 1.5 mm body length) and pale coloration. 
Bibliography: Harvey (1991); McEachem and Grady (1978); Muchmore (1980, 1981a, 1981b, 1984). 
Aphrastochthonius similis Muchmore (troglobite) 
Record: Calaveras Co,: Carlow’s Cave (type locality). 
Comment: This species is similar to, but smaller, than A. grubbsi. Lost Piton Cave and Carlow’s Cave, although less than 
one km apart, are in separate outcrops or “pods” of the Calaveras Assemblage as well as on opposite sides of Coyote Creek. 
This has apparently been a sufficient barrier to allow speciation to occur.
