Mexico . Lichen on tree, coll. Miguel Angel Gonzalez Botello, 3 May 2014 . Comments: Echiniscus tamus Mehlen, 1969 was described from North America ( Texas , USA ). Our single specimen is similar to the Texan specimen ( Mehlen 1969 ; Miller & Mehlen 2007 ), but differs by having a basal spur on the internal claws. This is possibly a new species, but for final identification a larger number of specimens are required.
