Cactus Spindle Snail (Cylindrella pilocerei)

The enigmatic Cactus Spindle Snail was described in1841; it is known from somewhere in Mexico (Guanajuato and Hidalgo?) and apparently was found hiding under the conspicuously elongated, hair-like modified spines of the so-called Old Man Cactus (Cephalocereus senilis (Haw.) Pfeiff.).:

C. pilocerei lebt auf Cactus, namentlich Pilocereus senilis.” [1]


C. pilocerei lives on Cactus, namely Pilocereus senilis.

The taxonomic status of this species is somewhat questionable and, if it ever existed, it is now possibly extinct. [2]
