THE TRICHOID STRUCTURES ON THE CHELICERAE OF THE SHORT-TAILED WHIP-SCORPIONS (SCHIZOMIDA; ARACHNIDA)

Summary

The comb-like cleaning organ on the movable digit of the chelicera in the short-tailed whip-scorpions (Schizomida) is compared with that found in Pseudoscorpions and the Amblypygi. It does not occur on the chelicera of the long tailed whip-scorpions (Uropygi).

The various trichoid structures on the immovable digit of the chelicera of the Schizomida, nearly all on its inner surface, are enumerated and described; some of them are compared with similar structures in the Pseudoscorpions, Solifugae and Ricinulei.
