abstract：:The sensory organs on the tarsi of the antenniform first legs of the whip spider Admetus pumilio C. L. Koch (Amblypygi, Arachnida) were examined with the scanning and transmission electron microscope. At least four different types of hair sensilla were found: (1) thick-walled bristles, which have the characteristics o...

abstract：:On dark-adaptation of the 11-day adult eye, the rhabdomers move towards the cuticle. Each c-c-r array (of tandem centrioles and ciliary root) maintains its position relative to the rhabdomere, and the length of the root is apparently unchanged. The close association of the array with the rhabdomere is not established ...
