New atyid shrimp from a Western Australian cave 
of the first male pleopod. Of the atyid shrimps 
currently known from Australia, C. spelunca is 
morphologically most similar to C. themwphila 
which is known from an artesian bore in central 
Queensland (Riek 1953). However, C. thermophila 
possesses more ventral rostral teeth (4-6), more 
spiniform setae (8-11) on the dactylus of the third 
and fourth pereiopods and more hamate setae (15- 
17) on the diaeresis of the uropodal exopod.
