tude 1220 meters. It is the only one of the 
four species in which there is a well-developed 
paradont on the tibia of the palp. It resembles 
C. delitescens and C. grandjeani in the fusiform 
sensilla. It resembles C. hurdi in the filiform 
shape of the major setae. Whether or not the 
paradont is a new seta in this species or whether 
it is a modified normal seta is difficult to say. 
Cooreman showed three normal setae on the 
posterior surface of the palpal tibia and two on 
the anterior surface, in addition to the odontus 
and paradont, making a total of seven setae for 
the tibia. In the other three species, there are 
six setae in addition to the odontus, but none 
of these assumes the character of a paradont.
