of 0.19 mm (range 0.13-0.23 mm) in C. kapuhili. The relationship 

 of the length of the abdomen to the length of the body (average 

 total length divided by average length of abdomen) is 4.94 in C. 

 laticaudus and 10.2 in C. kapuhili. The spinelike projection of 

 the postantennal process in C. laticaudus is elongate and distally 

 pointed, while in C. kapuhili it is short and distally rounded. The 

 fom"th thoracic leg of C. laticaudus has a friUed membrane at the 

 base of each spine; with the exception of the innermost terminal 

 spine, these membranes are absent in C. kapuhili. 



The species name is derived from "Kapuhili," the Hawaiian name 

 for several of the chaetodontids or butterfly fishes, the host of the 

 species.
