(Fig. 89a); base of flagellum straight and swollen, sclerite 



at base elongate, parallel-sided (Fig. 89b-d) (4 dissected) . 



Female genitalia with spermathecal head arched, kidney- 

 shaped; tail narrowed, angled onto itself (Fig. 89e) (2 

 dissected) . 



Stridulatory files not present on occipital region of 

 female head; males heads retracted, file presence unknown. 

 Females with foveate punctures on prosternum in front of 

 procoxae; males lack these punctures. 



Variation . The size and amount of connection between 

 the elytral spots vary. On some specimens the elytra are 

 banded, others are spotted. The free pronotal spot remained 

 consistent throughout the specimens studied. There was no 

 indication that this spot is a fusion of 2 spots as seen on 

 I. episcaphulinus Gorham. It is always one elongate spot. 



On specimens from Guatemala and Panama, the elytral 

 spots are in a straight transverse line. On specimens from 

 Colombia and one from Panama, the elytral spots are 

 transverse, anteriorly convex arch.
