 Presence of stridulatory files on occipital region of 



head unknown (heads retracted) . Males lacking prosternal 



foveate punctures in front of procoxae; females with few 



punctures, often weakly impressed. 



Variation . Little variation was observed in size, 

 shape, and color pattern. Elytral spots are occasionally 

 connected to form bands. 



A female from Yucatan, Mexico, has coarser punctation, 

 2 basal pronotal spots, scutellar and central spots broadly 

 connected to the suture, and the subhumeral spot elongate, 

 connected to base laterally (Fig. 67). This specimen may 

 represent a distinct taxon. More specimens and study of 

 male genitalia are needed before any separation can be made. 

 At present, it is considered a variety of I. elegantulus .
