Discussion: This species is readily distinguished from hylas and 

 heliconiae by the subapical pale band on the hind femur and by its 

 more brownish color with paler wing markings. 



The guttatus group 



In this group the base of cell M4 is pale where it borders vein M3+4 

 and Cui; no pale spot anterior to base of vein Mi; antennal sensoria 

 present on segments in, xi-xv or on iii, v., vii, ix, xi-xv; hind tibial 

 ccmb with 5 or 6 spines. 



Panama species: Four: diaholicus Hoffman, Joxi Ortiz, insignis 

 Lutz, and trinidadensis Hoffman.
