, connected into ring-shape maculae or reduced to a few spots on each elytronelytron:
<em>(pl. elytra)</em> the fore highly sclerotized wing of beetle
, sometimes the bandsbands:
(here) transverse maculae on the beetle elytra

Diabrotica redfordae is very similar to D. fenestralis Jacoby and D. morosa Jacoby. They can be separated by the following features: elytral epipleura in D. redfordae are completely black, narrow interior edge is pale or darkened from basalbasal:
of or pertaining to the base, as in the first, or basal segment of an appendage; opposite of apical
third to half, but completely yellow in D. fenestralis; femora of D. redfordae are bicolored, but the legs are entirely black in D. morosa. On average, Diabrotica redfordae is larger than both other species.
