Diagnosis

Body length 6.6-7.3 mm. Body width 3.5-3.9 mm. Head basic color black. Antennae filiformfiliform:
slender antennae with antennomeres of similar shape
, bi- or tricolored, antennomeres 1-3 yellow, upper sides darkened, antennomeres 4-8 uniformly brussels brown, antennomeres 9-10 uniformly light cadmium, antennomereantennomere:
"segment" of antenna, more or less clearly separated
11 dark apically. Maxillary palpi black or chestnut, labrumlabrum:
the "upper lip" of beetles, a movable sclerite joined under clypeus
black. Pronotumpronotum:
the notum of the prothorax with highly sclerotized pronotal disc
yellow or mustard yellow, transverse, nonfoveate, shagreened with minute tubercles. Scutellumscutellum:
small, usually triangular shield between the bases of elytra
black. Elytra yellow or rufous, with 2-3 black bandsbands:
(here) transverse maculae on the beetle elytra
, 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
are completely reduced on the elytral disk. Elytral epipleura 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 basalbasal:
of or pertaining to the base, as in the first, or basal segment of an appendage; opposite of apical
half. Sutural angle of elytra round, punctation dense, fine. Abdomen yellow. Tarsi and tibiatibia:
<em>(pl. tibiae)</em> the forth part of the beetle leg articulated with femur on the one side and with tarsus on the other side
black. Profemoraprofemora:
the femora of fore legs
bicolored: from half to two-thirds are darkened with black or brown, meso- and metafemorametafemora:
femora of the hind legs
bicolored: approximately apicalapical:
of or pertaining to the apex; opposite of basal
thirds are darkened with black or brown. Aedeagusaedeagus:
the main sclerotized part of the male genitalia; "aedeagus" is used here instead of "median lobe of aedeagus"
symmetric, with four internal sac scleritessclerites:
(here) the sclerotized hooks, spines or plates in the internal sac
.

Potential problems with identification

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.
