Diagnosis

Body length 5.6-6.3 mm. Body width 3.0-3.3 mm. Head basic color black. Antennae filiformfiliform:
slender antennae with antennomeres of similar shape
, bi- or tricolored, antennomereantennomere:
"segment" of antenna, more or less clearly separated
1 and 9-10 sulphur yellow, antennomeres 2-3 yellow, with upper sides darkened, antennomeres 4-8 uniformly cinnamon brown, 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, subquadrate, weakly bifoveate, with wide shallow foveae, shagreened with minute wrinkles. Scutellumscutellum:
small, usually triangular shield between the bases of elytra
black or amber brown. Elytra yellow or rufous, with three sharp-edged metallic black blue or green bandsbands:
(here) transverse maculae on the beetle elytra
connected together and forming two round maculae, in basalbasal:
of or pertaining to the base, as in the first, or basal segment of an appendage; opposite of apical
area of elytra and in the middle. Elytral epipleura completely yellow. Sutural anglesutural angle:
the posterior angle or apex of the elytron near the suture
of elytra obtuse-angled, punctation scattered, coarse. Abdomen yellow. Tarsi and tibiae black or piceous, femora yellow. Aedeagusaedeagus:
the main sclerotized part of the male genitalia; "aedeagus" is used here instead of "median lobe of aedeagus"
symmetric, with five internal sac scleritessclerites:
(here) the sclerotized hooks, spines or plates in the internal sac
.

Potential problems with identification

Diabrotica waltersi is very similar to D. elegantula Baly. They can be separated by the following features: the body of D. waltersi is more convex and shorter than in D. elegantula; the medium maculae are almost round in D. waltersi, while transverse in D. elegantula; the color of the bandsbands:
(here) transverse maculae on the beetle elytra
is usually black metallic blue in D. waltersi, but black metallic green in D. elegantula.
