Diagnosis

Body length 6.1-7.0 mm. Body width 3.0-3.8 mm. Head basic color yellow or black. Antennae filiformfiliform:
slender antennae with antennomeres of similar shape
, bi- or tricolored, antennomereantennomere:
"segment" of antenna, more or less clearly separated
1 yellow, antennomeres 2-3 yellow, upper sides darkened, antennomeres 4-8 cinnamon brown, antennomeres 9-10 light cadmium, antennomereantennomere:
"segment" of antenna, more or less clearly separated
11 dark apically. Maxillary palpi and labrumlabrum:
the "upper lip" of beetles, a movable sclerite joined under clypeus
black or piceous. Pronotumpronotum:
the notum of the prothorax with highly sclerotized pronotal disc
yellow or mustard yellow, subquadrate, weakly bifoveate with wide shallow foveae, not shagreened. Scutellumscutellum:
small, usually triangular shield between the bases of elytra
yellow. Elytra yellow or rufous, with humeral and sutural black vittae and with 2 short lines or small spots in apicalapical:
of or pertaining to the apex; opposite of basal
third of each elytronelytron:
<em>(pl. elytra)</em> the fore highly sclerotized wing of beetle
. Vittae and maculae may be reduced to variable extent, sometimes elytra uniformly yellow. Epipleura completely yellow. Sutural anglesutural angle:
the posterior angle or apex of the elytron near the suture
of elytra round, punctation scattered, fine. Abdomen yellow. Tarsi and tibiae black, piceous or chestnut. 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 apicicornis Jacoby is similar to D. fulvicornis Jacoby. They can be separated by the following features: tarsi and tibiae are black in D. apicicornis, but yellow in D. fulvicornis.
