Diagnosis

Body length 7.2-7.3 mm. Body width 3.7-3.8 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, antennomeres 4-8 gradually infuscated, antennomereantennomere:
"segment" of antenna, more or less clearly separated
11 dark apically. Maxillary palpi yellow or yellow ocher, 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 light cadmium, subquadrate, deeply bifoveate, not shagreened. Scutellumscutellum:
small, usually triangular shield between the bases of elytra
yellow. Elytra yellow or rufous, with two metallic black blue bandsbands:
(here) transverse maculae on the beetle elytra
, one on base of elytronelytron:
<em>(pl. elytra)</em> the fore highly sclerotized wing of beetle
, another - behind middle. Elytral epipleura completely yellow, sutural anglesutural angle:
the posterior angle or apex of the elytron near the suture

Potential problems with identification

Diabrotica josephbalyi is very similar to D. militaris Jacoby, D. reysmithi and D. fasciata Kirsch. They can be separated by the following features: band color is metallic black blue in D. josephbalyi, but metallic black green in D. militaris and D. fasciata; elytra are without round yellow spot on the basalbasal:
of or pertaining to the base, as in the first, or basal segment of an appendage; opposite of apical
band in D. josephbalyi, but with spots in D. militaris and in D. reysmithi; the size and the shape of the band edges is different in all four species. The shape of the internal sac scleritessclerites:
(here) the sclerotized hooks, spines or plates in the internal sac
allows distinguishing Diabrotica josephbalyi from all other species.
