MCZ, holotype, male, verified
Body length 6.4-6.5 mm. Body width 3.3-3.4 mm. Head basic color green. Antennae serrateserrate:
in reference to antennae, saw-like, often with a sharp ridge on the outer margin
, with thickened antennomeres 4-8, bi- or tricolored, antennomereantennomere:
"segment" of antenna, more or less clearly separated
1 uniformly pale olivine, antennomeres 2-3 yellow, upper sides darkened, coloration of antennomeres 4-8 gradually infuscated, antennomeres 9-10 yellow, partly infuscated, antennomereantennomere:
"segment" of antenna, more or less clearly separated
11 brussels brown. Maxillary palpi yellow, labrumlabrum:
the "upper lip" of beetles, a movable sclerite joined under clypeus
black or amber brown. Pronotumpronotum:
the notum of the prothorax with highly sclerotized pronotal disc
green or cress green, yellowish in the center, 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 green, maculatemaculate:
(here) marked by maculae or patches of a different shape and size, usually clearly separated from each other
with three diffuse round sulphur yellow maculae on each elytronelytron:
<em>(pl. elytra)</em> the fore highly sclerotized wing of beetle
. Elytral epipleura yellow basally, green apically. Elytral surface with five distinct sinuatesinuate:
curved in some way
sulci, strongest behind the humeral callushumeral callus:
<em>(pl. calli)</em> more or less marked tubercle or knob on the anterobasal angle of elytron
and extending beyond the middle. Sutural anglesutural angle:
the posterior angle or apex of the elytron near the suture
of elytra dentiform, punctation scattered, fine. Abdomen pale olivine. Tarsi yellow, tibiae bicolored, pale olivine, outer edge with piceous or testaceous line, or extensively darkened. Femora uniform yellow. Aedeagusaedeagus:
the main sclerotized part of the male genitalia; "aedeagus" is used here instead of "median lobe of aedeagus"

Cucumis melo L. (Krysan & Smith, 1987b)
Diabrotica linsleyi Krysan & Smith, is very similar to D. selecta Jacoby and D. tortuosa Jacoby. They can be separated by the following features: the antennae are bicolored in D. linsleyi, but unicolorous in D. selecta and D. tortuosa; elytra in D. linsleyi are with distinct discal sulci, which lack in D. selecta; there are three yellow maculae on each elytronelytron:
<em>(pl. elytra)</em> the fore highly sclerotized wing of beetle
in D. linsleyi, but four maculae in D. tortuosa.
