Diabrotica costaricensis Derunkov, Prado, Tishechkin, Konstantinov is very similar to D. viridicollis Jacoby, and D. dmitryogloblini. They can be separated by the following features: male metatibia spurmetatibia spur:
a short process at the apex of metatibia
elongate in D. costaricensis, but short in all other species; head is black in D. costaricensis, green with brownish olive vertexvertex:
the upper part of the head capsule behind the eyes
in D. dmitryogloblini and yellow with chestnut vertexvertex:
the upper part of the head capsule behind the eyes
in D. viridicollis; pronotumpronotum:
the notum of the prothorax with highly sclerotized pronotal disc
is foveate in D. costaricensis, but nonfoveate in D. viridicollis; two basalbasal:
of or pertaining to the base, as in the first, or basal segment of an appendage; opposite of apical
bandsbands:
(here) transverse maculae on the beetle elytra
on elytra conjunct with each other for forming round macula on each elytronelytron:
<em>(pl. elytra)</em> the fore highly sclerotized wing of beetle
, while black bandsbands:
(here) transverse maculae on the beetle elytra
are reduced to a substantial degree in D. viridicollis and D. dmitryogloblini; body shape is more convex and wider in D. costaricensis than in all other species; D. costaricensis is larger than all other species.
