Diabrotica martinjacobyi is very similar to D. curvilineata Jacoby. They can be separated by the following features: elytra in D. curvilineata are maculatemaculate:
(here) marked by maculae or patches of a different shape and size, usually clearly separated from each other
with two small black spots on each elytronelytron:
<em>(pl. elytra)</em> the fore highly sclerotized wing of beetle
, in D. martinjacobyi elytra are maculatemaculate:
(here) marked by maculae or patches of a different shape and size, usually clearly separated from each other
with two short black lines. The shape of the internal sac sclerite 6E is the most reliable feature that allows distinguishing two species.
