I think it was an accidental inclusion. What I want to resolve is whether it is an Indian species or US species. The insect was alive inside the plastic cover.
get it identified and also assess it for its quarantine importance, even Pratapan sir at ZSI and NBPGR at new delhi can also help you in identifying this insect
Its a stored product insect. Hope you ve not thrown away the package in which you found the the insect. There may be some eggs there if it was a female. Suggest you put some wheat flour/ peanuts in the pack. Watch for some weeks. you may have some adults emerging in few weeks.
Dear Mr. Sumodan I agree with Dr.Andras it s far to be tribolium, as you said it can be there accidentaly.i think this species looks more like Bostrichidae, its close to wood boring beetle .
