The insect was found walking upwards on a plastic table. It was about 3-4cm long, as far as I remember; its been a long time since I encountered it. Spotted near a small shack in the Terai forests. enter image description hereenter image description here

    $\begingroup$ A note as to the animal's size might help (there isn't quite enough here to get that); other than that, I'm certain it's a true bug (Order Hemiptera, Suborder Heteroptera), and believe it to be a stink bug relative (Superfamily Pentatomoidea), but not knowing the Indian fauna I can't go deeper than that. $\endgroup$ – Arthur J Frost May 31 at 6:55

This is a nymph of a shield bug in the Tessaratomidae family, commonly called tassarotimids (or sometimes "giant shield bugs" due to typically being 1.5 - 4.5 cm long).

According to Wikipedia:

They are mostly found in tropical Africa, Asia, and Oceania though a few species can be found in the Neotropics and Australia. There are about 240 species known

Of the subtaxa, only a few genera are even found in India: Empysarus, Neosalica, and numerous in the subtribe Eusthenaria (e.g., Asiarcha, Aurungabada, Carpona, and Dalcantha). A key (Leston (1955)+)to this group of insects is available for purchase or institutional subscription on Wiley

Specific Taxa:

Similar to a comment under the OP's post suggests, this page appears to suggest that the nymph of a Eusthenarian called Eurostus validus (shown below) appears quite similar to the OP's specimen. However, I cannot find definitive record of E. validus being in India.

the availability of useful information (keys, reputable websites, etc.) for this group of insects (especially for India and in English) are extremely limited, so I will just leave you here with the understanding that your insect is a tassarotimid nymph that is closely closely related to Eurostus validus, Eusthenes femoralis or some other member of the Eusthenaria.
