I think it is more closer to specimens of Trichosanthes khasiana in GBIF (One and two).

Perhaps we will have to look for flowers before we assign this specimen to any Trichosanthes species. The crucial difference is fimbriate corolla of T. bracteata (Lam) Voight (syn T. palmata Roxb.) in which fruits are without costae, T. wallichiana similarly without any costae. Not much images are available for T. khasiana Kundo, which was created based on type by Hooker and Thoms. as indicated here https://psimg.jstor.org/fsi/img/pdf/i0/10.5555/al.ap.specimen.k000102019_normal.pdf, distributed as var of T. multiloba in FBI

Costae are visible in only fruit seen, so it might be T. costata as suggested by Saroj ji, but as I mentioned above flowers are essential for confirmation.
