The specimen is under the genus Heterocarpus obtained from Indian coast between the depth range of 250-350. I would like to know the species level identification, based on rostrum deformed nature character of the Heterocarpus, it is doubtful. I Kindly request to identify the species.
Thanking you
Kuberan
It is difficult to ID the species from the pictures you provided. However, if anyone can do it, it would be C. Fransen at the Naturalis Biodiversity Center in Leiden: C. H. J. M. Fransen
I also attached a couple of keys that may help with your identification.

I would indicate these references: Tavares (1999), Cardoso and Serejo (2007) and Rego and Cardoso (2010). Or try a contact with Flavio A. Alves-Júnior
Dear Kuberan, really by photography this specimen resemble the Heterocarpus nasicus. But look for more details in Timofeev (1993). So, in other hand if your specimen no fits well with the H. nasicus, try to see the Genus Eugonatonotus, based on the rostrum shape which is very short as in this photo.
But remember, in several shrimps the rostrum shape is very doubtful probably broken in battle or by predatory action, so try to see more details in abdominal somites (as sulcus or carena) and by exopodit in third maxiliped as well.
Best wishes to all!
Dear Flavio A. Alves-Júnior
Like we earlier discussed, it not fits with H. nasicus. I also crossed over with the Genus Eugonatonotus, interesting group. As you said let me go with this group for the characterization. Thank you once again.
