The new species differs from T. monticola and its synonyms, in possessing higher ventral count 143–150 (versus 113–125 in T. monticola, T. rubiventer & T. albiventer), very faint dorsal longitudinal lines, lacking yellow patch on the neck and the belly being yellowish (versus distinct longitudinal light and dark stripes throughout with a clear yellow patch on the neck with a red belly T. monticola & T. rubiventer).
|Etymology||The specific epithet is a patronym, honouring Dr. Deepak Apte, Director of the Bombay Natural History Society, marine biologist and conservationist for his contribution to conservation, and for his continued support to HB and to the Arunachal Expedition, which led to the discovery of the new species.|
