The paper describes a new species of the conodont form-genus Neospathodus Mosher, under the specific name N. praekummeli sp. nov. The presently recorded new species has a close morphologic and biostratigraphic relation with the well-known Dienerian guide-species N. kummeli Sweet.
In the Lower Triassic sequence of Spiti the first appearance of N. praekummeli sp. nov. marks the base of Ophiceras bed. It is likely that N. kummeli Sweet has evolved from N. praekummeli sp. nov. near the base of Ophiceras bed.

The history of research on the chronostratigraphic status of Otoceros fauna of Himalaya has been traced and the brachiopod, pelecypod and ammonoid biostratigraphy of the classical Otoceras bed of Himalayan sections has been critically reviewed. It is observed that the impact of over-all change in the palaeobiological communities, in the sense of change from Palaeozoic to Mesozoic, is better discernible at the base of Ophiceras bed. This megafaunal observation is supported from the vertical distribution of conodonts. This calls for revision of the traditional view of placing the Permian-Triassic boundary at the base of Otocerus bed.- Conodont Biostratigraphy of the Lower Triassic in Spiti Himalaya, India
