Integrating Morphological, Molecular and Whole Genome (Mitogenomic) Approaches in Indian Lepidoptera

India, with its extensive and diverse biogeographical regions, supports a remarkably rich Lepidopteran diversity, particularly in the Himalayas, Western Ghats and Northeastern areas. Despite this vast biodiversity, taxonomic studies on Indian Lepidoptera have primarily relied on traditional morphological approaches, with limited integration of molecular and genomic techniques. The lack of comprehensive genomic datasets for Indian Lepidoptera presents a major hurdle in resolving taxonomic ambiguities, particularly in cryptic and endemic species. Moreover, challenges such as habitat fragmentation, climate change and human induced disturbances have intensified conservation concerns, emphasizing the need for more precise taxonomic evaluations. Recent advancements have focused on addressing these limitations by incorporating morphological, molecular and whole genome (Mitogenome) methodologies into Lepidopteran research in India. The sequencing of complete mitochondrial genomes and nuclear markers for selected species has provided valuable insights into phylogeography and evolutionary relationships. However, large scale genomic initiatives are yet to gain substantial traction in India. This chapter shall provide a detailed review of Lepidoptera taxonomy, emphasizing integration of morphological, molecular and whole genome approaches. Special attention shall be given to Indian Lepidoptera, discussing existing knowledge gaps, recent progress and future directions. By combining classical taxonomy with molecular and genomic tools, this chapter aims to refine taxonomy and conservation efforts in India.
