DNA barcoding helps Indian scientists confirm new cockroach species
Times of India | 24 March 2026
Kolkata: Scientists from the Zoological Survey of India (ZSI) have identified a new species of cockroach, Neoloboptera peninsularis, from farmlands in Nathachiwadi, Daund, Pune. The discovery utilized a landmark integrative taxonomic approach combining morphology, genitalic study, DNA barcoding, and phylogenetic analysis. This marks a major advance in Indian entomology, moving beyond traditional methods to establish species uniqueness with greater accuracy.
This is the first time since cockroach research began in India in 1758 that a new species has been identified through such a comprehensive modern framework. While identification has long depended on visible physical traits, adding genetic fingerprinting and evolutionary analysis allowed researchers to confirm N. peninsularis as a distinct species.
It is only the third known member of the genus Neoloboptera recorded in India; the others were described in 1865 and 1995. With this addition, India's documented cockroach species count has risen to 190, accounting for roughly 3.8% of global diversity. The species is endemic to India.
The discovery highlights how much remains undocumented even in well-studied regions. Maharashtra, despite its ecological range, has seen only 13 original cockroach species descriptions. Researchers believe DNA-based tools will accelerate discoveries and improve identification confidence nationwide.
The study was conducted by ZSI scientists from Pune and Chennai in collaboration with Prof Ramkrishna More Arts, Commerce and Science College, Pune. The team—comprising A Shabnam, M Senraj, Sahil Shikalgar, Rashmi Morey, and KP Dinesh—said the work signals a new era for biodiversity documentation in India.
