New species of dragonfly discovered in Kerala’s rubber plantations, named Lyriothemis keralensis

1. At a Glance

• A new dragonfly species, Lyriothemis keralensis, common name "Slender Bombardier," has been formally described from Kerala's Western Ghats lowlands. [1][2]
• It belongs to family Libellulidae (order Odonata) and was found in shaded rubber and pineapple plantations in Ernakulam district. [1]
• Relevant for UPSC as a recurring species-discovery/taxonomy current-affairs item, testing biodiversity, Western Ghats hotspot status, and naming conventions (species epithet after a state). [1]
• Demonstrates the role of citizen-science-linked institutions (butterfly/odonate societies) in India's taxonomic research output. [2]

2. Why in the News

• Published in The Hindu (Kerala/International print edition), 10 February 2026, reporting the formal scientific description of the new species. [1]
• Findings published in the peer-reviewed International Journal of Odonatology, Vol. 29, pp. 19–36. [2]

3. Background & Evolution

• The species was first spotted in 2013 near Varappetty, Kothamangalam, Ernakulam district, Kerala, but was misidentified for over a decade as Lyriothemis acigastra ("Little Bloodtail"), a species widespread in northeastern India. [1]
• Over a decade of fieldwork and taxonomic study followed before formal description. [2]
• Type specimens have been deposited in the Biodiversity Lab Research Collections, held at the National Centre for Biological Sciences (NCBS), Bengaluru. [2]

5. Multi-Dimensional Analysis

Environmental

• Highlights how modified/plantation landscapes (rubber, pineapple) can harbour undiscovered native biodiversity, not just untouched forest. [1]
• Researchers flagged the need for careful land-use practices in plantation zones to ensure species survival — links land management to conservation outcomes. [1]
• Underlines Kerala/Western Ghats status as a global biodiversity hotspot, still yielding new taxa.

Scientific/Technological

• Case of taxonomic correction — decade-long misidentification resolved through detailed morphological/molecular study, showing the iterative nature of taxonomy. [1]
• Collaborative, multi-institutional research model: an NGO (Indian Foundation for Butterflies), a state agricultural university, a specialist society (Society for Odonate Studies), and a national research institute (NCBS) worked jointly. [1]

Administrative/Governance

• Discovery emerged from non-forest-department institutions (NGOs, universities, citizen-science-linked societies) rather than a central government wildlife body, reflecting decentralized biodiversity research capacity in India.

6. Recent Developments (last 12-18 months)

• February 2026: Formal publication and public reporting (The Hindu, 10 Feb 2026) of Lyriothemis keralensis as a new-to-science species. [1][2]
• Study published in International Journal of Odonatology Vol. 29 (2026 issue), pp. 19–36. [2]

7. Prelims Hooks

• Lyriothemis keralensis is nicknamed the "Slender Bombardier." [1]
• Belongs to family Libellulidae, order Odonata. [2]
• Type locality: Varapetty, near Kothamangalam, Ernakulam district, Kerala. [1]
• First observed in 2013, but formally described only in 2026 — over a decade of misidentification. [1]
• Was earlier confused with Lyriothemis acigastra ("Little Bloodtail"), found in northeastern India. [1]
• Habitat: vegetated pools/irrigation canals in shaded rubber and pineapple plantations. [1]
• Males are blood-red with black markings; females are yellow with black markings and bulkier. [1]
• Adults visible only in the Southwest monsoon (late May–end August); larval stage persists rest of the year in canals/pools. [1]
• Published in the International Journal of Odonatology, Volume 29, pages 19–36. [2]
• Researchers involved: Dattaprasad Sawant, A. Vivek Chandran, Renjith Jacob Mathews, Krushnamegh Kunte. [1]
• Institutions involved: Indian Foundation for Butterflies (Bengaluru), Kerala Agricultural University's College of Forestry, Society for Odonate Studies (Kerala), NCBS (Bengaluru). [1]
• Type specimens deposited at NCBS Biodiversity Lab Research Collections, Bengaluru. [2]
• Species epithet "keralensis" recognises Kerala's biodiversity. [1]

10. Common Errors / Trap Areas

• Confusing Lyriothemis keralensis with Lyriothemis acigastra ("Little Bloodtail") — the species it was misidentified as for over a decade. [1]
• Assuming discovery location was untouched forest — it was actually plantation habitat (rubber/pineapple), not pristine wilderness. [1]
• Misattributing the lead research institution — it involves NCBS, Kerala Agricultural University, and NGOs, not a central government ministry. [1]
• Confusing "first observed" (2013) with "formally described/published" (2026) — a decade-long gap. [1]
• Assuming year-round visibility — adults are seasonal (monsoon only); larvae persist year-round. [1]
