New Species: Acanthosaura syrax (English)
नया प्रजाति: Acanthosaura syrax (हिन्दी)
Acanthosaura syrax, commonly called the Syrax mountain horned dragon, is a newly described lizard species from Mae Wong National Park in northern Thailand. The species was formally published in the taxonomy journal ZooKeys on 2 August 2026.
Discovery and Taxonomy (English)
खोज और वर्गीकरण (हिन्दी)
Thai researchers Poramad Trivalairat and Krittiya Trivalairat collected the first three specimens on 23 April 2025 at a high-elevation forest site in Mae Wong National Park. They added five more specimens in May 2025, so the species description is based on eight specimens in total. A. syrax is the 23rd recognised member of the genus Acanthosaura, which belongs to the family Agamidae.
Key Identification Features (English)
मुख्य पहचान विशेषताएँ (हिन्दी)
- DNA evidence: mitochondrial genes ND2 and COI were used; genetic distance from closest relatives ranges 14%–28%.
- Distinctive physical traits: smallest neck and back crest scales known in the genus and no black eye patch.
- Colour and reproduction: yellowish-green body and relatively large egg clutches compared with congeners.
Habitat, Range and Naming (English)
आवास, क्षेत्र और नामकरण (हिन्दी)
A. syrax occupies a restricted, narrow high-altitude forest range in northern Thailand. The study specifies elevations above 1,300 metres (some reports cited >1,000 m). The species name syrax refers to Syrax, a yellow dragon from the TV series House of the Dragon, chosen because of the lizard’s colour, small size and reproductive traits.
Exam Quick Facts (English)
परीक्षा के लिए प्रमुख तथ्य (हिन्दी)
- Publication: ZooKeys (peer-reviewed open-access journal) — formal description published 2 August 2026.
- Collectors & dates: Poramad & Krittiya Trivalairat; first collected 23 April 2025; total 8 specimens by May 2025.
- Taxonomy: Genus Acanthosaura (23rd species); Family Agamidae.
- Genetic markers: COI and ND2 (mitochondrial genes used in reptile DNA barcoding).
- Habitat: Mae Wong National Park, Thailand; high-altitude forest above ~1,300 m; restricted range — relevant for endemism and conservation questions.
Why this matters for exams and conservation (English)
परीक्षा और संरक्षण के लिए महत्व (हिन्दी)
New restricted-range mountain reptiles like A. syrax are important in questions on biodiversity, endemism and habitat vulnerability. Remember: Agamidae includes arboreal and semi-arboreal lizards across Asia, Africa and Australia, and Mae Wong National Park is a protected forested area in Thailand often referenced in biogeography and conservation contexts.
