Year: 2026

Type: article

Abstract: The present study highlights the first record of Gynacantha basiguttata Selys, 1882 from India, and significantly indicates a range extension and extends its known geographical distribution. Also known as the Spoon-tailed Duskhawker, the species was identified by dorsal diagnostic morphological characters and spoon-shaped cerci with on-site photographs taken on 16 October 2024 alongside a road-side vegetation about the Miao-Vijaynagar road on a cloudy day at Namdapha National Park and Tiger Reserve, in Arunachal Pradesh, India. Based on photographic evidence for same date, Mahesh et al. (2026) also reported the first confirmed sighting (after 110 years) of Gynacantha khasiaca (MacLachlan, 1896), from Arunachal Pradesh with inclusion of 3 photographs. One of the images from it is herein reassigned to Gynacantha basiguttata Selys, 1882, thereby indicating a self-rectification.
