First record of androchrome females of Anax nigrofasciatus (Odonata: Aeshnidae) from Bhutan and notes on its occurrence in Asia

“…Joshi & Agashe (2020) showed that colour variation could be related to genetic polymorphism and ontogenic change where an immature Agriocnemis pygmaea (Rambur, 1842) was observed to be heteromorphic but acquired andromorphic colours on reaching sexual maturity. In European Zygoptera, andromorphs have been reported in 54 % of genera ( Cordero & AndrÉs 1996) but they are rare in Anisoptera, and most occur in libellulid genera such as Crocothemis, Neurothemis, Sympetrum, and Urothemis ( Kumar 1988; Kotarac 1996; Corbet 1999; Payra 2019a, 2019b; Willink et al 2019; Joshi et al 2020; Prasad et al 2000; Andrew 2013). Additionally, among aeshnids, four studies of androchrome females from the Palaearctic region have been made on Aeshna grandis (Linnaeus, 1758) , Anax guttatus (Burmeister, 1839) , A. immaculifrons Rambur, 1842, and A. imperator Leach in Brewster, 1815 ( Fincke et al 2005) .…”
