A review of present knowledge of larvae of the Calopterygoidea (Zygoptera) of the Oriental realm, including keys to families and known genera Author Orr, Albert G. W. text Zootaxa 2024 2024-08-23 5497 2 209 243 http://dx.doi.org/10.11646/zootaxa.5497.2.3 journal article 10.11646/zootaxa.5497.2.3 1175-5326 13618317 B3C66D95-3585-4920-BE93-A44D33FB2FBB Aristocypha The genus includes 12 species ranging from the Himalayas to southern China and Taiwan , Myanmar , Thailand , Indochina and West Malaysia . Larvae of Aristocypha quadrimaculata (Selys) and A. trifasciata (Selys) were both described and illustrated with habitus and numerous structural details by Kumar & Prasad (1977c) . The larval habitus of A. fenestrella (Rambur) was illustrated by Orr (2005) and a male larva of the same species was described in detail by Orr et al . (2024). Comparisons between these descriptions suggests that the form of the caudal spikes and the presence of longer setae on the scape may distinguish this genus from Heliocypha in known species.
