A review of present knowledge of larvae of the Calopterygoidea (Zygoptera) of the Oriental realm, including keys to families and known genera Orr, Albert G. W. Zootaxa 2024 2024-08-23 5497 2 209 243 9G33Q Hämäläinen 2003 [151,299,1194,1221] Insecta Euphaeidae Cryptophaea Animalia Odonata 25 234 Arthropoda genus  The genus is known from three species occurring in northern Indochina, Thailandand southern China. The larva of one species,  C. vietnamensis(van Tol & Rosendaal), originally placed in  Bayadera, has been confirmed by breeding and is presently being described (T.S. Keetapithchayakul pers comm.). I refrain from pre-empting the results of that study. However it may be noted that this species does share clear synapomorphies with  Bayaderaspp., which it resembles closely, but is nevertheless distinct from known members of that genus.
