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.

The larva of S. petiolata Selys was described by Orr et al . (2024) and differs clearly from known chlorocyphid larvae in a number of characters, including possessing a very long prementum, proportionally very long antennae, reduced anterior tubercles on the pronotum, long, thin evenly tapered caudal spikes, numerous small spines on the venter of the terminal abdominal segments and distinctive outer female gonapophyses. The other species of the genus, S. striata Orr , is confined to Brunei and adjoining areas of Sarawak and its larva is expected to be very like that of S. petiolata , with the caveat that closely related species can show surprising differences in some characters as in the Japanese Rhinocypha above.
