The final instar larva of the rare species Platycnemis phasmovolans Hämäläinen, 2003 is described and illustrated here for the first time, including a new distribution record from Vietnam. The larva of P. phasmovolans differs from that of congeneric species by distinct morphological features, including the presence of four setae on the palpal lobe of the labium, the presence of lateral spines on abdominal S5–9, and a long terminal filament on the caudal lamella. We also provide a key to species for the known larvae of the subfamily Platycnemidinae in the Sino-Japanese and Oriental regions.
