The final stadium larva of Euphaea decorata Hagen in Selys is described and illustrated for the first time. The larva of E. decorata is typical of the genus and characterized by having a flat and long body with large saccoid caudal gills, seven pairs of lateral abdominal gills, two or three large and sharp spines in front of the ventral margin of the eyes, and tridentate palpal lobes of the prementum. The supposed larva of Rhipidolestes nectans is corrected to that of an unknown Euphaei-dae. Known Euphaea larvae are shown to be generally very similar, but an old report suggests that the Indian species E. dispar and E. fraseri may show sufficient differences to restore them to the genus Indophaea. © 2017 Magnolia Press.


The final stadium larva of Coeliccia mingxiensis Xu is described and illustrated. The female adult is also described for the first time. The larva can be easily separated from all known Coeliccia larvae by the following distinct morphological characters : (1) prementum longest in all known Coeliccia larvae; median lobe with 4 pairs of premental setae and palpal lobe with 6 palpal setae; (2) caudal gills shortest of all known Coeliccia larvae when compared with body length; median gill rounded at apex and lateral gill with a small median projection at apex. The female is similar to the male in many respects, differing chiefly in several respects as follows: the transverse yellow band on vertex of head broader and straighter than in male; antehumeral stripe on mesepisternum somewhat incurved basally, not forming a strong hook, which is present in male; distal abdomen with obviously different colour pattern; anal appendages brownish-black, shorter than S10; vulvar scales robust, brownish-yellow, projecting well beyond end of abdomen.

A new species of the genus Idionyx Hagen, I. pseudovictor sp. nov. from Fujian, China is described from the female, illustrated and diagnosed from its congeners. Description of the final stadium larva of the new species is also provided. The new species is closely similar to female I. victor. There are a series of relatively minor colour and pattern differences between these two female adults, as well as a series of obvious structural differences in larvae of these two species. The female adult of the new species can be separated from that of I. victor by the following characters: (1) labrum entirely yellow; (2) distal end of ventral synthorax entirely yellow; (3) abdominal S1-2 with complete middorsal yellow stripe;(4) valvula vulvae pointed triangularly, not projecting beyond apical border of 8th tergite. The larva of the new species can be separated from that of I. victor by the following characters:(1) body dark brown, covered with dense long hairs;(2) apical border of prementum with 10 spiniform setae on each side;(3) premental setae 5+3/5+3;(4) numerous fine bristles present on median lobe;(5) inner margin of palpal lobe with 6 large projections; and (6) movable hook long and acuminate.


The final stadium larva of Heliocypha perforata perforata is described and illustrated for the first time. It is characterized by having a row of filiform setae present laterally on distal half of prementum, 6-7 setae on the outer side of palpal lobe, very long lateral gills and distinct abdominal color pattern. The taxonomic characters of the larvae of the genus Heliocypha Fraser are discussed and summarized. Heliocypha larvae share a high similarity with Rhinocypha in general appearance and cannot be clearly distinguished from the latter in structure. Copyright © 2015 Magnolia Press.

The finnal stadium larva of Periaeschna zhangzhouensis Xu is described and illustrated for the first time.

A new species of the genus Periaeschna Martin, P. yazhenae sp. nov. from Fujian, China is described, illustrated and diagnosed from its congeners. Description of the final stadium larva of the new species is also provided. The new species is closely similar to P. zhangzhouensis Xu 2007 due to the high similarity of anal appendages, but is easy to separate from that species by the following characters: distal 1/4 of cercus narrowest and with truncated apex; abdominal segments 1-9 with simpler and less developed dorsal markings and with more complicated and more developed ventrolateral and ventral markings; and wings tinted with brownish-black at extreme base.

The final stadium larva of Philoganga vetusta Ris is described and illustrated in detail. The larva of supposed P. vetusta from Hong Kong is confirmed, and that of Philoganga sp. from Fujian can be determined to be P. robusta. The taxonomic characters and systematic status of the larvae of genus Philoganga are discussed and summarized. © 2016 Worldwide Dragonfly Association.


The larva is described and illustrated based on 2 specimens from Fujian province (China), and a comparison with Nihonogomphus lieftincki and Orientogomphus armatus larvae is provided. Judging from larval morphological characters, the genus Amphigomphus is closer to Orientogomphus than to Nihonogomphus.
