Abstract:
The larvae of Macrothemis aurimaculata and M. inequiunguis ape described and illustrated. A redescription of M. celeno is also provided. Macrothemis aurimaculata can be separated from other species in the genus because it has reduced or vestigial dorsal protuberances on abdominal segments VII-IX. Macrothemis inequiunguis can be differentiated by the presence of 7 setae on the labial palp, in contrast to less than or equal to 6 in other species. Both species inhabit streams in areas with slow-moving water. Macrothemis celeno closely resembles hi. inacuta and M. pseudimitans. Some features to separate larvae of Macrothemis from its close relative Brechmorhoga are given. A key for identification of all the described larvae of Macrothemis is provided.
