• Part 1, Oleg E. Kosterin, page 1-11: Taxonomical notes on Indolestes Fraser, 1922 (Lestidae, Zygoptera). 1. Indolestes gracilis expressior ssp. nov. from eastern Cambodia Abstract: Indolestes gracilis expressior ssp. nov. is described by a male from Cambodia, Mondulkiri Province, the river upstream of Buu Sraa Waterfall 12°34’ N 107°25’ E. Another male presumably belonging to this subspecies was illustrated from southern Laos in literature. The new subspecies is characterised by more inflated apical part of the cercus than in earlier known subspecies and is thought to range in plateaux of eastern Cambodia ?and southern Laos, although very rare. Part 2, Oleg E. Kosterin and Roberto Poggi, page 13-20: Taxonomical notes on Indolestes Fraser, 1922 (Lestidae, Zygoptera). 2. Indolestes birmanus (Selys, 1891) is bona species Abstract: The holotype of Lestes birmana Selys, 1891 (currently Indolestes birmanus (Selys, 1891)), housed in Museo Civico di Storia Naturale di Genova, is examined and depicted for the first time. Its cerci are not attenuated apically, hence this taxon cannot be a subspecies of Indolestes gracilis (Hagen in Selys, 1862).
