Two new subspecies of Hemicordulia tenera Lieftinck, 1930 (Corduliidae) from Cambodia and Thailand
(2015)
Hemicordulia tenera donnellyi ssp. nov. (holotype ♂: Chieng Mai Prov., Kunklang: highway 1009, Restaurant; 16°32.0’ N 98°31.3’ E, 1000 m, 22 v 1996, FSCA) and H. t. vikhrevi ssp. nov. (holotype ♂: Cambodia, Koh Kong Province, ~13 km ENE of Koh Kong, ‘Hemicordulia brook’, 11°39’55’’ N, 103°05’34’’ E, 315 m, 04 xii 2010, RMNH) are described from North Thailand and South-West Cambodia, respectively. The nominotypical H. tenera tenera Lieftinck, 1930 is distributed in the Malay Peninsula, Borneo, Java and Sumatra. Although these three subspecies are genetically very close, they are distinguishable by the relative length and shape of the caudal appendages.

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.

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).
