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).

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.

A catalogue of 1257 persons commemorated in the scientific names of extant dragonflies (Odonata) is presented together with brief personal information on each entry, typically the full name and year of birth and death (in case of a deceased person). Each individual has a list of the available species, subspecies, genus or subgenus names erected in his or her honour. A total of 1928 available eponymous species-group and 54 genus-group names are listed. These figures include also synonyms and homonyms. It was calculated that of the ca 8400 available species-group names in extant Odonata, ca 23 % are eponyms. Of the 933 new species-group names introduced from 1 January 1995 to 10 March 2015, as many as 42.9 % are eponyms.

Records of larval rearing in the Gunung Mulu National Park, Sarawak, Malaysia carried out in 2014 are presented. In total, larvae of 27 species were collected. Larvae of eleven species (22 individuals) were successfully reared out, one individual is currently still being reared. An additional three species were collected right after emergence, with the adult still sitting on its exuvia. Most notable are the samples of Orthetrum borneense, Leptogomphus cf. pendleburyi, Coeliccia cf. nemoricola 1, Coeliccia cf. nemoricola 2, Heliocypha biseriata and Elattoneura analis whose final instar larvae are undescribed.

We compared Chatham Island endemic species Xanthocnemis tuanuii to its congenerics from the New Zealand South Island: X. zealandica (newly collected specimens)and X. sinclairi (type specimens plus newly collected material). Two independent tests were performed –geometric morphometrics and molecular. Both analyses were consistent in supporting the status of X. tuanuiias a good species. Species differed statistically in the following morphological traits: head (dorsal view), male appendages (dorsal, lateral, posterior and ventral views), thorax (dorsal view), and penis (dorsal and lateral view). In addition to the original diagnostic features (mainly shape of the male superior appendages), a new morphological character is suggested here which reliably distinguishes the species based on the shape of the inferior appendages. There was no statistical support for the species status of X. sinclairi. The only feature re-ported as diagnostic (lower lobe of male superior appendages) was found to be variable and insufficient to warrant the previously proposed taxonomic rank for X. sinclairi. Molecular analysis of specimens showing identical appendages to the X. sinclairi holotype grouped them with X. zealandica specimens. Therefore X. sinclairi is synonymised with X. zealandica.

In the second half of February 2014, Odonata were searched for nine days on Bali andfour days on Lombok, the western Lesser Sundas, Indonesia. One species, Orthetrum chrysishas been for the first time recorded for Bali and six species, Nosostictaemphyla, Idionyx murcia, Brachydiplax chalybea, Agrionoptera insignis, Neurothemisramburii, Rhyothemis phyllishave been for the first time recorded for Lombok. The previous lit-erature concerning the two islands is analysed. To the moment, 55 Odonata species (3 unidentified) are known for Bali and 39 for Lombok, although the actual faunas of both islands are supposed to be equally rich, and further studies on Lombok are necessary. Odonata faunas of Bali and Lombok mirror each other in respect of high shares,29 and 23%, of Odonata species ranging to the west and east of the two islands, respectively. Efficiency of Lombok Strait as a biogeographical boundary was estimated as high as 0.6, so Wallace Line is of importance for Odonata. Some diagnostic characters of N. emphyla, N. ramburii, R. phyllis phyllisand Procordulia sambawanaand a taxo-nomical situation around Prodasineura autumnalisand P. humeralis, which is not justified biogeographically, are discussed. Short notes on habitats and assemblages of Odonata are added.

The results of two expeditions into the Ulu Baleh and Ulu Balui areas of the interior of Sarawak are presented, including data from forest that was pristine at the time of sampling but that was subsequently logged. A total of 74 species are recorded, notably including Coeliccia campioni, Coeliccia new species borneensis-group, Pericnemis spp., Heliogomphusblandulus, Leptogomphus pendleburyi, Chlorogomphus ?manauand Procordulia ?new species. A discussion of the results and potential differences in the odonate fauna of comparable logged and unlogged forest sites is given.
