A new species of the genus Teinobasis Kirby is described from the Muller Range in Western Province, Papua New Guinea. Its male is distinguished from all other Teinobasis species by having a pale labrum, an extensively bright orange thorax, and ventrally bowed superior anal appendages that are markedly shorter than the plump, apically rounded inferiors. Characters of the male are illustrated, and the affinities of the new species are discussed.
Two new species of damselflies are described from central Halmahera in North Maluku Province, Indonesia. They are Drepanosticta pararudicula sp. nov. (Holotype MZB. ODON. 19257) and Nososticta halmahera sp. nov. (Holotype MZB. ODON. 19265). The two species are most similar to the Moluccan taxa D. rudicula and N. moluccensis respectively and their descriptions bring the total number of Drepanosticta species known from Halmahera to five and of Nososticta to two.
An odonatological survey, based on sighting and photographic documenting, was conducted in Palawan and in Cuyo Island. Ten species were found in Cuyo Island raising the number of known species from five to eleven. There are six additions to the Cuyo Island fauna: Agriocnemis f. femina, Ischnura senegalensis, Pseudagrion microcephalum, Brachydiplax c. chalybea, Neurothemis fluctuans and Neurothemis t. terminata. The occurrence of Coeliccia boettcheri, known from Cuyo, but not recorded during this survey, is discussed in some detail. Forty species were recorded in Palawan. Four new additions to the Palawan fauna were recorded: Lestes p. praemorsus, Pseudagrion microcephalum, Xiphiagrion cyanomelas, and Anax guttatus. Neurobasis daviesi, a rare calopterygid damselfly endemic in Palawan, was encountered at the northern side of Cleopatra Needle during the survey.
A catalogue of 1290 persons commemorated in the scientific names of extant dragonflies (Odonata) is presented together with brief biographical information for each entry, typically the full name and year of birth and death (in case of a deceased person). For each individual a list is given of all available species, subspecies, genus or subgenus names erected in his or her honour. In total 2021 available names which qualify as eponyms are listed. These comprise 1966 species-group and 55 genus-group names including synonyms and homonyms. It is calculated that of the ca 8550 available species-group names in extant Odonata, ca 23 % are eponyms. Of the 1065 new species-group names introduced between 1 January 1995 and 31 December 2015, 435 (40.8 %) are eponyms.
Distribution data of dragonflies and damselflies from western Bhutan collected during a trip from 10 October 2015 to 22 October 2015 are presented. In total 53 species were recorded of which eleven are new to the country (Aciagrion pallidum, Anisopleura lestoides, Megalestes irma, Gynacantha incisura, Gynacantha khasiaca, Gynacanthaeschna sikkima, Lamelligomphus risi, Somatochlora daviesi, Crocothemis erythraea, Sympetrum fonscolombii, Tholymis tillarga). Another three species, one Megalestes and two Cephalaeschna, were not identified to species level but are also addition to the list of species recorded from Bhutan.
Specimens of Neurothemis disparilis Kirby, 1889, N. fluctuans (Fabricius, 1793), N. fulvia (Drury, 1773), N. ramburii (Brauer, 1866), N. stigmatizans (Fabricius, 1775) and N. terminata Ris, 1911, including their subspecies, were studied with the main focus on the morphology of the vesica spermalis, wing maculation, wing venation, abdominal markings and vulvar scales. The results were compared with species descriptions and directly with type specimens where possible. The vesica spermalis, especially the medial process, is useful at least in separating species groups and supports the traditional differentiation methods using wing maculation and venation. The use of other characters in accessing specific status, coupled with known distribution patterns, is discussed. The following taxonomic changes are proposed: Neurothemis manadensis (Boisduval, 1835) stat. nov., Neurothemis papuensis (Lieftinck, 1942) stat. nov. and Neurothemis taiwanensis sp. nov. is described (27.5.1998, Kenting, Pingtung County/Taiwan, L. M. Juang leg.; holotype is deposited at Taiwan Forestry Research Institute, Taipeh, Taiwan). The type of Polyneura palliata Rambur, 1842 was rediscovered at MNHN and designated as lectotype; a lectotype for Neurothemis nicobarica Brauer, 1867 housed at NHMW is designated. The holotype of Neurothemis incerta Brauer, 1867 was rediscovered and synonymized with N. ramburii.
Between 2009 and 2016, a total of 174 Odonata species (Tab. 1) have been recorded in the Dehong Dai and Jingpo Autonomous Prefecture, China. 21 of these species are new records for China, and additional 26 taxa have to be described as new to science. Brief comments on selected species refer to morphological characters, distribution and seasonality.

A survey of Odonata on the Indonesian island of Belitung is reported. The work of Belitung Biodiversity Observer on Odonata is briefly outlined. Sixty four species were recorded during the survey, including two new records for the island. A checklist of the known odonate fauna, consisting of 105 species, of the island is given in an appendix.

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).
