In 2014, 56 localities in four provinces of Lesser Himalaya in Pakistan were studied. A total of 28 species have been recorded. A female of the data deficient, threatened species Coeliccia vacca was recorded from Charhaan. The record of Drepanosticta carmichaeli is a new addition to the list of Odonata of Pakistan, and expand the range of this species further to the west. The taxonomical status of Ischnura aurora aurora – considered common in Pakistan, following baseline literature of Fraser (1933) – now turns out to be Ischnura aurora rubilio.

Damselflies recorded before the administrative partition of the Indian Subcontinent and now housed at National Insect Museum (NIM), Islamabad were reviewed and catalogued. This collection is the divided part of National PUSA Collection (NPC) transferred to the Pakistan during 1947. Data for this collection had never been available or published. A record of 104 taxa is reported herein. Few of the species were found double named, misidentified and not updated as per valid classification. Some of the specimens were found unidentified. All such issues were resolved by following regional literature.

The paper compiles records from four excursions to study the Odonata fauna of southern Guizhou, China. Between 2007 and 2010 in Xiaoqikong Park and Maolan National Nature Reserve, 104 taxa have been recorded. Some interesting species are discussed, compared with sibling taxa, and information on habitats and habits is given.
103
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.

Arising from a number of 2019 IUCN Red List assessments for a subset of Chinese Odonata, a series of corrections and taxonomic revisions were made to the World Odonata List. The rationale for these amendments is provided here. Paragomphus wuzhishanensis Liu, 1988 is shown to be a junior synonym of Paragomphus pardalinus Needham (1942). Epophthalmia kuani Jiang 1998 is synonymised as a junior synonym of Epophthalmia. elegans (Brauer, 1865) and Epophthalmia bannaensis Zha & Jiang, 2010 is treated as a junior synonym of Epophthalmia vittata Burmeister, 1839. Idionyx pseudovictor Xu, 2013 is shown to be junior synonym of Idionyx claudia Ris, 1912 and Sympetrum anomalum Needham, 1930 is treated as a junior synonym of Sympetrum maculatum Oguma, 1922.

This paper presents the faunistic results of three short field excursions conducted in spring and early summer of 2018 in Kosovo, considering dragonfly fauna one of the most understudied countries of Europe. This study presents first systematic dragonfly research in Kosovo. Within a total of 13 field days between end of April and end of June 2018, 60 sites were surveyed and 44 dragonfly species were found. Significant results include the first documented report of 15 species for Kosovo. New data on several other species with a broader European concern or generally rare on the West Balkan peninsula, i.e. Coenagrion ornatum, Anax ephippiger, Caliaeschna microstigma, Cordulegaster heros, C. bidentata, Somatochlora flavomaculata, and Sympetrum flaveolum, are also presented. The overview of all visited sites is included. Altogether, 47 dragonfly species are now reported for Kosovo.

In February 2012, Odonata were recorded and voucher specimens collected in Luzon, The Philippines. The focus of study was set on localities near Dinapigue and San Mariano (Isabela Province), sites in Casiguran (Aurora Province) and on Polillo Island (Quezon Province). 60 Odonata species were recorded. Three are new to science and have been formally to be described. Four species were recorded for the first time in Luzon. Amphicnemis furcata and Diplacodes nebulosa were rediscovered after several decades since they were last documented from Luzon.

The paper presents new odonatological data from the formerly unstudied islands Patnanungan and Jomalig as well from the northeastern part of Polillo, The Philippines. Four species are new for the PolilloIsland group, including one new taxon Anax parthenope julius – for The Philippines. Currently, 78 odonate taxa are known from the Polillogroup.

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.

Notes on a small Odonata collection from Tawi-Tawi, Sanga-Sanga and Jolo islands, Philippines
(2012)
Sulu region is among the least explored faunal region in the Philippine archipelago. Odonatologically, this region is poorly studied until recently. Presently a survey conducted in July 1 – 14, 2011 revealed ten new records in Tawi-Tawi raising the total number of Odonata to 54. Three new species records were made for Sanga-Sanga raising the known number in that island to 34. Three species were recorded for the first time in Jolo raising the total number to 18. One new species of damselfly was found and several questionable and possible new species of dragonflies were documented.

The Odonata fauna of Balabac Island, Philippines was studied in March 2013. A total of 41 species under 33 genera were recorded. Twenty-eight species were recorded for the first time in the island. One genus – Mortonagrion was recorded for the first time in the Philippines. Mortonagrion astamii spec. nov. and Prodasineura poncei spec. nov. are new to science and are described. Three previously recorded species remained elusive and not seen during the survey.
59
Odonata survey was conducted in Talaingod, Davao del Norte, Mindanao Island. Four major sites were explored in Barangay Santo Niño from December 26 – 30, 2012. Thirty five species under eleven families including one new species were found representing the first odonatological record in the province of Davao del Norte. Three species need further study while Orthetrum glaucum represents a new record for the island of Mindanao. Coeliccia exoleta population, a vulnerable species in the IUCN Red List of Threatened Species, was found.

Balut and Sarangani islands are two small landmasses situated off the coast of Davao Occidental, Mindanao Island. Despite recent increase on odonatological data from various islands in the Philippines, these two remote islands have never been explored. Hence, a short survey was conducted on first week of April and November 7 – November 14, 2010 on all freshwater systems in these two islands. Twenty-five species under seven families and 21 genera were found representing the first Odonata record for the two islands.
34
Odonata were recorded and voucher specimens were collected between August 3- 13 and August 16-20, 2011. This account lists 51 species of Odonata for both islands, 47 species in Siargao and 24 species in Bucas Grande. Thirty seven species are new island records for Siargao Island while the 24 species recorded in Bucas Grande represent the first island records. Three species are new to science, and two of which (Drepanosticta schorri n. sp., Pseudagrion schieli n. sp.) are described in the present paper. Four species previously listed (Hämäläinen & Müller, 1997) remained elusive during the present survey.

Odonata fauna of Diomabok Lake and its surroundings, Davao Oriental, Mindanao Island, Philippines
(2011)
During three visits in October and December 2010 and May 2011, a total of 56 Odonata species was recorded. All species reported here represent first Odonata records in the area. The most noteworthy discoveries were one novelty (Hydrobasileus vittatus) to the Philippine fauna and two first records (Tetracanthagyna brunnea and Aethriamanta gracilis) from Mindanao Island. Seven species represent either new species to science or potentially new species; one Drepanosticta and one Amphicnemis are new to science, and another Drepanosticta, Amphicnemis, Pseudagrion, Gomphidia and Urothemis are potentially new to science.

Polillo is a small group of island (27 islands in total) east of central Luzon (Figure 1). It is made up of four main island viz. Polillo I, Patnanungan I, Jomalig I and Palasan I and several islets. This island group has relatively flat to gentle sloping terrain and the highest point is only 300 m asl (Mt. Maluhod) in Polillo Island (ca 700 km²) which is the largest in the group and the third largest island in greater Luzon biogeographic region.

Polillo Island is the largest among the Polillo group of islands. It is the third (ca 700sq km) largest island of the Luzon biogeographic region. The island lies in central eastern Luzon, at the western edge of Pacific Ocean and has a seasonal climate with distinct dry and wet season. The island is biologically rich with several insular species or subspecies (McGregor, 1910; Robinson, 1911; Manuel, 1957). The recent Odonata survey revealed the rich Odonata fauna of the island (Villanueva, 2010). This paper provides an update on the known Odonata based on recent fieldwork in 2010.
