The Odonata collection deposited at the Museum of Comparative Zoology (MCZ) includes specimens of 634 taxa labeled as types. Fifteen of these have been incorrectly labeled as types (pseudotypes) and eight are apparently lost, leaving a total of 611 types currently deposited at MCZ. From these, 489 represent primary namebearing types (syntype/s, holotype, lectotype and neotype), 21 are probable primary types, and 101 are secondary types (paratype/s, paralectotype/s).
A checklist of 49 damselfly species from 12 families (Odonata: Zygoptera) recorded from Kon Ka Kinh National Park is provided. A first description of the female Protosticta socculus Phan & Kompier, 2016, is given. Burmargiolestes cf. laidlawi Lieftinck, 1960 and three apparently new species, two Coeliccia and one Protosticta species, are recorded, all of which are to be described in the future.
Phnom Tumpor is a scarcely accessible basalt table mountain in the Cardamom Mts. in Pursat Province of Cambodia. On top surface it bears tall evergreen forest (ca 1100 m a.s.l.), concealing a slow rivulet, O'Gran, being a chain of deep pools. It was examined odonatologically on March 1418th, 2019. Six common species were recorded in dry and burnt scrub on the Phnom Tumpor slopes and ten on the forested upper surface at O'Gran, among them Polycanthagyna erythromelas (Selys, 1891) and Macromia sp. cf. pinratani Asahina, 1987 for the first time in Cambodia. The peculiarities of the males of Coeliccia kazukoae Asahina, 1984 from Phnom Tumpor and the problem of distinguishing females of M. pinratani and M. moorei are discussed.
Survey in three protected areas of Chhattisgarh reveals the presence of 50 species of Odonata belonging to 34 genera and 9 families. Specimens were sampled from different lotic and lentic ecosystems. 17 species were exclusively found in or around running water. Larvae or exuviae of 23 species were found and photographed. Habitat availability, larval abundance, species composition and phenology are discussed.
In May 2018, 34 dragonfly species were recorded on Wolin (21), Usedom (30) and the adjacent mainland (21). The most frequent spring species in the area were Coenagrion puella, Libellula quadrimaculata, C. pulchellum, Ischnura elegans, Erythromma najas, Brachytron pratense and Cordulia aenea. C. lunulatum and Calopteryx virgo were recorded for the first time on Usedom, while Anax parthenope, Libellula fulva and Leucorrhinia caudalis were recorded for the first time on Wolin. The occurrence of Coenagrion armatum, which had been recorded in 2016 on Usedom, could not be confirmed.
The quantitative results of the survey are given for different types of water bodies (ditches, pools, ponds, lakes, bog lakes). The average number of species per water body was highest in bog lakes (7.5) and lowest (3.4) in temporary pools. In comparison to older studies from the area, the flight season started 13.7 days earlier in 2018 than in years documented prior to 1989. This might be explained by climatic changes. The species composition, however, has remained rather stable – at least on Usedom and the mainland. On Wolin, climatic factors as well as habitat loss and transformation have led to a species composition that is different from the one recorded in the first half of the 1970s.
New data on Odonata of the Preah Sihanouk Province of Cambodia obtained in March 2017 and November 2018 are presented. The presence of Onychargia atrocyana Selys, 1865 in Cambodia is confirmed. Twentyone species are added to the known fauna of the Kbal Chhay Waterfall environs, 19 species to that of Ream Peninsula and 4 to that of Koh Rong Island. The total number of species registered for Kampong Saom Peninsula amounts to 74. The presented data are rather of historical importance since most of the remaining forest has been quickly and irreversibly logged a few months ago. The validity of Gynacantha demeter Ris, 1911 as a species distinct from G. dohrnii Krüger, 1899 is doubted.
Globally urban wetlands are under high anthropogenic pressure of degradation. Urban wetlands are hotspots for species losses and rapid turnover in species assemblages. Therefore, studying such wetlands may provide an estimate of the pace of local extinction, concerning wetlanddependent species such as odonates. We undertook a study to document odonate species across a tropical urbanization gradient. We sampled six localities across the gradient across the Mula River that flows through the Pune City, India. We sampled adult odonates using a newly devised Halfcircle Point Count method from September 2016 to March 2017. We took multiple temporal replicates per site. We also sampled larvae across six sites once in November 2016. We measured site characteristics such as canopy cover, solid waste, and water turbidity to understand the level of disturbance at each site. We recorded 41 odonates, six species (primarily Gomphidae members) exclusively from the larval sampling. We did not find the localization of species in a particular site across the urbanization gradient, possibly because we sampled a relatively short stretch of the river to capture the variation. Here, we update the Odonata list of Pune including data on larvae. We demonstrate that larval sampling complements Odonata surveys, especially in recording Gomphids.
We recommend future research to include a longer timespan and extensive sampling area.
The article presents new faunistic data on 33 Odonata species, based on the material collected by the author in 2012, 2016 and 2017 and a systematic research in 2018 throughout the Nakhichevan Autonomous Republic (AR). Onychogomphus assimilis (Schneider, 1845) is a new record for the fauna of Azerbaijan. Eight species were registered for the first time for the territory of Nakhichevan AR: Lestes virens Rambur, 1842, Coenagrion scitulum (Rambur, 1842), Aeshna mixta Latreille, 1805, Anaciaeschna isoceles (Müller, 1764), Anax parthenope (Selys, 1839), Sympetrum sanguineum (Müller, 1764), Crocothemis erythraea (Brullé, 1832), and Selysiothemis nigra (Vander Linden, 1825).
Another survey of Odonata on the Indonesian island of Belitung is reported. This survey was the second survey conducted in the Belitung area with International Dragonfly Fund support and was focused to Belitung Regency's outer islands. Seventy two species were recorded during the survey. Significant records from the surveyed islands include Amphicnemis kuiperi, Mortonagrion arthuri, Mortonagrion appendiculatum, Teinobasis ruficollis, Platylestes heterostylus, Pornothemis serrata, Pornothemis starrei and Tramea phaeoneura. Almost all the records are new to the small islands surveyed, except for Mendanau Island for which there were already records of four species. A checklist of the odonate fauna of the outer islands is given in an appendix.
Contribution to the Odonata fauna of the Society Islands, French Polynesia (Insecta: Odonata)
(2019)
Following field studies in 2018 the Odonata fauna of Society Islands, French Polynesia is reviewed and the validity of all records analysed. An updated species list is provided, bringing the number of breeding species recorded from this island group to ten.
Field studies targeted Hemicordulia Selys, 1870 specimens for inclusion in the revision of the Pacific representatives of the genus. Samples were taken mainly from Tahiti and Raiatea, with some additional specimens collected from Bora Bora and Huahine. Only the Society Islands endemic H. oceanica Selys, 1871 was encountered on all four islands, being recorded from Bora Bora for the first time. At least one new species of Hemicordulia has been reported from the high mountain areas of Tahiti (Jacq et al. 2009, 2014).
The present study also emphasises the need for a revision of Zygoptera records from the French Polynesia and the rest of the Pacific. Presently, about 25 endemic species provisionally assigned to Ischnura Charpentier, 1840 and Hivaagrion Hämäläinen & Marinov, 2014 are known from the Society, Austral and Marquesas island groups (R. Englund, J. Jacq, T. Ramage, D. Polhemus, per. comm.). Only seven of them have been described so far. Detailed morphological and molecular analyses will likely prove the separate generic status of some of the species presently included under Ischnura.
