A small collection of Odonata from Nuku Hiva Island, Marquesas Islands is presented. It adds Anax guttatus as a new species to this oceanic group. Hemicordulia sp. nov. is reported, but not described because the same species has been sampled before and is pending a formal description. A short taxonomic discussion on observed morphological similarity of male anal appendages in taxa presently assigned to Amorphostigma, Hivaagrion and Ischnura east of New Caledonia is provided. Important considerations for biogeography of the Pacific Odonata are discussed too.
Libellula virgo Linnaeus, 1758 auf Grönland : eine Neubewertung der Beobachtung von Fabricius (1780)
(2012)
The record of 'Libellula virgo' in south-western Greenland by O. Fabricius in the 1770ies is reassessed. It is inferred that the specimen was most probably a female Calopteryx maculata. Morphological characteristics presented by Fabricius are com-pared with those of similar species from continental North America that might have reached Greenland. Origin and transportation of the specimen by accidental wind drift are discussed in some detail.
Six Odonata species were collected during night light trapping on the Mambilla Pla-teau, Taraba State Nigeria. Being predominantly diurnal insects, odonates captured in light traps have always been considered as an anomaly. The new data initiated an extensive interrogation of all records on Odonata collected near artificial light sources.A total of 415 records (402 published and 13 new) are presented here with a sum-mary of previous discussions and new discussion points. The general conclusion is that odonates are mainly confused by, rather than attracted to the light. New ave-nues for further research in this field are suggested based on previous important stu-dies undertaken on Odonata morphology and physiology.
Boudot (2022) criticised in unusually harsh language with reference to 'Resolution 74 (26) on the Right of Reply of the Committee of Ministers of the Council of Europe (https://rm.coe.int/CoERMPublicCommonSearchServices/DisplayDCTMContent?documentId=09000016805048e1)' in an e-mail with attached word document dated 31st January 2022, local time Zerf: 15.45h a small and rather insignificant publication written by Nataly Snegovaya and myself, and demanded that his counter statement be published. In my function as the responsible editor of IDF Report I granted this wish. I t has to be noted that all we had done was insisting on retaining the record of Bartenef (1912a) which we are considering a proven record of Gomphus vulgatissimus....
Boudot et al. (2021) extirpated, without any discussion, G. vulgatissimus from the list of Azerbaijan Odonata, subsuming all records of this taxon under G. schneiderii. This is contradictory to the fact that G. vulgatissimus was documented for Azerbaijan by Bartenef (1912). We discuss the current knowledge of the two taxa G. vulgatissimus and G. schneiderii, document a new record of G. vulgatissimus for Azerbaijan, and map all known findings of the two taxa that have been reported to date as well as the potential distribution (search area) of G. vulgatissimus in northern Azerbaijan.
