Discussion:Odonates
I noticed in the WOL what I assumed to be a date inconsistency, since the taxa attributed to Sjöstedt have two close dates: 1899 and 1900. However, the corresponding article can be found in a journal dated March 6, 1899, which is the correct date for the taxa concerned (Cover of the Monographie on the Odonates du Cameroun of March 8, 1899 : against).
- Coenagrion glaucum Sjöstedt, 1900 : Pseudagrion glaucum (Sjöstedt, 1900) → correct date : Coenagrion glaucum Sjöstedt, 1899 : Pseudagrion glaucum (Sjöstedt, 1899)
- Hylaeschna Sjöstedt, 1899 [correct date here] [obsolete genus] – Note : the date of Hylaeschna paludis Sjöstedt, 1899 [synonym of Phyllomacromia paula] is correct on the WOL.
- Libellago cameruniensis Sjöstedt, 1899 → correct name : Libellago camerunensis Sjöstedt, 1899, the date is correct on the WOL.
- Libellago glaucifrons Sjöstedt, 1900 → correct date : Libellago glaucifrons Sjöstedt, 1899 [synonym of Chlorocypha cyanifrons]
- Libellago grandis Sjöstedt, 1900 → correct date : Libellago grandis Sjöstedt, 1899 [synonym of Stenocypha gracilis : anteriority to be studied]
- Libellago neptunus Sjöstedt, 1900 : Chlorocypha neptunus (Sjöstedt, 1900) → correct date : Libellago neptunus Sjöstedt, 1899 : Chlorocypha neptunus (Sjöstedt, 1899)
- Phaon camerunensis Sjöstedt, 1900 → correct date : Phaon camerunensis Sjöstedt, 1899
- Pseudagrion flavipes Sjöstedt, 1900 → correct date : Pseudagrion flavipes Sjöstedt, 1899 [synonym of Pseudagrion hemicolon : anteriority to be studied]
- Tragogomphus Sjöstedt, 1900 → correct date : Tragogomphus Sjöstedt, 1899
- Tragogomphus aurivillii Sjöstedt, 1900 → correct date : Tragogomphus aurivillii Sjöstedt, 1899
- Trithemis violacea Sjöstedt, 1900 → correct date : Trithemis violacea Sjöstedt, 1899
- Umma fuscomarginis Sjöstedt, 1899 [synonym of Umma mesostigma]. This taxon is well dated to 1899 on the WOL.
Pidancet undertook a collection of dragonflies from the Besançon region of France, which has been deposited at the Musée de Poligny (Jura department, France) (David [2020]). Pidancet (1856) adds two taxonyms that seem to have escaped the authors. The photographs in the collection are in line with Pidancet’s (1856) description and account for the following “new” synonymies, for which I agree with Gwénaël David. As this collection is housed in a “rural” museum and contains two types that are new to science (typus), local naturalists are taking steps to safeguard it.
- Aeschna justi Pidancet, 1856 is a synonym of Aeshna juncea.
- Libellula bruandi Pidancet, 1856 is a synonym of Orthetrum brunneum.
Further research shows that Barbiche (1887) agrees with the second synonym. For the first one he wondered as Dommanget (1998) do too, but Martin (1888) with this synonymie, as ourself (G.David et C.Deliry, com.).
Notes : This little-known synonymy was proposed here on the basis of photo examination of the holotype (David [2020], C.Deliry, com. confirmed with G.David, in litt., September 2020). Aeschna justi presented by Pidancet (1856) proves to correspond in my opinion (com., 2020), shared by that of Gwénaël David (in litt.) to Aeshna juncea. The type is in a Franche-Comté collection at Poligny and I plan to work on it. Dommanget (1998) had already spotted this synonymy, but did not give it as certain. In addition, Boudot & al. (1998) quote Barbiche (1887), who thinks it could be correct, and Martin (1888), who considers the association to be correct. Barbiche (1887) points out that the justi is dedicated by Pidancet (1856) to his brother. The main authors of Catalogues sur les Odonates have not dealt with this taxonym. Dommanget (1998) says that the description of Aeshna justi resembles that of Aeshna juncea quite well, while pointing out that it is curious that Pidancet did not use this name, which was well known at the time (Note, however, that at the time the definition of Aeshna juncea was in fact not all that clear (com., February 18, 2025)). Dommanget (op. cit.) has not found an equivalent in catalogs, particularly Bridges' (1994). He proposes synonymy with [?]. This author does not know how best to associate Libellula bruandi with anything other than an Orthetrum, a correspondence not made by authors until now. Boudot & al. (1998) refine Dommanget's (1998) thinking by adding that Barbiche (1887) thinks that the description seems to come very close to Aeshna juncea and Martin (1888) says that it is a species “which can only be the juncea”. As for Libellula bruandi, Barbiche (1887 in Boudot & al. 1998) says it is Orthetrum brunneum. These conclusions are identical to ours, but have escaped the authors.
