[Syrphidae] Timon-David Collection

[Gabriel Neve]

Dear Colleagues,

I am pleased to announce the publication on-line of our paper on the 
Timon-David collection of Syrphidae hosted at the Natural History Museum 
of Marseille. In due course, the paper will hopefully appear in 
Biodiversity Data Journal.

Hoverflies of the Timon-David collection (Diptera, Syrphidae)

Abstract :

Hoverflies are among the most important insect pollinators and there is 
documented evidence of a recent decline in their populations. To trace 
the past distributions of hoverfly species, verified records of 
historical collections are essential.

Here we provide data on 1071 specimens of hoverflies collected or 
received by Jean Timon-David and hosted at the Marseille Natural History 
Museum, France. Most of the specimens were collected by Timon-David 
himself and come from south-eastern France, mainly from the departments 
of Bouches-du-Rhône, Var and Hautes-Alpes. Most of these specimens were 
checked for the accuracy of their identification according to the latest 
identification keys. This resulted in 85 additions to the known fauna of 
the French departments, mostly for Var and Bouches-du-Rhône. The 
taxonomy of all specimens was checked against the latest available 
checklists, and updated names added whenever necessary. Specimens 
received from entomologists working in other continents (Brazil, USA, 
Colombia, Morocco, ...)  may also be valuable, as these are historic 
testimonies of the fauna of their own respective regions of origin, and 
may therefore also be used as reference material. One paratype specimen 
from Australia is present in the collection. The holotype of /Cheilosia 
vangaveri/ Timon-David, 1937 is absent from the collection and should be 
considered as lost. All but two of the specimens with locality labels 
had their geographical coordinates of origin added in the data set.

The data set is already accessible on-line at :

Best wishes,
