Map Update #5

Filed under: Database additions

Four months since I made the last update of the Ant Genera of the World website, and the less that can be told is that it has been a good time for the Ant Genera of the World database. 167 new records have been added concerning 87 genera! Almost a third of the known genera are concerned.

The new records allow to refine our predictions on the unknown distribution of some genera, and so the improvement of future predictions. As a result, 17 new interpolations have been added.

Most of the new records concern Honduras thanks to the work realized within the LLAMA project of Jack Longino, this year helped by Michael Branstetter who discovered two very interesting records among several others; Formica captured on the top of a mountain (this is the southern record of Formica for the New World); and the northern record for Paraponera (the bullet ant).

Lots of new data have been communicated to me for Brazil thanks to Rodrigo Feitosa who does an excellent job therel within the team of Roberto Brandao (who gave a very interesting talk at the IUSSI meeting). Thank you Rodrigo!

Other records came from various papers. One was especially important in this new update and focus on the ants of northern Mexico by Alatorre-Bracamontes and Vasquez-Bolano

During this period, at the beginning of August was the IUSSI meeting in Copenhagen. It was the occasion for me to present my work to many fellow myrmecologists, to see some friends and to develop new contacts. I had a fantastic time there and would like to thank all the people who visited my poster, and for their encouragements. It was great to hear about the website being useful and people to be eager to share new records! I am looking forward to see many of you and have more interesting discussions in the future.

At this point, this is my turn to share a few new records, but this time at a species level. I have found the rare and enigmatic Amblyopone trigognignatha (only collected one time in 1948 from one individual) two years ago during a photo session (confusing it with the more common A. pallipes), and recently the ant was identified from my pictures by Alex Wild. More info is available on this story is available on This summer I also collected ants in different places of North Carolina in order to improve our knowledge on the myrmecofauna of this state. I am glad to announce that I have collected (yes, I collected it this time) what I have identified as Hypoponera inexorata! Finally, very recently, we did some collecting in South Carolina, and we captured Discothyrea testacea, a new record for the state (I had no records of this genus for SC in the database). I also suspect this species to be present in Virginia as I collected populous nests of this species only a few miles of the border of this state, but on the NC side. So if you go in Virginia, collect some leaf litter and you’ll have some good chance to find it!

So take your hand shovel and hang your Winkler bags!
