The Ant With No Name
First of all is an article in the NY Times Science section which at least got the genus name of the ant correct.A Pest Without a Name...Plus the NY Times article provides a link to the urban entomology page about the ant at Texas A&M which has more pictures and the latest known information about the ant:Exotic Texas Ant Paratrechina sp. near pubensWhat's this near pubens stuff? In biology species names have a two parts usually derived from Latin or Greek. So the best we can do is assign this ant to a genus Paratrechina but the best we can say is that it is similar to another member of the genus Paratrechina pubens or the Carribbean crazy ant. This ant has a very similar biology and has gotten to be a problem in Florida.Having the correct name is not just a pedantic matter, because often creatures that look alike have very different biologies. http://creatures.ifas.ufl.edu/urban/ants/caribbean_crazy_ant.htmOf course evolution being a dynamic process where one species begins and ends can be difficult to decide and it may be in time that the Texas ant will end up being classified as P. pubens or maybe characterized by some sort of genetic marker as a sub population.
