Strumigenys thaxteri

Identification
Bolton (2000) - Known only from Trinidad (and now Guyana as well), this very distinctive species is closely related only to Strumigenys reticeps, from which it is easily separated by the characters listed under the latter. S. thaxteri has extremely heavily built mandibles, bearing numerous relatively small teeth, that are reminiscent of those seen in the Malesian leptothrix-group, but even more massively developed. These heavy mandibles, coupled with reticulate-rugulose cephalic sculpture, dense pilosity, and the species-group characters listed above, render thaxteri easily identifiable.
