Hi Beth, to identify most species of termites from photos, good images of soldiers are needed. Soldiers have a larger head capsule and prominent jaws or pointed 'gluegun' snouts. (Exceptions are the two local mound-building species of termites, but there would be at least 30 other species locally).
Thanks Beth, it does help quite a bit. I suspect it is Porotermes adamsoni but cant rule out another group for sure. If you can use the original of the last photo to make an enlargement of the soldier, that might help. And were the soldiers unusually long for termites, i.e. 10mm? And did they have flattened heads?
