Young Worker Ant Posts: 34 12/19/2007 4:39 PM Young Worker Ant	They are also involved in many seed dispersal processes. I took pictures of this for the R. metallica complex and R. violacea www4.ncsu.edu/~bsguenar/P...llica.html www4.ncsu.edu/~bsguenar/P...lacea.html For the distribution in Indonesia, I think it is just on the Iran Jawa part on the New Guinea island.

Henchant Posts: 1983 12/19/2007 5:03 PM Doc.	Those are some nice shots, Benoit. I especially like the ones with the seed. The photos towards the bottom of the R. metallica page are actually a different species- I don't know which one. You can tell because the ant is more slender and the posterior corners of the head are less quadrate and more rounded.

Adult Worker Ant Posts: 284 12/20/2007 6:33 AM	+ Diagnosis: From Australian Ants: The forward sections of the frontal lobes and the antennal sockets are separated by the broadly rounded or triangular rearward extension of the clypeus. The leading edge of the pronotum on each side just above the front legs with a small angular tooth or spine. The node of the petiole has distinct front, top and rear faces. The tips of the tibiae of the hind legs each have either a single small, simple or comb-like (pectinate) spur, or two spurs, one large and comb-like (pectinate) and one small and simple (best viewed from the front). The claws on the hind legs have a tooth at about the middle of their inner surface. Posterior coxae unarmed above. Promesonotal suture complete.

Minor Worker Ant Posts: 167 12/20/2007 8:05 AM Doc.	@ Wasmannia auropunctata Hi Benoit, These are great pictures! I am preparing a lecture on relations between ants and plants, and I am sure I will use one of the pics with a Rhytidoponera carrying an acacia seed in the context of myrmecochory! People seeing such pics for the first time should fall in love with ants! @ Dr Ant: The pic of myrmecos: www.myrmecos.net/ants/RhyCfm2.html reminds me an experience I once had near Sydney. I turned a slab with a Rhytidoponera nest underneath. A seemingly dead Myrmecia (large, red, I guess M. gulosa) was lying in the galleries. I took the carcasse with my fingers, and got terribly stung! Not by the Rhytidoponera, though. And this was the most beautiful nest of a Rhytidoponera I ever saw in Australia, near Brisbane. rhytidoponeragreen.jpg Unfortunately its all but sharp, however, the bright green colour is correct. Merry Christmas to all, A. Buschinger

Young Worker Ant Posts: 45 12/20/2007 2:07 PM Young Worker Ant	Makes me wish I lived in Australia www.myrmecos.net/ants/RhyMet2.html<-(favourite pic) Also, it says under the first picture in the previous post that ants don't usually eat dead members of their own species, why is that?(I'm guessing it might have something to do with disease transmission). Are they more likely to eat a dead ant the less closely related the species is, or is it a black and white situation?

Posts: 5364 12/27/2007 12:14 PM Doc.	From the antbase page atbi.biosci.ohio-state.ed...r?id=1142, below are some references that provide much of what we know about the lives of Rhytidoponera species, especially the impressa group. (Use link above to get pdfs.) #3 discusses the unusual reproduction of some species, in which some colonies have a single, normal (originally winged) queen morph, and others have an individual (or more than one) of typical worker form that mates and acts as colony queen. These colonies are founded by individual queens and by colony division, respectively. The two types of reproductive females apparently never occur in the same colony, but can occur in the same species. Alates are produced by larger, mature colonies, and are predominantly male in the worker-reproductive colonies. Worker reproductives mate near their parent colony, while winged females fly away to "some distance" before mating. 1. Ward, P. S. 1980.
