[edit] Portuguese millipedes (Ommatoiulus moreletii)

Base on thi source http://www.agric.wa.gov.au/pls/portal30/docs/FOLDER/IKMP/PW/INS/GN2003_002.PDF. I'm havent found aby articles would someone know where into this family they actually fit, so I can link into and possibly expand. thanks Gnangarra 13:06, 31 December 2006 (UTC)

A quick web search for the scientific name gives "Ommatoiulus moreletii (Lucas, 1860) (Diplopoda: Julidae)" (see wikispecies:Julidae). --Stemonitis 18:48, 31 December 2006 (UTC)
Thanks for the wikispecies link, I didnt think of checking there. BTW article shortly Gnangarra 00:53, 1 January 2007 (UTC)

[edit] Confusion regarding subphylum classification

Ive been poking around wikipedia regarding centipedes and particular house centipedes and im a bit confused. It seems like there must be an error somewhere, but I have no idea where the error is. The house centipede article lists the subphylum as Uniramia, stating it is a variety of centipede. In the Uniramia article it states the the subphylum contains hexapods and myriapods, including centipedes. However the centipede article lists the subphylum as myriapod with no mention of Uniramia as the subphylum at all. So im lest confused, what is the real subphylum of centipedes including the house centipede, myriapod or Uniramia, and is myriapod really a subcategory of Uniramia at all, or are they both subphylums. I'm completely confused, and thing this is a major mistake that might need fixing. Debeo Morium 07:49, 26 July 2007 (UTC)

I just noticed the same thing. I'm in my college class right now and I decided to look it up. My professor says that the subphylum is Uniramia.--FUNKAMATIC (talk) 15:05, 10 April 2008 (UTC)
I guess that the Uniramia is an old subphylum that has since been replaced by the Myriapoda. If the house centipede article lists their subphylum as Uniramia it should probably be changed.--FUNKAMATIC (talk) 15:20, 10 April 2008 (UTC)

I wouldn't call this a "major mistake"; it's just a difference in classification. The different subphyla reflect conflicting theories of how major groups of arthropods are related.

1. The Uniramia hypothesis originally held that arthropods arose from several different ancestors (are polyphyletic), and uniramians were held to comprise myriapods, hexapods (insects and their kin), and even velvet worms. Today it's generally agreed that arthropods had a single origin (they're a clade, but a similar group called Atelocerata comprises myriapods and hexapods and excludes velvet worms, which aren't arthropods in this sense. If you're going to assign Uniramia or Atelocerata the (arbitrary) rank of subphylum, then I suppose you could call Myriapoda an infraphylum or superclass within that subphylum.

But there are other hypotheses:

2. Myriapods are the sister taxon to a clade including hexapods and crustaceans (together called Tetraconata or Pancrustacea. Together, they all form a clade called Mandibulata.

3. Myriapods are the sister taxon to chelicerates, and together they form a clade called Paradoxopoda or Myriochelata.

Indeed, the major groups of arthropods have been classified together in almost every combination, and a solid resolution doesn't seem to be imminent. Because of this uncertainty, the Wikipedia page on arthropods takes what seems to me a reasonably cautious approach of treating chelicerates, myriapods, crustaceans, hexapods, and the extinct trilobites as five separate subphyla. This isn't perfect either, because the monophyly of each of these groups has been questioned, but it seems like a good approach until things settle out. - Cheers, Cephal-odd (talk) 22:30, 25 May 2008 (UTC)

[edit] How many species?

This article lists both that there are 12 000 species and 13 000 species of myriapods. Obviously, these statements can not both be correct.--Gunnar Mikalsen Kvifte (talk) 17:01, 25 May 2008 (UTC)
