Malaysia Jewel

[bistrobob85]

i obtained from a 813bp fragment of the gene COI (Cytochrome oxydase subunit I) presents a pairwise difference of 15.7% compared to the signature of Scolopendra subspinipes dehaani sampled in the province of Guangxi in southern China.

... So you mean that the usual difference in the genes would be of 2-3% for individuals within the same specie while you obtained a difference of 15.7% between your Malaysian centipede and the Dehaani? So the difference confirms that the malaysian specimen belonged to another specie? Please correct me if i'm wrong.

Malaesian Jevel could be another specie, closely related with S. subspinipes.

just a note from my side,

what picture are you guys basing those opinions on to determine its a Sc.subspinipes dehaani or not ?
i can't see the ventral side of the prefemurs on any of the pictures :?


PS: i've seen other Malaysian jewels and those had 2 spines on the ventral side of the prefemur,>>> so those were indeed no dehaani's, but you can't be sure on this one to my opinion, or Peter must post a ventral shot

You have reason! This pede have 5 spines like you said, the picture makes to me do a mistake. I have also pictures of this pede and have 5 spines... so subspinipes subspinipes? ( in the anatomical taxonomy field af course, until mikas unpublished work say the opposite)

Hi Carles,

I understand your doubts as I have finished my project about a month ago and that all data are still unpublished. You are right on a point: as far as the current published knowledge goes, this species of Scolopendra is more closely related to Scolopendra subspinipes than to any other species. It belongs to the same clade. However, on the type specimen I sampled from the state of Perak, Malaysia, the genetic signature I obtained from a 813bp fragment of the gene COI (Cytochrome oxydase subunit I) presents a pairwise difference of 15.7% compared to the signature of Scolopendra subspinipes dehaani sampled in the province of Guangxi in southern China. To give an idea of the genetic difference between both groups, it is commonly accepted that COI pairwise differences at species level is 3 to 7% among arthropods.

I understand also your need of "factual" information. You would certainly prefer taxonomic keys. What I mention here is nothing more than what I found during my researches and it will only be considered valid once published after peer review. If my data makes it that far, I will be glad to share them with you on this forum.

Cheers,

Mika

Hi Mika;

I liked that you understand me. I'm too a scientific man ( Health field not pure biologist like I supose you are) and I know the steps to follow to publish some new info. So you jumped it, and I couldn't believe it.

Now, I believe you ( give us the text when it will be published, please) but i have questions?

1. What was the population of the experiment? ( number of pedes used in the xperiment)

2. Are you alone, in this xperiment? What lab? Any University?

Cheers
Carles

Excellent and very pertinent questions, Carles .

I'm a bit into sciences too . I'm doing a certificate in Ecology to eventually go for a bachelor in Biology at the University of Québec in Montréal. I would REALLY enjoy reading your article too once it's done!!!!
