Ok.....I think the western gambusia are probably imported to that area where melanistic female eastern existed, its how they become melanistic in the first place.
And Brooklamprey, let it go and take your fighting words with you in another forums.

Sorry, I just like to whooped up at some things...ok I think Innes gambusia are not species but any gambusia that's melanistic in both sexes. There are no wild Innes gambusia and melanistic female eastern are very rare in nature but common in aquarium hobby. I just like all of fish species no matter if its exotic or native or hybrid.
Jamjam, try contracting Gambusia through PM and he will tell you.

From reading some of the material available on-line, the marbling/melanistic patterns come from holbrooki in which the males are heterogametic, and apparently the trick with the "Innes Gambusia" is to move that holbrooki Y chromosome into affinis, in which the females are heterogametic. By this line of evidence the melanistic trait is Y-linked, and Michael Ronayne has a hybrid line going that is 96.75% affinis but with the holbrooki Y chromosome. I still haven't found who named this strain after Innes, or exactly why, if such a why exists. So the long and short of all of the genetics here is that the Innes strain is a cultivar (to use the botanical term), hardly unique within commercially available livebearers.
Where did you find this specific info...I think I'm google challenged today..Likely in front of my face but I can't seem to find it.
I'm actually kind of interested in getting to the bottom of this fish and just where it came from..I personally work with a number of Gambusia species and populations. I have much more interest in learning my self.Hey, don't include me in this fight! I'm here to learn not to be in any fights.
Butch word of advice..Don't talk to an Administrator of a site like this...your not going to change my mind on a poorly chosen common name so I really would not get so defensive.And Brooklamprey, let it go and take your fighting words with you in another forums.

I believe this is what Mr. Ronayne posted on the ALA forums.

What types of Gambusia do you work with?

At this time I just have a bunch of Affinis and Holbrooki from various native and introduced localities.
I was working with G.marshi, G. luma, G. nicaraguensis, G. punctata, G. puncticulata, G. rhizophorae and G. krumholzi.
Krumholzi and luma I have to say where my favorites. As soon as I have more time to deal with more tanks I may start keeping a bunch of these Mexican, Caribbean and Central American species again...I would really like to get a colony of Clarkhubbsi but I'm not holding my breath on that.
Gambusia really are cool little fish...What is unfortunate is they do not have the best reputation..While much of the bad rep is well deserved they really are an interesting aquarium fish and some are actually very pretty fish.

If I could, I would. But I don't know how.
Find a members post and click on their name. You will have a drop down menu. Select 'send message'. Type the title of your message and the contents, then click 'send message' at the bottom. It's like email but within the forum only.
If you can't find a post of the person you're looking for, go to 'members' at the top right and search by typing in a portion of their name in the upper left search box. You can then click on the name and follow directions above.
If you're still having trouble post here and I'll help you via PM.

Just to fan the flames of this debate I would direct everyone to the Innes book (mine is dated 1956). In it he states that BOTH the western and eastern G. affinis have both black and/or spotted females and males occasionally. Maybe if nothing else this is where the Innes name came from

That's an impressive list Brooklamprey. Did you collect these yourself? I wish I could get my hands on some of those. Especially G. punctata and G. puncticulata. The only 'exotic' I have is G. Vittata. I envy you.
I wish I was traveled enough to collect most of those
Most where collected through trades or at auction with other ALA members. I collected most of the Affinis and Holbrooki in my current collection..

1958? That's old and many things have changed since. We need very strong proof that melanistic western gambusia existed.
I don't evny brooklamprey.
Through I'm interested in that population of melanistic eastern. And of course margrove/eastern hybrids.
Ok it need new name for Innes gambusia before we killing each other. Any ideas?

Brooklampry, I have caught both black and speckled males and females Gambusia here in Savannah in the drainage ditches. I'm going after some more this weekend (I fed them all to my Frontosas). Just for my own info are you saying that G. affinis and G. holbrooki are separate species or are they actually named G. affinis holbrooki. Or are the black fish the dreaded "H" word. It would be interesting to know seeing as they were described by Innes (NOT an actually scientific book) ...Jim

I'm looking forward to the convention this year in San Antonio. I hope to find some of the aforementioned fish there.
I collect Affinis locally (though I have no idea if they are native to this area or introduced). I have collected many over a long period of time and have never seen a spotted specimen. I have caught some that had a more peach like coloration (not the best description I know but that's the only color that comes to mind). I also have some that I can't identify but I believe are largespring gambusia (G. Geiseri). Do you (or anyone reading this) have an image of the G. Geiseri you could post? I tried taking pictures of them but I really suck at it. And I couldn't find any pictures online.
