Leptolebias fractifasciatus Barra de Maricá

[hwchoy]

Au, this chap looks pretty washed. Is it still too young or it just needs some good food?

*********************************************************

This is actually a female Fundulosoma thierryi Accra Plains Gh 1/94 which I confused with the Leptolebias fractifasciatus.

OK. here's the right fish… but dorsal fin is slightly tattered and I'm not sure if it is looking in the pinkest of health.

Your "chap" looks like a little lady to my untrained eye... Do you have a picture of any little boys?

[hwchoy]

I was thinking that too but don't quite recall him passing me a girl. And I could have mixed up their ID since I got quite a few species together.

[TyroneGenade]

What species did you get? May be able to sort things out better if we knew the other options.

Here is a picture of a L. minimus female which is I guess is as close as we are to get to a female fractifasciatus. The fish are superficially similar. Huber's Killidata gives a male anal fin ray count of 18 and states that females have 2 to 3 less. The fish pictured has 16 rays so this confirms OKish. For the dorsal fin he gives 15 for males and again 2 or 3 less for females. The pictured fish has 12 (best I can tell).

I've forwarded a link to the picture to the Cynolebias list... maybe someone else can be more definative.

Au very kindly gave me the following:

• Simpsonichthys whitei var. albino Cabo Frio (pair)
• Fundulosoma thierryi var. Gh 1/94 Accra Plains (pair)
• Simpsonichthys trilineatus var. Brasilandia
• Simpsonichthys delucai
• Leptolebias fractifasciatus var. Barra de Marica

just need to confirm with Au that's all.

Hello

I received a private email from Lee van Hyfte who suggested the spotting represented an African annual more. The name F. thierryi was mentioned. I checked Huber's Killidata and indeed, theirryi has 15 anal rays and 11 dorsal rays which is very close to what we see. The blue shine also suggests a female theirryi. See here .

I think this may solve the mystery.

If you get a good shot of the delucai and other SAAs, would you mind sending me a copy for use in the SAA magazine the SAA study group is churning out?

Thanks

[hwchoy]

geez, now I really need to get to Au. If this is a female thierryi then WHERE IS that Leptolebias?

[hwchoy]

mystery solved! found the Leptolebias in the tank, was hiding somewhere all day!

Tyrone, you mean the 'Riv Nut' is here amongst us?

Lee, if you're reading this, welcome aboard. We've much to learn from you as well.

Thanks

sure, but the simps are real dodgy characters

[TyroneGenade]

Hello Ronnie

I'm afraid "The RivNut" is not among us best I can tell. I sent a link to the thread to the Cynolebias list and Lee had a look see and let me know privately his thoughts.

Any chance Heng Wah that you can place a smaller version of the picture back up and post the new one later just to that other visitors can have a look see and render their opinion?

Hi Choy,

Are you testing the knowledge of fellow hobbyists with you pictures?

Well, you're kind of a funny person. I'm afraid that you'll mix the females up and thus I pack the true pair in separate bags and yet you throw them into a same tank!

Anyway, things have being sort out eventually.

The picture posted is indeed a female Fundulosoma thierryi .

Let me get my webpage up again and post the picture of the Leptolebias fractifasciatus

[hwchoy]

only the thierryi comes as a pair (the whitei too but they're quite different from the funds ) so I wasn't worried about mixing up the females. only problem was after throwing in 4 fishes I could only find 3! Only later did I find the Lepto

Choy, we killie folk have a different way of seeing how fishes are named. The var. bit isn't quite used and as usual most population or location names are in parentheses after the species name. It would be wise to follow the method that has been used for quite a long time in the hobby. Though the ICZN?or IUCN? states that var. should be used, we are pretty different folk. Therefore, Lepto. fractifasciatus var. Barra de Marica is usually known better as Leptolebias fractifasciatus "Barra de Marica".

The Simp. delucai is known only from its type locality in the rio Urucuia drainage. The only population in the hobby (to the best of my knowledge), is listed as Simp. delucai "Urucuia".

[stormhawk]

Did a check and the swamp is usually known as restinga de Barra de Marica. The locality is close to a city called Maricá. Sometimes the location is also spelt as Barra de Maricá.

With regards to the earlier location given for the Simp. delucai, that is indeed the only known population in the hobby but I am not sure if Au's fish come from the same locality.

yes I know, I've been thinking about it. Since my pics would eventually end up on a "not-just" killies only site I tend to favour a consistent naming format. In fact I'm not sure "var." is an appropriate term, "pop." maybe better but hey that will confuse even more people

Maricá you say? OK will use the proper alphabet.

The Simp delucai I was not given a code by Au so it doesn't.

[CM Media]

The Simp delucai I was not given a code by Au so it doesn't.

As usual, when I got the fish from someone, the person did not label the population code. Also, at that point of time, we're still unable to confirm that it's the Simp. delucai.

My usual practice is I'll not append any code to the fish I got if the sender do not tag it even if the fish is only collected once.

agreed.

The term var. has been used in botanical applications, especially with cultivars of some house plants such as orchids and the like. Even among plants like the Tillandsia species, there's also man-made cultivars and hybrids. Hybrids are denoted as - Genus species x species.

The cultivars are denoted as Genus species var. xxxxxxx

When we use var. for aquarium fish it is somewhat telling us that these fish are aquarium-bred variants of the fish. Take for example the guppy. We have cobras, king snakes, etc. All these are exotic man-made varieties of the common guppy. Therefore we apply the var. tag to such animals. If I'm not wrong, there's also an aquarium form of Nothobranchius eggersi which was created by breeders in Hawaii to perfect the blue colouration from the Ruhoi? population. They happen to call their fish Notho. eggersi "Blue Hawaii". The var. tag here can apply to such a fish because they are by all means, man-made variants of a species.

Killies on the other hand, are collected from several spots and not just one, unless the ONLY collection has been from a single locality per species. Again, the use of the location code in parentheses is and has been a standard form for us to term our fishes by. That said, these are not man-made varieties, but rather natural geographic variants of each species. Take for example Aphyosemion (Kathetys) elberti. All of the locations look somewhat different, for example the N'douzem, which is a much bluish looking fish, and the Diang, which is a mix of red and yellow.

If its not too much work, just use the parentheses for the location code, and end the tag with the collection code when it comes to killies. :wink:

[hwchoy]

var. can apply to natural varieties too right? e.g. Sundadanio axelrodi var. red

anyway the idea was to not create a separate standard for killies since it would be meant for non killifolks to see. I'll see what the ichthylogoist suggest
