Hi Steve – I agree completely.  B. maculisparsa needs to be evaluated.  We have not been able to get hold of a specimen to sequence, so it remains an unknown, but there is a good chance it is not the same as the hybrids.  Only one way to tell.  Any chance of getting a hold of one?  It is indeed close to the Sri Lanka beast.  Now we have two unknowns without DNA ;-)  Cheers – Gustav

Hi Gustav,

I fully agree with your point. Had Chamari just sent a photo of one specimen, I dare say that some would have replied back and written it off as a hybrid. But with so many, could they really be the result of hybridisation? From my eye, they look pretty similar (some almost identical) to those pictured as B. maculisparsa in the chapter by Feral and Cherbonnier (attached), although I am not saying that is the same species as Chamari has photographed in Sri Lanka. I suspect that there may be some sizeable populations in New Caledonia of what Cherbonnier and Feral named B. maculisparsa (I had seen it years ago in some numbers at deeper inshore sandy bottom habitats near Mont Dore, New Caledonia). Actually, I seem to recall that Sun had 'written that off' that species as a hybrid in an email some time ago because similar looking specimens in SE Asia came out as hybrids from the genetic work. We were mindful of that in the recent paper about the IUCN Red List findings, and you may have noted that Bohadschia maculisparsa is actually one of the Vulnerable species. I think that some of the aspidolisters may have found that strange and wondered why it was on the list. The reason was that, from all data that we had, it appears to have a very restricted distribution in a region heavily fished, and the IUCN had to accept it as a valid species because it was on WoRMS and had no publication that we were aware of had shown it to not be a valid species. Time may change that but, for the moment, it is one of the threatened species. Some great genetic work has been done on Bohadschia recently, but I have to agree generally with Chantal that there is more work to do!

Best wishes,

Hi Chamari,


I am just back from the field.  You sent images of this species earlier as well.  This is likely a new species of Bohadschia.  I have not seen it anywhere.  It does not look like the argus-vitiensis hybrid, and you would not expect an entire population to consist of hybrids (where are the parent species)?  Good chance this is an endemic species to your area.  Would have to study and sequence to know for sure of course.


Cheers - Gustav

Dear Professor Conand,

We have huge catches of Bohadschia spp in the northern part of Sri Lanka and I am sending few photographs of landings and processed product

Thanks Maria, but we have not B. argus in IO    I have looked at you paper.

Hi Chantal

this is the one Sven and I call 'spotty' - the hybrid with argus as one parent



Quoting Chantal Conand <[log in to unmask]>:

Hi Yves

Since I read the paper 2013 (thanks Franck), it looks funny to me also, as

there are no B. argus in the IO....meaning other hybridation ...

Bohadschia stories are not closed!!!

 Hi all

Same appeared to me... but a bit problematic as 'B maculisparsa' is not
supposed to be in the Indian Ocean. B. atra hybridizes too?

Cheers - Yves

Dear Chantal,

This looks like another example of whatSun, Alex and Gustav nominated as

a '...putative *argus-vitiensis* hybrid with *vitiensis* background
colour and ocellar spots similar to *argus*'. This is in their 2013 paper

in the Zoological Journal of the Linnean Society (Colour, confusion, and

Dear colleagues

I just received this photo (without sample nor spicules) from Mauritius, I
believe it is a Bohadschia, but which species please?
Best regards from Paris
