Re: Paralithoxus cf. raso

Hi, the location is wrong for P. raso and also for L 435 (=LDA066), both froms originate from Amapa, Brazil. The pictures are showing a form that is IMHO certainly something different and nearly for sure it also did not come from Guyana. If you continue to use the page for L 435 you should update th...

Paralithoxus cf. raso

Hi, the pictures on the species page of Paralithoxus cf. raso do not show P. raso and also not L 435 (which might be identical with P. raso ). The colouration is quite off, both species/forms have spots that are approximately the size of the orbital diameter. Furthermore P. raso has significantly lo...

Pictures for your data base

Hi, some more Suriname pictures from families I'm not too familiar with, so better double check before uploading (if you want to use them on the species pages)... Most IDs should be correct. https://www.l-welse.com/gallery/files/3/9/9/8/centromochlus_punctatus_4053.jpg Centromochlus punctatus , Tapa...

Re: Ancistrus temminckii species page

Hi, yes, also to my experience Haakon is very knowledgeable and I guess he knew where the fish came from. I meant both, close-looking as well as geographically close as this is near to the Surinamese border. Oh, the ones from Yann are all from the same place, interesting. The ones I caught there had...

Ancistrus temminckii species page

Hi, the first picture seems to be ok, but without knowing the origin it is difficult to be sure in this genus. All the other pictures look to me like Ancistrus forms from French Guyana that are not identical to Ancistrus temminckii . https://www.l-welse.com/gallery/files/3/9/9/8/ancistrus_temminckii...

Paralithoxus planquettei species page

Hi, the first picture is no Paralithoxus planquettei , do you know the catching location ? In the Lithoxini revision of Lujan et al. table 2: "white spots on body: absent", see also here: Paralithoxus planquettei how they do look like. The pictures from Yann are unidentifiable. Cheers,

Corydoras filamentosus & CW143

Hi, Corydoras filamentosus belongs to acutus group, lineage 1. Similar story as with C. spilurus , the tissue sample used within the framework of the phylogeny of Alexandrou et al. 2010 belonged to the sympatric CW143 which belongs to lineage 8. I have discussed this with Raphael Covain and he only ...

Corydora spilurus

Hi, this species belongs to acutus group, lineage 1. In the phylogeny of Alexandrou et al. 2010 the tissue samples used belonged to CW138 and not to C. spilurus , that's why this species ended up in the wrong lineage. I have written an article on this topic in the BSSW report 3-2017 "Über die I...

Re: Corydoras(ln9) sp. (Cw063)?

Hi, do you have any information from where those were imported, together with the C. similis ? I can definitely confirm C. similis and for the others CW063 could be an option. However, the specimen on the original picture has an even smaller caudal spot that is more elongated and a much more pronoun...

Re: Corydoras (ln5) id

Hi, I would tentatively agree with CW029. I have not kept those myself, so I only know pictures of adult specimen and not too much about variability etc. However, the dark broad stripe going from the eye towards the dorsal fin spine insertion seems to me a good diagnostic feature of this form which ...

Hypostomus commersoni

Hi,

pictures 6-9 on the species page are in fact Hypostomus spiniger. It's rather outside distribution range for H. commersoni and the last picture with the adult is without any doubt not H. commersoni.

Hypostomus albopunctatus

Hi,

on the species page the first 6 pictures are not H. albopunctatus (dorsal spine much too long).
Picture 7 is difficult to judge, picture 8 looks ok.

Hypostomus plecostomus

Hi, there some quite doubtful pictures in your data base. As there are lots of similar species from various locations that have been considered to belong to this species and also the populations in Suriname show quite a high variability in pattern it's difficult to identify them with pictures alone....
