Tetranematichthys wallacei instead of T. quadrifilis

[Marc van Arc]

Vari, RP & CJ Jr Ferraris, 2006. The catfish genus Tetranematichthys (Siluriformes: Auchenipteridae). Copeia 2006: 168â??180.
After reading the above article and specifically the remarks on Tetranematichthys wallacei (pages 176-177), I think it is justified to change the species name in the Cat-eLog from quadrifilis to wallacei.
Quote: "Given that T. wallacei occurs in areas that are centers for the collection and export of fishes for the aquarium trade (e.g. Manaus, Brazil; Iquitos, Peru) it is likely that many of the illustrated specimens identified as T. quadrifilis in popular articles dealing with aquarium fishes are instead misidentified samples of T. wallacei".
Apparently this new species is widely spread, whereas T. quadrifilis is only known from Rio Guaporé.

It seems this thread can be moved to Resolved as well.

To my great surprise,

Tetranematichthys wallacei

is not mentioned in the Checklist of Catfishes. That's particular, because Ferraris is the author of both papers. So what's happened? Just a mistake or something else?
Lee, what's your view?

Hi Marc and all who are following this thread.

An important part of the Checklist is Appendix 3 (pages 440 - 445) in that it covers taxonomic publications (arranged in alphabetical order by the author(s)) from 2006. These were, according to the author, issued "...after the cutoff date for this Checklist." Even electronic publishing can have lengthy time constraints.

Tetranematichthys wallacei is listed in this section on page 444. Also, and importantly, this species is listed in the lengthy index along with the proper page citation. The listing is there twice - under both the genus and the species name.

So I would suggest the following to anyone that is working towards getting Checklist material transferred to PC (or doing anything else with it for that matter): Read over Appendix 3 to get a familiarity with the catfish species described in 2006; and be sure to cross reference against the Index.

I will note here that the above suggestions are not foolproof. An example is the case of the recent revisionary work on the Lake Tanganyikan Synodontis. Appendix 3 does list the three new species that were described in this work (and these names are indexed)...but the removal of S. irsacae from synonomy with S. dhonti is not noted and it is still listed as a synonym (text and index). In all fairness to Ferraris, I will note that this is a minor complaint and the generally up-to-date nature of the Checklist is quite something.

No doubt some more speed bumps will occur in transitioning material from the Checklist to PC. But, following the above suggestions might help a bit.

Thanks for the suggestion, Lee. I only checked the Auchenipteridae part on the assumption that a "2006 species" would be included in a 2007 publication. Which turned out to be a wrong assumption, as you pointed out.

It's 600 pages or so, so I guess we can cut them some slack. Useful interpretation of the data, what I would say is that the check list is useful for pointing out stuff that needs investigated but not, necessarily, changed.
