Are Cichlids in ordo Cichliformes?

Post by Bojan Dolenc » Thu Sep 20, 2012 3:23 am

In new eighth edition of Dr. Richard van der Laan’s huge ‘Freshwater Fish list’ (Free book download) I found this innovative taxonomy for freshwater fishes: Euteleosteomorpha – Acanthomorphata – Percomorphacea – Cichliformes?
Is this again some new sphere for cichlids? To date cichlids were in Perciformes (Labroidei) order. :?

Thank You, now I remember this recent study with new group: Ovalentaria, we discussed this yet here: viewtopic.php?f=17&t=14438
Therefore Cichliformes are the same group as Ovalentaria?

Stupid me, I found yet:
"8a clade: OVALENTARIA Smith & Near, 2012 (fishes with demersal, adhesive eggs){=“Cichliformes” + Mugiliformes + Atherinomorpha + Gobiesociformes}."

If the family Cichlidae would be promoted into an order - Cichlidiformes or an underorder , this would result in more levels to be used for groupes

Imagine the situation where we could have 3 families, 8 or more sub families (and thus no discussions who is right) and perhaps even forget about tibes and so on

Now we only need the biological evidence. Somebody willing to frams something? :lol:

Ovalentariae: sticky eggs
Our results suggest that this group can be divided into four subgroups (superorders), two of which already existed (Atherninomorphae and Mugilomorphae) and two that are new: (i) Cichlomorphae (Cichlidae plus Pholidichthyidae) and (ii) Blennimorphae (blennioids plus clingfishes, jawfishes and basslets). Many families in Ovalentariae, however, remain incertae sedis (e.g., Embiotocidae and Pseudochromidae). Two different studies have coined a name for this group; first Stiassnyiformes by Li et al.24 and, more recently, Ovalentaria by Wainwright et al.31 for their characteristic demersal, adhesive eggs with chorionic filaments (lost secondarily in some groups). An interesting implication of this phylogenetic hypothesis is that the pharyngeal jaw apparatus (pharyngognathy), present in many members of this clade (e.g., Cichlidae, Pomacentridae, Hemiramphidae), has evolved multiple times in percomorphs31. We refer the reader to Wainwright et al.31 for additional discussion on Ovalentariae.

I am still sceptical about it. There is no critical character analysis (see discussion in Zootaxa 2946: „Morphological and Molecular Approaches to the Phylogeny of Fishes - Integration or Conflict?“). To treat the Cichlidae not as a part of the Perciformes but in their own Order Cichliformes looks strange (at least unusual). Seems that they excluded some species just only they do not fit the expected position in the tree („Twenty-five ... taxa were excluded from the final matrix because they had ... highly variable phylogenetic placement in preliminary analyses, ...“).
