A Brumfield et al. 2007 paper suggests that lots more generic changes will be needed in this family. For example, look at all the different nodes Myrmeciza comes out in:

Isler, Bravo & Brumfield (in review). Systematics of the genus Myrmeciza (Aves: Passeriformes: Thamnophilidae) based on integration of phylogenetic, morphological, behavioral, and ecological data: the dilemma of determining limits of genera.

AOU-SACC:

The genus Myrmeciza is widely suspected of being polyphyletic (e.g., Ridgely & Tudor 1994, Zimmer & Isler 2003), and this has been confirmed by recent genetic data (Irestedt et al. 2004, Brumfield et al. 2007). Myrmeciza ferruginea, M. ruficauda, M. loricata, M. squamosa, M. pelzelni, M. hemimelaena, M. atrothorax, and M. griseiceps were formerly (e.g., Cory & Hellmayr 1924) placed in a separate genus, Myrmoderus, but genetic data (Brumfield et al. 2007, Moyle et al. 2009) indicate that this would still be a polyphyletic genus. Peters (1951) removed all but loricata and squamosa from Myrmoderus; atrothorax was placed in a separate genus, Myrmophylax, and the rest were transferred to Myrmeciza. Zimmer (1932b) and Meyer de Schauensee (1966, 1970) merged Myrmoderus and Myrmophylax into Myrmeciza. Genetic data (Brumfield et al. 2007, Moyle et al. 2009) indicate that atrothorax is indeed distant from other Myrmeciza. SACC proposal needed to resurrect Myrmophylax..<wait Bravo/Brumfield MS> Zimmer & Isler (2003) noted that Myrmeciza ferruginea, M. ruficauda, M. loricata, and M. squamosa likely form a monophyletic group based on plumage, voice, and nest structure. Brumfield et al. (2007) found that the Myrmeciza sampled fell into 5 groups: (a) atrothorax; (b) hyperthyra; (c) fortis, immaculata, goeldii, and melanoceps; (d) hemimelaena; and (e) exsul and berlepschi. The type species for the genus, longipes, has yet to be placed in a gene-based analysis. When all taxa are sampled, it is likely that Myrmeciza, as constituted for the last 60+ years, may set a record for degree of polyphyly.

Need to include types of genera in phylogenetic analyses

Hi friends,
I have been looking at the taxonomy of the Thamnophilidae. It is clear from a number of studies that the traditional genus Myrmeciza is undoubtedly massively polyphyletic. But none of these studies have used the type of Myrmeciza, namely M. longipes. So this prevents one from reassigning species to new genera because no-one can be sure where longipes fits in. So could I implore authors of studies involving genetic sequencing to ensure that they at least have the types of all relevant genera included in their dataset!

It's coming out of LSU. Sometimes it better to get it right than to get it right now.

When I was looking at this 8 years ago it was a mess and the problem isn't longipes (which I believe is its own clade). The problem is assigning the different "Myrmeciza" to other clades and getting those clade fully described so that the correct name change is only done once. If you don't handle those clades fully in the analyses you risk changing the name once only to change it again when you realize another taxon you didn't consider has priority. Hence handling "Myrmeciza" is akin to handling Thamnophilidae. Hence LSU and the Brumfield lab took this one on.

This isn't going to be as big of a deal as Dendroica, but sort of.

Re: Need to include types of genera in phylogenetic analyses

John,

I fully agree with you; vouchered samples of types of relevant taxa should be included in taxonomic studies. That's one of the main points we wanted to make when naming a new genus for four species previously placed in Terenura (http://www.museum.lsu.edu/Bravo/Publications_files/Bravoetal2012MPE.pdf).
The reason why M. longipes has nerver been sampled in the published literature is that none of those studies meant to specifically unravel phylogenetic relationships of Myrmeciza.

Also, Matt's point is spot on. Many genus-level taxonomic decisions in Thamnophilidae not only depend on including types, but also on having complete sampling of major clades in the family. That's why decisions regarding some groups have taken a while. We are working on Myrmeciza and other interesting cases in the family and soon those studies will be published. Stay tuned!

Cheers,

Gustavo Bravo

Thanks, alytothrix. :t:

I have not yet seen Isler Bravo & Brumfield, 2013, or the diagnoses of new genera. I assume the following etymologies apply, but would appreciate confirmation or otherwise;

Ammonastes Gr. ammos sand; nastes inhabitant < naio to dwell.
Ampelornis Gr. ampelis bird mentioned by Aristophanes, not further identified; ornis bird.
Aprositornis Gr. aprositos inaccessible, unapproachable; ornis bird.
Hafferia Dr Juergen Haffer 1932-2010 German geologist, palaeontologist, ornithologist.
Inundicola Latin inundatus inundated, flooded; -cola -dweller < colere to inhabit.
Poliocrania Gr. polios grey; kranion skull (cf. genus Cranioleuca)
Sciaphylax Gr. skia shadow, shade; phulax watcher, sentinel.

I note that Schistocichla Todd, 1927, has been subsumed into Myrmelastes P. Sclater, 1858.

Ampelornis = "from the Greek ampelos (vine) and ornis (bird), reflecting the viny habitat often occupied by this species."

Otherwise all correct, James.

TiF Update October 6

Browsing the antbirds I came across the genus Akletos Dunajewski, 1948, the type of which is Akletos peruvianus Dunajewski, 1948, which is apparently the female of Inundicola melanoceps (von Spix, 1825). If so, should Akletos Dunajewski, 1948, replace Inundicola Bravo Isler & Brumfield, 2013?

And how about Diallectes Reichenbach 1850, which is a questionably valid genus of dubious application (may still lack a type species ?), but has been used for some of these Myrmeciza (and some species in other genera) in the past. It could have been worthwhile using, fixing usage of or redescribing some of these older names. There are some issues around how big or small some of these groupings are also, but that is more a thing of taste than priority.

I know I should get out more, but, according to Cory & Hellmayr, 1924, Catal. Birds Americas, III, p. 45, Diallactes Reichenbach, 1850, is a synonym of Taraba Lesson, 1830, with type Taraba major (Vieillot, 1816).

TiF Update October 10:
The genus name Hafferia (Isler et al., 2013) has been replaced by Akletos (Dunajewski 1948, type melanoceps). Dunajewski named the female as a separate species and genus, not realizing that the male was previously known. The SACC has it listed under “Hybrids and Dubious Taxa”. That Dunajewski named the female should make no difference as far as the Code is concerned, thus Akletos has priority.

I obviously have a severe case of myrmecizitis, but how can Inundicola melanoceps (von Spix, 1825) (the type of Inundicola Isler et al., 2013) be the type of Hafferia Isler et al., 2013, of which the type if Hafferia immaculata (de La Fresnaye, 1845)? Or have Hafferia and Inundicola been merged already?
I'll go and rest in a darkened room now!
