(Roraimia is admittedly sister to an apparent Thripophaga/Cranioleuca/Limnoctites clade in the present study, but this clade lacks statistical support; Roraimia was embedded in the group formed by these three genera, with high support, in Moyle et al 2009 (the paper where Thripophagini was introduced, link in my previous post above) and in Derryberry et al 2011 ([
here]).
The present study and Derryberry et al 2011 also differ re. the position of Cranioleuca gutturata, by the way -- here, this species is sister to the rest of the focal group (so-so support; 80/.87) and the authors suggest it needs a new genus; in Derryberry et al, it grouped with Tripophaga (cherriei + fusciceps; type species so far unsampled) (so-so support as well; Bayesian PP < .95), and this group then formed a clade with Roraimia (high support; Bayesian PP > .95); gutturata is now included in Thripophaga by various authorities based on the 2011 results.)
