Hi all!
Does anyone have info on the systematic (and true taxonomic) whereabouts for Chestnut-headed Crake (Anurolimnas/Rufirallus castaneiceps)?
There seems to be an extreme lack of consensus between IOC/Clements/BLI, both concerning correct genus and priority. Clements puts it in Anurolimnas, along with viridis and fasciatus. IOC limits Anurolimnas to castaneiceps, placing the others in Laterallus. BLI/HBW moves castaneiceps and viridis to Rufirallus (citing priority issues: Bonaparte, 1856 over Sharpe, 1893).
In the Garcia-R (2014) tree, they have, peculiarly, a tight clade of "Anurolimnas viridis" and "Laterallus viridis" (whatever that means, a typo for castaneiceps or did they only sample viridis?) sister to Laterallus, Haplocrex, the Dot-winged Crake and Coturnicops. Fasciatus is closest to melanophaius and together sister to the remaining group.
So viridis and fasciatus are definitely "Lateralline". But what about castaneiceps? John Boyd places it, for some unexplained reason, as basal to a clade with Rallus, Gallirallus and the like, way off from Laterallus. Can't find any genetic studies on it. And does Rufirallus have priority over Anurolimnas or not?
