(Tyrannidae; Ϯ Rufous-webbed Bush Tyrant P. rufipennis) Gr. πολιος polios grey; genus Xolmis Boie, 1826, monjita; "Polioxolmis, new genus. TYPE SPECIES: Muscisaxicola rufipennis Taczanowski, 1874 ... ETYMOLOGY: From the Greek polios meaning ashy-gray, in reference to the predominant color of the plumage" (Lanyon 1986); "It shows some resemblance to Xolmis ... If not in Cnemarchus it should have a new genus erected for it. Probably near Xolmis ... In fact except for a little more slender bill, it fits best in Xolmis" (Zimmer MS in Lanyon 1986).
