Now Pteridophora alberti Meyer, 1894 . See Mayr, 1962d: 197 ; Gilliard, 1969: 184–192 ; Diamond, 1972: 339–340 ; Coates, 1990: 484–486 ; Cracraft, 1992: 29–30 ; Frith and Beehler, 1998: 305–314 ; and Frith and Frith, 2009b: 473 . HOLOTYPE : AMNH 678693 , female, collected on Schrader Mountain , 05.00S , 144.05E (PNG General Reference Map, 1984), Schrader Mountains , East Sepik Province , Papua New Guinea , on 11 June 1913 , by Joseph Bürgers (no. 2064). From the Rothschild Collection. COMMENTS: Rothschild cited Bürgers’ number of the holotype in the original description. Only the single specimen was in the Rothschild Collection when this form was named; it had been exchanged from ZMB ( Rothschild, 1921a: 281 ), where the Bürgers collection is housed. Rothschild does not make it clear whether or not he saw the other two female specimens; the male was unknown. Most recent authors consider Pteridophora alberti monotypic.
