Pteridophora alberti bürgersi Rothschild

Pteridophora alberti bürgersi Rothschild, 1931: 253 (Schrader Berg, Sepik River District).

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.
