COMMENTS: Hartert gave Mayr’s unique field number of the holotype in the original description, the only specimen he collected. There was one paratype: AMNH 698107, [male], collected near Humboldt Bay by J.M. Dumas; this specimen is also a paratype of D. g. diversum, above. For more information on Mayr’s expedition, see Hartert (1930a: 18–19) and Mayr (1930: 20–26).
