Now Iole propinqua aquilonis ( Deignan, 1948 ) . See Dickinson and Gregory, 2002 , Dickinson and Dekker, 2002b: 103, and Dickinson et al., 2002b: 130. HOLOTYPE : AMNH 565615 , unsexed adult, collected at Bac Kan , 22°08′N , 105°50′E ( Deignan, 1948: 4 ), Bac Kan Prov. , North Vietnam , on 8 December 1926 , by Jean Delacour and Pierre Jabouille (no. 1652). From the Rothschild Collection. COMMENTS : The AMNH number of the type was given in the original description. Deignan listed five males , one female , and two unsexed specimens, all from Hoixuan Prov., as paratypes . There are in AMNH six males and two unsexed specimens from Hoixuan collected by Delacour and Jabouille, AMNH 290847–290854. Because Deignan (1948: 1) borrowed specimens from many museums, there remains the possibility that a female specimen, collected by Delacour and Jabouille at Xoixuan, will be found in another collection.
