Buarremon assimilis nigrifrons Chapman

Buarremon assimilis nigrifrons Chapman, 1923a: 11 (Las Pinas, 3600 ft., Alamor Mts., Prov. Loja, Ecuador).

Now Arremon torquatus nigrifrons (Chapman, 1923) . See Hellmayr, 1938: 418–419, Dickinson, 2003: 799, Cadena et al., 2007, Ridgely and Tudor, 2009: 644, 699, Cadena and Cuervo, 2010: 152–176, and Flórez-Rodríguez et al., 2011.

HOLOTYPE: AMNH 172533 , adult male, collected at Las Piñas , 3600 ft, northeast of Alamor, 04.02S, 80.02W ( Paynter, 1993), Alamor Range, Loja, Ecuador, on 11 September 1921, by George K. Cherrie (no. 23956) and Geoffrey Gill.

COMMENTS: Chapman gave the AMNH number of the holotype in the original description and the correct data relating to that specimen. Unfortunately , the type label was tied on the wrong specimen ( AMNH 168238 , with different data). An AMNH type label has been added to the holotype ; the specimen with the incorrect type label, a paratype, remains in the type collection with a label explaining the problem because it has for so many years been accepted as the type. Chapman (1923b: 277) listed 45 specimens examined, including the type but omitting two unsexed specimens that would have been available to him when nigrifrons was described. There are thus 46 paratypes: Ecuador, Alamor, AMNH 168237–168242 , 172534-172537 , six males and four females ; Guaniche , AMNH 172538–172540 , two males, one unsexed specimen ; Guachanoma´ , AMNH 168243 , one male ; Cebollal , AMNH 172541 , one male ; Las Piñas , AMNH 172532 , one male ; La Puente , AMNH 172546 , one male ; Punte Santa Ana , AMNH 168252– 168254 , three females ; Loja, AMNH 130361 , 130362 , two males ; Salvias , AMNH 168250 , 168251 , two females ; Portovelo , AMNH 168244–168249 , 172542–172545 , six males, three females, one male ?; Zaruma, AMNH 130357–130360 , 130363 , two males, one immature male, two females. Peru: Palambla , AMNH 175702–175708 , six males, one sex?. Of these paratypes, the following have been exchanged: AMNH 130358 , 168240 , 172534 , and 172536 to MCZ in July 1928 ; AMNH 168244 and 168248 to ANSP in July 1928 ; and AMNH 172540 to MECN in July 1984 .
