Atlapetes gutturalis brunnescens Chapman

Atlapetes gutturalis brunnescens Chapman, 1915a: 387 (Boquete, Chiriqui).

Now Atlapetes albinucha brunnescens Chapman, 1915 . See Hellmayr, 1938: 388, Paynter, 1978: 327–330, Wetmore et al., 1984: 589–590, Dickinson, 2003: 800, and Martínez and Sánchez, 2010: 96–97.

HOLOTYPE: AMNH 77855 (not 77885), adult male, collected at Boquete , 08.47N, 82.26W ( Siegel and Olson, 2008), Chiriqui, Panama, on 13 September 1901, by J.H. Batty.

COMMENTS: Due to a typographical error, the AMNH number of the holotype was cited incorrectly in the original description; the other data cited there are correct. Chapman examined 35 specimens of brunnescens, apparently in addition to the holotype. There are the following 26 paratypes in AMNH from Boquete, all collected by Batty in August–September 1901: AMNH 77854, 77856, 77857, 77862, 77863, 106594, and 106596–106615. There are two paratypes from Costa Rica: San Jose, AMNH 48190, male, 16 May 1889, C.F. Underwood; Irazu, AMNH 59839, male, 1 July 1892, A.H. Verrill (both are also paratypes of A. g. parvirostris , see above). One paratype is from Guatemala, AMNH 41064, unsexed and undated, from the G.N. Lawrence Collection (also a paratype of A. gutturalis griseipectus , see above). Of the six paratypes from Nicaragua, I found only five in AMNH: San Rafael del Norte, AMNH 101517, male, 101518, female, 101519, female, all collected in April 1907 by W.B. Richardson; Matagalpa, AMNH 102657, female, 12 September 1907, and AMNH 103228, male, 22 June 1908, both collected by W.B. Richardson (also holotype and paratypes, respectively, of A. g. fuscipygius, see above).

Of the above paratypes of brunnescens from Boquete, the following four had been exchanged to BIM in 1923, but would have been available to Chapman when brunnescens was named ; they were returned to AMNH in 1935 and were at that time renumbered: AMNH 106607 ( BIM no. 12626, AMNH new number 441699), AMNH 106613 (12624, 441701), AMNH 106614 (12623, 441700), AMNH 106615 (12625, 441702). I did not find AMNH 106595 in the collection ; it may have been exchanged without the catalog having been marked, but I have no information as to whether or not it could have been part of Chapman’s type series.
