a Species closely associated with campina and campinarana habitats of southwestern Amazonia (Stotz et al. 1996, Alonso 2002). 
and Whitney 2003), southwestern Venezuela, and 
the upper Rio Negro region of northern Brazil 
(Zimmer and Hilty 1997). The first record of this 
species in Acre was from Serra da Jaquirana, in 
dense submontane rain forest, in Serra do Divisor 
National Park. Two specimens were collected and 
deposited in the Goeldi Museum collection 
(Alonso and Whitney 2003: MPEG 52726, 
52727). The female we collected (MPEG 62025) 
in terra finne forest at the edge of the campinar¬ 
ana on 26 January 2007, represents the second 
record of this species for Acre. 
Fiery Topaz (Topaza pyra). This species is 
widely distributed in the western Amazon Basin, 
including Brazil, Peru, and Ecuador (Hu et al. 
2000), but is known from Acre only from three 
specimens collected by D. C. Oren and co¬ 
workers in Serra do Divisor National Park (MPEG 
52719, 52720, 52721). We collected a male 
(MPEG 62008) on 24 January 2007 in a mist 
net in open campina habitat. This record repre¬ 
sents the southernmost limit of the distribution of 
the species in the Amazon biome. Our record does 
not support the hypothesis that distribution of 
Fiery Topaz in southwestern Amazonia is related 
to blackwater river basins, as suggested by Hu et 
al. (2000). The drainage of our study area is 
exclusively whitewater, characterized by high 
concentrations of suspended sediments (Toivonen 
et al. 2007) in contrast with the region of Cruzeiro 
do Sul (where the first Acre records of Fiery 
Topaz were collected) which, near Serra do Moa, 
is dominated by blackwater streams (EG, pers. 
obs.). The Fiery Topaz has been recorded 
frequently in campinarana habitats, including Jau 
National Park (Borges et al. 2001) and" the 
municipality of Guajara in Amazonas State (A. 
Aleixo, unpubl. data). We believe the distribution 
of Fiery Topaz, in contrast with that of its 
congener Crimzon Topaz (T. pella ), is more 
closely related to campina and campinarana 
habitats than blackwater river basins. 
Golden-tailed Sapphire (Chrysuronia oenone). 
The first published record of this species from 
Brazil was provided by Ruschi (1957) based on 
two specimens collected in the vicinity of 
Benjamin Constant, in the State of Amazonas. 
There are only two additional Brazilian records, 
both from the upper Rio Jurua in Acre. One record 
is from the Alto Jurua Extractive Reserve (Whit¬ 
taker et al. 2002), and the other is from Serra do 
Divisor National Park (B. M. Whitney, unpubl. 
data; Guilherme 2009). The species appears to be 
common in the varzea habitats of the Jurua Basin. 
The species was observed on a daily basis at our 
study site, feeding on Inga spp. inflorescences in 
the varzea forest adjacent to the campinarana. A 
male (MPEG 62006) was collected on 31 January 
2007 in the varzea forest outside a school next to 
our base camp. This is the first specimen from 
Acre. 
Antbird (Myrmeciza spp.). We collected a male 
(MPEG 62088) on 24 January 2007 belonging to 
the Southern Chestnut-tailed Antbird (M. hemi- 
melaena) species complex, in terra firme forest at 
the edge of the campinarana. EG compared the 
specimen with 35 others in Museu Goeldi’s 
ornithological collection, collected at a variety 
of localities in Acre (Guilherme 2009), and noted 
the pileum was distinctly blackish in contrast with 
the gray ol those ot other specimens of Chestnut¬ 
tailed Antbird. This pattern was also observed in a 
male (MPEG 57134) collected in Tefe, Amazo¬ 
nas, a region with abundant campinarana habitat. 
The black pileum in these two specimens appears 
to agree with Zimmer’s (1932) description of a 
male Zimmer s Antbird (M. hemimelaena casta- 
nea) from Loreto, northwestern Peru. Isler et al. 
(2002) recently elevated this form to full species 
status, based on an analysis of morphological
