aBase pairs of cytochrome b sequenced by J. L. Patton and his colleagues. 
bIdentified as Marmosops parvidens in analyses previously reported by Mustrangi and Patton (1997) and Patton et al. (2000). 
‘Identified as Marmosops albiventris in analyses previously reported by Mustrangi and Patton (1997). 
didentified as Marmosops dorothea or M. impavidus in analyses previously reported by Mustrangi and Patton (1997) and Pat-

ticucho (= Cuti Khuchu on recent topo- 
graphic maps), which he recorded as having 
an elevation of 2967 m above sea level (but 
see appendix 2: locality 16). The site is de- 
scribed in his fieldnotes as follows: 
Since our arrival [six days ago] we have not seen the 
sun for more than an hour a day. Clouds move up the 
valley in the morning at around 8:30AM and form 
just below our camp. Intermittent rain and mist are 
the order of the day. The temperature here stays rel- 
atively constant, between 55 and 65° F [13-18° C]. 
The forest here is very damp—many lichens, moss 
and ferns on branches of trees. We have trapped in 
three habitats here: cloud forest (relatively undis- 
turbed), 2nd growth forest—with much bamboo; and 
artificial clearings under power lines ... We are very 
near treeline here; as one looks up the valley the trees 
thin out and disappear at a fairly distinct “‘line’’ about 
300 m above camp. Looking down the valley the 
trees get noticeably higher ... [3 October 1979] 
Both specimens of Marmosops creightoni 
from Cuticucho were taken in the cloud for- 
est with snap traps: one (UMMZ 155999) at 
the base of a tree and the second (UMMZ 
156000) on a low branch. Creighton also col- 
lected five species of sigmodontine rodents 
at this site, of which Akodon mimus, Oxy- 
mycterus nigrifrons, and two undescribed 
forms of Thomasomys (“‘sp. 1” and “‘sp. 3”
