Diagnosis 
Nyctimene c. cephalotes differs from N. c. aplini as 
described in the earlier diagnosis of that 
subspecies. 
Description 
Skull moderately long 30.1 ± 0.68, narrow with 
braincase breadth 12.8 ± 0.37 and zygomatic width 
19.8 ± 0.72; palate posterior margin V or sharp U 
shape; mesopterygoid fossa moderately wide 5.2 ± 
0.20; C'M 1 tooth row moderately long 10.2 ± 0.43; I 1 
generally closely opposed to C 1 , sometimes in 
contact with C 1 ; incisive foramen subcircular, 
small, generally not reaching posteriorly to a line 
joining P 2 -P 2 anterior face; frontal between 
postorbital process flat or only very slightly 
basined. 
Apart from the above characteristics and 
generally smaller size, the shape of the skull. 
dentary and dentition is very similar to N. 
cephalotes aplini. 
Externals 
Forearm moderately long 63.4 ± 2.07; ear 
moderately long 14.2 ± 0.61. Wing membrane 
generally connected between phalanx 1 of digits 2 
and 3 (46%, N = 13) but also commonly from 
phalanx 1 of digit 3 (29%, N = 8) and commonly 
from phalanx 1 of digit 2 (25%, N = 7). 
Pelage 
Males and females with similar coloured dorsum 
but females with paler head, face and ventral 
pelage and paler patagia. The dorsal surface of 
males and females predominantly Drab but tipped 
with Olive Brown on shoulders and patchily with 
Fawn Color on lumbar and lower back regions; 
median dorsal stripe from crown of head to base of 
tail Olive Brown varying in breadth from 2-5. 
Hairs in mid dorsal region c. 11 long, basal one- 
third Drab. On head and behind ears to shoulders. 
Clay colour in males; in females a paler Straw 
Yellow. On face dark Smoke Gray in males; in 
females a paler Smoke Gray. Ventral surface in 
males Cream Color on chest and abdomen with 
neck and flanks Buff Yellow to Buff; in females
