Well developed uropatagium, the median extension reaching the lower third of tibia. 

 Calcar as long as foot including claws. Plagiopatagiimi inserts at tarsus. Tail (ca. 8 mm) 

 present, projects dorsally in first quarter of the uropatagium as a touchable stiuiip (fig. 7). 



Brachyphylla 



Comparativlely very large bats, head not visibly elongated. Nose leaf without spear but 

 showing two concentrically lining, deep circular wrinkles around the nostrils. Tlius, the 

 face (fig. 8) resembles that of the Desmodontinae (true vampires). Strikingly strong thumbs 

 and large, strong feet. Tlie uropatagium forms a well developed interfemoral membrane. 

 No externally visible tail, no calcar, the plagiopatagium inserts at the tarsus. Pelage colour 

 varies, with head and back usually light brown, yellowish to ivory, ventral side most often 

 brown (lighter tlian dorsally). Tlie (naked) plagiopatagium is darker, almost black. 

 B. nana: Forearm length 56-59 mm. 

 B. cavernarum: Forearm length 63-69 mm. 



Erophylla 



Large blossom bat with conical, moderately elongate muzzle. Nose leaf without spear, 

 similar to Brachyphylla, but more delicate and with small central tip. Resembles the nose 

 of Old World Rliinopomatidae ("pig snout"). Uropatagium restricted to a narrow fringe 

 being distinctly projected by the tail. Very short calcar. 



E. sezekomi (fig. 9): Forearm length 45-49 nmi. Long thumb (1. phalanx I = 7nmi). 

 Metacarpaha: III>IV<V (III >=V); 1. phalanges: III > IV >=V. Uropatagium short, 

 marginal outline wedge-shaped, ruiming from very short calcars to the tail tip. 

 Plagiopatagium inserts at distal tibia immediately above the ankle joint. Pelage coloration 

 pale yellow brown to reddish grey, slightly blotchy ("frosty", "mangy"), ventral view and 

 face lighter. Short tragus witli smooth margin.
