Figure 24 



1940. Hyla vilsoniana krausi Hellmich, 1940a, p. 8 (type locality, Laguna de la 

 Guitarra, Paramo de Sumapaz, Cundinamarca, Colombia) — Rivero, 

 1963a, p. 95. 



Diagnosis.' — A large frog of the labialis group with a well-developed 

 patagium which is bright blue in life. 



Hyla labialis krausi differs from H. platydactyla in that the groins 

 and posterior surfaces of the thighs range from uniform to lightly 

 speckled but are never distinctly and brightly mottled; it differs 

 from H. labialis in having longer legs and the length of the crus 

 more than half the head-body length. 



Description. — ZSM 102/1937 (holotype), from Laguna de la 

 Guitarra, Paramo de Sumapaz, Cundinamarca, Colombia. Vomerine 

 teeth in two short, transverse series, lying rather far apart between 

 the small, rounded choanae; tongue three-fourths as wide as mouth 

 opening, broadly rounded, its posterior border free and very shallowly 

 notched. Snout moderate, somewhat U-shaped when viewed from 

 above, broadly rounded in profile, the upper jaw extending but little 

 beyond lower; nostrils as dorsal as lateral, slightly projecting, their 

 distance from end of snout about equal that from eye, separated from 

 each other by an interval about equal to their distance from eye. 

 Can thus rostralis well defined; loreal region slightly concave and 

 somewhat oblique, the upper lip flaring out a little below it. Eye
