Fig. 59: Relation SIZE to widtii over canini: comparison between Phyllonyctens (□) and outgroup (+) 



With increasing skull size, the anterior width of the palate increases to a proportionally 

 less extent, the gradient of the reduced elliptic major axis clearly remaining below 45 

 degrees (tan alpha = 0,57). It is, however, remarkable that the genera Erophylla and 

 Phyllonyctens having been simmiarized within the subfamily Phyllonycterinae do not 

 differ from the outgroup in this respect (fig. 5 9). 



In the Glossophaginae, size-dependent shift in proportion follows the same pattern; the 

 distances between the canine teeth are, however, smaller at equal body size in a genus-
