Figure 15. Cladogram of diphaglossine genera based on larval characters. Numbers 
refer to the characters listed in Table 3. Black rectangles represent presumed apo- 
morphic characters; white rectangles represent plesiomorphic characters. Character 
109 appears to be variable in Crawfordapis. 
The larval cladogram corroborates the currently recognized 
diphaglossine classification based on adult characters (Michener, 
1966). Recognition of the Caupolicanini (Ptiloglossa, Crawfordapis, 
Caupolicana) is supported by the presence of the unusual salivary 
plate (character 83, Fig. 9) and the rounded, nonprojecting inner 
maxillary surface (character 65).
