Dacus (Zeugodacus) caudatus Fabricius

This species has often been erroneously 
recorded from many world areas (including 
the Philippines) where it apparently does not 
occur. It is obvious that most of the references 
to D. caudatus in the literature should actually 
pertain Co D. hageni de Meijere. To clarify 
this situation, we feel that it is appropriate 
to discuss caudatus with the Philippine Dacini. 
It is differentiated from hageni by the presence 
of a brown cross band extending over the m 
crossvein (Fig. 23c). Refer to our notes under 
D. {Zeugodacus) hageni de Meijere. It appears 
to fit the characteristics of hageni other than 
for the wing and the ovipositor (Fig. 2'bh). 
Ovipositor: The exposed portion, in situ, is 
slightly longer than the combined lengths of 
segments four and five. The extended ovi- 
positor (Fig. 23^5^) measures about 5.5 mm. 
The piercer measures about 1.8 mm. by 0.21
