Dacus (Paradacus) Perkins, n. comb. 
Paradacus Perkins, 1938, Roy. Soc. Queens- 
land, Proc. 49(11): 143. 
This subgenus is very similar to D. {Zeugo- 
dacus) except that prescutellar bristles are ab- 
sent. There appear to be just three described 
species which fit in Paradacus. Hering’s place- 
ment (1952^.* 266) of Zeugodacus pendkhuryi 
Perkins under this combination was probably 
an error. [See under Dacus {Zeugodacus) 
pendkhuryi^ Paradacus minimus Hering {loc. 
cit.) should very probably also belong in 
Zeugodacus. 
GENOTYPE: Paradacus fulvipes Perkins. 
KEY TO ALL KNOWN SPECIES OF 
Dacus (Paradacus) 
1. Mesonotum with three postsutural yellow 
vittae. Wings with a brown transverse 
marking in median portion. (Moluccas)

Mesonotum with two postsutural yellow 
vittae. Wings without transverse markings

2. Abdomen chiefly pale reddish brown, 
third tergum black only along anterior 
margin and slightly darkened on sides; 
fourth and fifth terga all rufous except for 
indistinct discolorations on sides. Cross- 
vein m slightly infuscated. (Borneo) .... 
fulvipes (Perkins) 
Third to fifth terga black with a yellow 
submedian spot on each side. The m 
crossvein not infuscated. (Lesser Sunda 
Islands) minimus (Hering) 
Dacus (Paradacus) fulvipes 
(Perkins), n. comb. 
Paradacus fulvipes Perkins, 1938, Roy. Soc. 
Queensland, Proc. 49(11): 143-144, fig. 8. 
This species is apparently closely related to 
D. minimus (Hering) and is separated by the 
paler coloring of the abdomen and the slightly 
fuscous m crossvein, as stated in the above 
key. There are probably other more satisfac- 
tory characters for separating these, but they 
are not evident in the original descriptions. 
Perkins’ wing photograph is very poor and 
is of little value in distinguishing his species. 
Length: Body, 6.0-6. 5 mm.; wings, 5.5- 
6.0 mm. 
TYPE locality: Bettolan, N. Borneo. 
Type in the Selangor Museum. 
This species is known only from the type 
male. 
Dacus (Paradacus) minimus 
(Hering), n. comb. 
Paradacus minimus Hering, 1952, Naturf. Ges- 
ell. in Basel, Verhandl. 63: 42-43, fig. 1. 
From Hering’s discussion of this it would 
appear to fit just as well in Dacus {Zeugodacus)
