Australian Fruit Flies — Hardy 
129 
tapered, narrow, and truncate at its apex. 
Legs: Entirely yellow; the spurs of the middle 
tibiae are comparatively short, their length 
about equal to the width of the tibia. Wings: 
Chiefly hyaline, with a distinct costal and 
cubital band. The first two sections of the 
costa are faintly yellow-fumose and are de- 
void of microtrichia except for the apical 
part of the second section. The costal band 
is brownish, narrow, and confined to a thin 
strip which does not extend into cell Rg 
except at the apex. The costal band extends, 
at least faintly, almost to the tip of vein 
Mi +2 (Fig. 5b). The yellowish cubital streak 
is broad at its base, filling all of the base of 
cell M 4 nearly to the top edge of the m-cu 
cross vein. The yellow streak fades out at 
about the apex of the cubital cell and joins 
the gray spot caused by the longer, more 
closely spaced microtrichia along vein Cuifl- 
1 st A and in the apical portion of cell 1 st A. 
The apex of vein M 3+4 possesses a gray, 
faintly yellowish spot formed by the closely 
set hairs. The cubital cell is strongly narrowed 
and is elongated. The narrowed portion of 
this cell is over three times longer than the 
distance from the apex of this cell to the 
wing margin. Abdomen: Pale yellow, except 
for the oblong brown to black spot in the 
middle of the fifth tergum and for the whitish 
hind border of segment 2 . The pile is pale 
except for the long black hairs on the sides 
of the third tergum. 
Length: Body, 4.7-5 . 0 mm.; wings, 4.4- 
4.7 mm. 
FEMALE. The cubital streak is not developed 
beyond the apex of the cubital cell. This cell 
is much shorter and not as narrow as in the 
male. The narrowed portion of the cell is 
one and one-half times longer than the dis- 
tance from the apex of the cell to the wing 
margin. Ovipositor: Yellow and short, scarcely 
extruded farther than the length of the fifth 
tergum. The basal section of the ovipositor 
is about equal in length to the fifth tergum. 
The ovipositor is comparatively short and 
broad (Fig. 5 c); the entire length (when 
mounted) is about 3.7 mm. The piercer is 
approximately IT mm. long by about 0.17 
wide. It is broadly tapered toward the apex, 
and the setae are quite distantly spaced from 
the apex (Fig. 5d), The setae are about 0.1 
mm. from the apex. This distance is compar- 
able to four times the length of the longest 
(distad) pair of setae. The apex of the oviduct 
is about 0.22 mm. from the tip of the ovi- 
positor. The inversion membrane (segment 8) 
is 1.3 mm. long by 0.33 mm. wide at its 
broadest point. The rasper extends to within 
0.4 mm. of the base of the segment. The 
basal segment of the ovipositor is about 1.35 
mm. long by 1.0 mm. wide, and the spiracles 
are about 0.45 mm. from the base of the 
segment measured on the lateral margins. 
Length: Body, 4. 8-6.0 mm.; wings, 4.5- 
5.7 mm. 
TYPE LOCALITY: Bowen, Queensland, ex 
Capparis laurifolia. 
Type No. 3135 in the Queensland Museum. 
A large series of specimens has been studied 
from Ellis Beach near Cairns, Queensland, 
Jan., 1950 , ex Capparis lucida\ and from 
Mowbray River, Queensland, ex Capparis 
lucida, Eeb., 1950.

Lond., Proc., Ser. B., Tax. 7(5): 117. 
This subgenus is identical with Dacus 
(Asiadacus) except that the males have no 
supernumerary lobe in the wings. It has pre- 
viously been known only from one African 
species, the genotype. As a result of the 
studies reported here, it is quite apparent that 
two of the Pacific species, D. absonus (Hering) 
and D. calophylli (Perkins and May), which 
were ascribed to the subgenus Asiadacus, actu- 
ally belong in the subgenus Gymnodacus. These 
two are definitely borderline cases linking the 
two groups, but the lack of development of 
the supernumerary lobe in the wings of the 
male places them more closely into Gymno-
