Perkins’ specimen was from Bukit Kutu, 
Selangor. It is in the Selangor Museum. We 
have not seen this species. 
Dacus (Zeugodacus) maculatus 
(Perkins), n. comb. 
Zeugodacus caudatus var. maculatus Perkins, 
1938, Roy. Soc. Queensland, Proc. 49(11): 
139-140. 
This appears to be a distinct species rather 
than just a variety of D. hageni {caudatus of 
Perkins). Perkins’ description is very incom- 
plete, but maculatus seems to be distinctive 
because of the presence of a large black spot 
at the apex of the scutellum; because of the 
costal band not extending through the mid- 
dle portion of cell R3 and not strongly ex- 
panded into a large apical spot; because of the 
three postsutural yellow vittae and the yellow 
humeri; also by having the median portion 
of the face black. Perkins states, "The facial 
markings are in the form of two triangular 
black spots, whose apices reach the oral mar- 
gin, and whose bases run along the transverse 
furrow of the carina, meeting in the middle.’’ 
TYPE locality: Bukit Kutu, Selangor. 
Type in the Selangor Museum. 
Known only from the type female.

This species is readily distinguished from 
other Zeugodacus known from this region by 
the presence of a black transverse band across 
the median portion of the face (Fig. 2Ga), It 
resembles hageni in most other respects. Dacus 
diffusus Walker (I860: 153) appears to be 
closely related to maculipennis. 
MALE. Head: Three pairs of inferior fronto- 
orbital bristles are present, the lower two pairs

are situated very close together. The front is 
rather broad, is almost as wide as one eye and 
about 1.25 times as long as wide. The front 
is slightly expanded on the lower portion, and 
indistinct brown spots are present at the base 
of the bristles. The antennae are rufous, with 
a brownish tinge in the ground color of the 
third segment. The third segment is four 
times as long as wide and is about equal in 
length to the face. Thorax: Predominantly 
black with the usual yellow areas, including 
three moderately broad postsutural yellow 
vittae; the median one is pointed on each 
end and extends from just behind the suture 
to the prescutellar bristles. The scutellum is 
yellow except for a very narrow black basal 
band. Legs: Chiefly yellow to rufous with 
discolorations of brown over the hind tibiae, 
on the ventral surfaces of the front tibiae, and 
on the apicodorsal surfaces of the front fem- 
ora. Wings: The costal cells are hyaline and 
devoid of microtrichia except at the apex of 
the second cell. The costal band is compara- 
tively narrow through most of its length but
