Dacus (Gymnodacus) Munro 
Dacus {Gymnodacus) Munro, 1938, Roy. Soc. 
London, Proc., ser. B, Tax. 7(5): 117. 
This subgenus is distinguished from D. 
{Strumeta) only by the lack of rows of cilia 
on each side of the third abdominal tergum 
of the male. 
genotype: Dacus mesomelas Bezzi.

Dacus {Gymnodacus) calophylli (Perkins and 
May) Hardy, 1951, Pacific Sci. 5(2): 130, 
figs. 6a-b. 
This species has been adequately described 
and figured in the above references. This is 
the first time it has ever been recorded outside 
the type area. 
TYPE locality: Cairns, Queensland. 
Type at the University of Queensland. 
Sixteen specimens are on hand from Singa- 
pore, Malaya, May, 1949, ex Calophyllum 
inophyllum (N. L. H. Krauss).

The subgenus Neodacus differs from Dacus 
{Strumeta) only by lacking prescutellar bristles. 
GENOTYPE: Dacus {Neodacus) newmani 
(Perkins).

Dacus {Neodacus) hakeri (Bezzi) Hardy, in 
press, Wash. Ent. Soc., Proc. 
This species has been adequately described 
in the references cited above. It is differentiated 
from other Dacus {Neodacus) which have the 
costal band expanded into a large apical spot 
by having the mesonotum extensively marked 
with black and with just two postsutural yel- 
low vittae. 
TYPE locality: Davao, Mindanao, host 
unknown. 
Type in the U. S. National Museum. 
We have not seen this species. 
Dacus (Nesodacus) Perkins, n. comb. 
Nesodacus Perkins, 1937, Roy. Soc. Queens- 
land, Proc. 48(9): 57. 
This subgenus is most closely related to 
Dacus {Neodacus), differing only in the absence 
of a row of cilia on the sides of the third 
abdominal tergum of the male. It also is close 
to Dacus {Dacus), differing only in having a 
supernumerary lobe in the wing of the male. 
It is differentiated from Dacus {Strumeta) by 
the absence of prescutellar bristles and by the 
absence of cilia on the third tergum of the 
male. This genus was not represented in the 
specimens which were studied, but a key to 
the species is included to make this paper 
more complete. The species longicaudatus 
(Perkins) is known only from the type female, 
and there is some question as to whether it 
belongs in Dacus {Nesodacus) or Dacus {Neo- 
dacus) . 
genotype: Chaetodacus atrichus Bezzi,
