Notes 
Males of H. macalpinei are distinguishable from those of 
other species of th efuscinevris group with largely infuscated 
antennal segment 3 and no hypopleural setulae by the shape 
of the surstylus (Fig. 26). Usually the proepimeral bristle is 
absent, but in the holotype of H. macalpinei a very small such 
bristle is present on the left side only. Usually the fore femur 
has an elongate dark grey posterodorsal mark before mid¬ 
length which is well separated from the subapical posterior 
dark mark, and the often concealed anterior surface has a 
broad brown basal zone, which is generally separate from 
the brown distal zone. Helosciomyza australica appears to 
be consistently without any brown zone on the basal half of 
the fore femur. Coloration of the fore femur in H. obliqua is 
variable; some specimens approach the condition seen in H. 
macalpinei, but the two dark marks on the fore femur, as seen 
in posterior view, are generally less strongly differentiated, 
and a small proepisternal bristle is generally present, at 
least in the limited available material. However, certain 
identification of some female specimens is not achievable. 
Genus Neosciomyza Barnes 
Neosciomyza Barnes, 1981: 61. Type species (original 
designation): Helosciomyza anhecta Steyskal. 
Notes 
This genus is distinguished as indicated in the key to genera. 
Reasons are given under the genus Luta for the exclusion of 
L. luteipennis from Neosciomyza.

Type material (re-examined D.K.M.). Holotype (?. 
Tasmania: Mount Barrow, 3000 ft. [c. 1040 m, Launceston 
district] 25.U960, D.K.M. (AM K264502). Glued to card 
point. Paratype. Tasmania: 16 mi. [c. 26 km] NE of 
Cradle Mountain, 5.L1960, D.K.M. (AM). On card point, 
now much damaged, postabdomen in micro-vial on pin. 
Dimensions of holotype. Total length 5.8 mm; length of 
thorax 2.8 mm; length of wing 7.3 mm. 
Distribution. Tasmania: northern districts. 
Notes 
Neosciomyza anhecta is very similar to N. peckomm and is 
distinguished as indicated under that species. I have seen no 
specimens additional to the type specimens collected in 1960.

Description (male, female). Rather large, slightly elongate, 
predominantly dull tawny fly, with almost unmarked wing; 
most parts pruinescent and non-shining. 
Coloration (clean specimens which have not passed 
through alcohol). Head, in large part, tawny-orange; postfrons 
with darker tawny-brown ocellar region, largely covered with 
greyish pruinescence, and paler grey to yellowish-pruinescent 
orbital margin; face and cheeks paler than rest of head, 
yellowish with whitish pruinescence. Antenna largely dark 
brown; more basal parts of segment 3 tawny. Prelabrum 
yellow to grey-brown; palpus tawny-yellow basally, grey- 
brown on distal third or more. Thorax dorsally tawny-orange; 
mesoscutum broadly creamy grey-pruinescent on lateral 
margins, with narrower pale-pruinescent dorsocentral stripe 
interrupted at suture and between the two dorsocentral bristles, 
and very narrow less distinct median pale-pruinescent stripe; 
humeral callus pale-pruinescent, except on ventral margin 
near spiracle; scutellum without pale-pruinescent margins; 
pleura tawny-orange, very generally covered with dense pale 
greyish to yellowish pruinescence, mesopleuron thus without 
any exposed tawny areas. Legs largely pale tawny-orange; all 
femora broadly brown-black at apices; tibiae all brown-black 
apically, mid and hind tibiae also with brown basal zone; tarsal 
segment 3 partly brown, segments 4 and 5 usually darker 
brown. Wing: membrane slightly tinged with yellow-brown, 
less intensely so than in Luta luteipennis ; subcostal cell with 
broad yellow-brown blotch restricted to part of cell near end of 
subcosta; veins tawny; anterior and discal crossveins without 
trace of darker pigmentation. Halter yellow. Abdomen tawny, 
without distinct darker markings; tergites 1 to 4 covered with 
fine rather dense greyish pruinescence; tergite 5, in contrast, 
smooth and glossy, pruinescent only near lateral margins; in 
male stemite 8 and in female tergite 6 glossy like tergite 5. 
Head slightly higher than long, slightly angularly 
produced anteriorly so that face is oblique in profile; cheek 
0.43-0.50 as high as eye, with numerous fine setulae not 
reduced to single series anteriorly; face with very slightly
