Description 
Male. Unknown. 
Female. Body length 4.8 mm. Bristles black. First 
flagellomere orbicular. Arista pubescent. Vibrissa relatively 
long and curved. Ocellar bristle approximately as long as 
postvertical. Two dorsocentral bristles. Gena relatively 
high and bent medially. Face and buccal cavity meeting at 
an angle. Head mostly yellow, sometimes with brownish- 
golden tint; first flagellomere brownish-orange; ocellar 
tubercle brown; frons golden-orange centrally; back of head 
with one pair of faded stripes radiating from foramen; upper 
half of gena silvery tomentose. Fore tarsi ovate in cross 
section. Scutum yellow with central spindle-shaped stripe 
and one pair of small faint spots at suture. Scutellum yellow. 
Laterotergites brownish laterally. Pleuron yellow with dorsal 
Vi of anepistemum dark brown, anepimeron brown, dorsal 
margin of katepistemum faded brown and meron light brown. 
Legs yellow with fore tarsi brown (first segment and base 
of second segment yellow), fore tibia with faint sub-basal 
band and fore femur with faint subapical band. Abdomen 
dark brown with segment 10 yellow. M 1+2 ratio 5.1. Wing 
with faint anterodistal infuscation and light cloud around 
distal Vi of R 4+5 (indistinct in one specimen). Halter white. 
Female terminalia (Fig. 100). Sides of tergite 8 meeting at 
Vi length ventrally. Ventral receptacle thin and cylindrical; 
flagellum long and straight. Spermatheca longer than wide 
and with minute basal wrinkles; apex broadly rounded and 
invagination small and slightly offset. 
Etymology. The specific name is derived from the Greek for 
slug {Umax), describing the shape of the notal stripe.

Description 
Male. Body length 2.8 mm. Anepisternal disc present. 
First flagellomere orbicular. Bristles black. Arista closely 
pubescent. Vibrissa relatively long and curved. Ocellar bristle 
thin and longer than tubercle. Two dorsocentral bristles with 
small bristle in front of anterior dorsocentral. Gena shallow 
and not strongly angled or bent. Face and buccal cavity 
pilose and meeting at an angle. Frons brown on posterior 
half and along lateral margins of anterior half; anterior Vs 
of frons tomentose; clypeus brown; occiput, back of head, 
ventral and posterior margins of gena and palpus dark brown; 
lateral margin of face with thin brown line; first flagellomere 
with anterior margin and distal Vi of inner face brown; gena 
pilose. Thorax dark brown. Legs yellow with fore tarsi, fore 
tibia and apex of fore femur dark brown. Fore tarsi slightly 
compressed laterally. Abdomen brown. M 1+2 ratio 9.0. Wing 
dusky. Halter brown with distal surface white. 
Female. As described for male except frons entirely dark, gena 
more darkly pigmented and face and parafacial dark brown. 
Male terminalia (Figs 50-53). Epandrium with length 
shorter than height and slightly more than half width. 
Surstylus higher than wide with sides parallel, apex pointed 
and inner face with two or three apical tubercle-like bristles. 
Cerci setose medially and apically, sides nearly parallel 
and apex emarginate. Hypandrium+pregonite with two 
small diverging lobes; posterior lobe truncated and setulose 
apically; anterior lobe with two stout apical bristles and 
ventral margin contiguous with single raised row of setulae 
continuing along lateral surface. Distiphallus with one rib 
ending medially and one rib trifid on distal half with several 
lateral spines. 
Female terminalia (Fig. 101). Stemite and tergite 8 entirely 
fused with small posteromedial emargination ventrally. 
Spermatheca barrel-shaped and invaginated apically. Ventral 
receptacle curved and with subterminal flagellum straight 
and long. 
Etymology. As several of the types were collected at 
Kangaroo River, the specific name is derived from the genus 
name for terrestrial kangaroos {Macropus).
