Sinclair: Hydropeza empidid flies of Australia 
9 
Figures 19-20. Known distribution of the Hydropeza species: (19) H. divaricata sp. nov. (•) and (20) H. intricata sp. nov. (♦). Shaded 
areas indicate land above 700 m in altitude. 
of posterior margin overlapping more than half length of 
following tergite. T8 broad, nearly one-half length of T7; 
posterior marginal setae slender, some 1.5* length of tergite. 
Terminalia (Fig. 9). Cercus projected horizontally, shorter 
than epandrium, not forked or subdivided; apex sharply bent 
at right angle medially, nearly touching opposing cercus. 
Epandrium broad with scattered setae. Surstylus short, 
with broadly rounded apex, not arched medially; inner 
margin with cluster of some 8 stout setae. Hypandrium 
subrectangular broad; apical margin not notched; gonocoxal 
apodeme broad, rounded; postgonite broad, short and 
L-shaped, touching opposing postgonite medially. Phallus 
broad with apex inflated; ejaculatory apodeme straight, 
longer than gonocoxal apodeme. 
Female. Similar to male except as follows: scutellum 
with 1 pair of discal setae; mid femur lacking row of stout 
posteroventral basal setae; mid tibia not narrowed apically, 
lacking row spine-like setae; hind femur not strongly inflated, 
lacking anteroventral row of stout setae. Terminalia (not 
dissected): segment 8 not inflated, broad; cercus slightly 
longer than epiproct, nearly 2x longer than wide; broad 
with rounded apex. 
Distribution. This species is recorded from above 800 m on 
Mt. Lewis, Queensland (Fig. 7). 
Etymology. The specific name is from the Latin angulatus 
(with angles), in reference to the right angle bend of the 
male cercus.
