variously lengthened and thickened spine-like setae, mostly 
concentrated apically and mid-basally; basal most seta longer

seta at basal third; 1 long preapical posterior seta. Fore tibia

posterior setae; apical fifth with 1 dorsal and 2 posterodorsal 
setae; 1 antero ventral and 1 anterodorsal preapical seta. Fore 
tarsomere 1 with 1 dorsal and 1 anterodorsal near mid-length; 
1 ventral seta on basal fourth; apex with 1 anterodorsal and 
1 posterodorsal seta. Mid femur with knob-like process at 
basal third, bearing several short spine-like setae (Fig. 15); 
2 long stout setae proximal to process, longer than width of 
femur (Fig. 16); 3 anterodorsal and 3 posterodorsal setae 
on distal half; apex with 1 anterodorsal and 1 posterodorsal 
preapical seta. Mid tibia with anteroventral notch on apical 
sixth, with distal row of short spine-like setae terminating in 
pair of claw-like apical setae (Fig. 16); opposite notch with 
sinuous spur-like anterodorsal seta; 2 anterodorsal setae, 4 
posterodorsal setae and 2 anterior setae. Mid tarsomere 1 with 
ventral curve at base, with long anterior seta; 1 anterodorsal, 
1 posterodorsal seta; apex with several preapical stout setae. 
Hind femur with erect dorsal setae; 1 preapical anterior, 2 
preapical anterodorsal and 1 preapical posterodorsal setae 
on apical fourth, longer than width of femur. Hind tibia with 
4-5 anterodorsal and posterodorsal setae; 2 preapical anterior 
setae; 1 anteroventral seta on apical third. Hind tarsomere 1 
with several dorsal and preapical setae. Tarsomeres of fore 
and midlegs much longer than tibia; ventral apical margin 
of tarsomere 4 of fore and midlegs somewhat pale, flattened 
and expanded; tarsomere 4 of hindleg laterally compressed 
ventrally, keel-like, extending beyond apex; tarsomere 5 of 
each leg lacking dorsoapical extension (Fig. 17). 
Wing (Fig. 28). Infuscate with 1 long basal costal seta, 
longer than sctl; all veins lacking setulae; R 4 and R 5 distinctly 
divergent apically, base of R 4 often weakened; bm-m 
complete; cell dm truncate to slightly produced, longer than 
length of cell bm; CuA + CuP present only as short streak. 
Halter brown. 
Abdomen. Tergites and stemites clothed in setae; setae 
of posterior margin overlapping more than half length of 
following tergite. T8 broad, more than half length of T7; 
posterior marginal setae greatly reduced in length compared 
to preceding tergites. 
Terminalia (Figs 26, 27). Cercus divided into two 
components: anterior cercus small, thinly sclerotized sclerite 
surrounding anus, bearing long setae; posterior cercus 
sickle-shaped, heavily sclerotized with peg-like setae along 
posteromedial margin; apex of posterior cercus tapered, 
bearing stout terminal seta. Epandrium small, bilobed with 
longer setae of posterior lobe; lamellae separated dorsally 
beneath cercus by wide membranous gap; epandrium 
not prolonged posteriorly. Surstylus not differentiated. 
Hypandrium keel-like, prolonged dorsally into phallic guide; 
gonocoxal apodeme inconspicuous; long setae on posterior 
half extending to base of dorsal extension; postgonite 
finger-like, slightly curved. Phallus long and filamentous, 
extending anteriorly into abdomen for 2-3 segments, twisted 
into figure-8, emerging from phallic guide of hypandrium; 
ejaculatory apodeme reduced not plate-like. 
Female. Similar to male except as follows: mid femur and 
tibia lacking modified setae and processes. Terminalia (not 
dissected): cercus long and slender with rounded apex. 
Distribution. This species is restricted to Tasmania (Fig. 
22 ), occurring in upland streams and rivers from western, 
northeastern and southern Tasmania. 
Etymology. The specific name refers to the distribution of 
this species, which is widespread in Tasmania. 
Remarks. The shape of the hypandrium and epandrium is 
very similar to H. wardi Sinclair & McLellan from New 
Zealand.

Type material. Holotype Tasmania: “Pelion Tas/ June 
1990/ INaumann”; “HOLOTYPE/ Hydropeza/ unguicula/ 
Sinclair [red label]” (ANIC). 
Diagnosis. This Tasmanian species is recognized by the 
modified male forelegs, especially the claw-like process of 
tarsomere 1 and pointed spatulate process of tarsomere 4 of 
the male midleg. 
Description. Head, thorax and legs dark brown, abdomen 
slightly paler. Wing length 3.8 mm. 
Male. Head. Ocellar setae long, erect, divergent, inserted 
between anterior and posterior ocelli; ocellar tubercle with 
several short setulae; postocellar and postocular setae dark, 
stout to slender; postgenal setae similar to postoculars. Lower 
half of face lacking setulae. Scape long and slender, about 
2 x length of globular pedicel; postpedicel elongate, basal 
portion not broader than pedicel, shorter than slender, tapered 
apical portion; stylus slightly longer than apical portion of
