Oecetis cymula Neboiss

Figures 41–43, 114

Oecetis cymula Neboiss, 1982: 323 , figs 132–136.

Material examined. WA: 3 paratype males, same data as for holotype ( ANIC); paratypes, females, same locality as holotype, 22 Nov 1978, A. Neboiss ( ANIC) ; males, females, 15 miles NW of Walpole , 15 Nov 1958, E.F. Riek ( ANIC) ; males, females, Harvey River nr Harvey Falls, 15 km E of Harvey, 33°5.5'S 116°2.0'E, 21 Nov 1978, A. Neboiss ( ANIC) .

Diagnosis. Forewing length almost 5 times maximum width, footstalk on fork 1 about half as long as the fork, long downy hairs along wing veins, and t2 more distal than t1 and t3. In male genitalia (Figs 41–43), ventral view, tergum X tapers to an attenuate apex; length of median process of tergum X exceeds length of preanal appendages and inferior appendages are well separated mesially, thus lacking (when viewed laterally) an expanded ventral projection near the base. Females have on each side on segment VIII an area of bristle-like setae.

Distribution. South-western WA (Fig. 114)

Remarks. Oecetis cymula closely resembles O. paracymula but has a tibial spur count of 1, 2, 2, whereas the latter has 0, 2, 2, and O. cymula has fine setae apically and on the mesial margin on the inferior appendages whereas O. paracymula has shorter, stout almost peg-like setae.
