Oecetis umbra Neboiss, 1977: 144 , figs 770–773. — Neboiss, 1986: 268.

Holotype. Male , Tas., Waldheim, Cradle Mountain National Park ( NMV T-5489).

Material examined. Tas. : 1 male, Lake Dobson, 20 Feb 1967, E.F. Riek ( ANIC) ; numerous males, females, Franklin R., Roaring Creek junction, 1 km above Gordon R., 8 Jan 1977, Coleman, Neboiss, Allbrook ( NMV) ; 1 male, Gordon R., 1 km above First Split , 11 Jan 1977, Coleman, Neboiss, Allbrook, Swain ( NMV) ; 2 males, 1 female, swamp near Olga R., 19 km above Gordon R. Junction, 13 Jan 1977, Neboiss and Swain ( NMV) ; 2 males, 2 females, Caves Camp , NE of New R. Lagoon, 2 Jan 1979, S.F. McEvey ( NMV) ; numerous males, females, south coast, Cavers Camp , New R. Lagoon, 3 Jan 1979, S.F. McEvey ( NMV) .

Diagnosis. Male. Closely resembling O. pechana and O. walpolica in general features such as scales on the wing and clasper-shaped inferior appendages, but distinguished from both these species by shorter phallus with the paramere only slightly curved, and inferior appendages divergent apically, rather than convergent.

Distribution. Known only from Tas.

Remarks. Neboiss, 1977 compared this species to the New Zealand Oecetis unicolor McLachlan and Chatham I. O. chathamensis Tillyard and it certainly resembles those species more closely than it does Australian species.
