Type locality: Mount Alfred. Etheophanus obscurus Broun, 1923 : 701 . Type locality: Harris Saddle, southwest Otago . New Synonymy. Diagnosis. Dorsal surfaces apunctate, alveolate microsculpture present, primary dorsal setae adpressed. Pronotal vibrissae present. Procoxa without semi-lamellate process. Eighth sternite of male with each sclerite bearing ca. 6 or 7 setae along apical margins; spiculum relictum slender. Aedeagus with setae present at apex of parameroid lobes; median lobe in dorsal view narrowing to subrounded, and slightly blunted apex with simple edges, in lateral view narrow and elongate and strongly curved ventrally near apex; apico-lateral margin of median lobe bearing a bundle of ca. 6 setae at each corner. Female tergite VIII apically subrounded; eighth sternite with arms of base parallel-sided, apices with 6–7 setae. Gonostylus with 5 apical setae. Spermatheca falciform without globular base.

FIGURES 9A–D. Etheophanus nitidellus , female terminalia. A, sternite VIII; B, tergite VIII; C, gonocoxites; D, spermatheca. Comments. Broun based the description of E. nitidellus on a single specimen that we confirmed as the holotype collected from Mount Alfred located north of Glenorchy. Immediately following this description, Broun described a second species from Harris Saddle, also located north of Glenorchy, that we we confirmed as the holotype of E. obscurus , and with the comment “this obscurely coloured species is separable by the elytral sculpture.” The differences among the specimens are well within the range of variation present in E. nitidellus and we consider the two as synonymns.
