( Figs 1D , 2D , 5D , 12 , 13 )

Etheophanus pinguis Broun, 1893: 1233 . Type locality: Mount Pirongia, Waikato.

Diagnosis. Dorsal surfaces rugose or weakly punctate, alveolate microsculpture not distinct. Pronotal vibrissae present. Procoxa without semi-lamellate process, primary dorsal setae decumbent. Eighth sternite of male with each sclerite bearing ca. 4–5 setae along apical margins; spiculum relictum slender. Aedeagus with setae present to basal 1/3 of parameroid lobes; median lobe in dorsal view not narrowing to apex and subrounded apically with serrate edges, in lateral view narrow and elongate and strongly curved ventrally near apex; apico-lateral margin of median lobe bearing 2 setae at each corner. Female tergite VIII apically subrounded; eighth sternite with arms of base strongly arcuate, multisetose to basal 2/3. Gonostylus with 4 apical setae. Spermatheca falciform without globular base.

Comments. Broun based the description on four specimens, one that we designated as the lectotype to stabilise the epithet, and the three remaining designated as paralectotypes.
