description: Etheophanus striatus Broun, 1910
(Figs 1E, 2E, 5E, 14, 15)
Etheophanus striatus Broun, 1910: 69. Type locality: Waimarino. Etheophanus punctiventris Broun, 1914: 231. Type locality: Mount Hutt and McClennan's Bush, near Methven. New Synonymy.
Diagnosis. Dorsal surfaces coarsely punctate, alveolate microsculpture indistinct. Pronotal vibrissae usually absent (short and present in some specimens). Procoxa without semi-lamellate process, primary dorsal setae decumbent. Eighth sternite of male with each sclerite bearing ca. 4 setae along apical margins; spiculum relictum broad. Aedeagus with setae present to basal 1/3 of parameroid lobes; median lobe in dorsal view not narrowing to apex and subrounded apically with simple edges, in lateral view broad and not strongly curved ventrally near apex; apico-lateral margin of median lobe bearing 1 seta at each corner. Female tergite VIII apically subrounded; eighth sternite with arms of base strongly arcuate, multisetose to basal 2/3 or 1/2. Gonostylus with 3 apical setae. Spermatheca falciform and recurved without globular base.
Comments. Broun based the description of E. striatus on two specimens, one that we designated as the lectotype to stabilise the epithet, and the other, noted by Broun as a sexual variant, was designated as a paralectotype. While the type locality of E. striatus is in the southern half of the North Island, Broun (1914) later described E. punctiventris from Canterbury. Despite the geographic distance separating the type localities, the specimens are morphologically similar and falling within the geographic variation of the species and therefore conspecific and considered as synonymns. Broun based the description of E. punctiventris on three specimens, one that we designated as the lectotype to stabilise the epithet, and the two remaining were designated as paralectotypes.
