Key to Kiwisaldula species (North Island and nearby offshore islands)

Remark. Additional helpful but not necessarily exclusive characters are provided between square brackets.

1 Antennal segment II short, less than 1.5x longer than segment I. Lateral margins of pronotum narrowly pale or almost completely dark. Hemelytra ( Figs 9 , 17 ) velvety dark brown to bluish black in appearance with extensive steely blue-grey pruinose areas and reduced pale markings, without a nearly uninterrupted pale band along the costal margin. Hind femora darkly pigmented; ventral and dorsal sides dark brown to black, often coalesced into a broad annulus. Male paramere ( Fig. 21 ) without

distinct processus sensualis; processus hamatus rather short, distinctly upturned at tip. [ Small , 2.80–3.32 mm. Brachypterous , with three or four distinctly reduced cells in hemelytral membrane. Distribution : North Island , Central Volcanic Plateau and vicinity.].................................................................. K. stoneri (Drake & Hoberlandt) - Antennal segment II longer, at least 2x longer than segment I. Lateral margins of pronotum broadly pale. Hemelytra ( Figs 10– 12 , 18–20 ) not velvety dark brown to bluish black in appearance, lacking extensive steely blue-grey pruinose areas, with moderately to well developed pale markings and a nearly uninterrupted pale band along the costal margin. Hind femora paler; with or without ventral side partly dark, without a broad annulus. Male paramere ( Figs 22–24 ) with or without processus sensualis; processus hamatus longer, not distinctly upturned at tip...................................................... 2

2 Elongate-ovate species ( Fig. 10 ). Mostly macropterous, cell 4 of hemelytral membrane ending more or less in line with cell 3. Head, pronotum and scutellum slightly shiny, not or barely contrasting against mostly dull hemelytra. Male paramere ( Fig. 22 ) with barely distinct processus sensualis; processus hamatus moderately long and rather broad. Female venter narrowly margined with pale (pale margin often reduced to individual patches laterally on segments). [Larger, about 4 mm long on average. Fore and mid femora often with ventral dark stripe over most of length. Distribution: North Island, central eastern and southern areas.]........................................................................ K. porangahau new species

- Short-ovate species ( Figs 11–12 ). Mostly subbrachypterous, cell 4 of hemelytral membrane ending apically before tip of cell 3. Head, pronotum and scutellum strongly shiny, contrasting against mostly dull hemelytra. Male paramere ( Figs 23–24 ) with or without barely distinct processus sensualis; processus hamatus long or short, narrower than above. Female venter moderately to broadly margined with pale, at least basally. [Smaller, under 3.4 mm long on average.]............................ 3

3 Corium ( Fig. 19 ): costal margin lined with rather wide pale band; basal pale spot of clavus usually absent. Inner margins of male parandria ( Fig. 27 ) almost straight subbasally, slightly concave subapically. Male paramere ( Fig. 23 ) without trace of a processus sensualis; processus hamatus rather long, its tip moderately broad. [Distribution: North Island, northern half and southwestern areas.]................................................................... K. parvula (Cobben)

- Corium ( Fig. 20 ): costal margin lined with rather narrow pale band; basal pale spot of clavus usually present. Inner margins of male parandria ( Fig. 28 ) more sinuate. Male paramere ( Fig. 24 ) with barely distinct processus sensualis; processus hamatus rather short, its tip narrow. [Distribution: Three Kings Islands.]......................... K. manawatawhi new species
