 Bembidion (Zemetallina) urewerense Lindroth, 1976: 191. Type locality: Lake Waikaremoana, Urewera National Park, GB.   
 Description. Body length 3.2–4.1 mm. Black; antennae pale rufous (segments 5–11 infuscated); legs rufous. Microsculpture in both sexes, absent or almost so on disc of head and pronotum, slightly more visible laterally; elytra in male, with isodiametric microsculpture basally and laterally; elytra in female, with feeble isodiametric microsculpture over entire surface. Very shiny, without metallic lustre. Forebody moderately wide in comparison to elytra. Head. Antennae filiform, moderately long (reaching about elytral shoulders). Thorax. Pronotum strongly convex, very wide; sides strongly rounded anteriorly, strongly sinuate posteriorly (more sinuate than in other Zemetallina species); posterolateral angles acute, moderately projected laterally; laterobasal foveae shallow, obsolete, not reaching basal margin. Epipleura (in dorsal view) exposed in front of posterolateral angles. Elytra. Moderately convex, subovate, moderately wide, widest about middle. Shoulders moderately rounded. Sides moderately rounded. Scutellar striole consisting of a line and punctures. Striae 2–3 complete, 4–6 incomplete; striae shallow (deepening apically), coarsely punctate; stria 7 strong, incomplete, coarsely punctate. Intervals depressed or subdepressed. Apical striole deep, connected to stria 5 or 7; preapical setiferous puncture not isolated. Abdomen. Last visible sternum (sternum VII) of female with numerous short setae in addition to four long ambulatory setae. Aedeagus. Lateral view (Fig. 63): strongly arcuate, wide medially; base moderately convex dorsally; middle strongly convex dorsally, slightly concave ventrally; apex narrow, rather straight dorsally and ventrally, with extreme tip rather narrow and short.   
 Material examined. 138 specimens (NZAC).   
 Geographic distribution (Fig. 103). North Island: BP, GB, HB, RI, TK, WA, WI.   
 Ecology. Lowland, montane. Epigean. Edges of trickles, seepages, puddles, flats along roadsides and rivers, as well as stream banks, at a certain distance (3–15 m) from water.   
 Open ground; wet, usually sandy, sometimes clay, bare or sparsely vegetated soil. Nocturnal; hides during the day at the base of plants (e.g., Juncus), under fallen leaves and plant debris, as well as in moss, under stones and soil clods. Gregarious.   
 Biology. Seasonality: September, November–January, March, May–June. Tenerals: December–January. Occasionally infested with fungi (Laboulbeniales). Defence mechanism: when alarmed, the adult escapes by running.   
 Dispersal power. Macropterous, probably capable of flight. Moderate runner. Vagility likely favoured by flight capacity.   
 Collecting techniques. Turning plant leaves and debris, stones and soil clods.   
 Reference. Larochelle and Larivière 2001: 83 (catalogue; biology, dispersal power, ecology, geographic distribution, reference).   
 Remark. Lindroth (1976) recorded only four localities for this species; it is now known from many localities in the southern half of the North Island.
