Bembidion (Zemetallina) tekapoense Broun, 1886 View in CoL Fig. 25 View Figures 25–28 , 58 View Figures 53–60 , 99 View Figures 95–100
Bembidium tekapoense Broun, 1886: 880 . Type locality: Near Lake Tekapo, MK.
Other synonymy as in Larochelle and Larivière (2001: 83).
Description. Body length 4.0– 4.9 mm. Black; antennae and legs piceous (darker than in B. anchonoderus ). Microsculpture very strong, isodiametric. Shiny, with moderately strong metallic lustre (aeneous, sometimes greenish). Forebody narrow in comparison to elytra. Head. Antennae filiform, moderately long (reaching about elytral shoulders). Thorax. Pronotum moderately convex, narrow (compared to other Zemetallina species); sides strongly rounded anteriorly, moderately sinuate posteriorly; posterolateral angles subrectangular, somewhat obtuse at tip; laterobasal foveae, shallow, obsolete, moderately long, not reaching basal margin. Epipleura (in dorsal view) exposed in front of posterolateral angles. Elytra. Subdepressed, oblong-elongate, very wide, widest behind middle. Shoulders angulate. Sides subparallel. Scutellar striole consisting of a row of punctures. Striae 2–6 complete, shallow although well impressed apically, finely punctate (outer striae less impressed than inner ones); stria 7 obsolete, incomplete, finely punctate. Intervals depressed. Apical striole deep, connected to stria 5 or 7; preapical setiferous puncture not isolated. Abdomen. Last visible sternum (sternum VII) of female with four long ambulatory setae only. Aedeagus. Lateral view ( Fig. 58 View Figures 53–60 ): slightly arcuate, almost subparallel; base slightly convex dorsally; middle slightly convex dorsally and ventrally; apex triangular, straight dorsally, slightly concave ventrally, with extreme tip narrow and short.
Material examined. 198 specimens ( CMNH, JNNZ, MONZ, NZAC).
Geographic distribution ( Fig. 99 View Figures 95–100 ). North Island: BP, HB, RI, WA, WI, WN, WO. South Island: BR, CO, KA, MB, MC, MK, NC, NN, OL, WD. Stewart Island.
Ecology. Lowland, montane. Epigean. River banks and bars, at a certain distance (0–1 m) from water. Open ground; wet, sandy bare soil with gravel and scattered stones. Nocturnal; hides during the day under stones and among gravel. Gregarious.
Biology. Seasonality: September–April. Tenerals: February. Occasionally infested with fungi (Laboulbeniales). Defence mechanism: when alarmed, the adult escapes by running.
Dispersal power. Macropterous, probably capable of flight. Fast runner. Vagility likely favoured by flight capacity.
Collecting techniques. Turning stones; raking the soil; pouring water over the ground.
