Bembidion (Zemetallina) solitarium Lindroth, 1976: 185 View in CoL . Type locality: Rangitikei River flats, RI.

Description. Body length 4.4–5.2 mm. Black; antennae with segments 1 and 4–11, and underside of segments 2–3 rufous; femora brown, tibiae and tarsi yellowish. Microsculpture moderately transverse, feeble on disc of head and pronotum, and moderately strong on elytra. Shiny, with strong metallic lustre (greenish aeneous). Forebody moderately wide in comparison to elytra. Head. Antennae filiform, moderately long (reaching about elytral shoulders). Thorax. Pronotum strongly convex, moderately wide; sides strongly rounded anteriorly, moderately sinuate posteriorly; posterolateral angles subrectangular, vaguely obtuse at tip; laterobasal foveae moderately deep, linear, moderately long, reaching basal margin or almost so. Epipleura (in dorsal view) not exposed in front of posterolateral angles. Elytra. Moderately convex, subovate, moderately wide, widest about middle. Shoulders and sides moderately rounded. Scutellar striole consisting of a row of punctures. Striae incomplete (striae 4–6 abbreviated apically), moderately deep, coarsely punctate; stria 7 strong, incomplete, coarsely punctate. Intervals depressed. Apical striole moderately deep, connected to stria 7; preapical setiferous puncture not isolated. Abdomen. Last visible sternum (sternum VII) of female with four long ambulatory setae only. Aedeagus. Lateral view ( Fig. 65 View Figures 61–69 ): moderately arcuate; base slightly concave dorsally; middle strongly convex dorsally, strongly concave ventrally; apex moderately wide, with extreme tip subtriangular and moderately long.

Material examined. 54 specimens ( JNNZ, NZAC).

Geographic distribution ( Fig. 96 View Figures 95–100 ). North Island: HB, RI, WA, WI, WN.

Ecology. Lowland. Epigean. River banks, at a certain distance (1–5 m) from water. Open ground; wet, sandy bare soil sometimes mixed with loam or clay. Nocturnal; hides during the day under stones. Semi-gregarious.

Biology. Seasonality: September–October, December–January, April, July. Tenerals: December. Occasionally infested with fungi (Laboulbeniales). Defence mechanism: when alarmed, the adult escapes by running.

Dispersal power. Macropterous, probably capable of flight. Fast runner. Occasional flier. Vagility favoured by flight capacity.

Collecting techniques. Turning stones; pouring water over the ground.

Reference. Larochelle and Larivière 2001: 82 (catalogue; biology, dispersal power, ecology, geographic distribution, references).

Remark. The distribution of this species was somewhat poorly known before this revision. It currently includes many North Island localities. The South Island record from Buller (BR), given by Townsend (1997) and subsequently by Larochelle and Larivière (2001), refers to B. bullerense .
