Bembidion (Zeactedium) orbiferum Bates, 1878 View in CoL
Fig. 21 View Figures 21–24 , 54 View Figures 53–60 , 92 View Figures 89–94
Bembidium orbiferum Bates, 1878b: 24 . Type locality: West Coast, South Island.
Other synonymy as in Larochelle and Larivière (2001: 81).
Description. Body length 6.0– 7.3 mm. Black; apex of elytra with a yellowish oblique subapical marking; antennae and legs yellowish (antennal segments 4–11 infuscated). Microsculpture feeble, irregularly isodiametric on head, consisting of confluent transverse lines on pronotum, irregularly isodiametric to slightly transverse with a tendency to form transverse meshes on elytra; microsculpture stronger in female. Moderately shiny (elytra dull in female), with metallic lustre (aeneous, greenish, bluish). Head. Antennae very long (reaching about basal third of elytra). Thorax. Pronotum strongly convex; sides strongly rounded, strongly sinuate posteriorly; basal constriction very short; posterolateral angles acute, strongly projected laterally, rather sharp at tip; laterobasal foveae very deep, linear, short, not reaching basal margin. Elytra. Strongly convex. Sides slightly rounded about middle. Striae deep, becoming shallower apically, coarsely punctate; stria 7 strong, coarsely punctate. Apical striole deep, connected to stria 7. Aedeagus. Lateral view ( Fig. 54 View Figures 53–60 ): moderately arcuate, strongly widened in apical half; base strongly convex dorsally; middle strongly convex dorsally, slightly convex ventrally, with dorsal membranous area wide and moderately long; apex subtriangular, slightly convex dorsally, moderately concave ventrally, with extreme tip moderately wide and long.
Material examined. 31 specimens ( NZAC).
Geographic distribution ( Fig. 92 View Figures 89–94 ). South Island: BR, FD, MK, NN, OL, WD.
Ecology. Lowland, montane. Fossorial. River banks and beds, at a certain distance (2–7 m) from water. Open ground; moist, soft, sandy (yellow), bare or sparsely vegetated soil. Nocturnal; hides during the day in the sand and under well embedded stones.
Gregarious.
Biology. Seasonality: September, December–March. Tenerals: December–March. One specimen 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. Pouring water over the ground; treading the soil with the feet; turning stones.

Remark. Lindroth (1976) recorded this species from eight localities. Three new South Island localities are added from NN (Tadmor River Bridge) and WD (Junction Littleman River and Highway 6; Karangarua River, between Rough Creek and Highway 6).
