Fig. 40 , 83 , 156

Anchomenus Feredayi Bates, 1874: 240 (redescribed 1875: 303). Lectotype (here designated): male (MNHN) labeled “[MC] Christchurch N. Zeal. (hand-written) / Anchom. Feredayi Bates (hand-written) / LECTOTYPE [male symbol] Anchomenus feredayi Bates, 1874 designated by Larochelle & Larivière, 2021 (red label; typed).”

Agonum (Europhilus) feredayi: Csiki 1931: 869 .

Description. Body length 7.3–8.4 mm. Head, pronotum, and elytra mostly black; abdomen black; antennae black (base of segments reddish); palpi black, except apical third of terminal segment reddish; legs black. Microsculpture isodiametric on head, very transverse (with microlines) on pronotum, and isodiametric on elytra. Iridescence present on pronotum. Very shiny; metallic luster (bronze) moderate on head and pronotum, strong on elytra. Head. Mandibles moderately curved anteriorly. Labrum moderately transverse, subtruncate anteriorly. Thorax. Pronotum moderately convex, impunctate, feebly wrinkled on disc and mediobasally, very wide, rectangular, widest about middle; apex slightly emarginate; anterolateral angles poorly developed, rounded; anterior bead complete; sides strongly rounded, not sinuate posteriorly; lateral beads complete; lateral depressions narrow anteriorly, gradually widened posteriorly; posterolateral angles obtuse; laterobasal foveae very deep, moderately wide, prolonged forward; posterior bead incomplete, obsolete medially; base subtruncate. Legs. Moderately long. Metatarsomeres 5 glabrous ventrally. Elytra. Moderately convex, sloping down toward apex, oblong. Free along suture (hindwings fully developed). Shoulders broad, strongly rounded. Sides slightly rounded. Scutellar striole finely punctate (impunctate in other species). Striae shallow, finely punctate (impunctate in other species). Intervals depressed; interval 3 with three shallow, minute setiferous punctures. Umbilicate series with 15–16 setiferous punctures. Subapical sinuations strong (feeble in other species). Aedeagus. Lateral view ( Fig. 83 ): moderately arcuate; base moderately convex dorsally, with basal lobe very wide; middle moderately convex dorsally, moderately concave ventrally, with narrow dorsal membranous area; apex slender, slightly concave dorsally, slightly concave ventrally, with extreme tip narrow and moderately long.

Material examined. 1088 specimens ( AMNZ, CMNH, CMNZ, JNNZ, LUNZ, MNHN, MONZ, NZAC).

Geographic distribution ( Fig. 156 ). South Island: BR, CO, DN, FD, KA, MB, MC, MK, NC, NN, OL, SC, SD, SL, WD. Stewart Island.

Ecology. Lowland, montane, subalpine, alpine. Epigean, planticolous. Edges of streams, rills, seepages, lakes, ponds, and tarns; boggy pastures, swamps, wet tussock grasslands, and alpine meadows. Mostly open ground; wet soil. Nocturnal; hides during the day under logs and stones. Gregarious.

Biology. Seasonality: September–May, July–August. Tenerals: October–February. Predacious (based on mouthpart morphology). Occasionally infested with fungi (Laboulbeniales).

Dispersal power. Macropterous, probably capable of flight. Moderate runner. Regular climber (on trees and plants).

Collecting techniques. Turning logs and stones; pitfall trapping.

Remarks. Bates described Anchomenus feredayi from two specimens, one of which (a male) could be seen (MNHN) and is here designated as lectotype. This type designation is made to preserve stability of nomenclature in the future.
