moderately projecting ventrally. Dorsal view: asymmetrical<br />

(ostium deflected to the right); apex deflected to the<br />

left. Parameres. Glabrous.<br />

Material examined. 18 specimens (AMNZ, BMNH,<br />

CMNZ, JNNZ, LUNZ, NZAC).<br />

Geographic distribution (Map p. 181). South Island:<br />

MC–Cass. Lake Sumner. NC–Arthur’s Pass (Coral Creek,<br />

Mount Aicken, Temple Basin), Bealey. OL–Clipping’s<br />

Bush (near Kingston). WD–Upper Otira Valley.<br />

Ecology. Lowland, montane, subalpine. Forests (beech,<br />

podocarp) and scrublands. Shaded ground. Nocturnal;<br />

hides during the day in leaf litter, under stones, and in<br />

moss growing on tree–trunks. The body shape (poorlydeveloped<br />

eyes, inflated tempora, depressed elytra) and<br />

pale colour suggest that the species is endogean (living<br />

in soil crevices or fissures, in deep humus <strong>of</strong> leaf litter,<br />

under well-embedded stones).<br />

Biology. Seasonality: October to December, February.<br />

Predacious (based on mouthpart morphology). Occasionally<br />

infested by fungi (Laboulbeniales).<br />

Dispersal power. Elytra fused basally along suture. Subapterous.<br />

Moderate runner. Occasional climber (on trees).<br />

Vagility limited by flight incapacity.<br />

Reference. Larochelle & Larivière, 2001: 67 (biology,<br />

dispersal power, ecology, geographic distribution).<br />

Remarks. Examination <strong>of</strong> the holotype <strong>of</strong> Tarastethus<br />

longulus revealed it to be conspecific with Trichopsida<br />

debilis. This is the only species <strong>of</strong> Trichopsida with the<br />

pronotum strongly wrinkled and punctate throughout.<br />

Trichopsida propinqua (Broun, 1917) E new<br />

combination<br />

Description. Body: length 4.7–6.6 mm. Head, pronotum,<br />

and elytra black (forebody sometimes reddish black);<br />

abdomen reddish black; antennae, palpi, and legs entirely<br />

pale red. Microsculpture very transverse (with microlines),<br />

feeble on head and pronotum, strong on elytra. Iridescence<br />

Larochelle & Larivière (2013): Carabidae (Insecta: Coleoptera)<br />

absent. Very shiny. Head. Impunctate and unwrinkled<br />

dorsally, much narrower across eyes than pronotal apex.<br />

Mandibles very long. Labrum moderately transverse<br />

and emarginate anteriorly. Antennae: segment 1 (scape)<br />

moderately long, about 1.5× longer than its maximum<br />

width; segments 1–3 glabrous (excluding apical setae).<br />

Frontal furrows wide, deep. Eyes reduced, moderately<br />

small, slightly convex. Tempora convex, moderately long<br />

(about two-thirds as long as eyes). Mentum: medial tooth<br />

acute apically, slightly shorter than lateral lobes. Ligula<br />

narrow apically. Paraglossae membranous, prominent,<br />

much longer than ligula. Palpi: terminal segment fusiform,<br />

not elliptical, sparsely setulose; penultimate maxillary<br />

segment sparsely setulose. Thorax. Pronotum (Fig. 139)<br />

moderately convex, impunctate or punctate across posterior<br />

bead, wrinkled along median longitudinal impression<br />

and between laterobasal foveae, quadrate, moderately<br />

cordate; apex slightly arcuate; anterolateral angles (in<br />

lateral view) poorly developed, obtusely rounded; sides<br />

strongly rounded anteriorly, not sinuate posteriorly; lateral<br />

beads narrow; lateral depressions absent; two setiferous<br />

punctures on each side; each anterolateral setiferous puncture<br />

situated well in front <strong>of</strong> middle and touching lateral<br />

bead; posterolateral angles acute, denticulate; laterobasal<br />

foveae absent; posterior bead interrupted medially; base<br />

emarginate medially, slightly oblique laterally, about as<br />

wide as apex, much narrower than elytral base. Prosternum<br />

impunctate, unwrinkled. Proepisterna impunctate, unwrinkled.<br />

Metepisterna impunctate. Elytra. Depressed dorsally,<br />

slightly convex laterally, subelongate, widest about middle.<br />

Basal margin complete. Shoulders obtuse, denticulate.<br />

Sides slightly rounded. Scutellar setiferous pore absent.<br />

Scutellar striole bipunctate. Striae mostly complete<br />

(striae 6–7 obsolete), shallow, indistinctly punctate;<br />

stria 3 without setiferous punctures. Intervals depressed.<br />

Sutural apices angular. Abdomen. Sterna impunctate,<br />

unwrinkled. Last visible sternum (sternum VII): male with<br />

four apical ambulatory setae; female with four or six apical<br />

and two medial ambulatory setae. Aedeagus. Lateral<br />

view (Fig. 91): strongly arcuate; apex moderately wide,<br />

subtriangular-rounded, moderately projecting ventrally.<br />

Dorsal view: asymmetrical (ostium deflected to the right);<br />

apex deflected to the left. Parameres. Setulose (with a few<br />

short setae at apex).<br />

Material examined. 67 specimens (AMNZ, BMNH,<br />

CMNZ, JNNZ, LUNZ, NZAC).<br />

Geographic distribution (Map p. 183). South Island: CO,<br />

DN, FD, OL, SL, WD.<br />

Ecology. Lowland, montane, subalpine, alpine. Forests<br />

(beech, broadleaf, podocarp), shrublands, scrublands, and<br />

alpine meadows. Shaded (mostly) or open ground; wet<br />

soil. Nocturnal; hides during the day in the soil, deep leaf
