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 />

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 />
