Fauna of New Zealand 69 67
punctures. Intervals depressed, becoming slightly convex
apically. Sutural apices angular-rounded. Abdomen.
Sterna impunctate, unwrinkled. Last visible sternum
(sternum VII): male with four apical ambulatory setae;
female with four apical and two medial ambulatory setae.
Aedeagus. Lateral view (Fig. 79): slightly arcuate; apex
moderately wide, rounded, strongly projecting ventrally,
without a posteroventral tooth-like prolongation. Dorsal
view: asymmetrical (ostium deflected to the right); apex
deflected and twisted strongly to the left. Parameres. Left
paramere setulose (with a few short setae at apex); right
paramere setulose (with numerous short ventral setae in
apical half).
Material examined. 15 specimens (BMNH, CMNH,
JNNZ, NZAC).
Geographic distribution (Map p. 183). South Island:
BR─Mount Robert. NN─Canaan (Takaka Hill). Matiri
Tops. Mount Arthur (Flora Track, Tableland). Mount
Domett. Turk’s Cap (west of Mount Owen). Wangapeka
(Patriarch Creek).
Ecology. Lowland, montane, subalpine, alpine. Wet forests
(beech) and alpine meadows. Shaded (mostly) or open
ground; wet soil. Nocturnal; hides during the day under
stones. This species is primarily epigean (living on the
surface of the ground).
Biology. Seasonality: September, November–December,
February–March. Tenerals: September. Predacious (based
on mouthpart morphology). Occasionally infested with
fungi (Laboulbeniales).
Dispersal power. Elytra fused basally along suture.
Subapterous. Moderate runner. Vagility limited by flight
incapacity.
Reference. Larochelle & Larivière, 2001: 68 (biology,
dispersal power, ecology, geographic distribution).
Remarks. Trichopsida robusta and T. maudensis are
externally similar. See also remarks under T. maudensis.

Description. Body: length 6.7–8.4 mm. Head, pronotum,
and elytra black; lateral margins and apex of elytra yel-
lowish red; abdomen black; antennae, palpi, and legs
entirely pale red. Microsculpture strong and isodiametric.
Iridescence absent. Dull (as T. robusta). Head. Impunctate
dorsally, wrinkled on frons, slightly narrower across eyes
than pronotal apex. Mandibles short. Labrum moderately
transverse, slightly emarginate anteriorly. Antennae: segment
1 (scape) moderately long, about 2× longer than its
maximum width; segments 1–3 glabrous (excluding apical
setae). Frontal furrows wide, shallow. Eyes normally
developed, moderately large and convex. Tempora oblique,
moderately long (about half as long as eyes). Mentum:
medial tooth acute apically, slightly shorter than lateral
lobes. Ligula wide apically. Paraglossae membranous,
prominent, much longer than ligula. Palpi: terminal segment
fusiform, not elliptical, sparsely setulose; penultimate
maxillary segment apically setulose. Thorax. Pronotum
(Fig. 126) moderately convex, coarsely punctate and
feebly wrinkled across base, strongly transverse, strongly
cordate; apex strongly arcuate; anterolateral angles moderately
developed, obtuse; sides strongly rounded anteriorly,
strongly sinuate posteriorly; lateral beads narrow; lateral
depressions absent; a single setiferous puncture on each
side (anteriorly), about middle and not touching lateral
bead; posterolateral angles subrectangular, not denticulate;
laterobasal foveae well defined, coarsely punctate, deep,
wide, elongate anteriorly; posterior bead complete; base
emarginate medially, slightly oblique laterally, moderately
narrower than apex, much narrower than elytral base.
Prosternum impunctate, unwrinkled. Proepisterna impunctate,
unwrinkled. Metepisterna impunctate. Elytra.
Moderately convex, ovate, widest about middle. Basal
margin complete. Shoulders rounded, denticulate. Sides
strongly rounded. Scutellar setiferous pore inserted at base
of stria 1. Scutellar striole impunctate. Striae complete,
moderately deep, impunctate; stria 3 with four setiferous
punctures. Intervals depressed, becoming slightly convex
apically. Sutural apices angular-rounded. Abdomen.
Sterna impunctate, unwrinkled. Last visible sternum
(sternum VII): male with four apical ambulatory setae;
female with four apical and four medial ambulatory setae.
Aedeagus. Lateral view (Fig. 80): moderately arcuate;
apex moderately wide, rounded, strongly projecting ventrally,
with a posteroventral tooth-like prolongation. Dorsal
view: asymmetrical (ostium deflected to the right); apex
strongly deflected and twisted to the left (as in T. robusta).
Parameres. Left paramere setulose (with a few short setae
at apex); right paramere setulose (with numerous short
ventral setae in apical half).
Material examined. Three specimens (NZAC).
