Description (incrustation removed). Body pear-shaped (more broadly so in female); length about 3.5 mm (male), 3.9 mm (female). Dorsal color (male) dark reddish brown tinged with dark brown approaching black; yellowish brown on plates and markings of lateral margins of pronotum, fused notal plate, tergal plate of abdomen, between connexival segments, and medially on dmtg VII (male). Female darker overall. Eyes reddish brown. Antennae and legs slightly paler than main body. Ventral color mostly matching dorsal color. Head. About 0.8× as long as wide across eyes. Genae slightly to moderately longer than clypeus, forming a gap in front. Antenniferous tubercles broadly subtriangular (inner margin subrectilinear or slightly concave), their apices subacutely rounded and divergent. Postocular tubercles rounded-subquadrate, slightly to moderately produced laterally. Antennae about as long as or barely longer than width of head across eyes, mostly granulate. Ratio of length of antennal segments II–IV/I about 0.5: 0.6: 0.8. Segment I narrowed, smooth in basal fourth, then thickened; II slightly curved basally, gradually thickened toward apex; III pedunculate in basal fourth, gradually thickened toward apex; IV fusiform, pilose in apical fourth to third. Thorax. Pronotum about 3.6–4.0× wider than long medially, including collar. Anterior margin barely incised on each side of collar. Anterolateral angles rounded to subquadrate, slightly produced in front of collar (angles sometimes more strongly angular and produced in female). Disc barely produced posteriorly. Lateral portions with four rather small irregularly shaped plates and, submarginally, a finely granulate to nearly smooth, strongly curved bead extending from anterior to posterior margin. Posterolateral angles rounded-subquadrate, unproduced. Notal plate (fused mesonotum, metanotum, dmtg I–II) moderately elevated posteromedially. Anterolateral portions, each with two large, irregularly shaped pale marks or slightly elevated plates next to a submarginal, granulate, longitudinal bead in line with that of pronotum. Midlateral portions, each with three moderately large, irregularly shaped, pale marks or slightly elevated plates. Posterolateral portions, each with two pairs of small suboval to rounded apodemal spots (a pair in line with transverse suture of dmtg I–II, a second pair more anteriorly). Dmtg I–II, each with a pair of more or less defined longitudinal plates medially (often reduced to pale marks);separated by a short transverse suture not reaching inner apodemal spots. Abdomen widest across tergite IV. Tergal plate (dmtg III–VI). Disc slightly to moderately elevated; dmtg IV–V with reduced or evanescent plate carrying scent gland openings, VI smooth, with slight median elevation but no plate. Lateral margins moderately convex (male), more strongly convex (female). Inner and outer rows of apodemal markings usually made of distinct, suboval to rounded, smooth spots (sometimes evanescent). Dmtg VII broadly smooth medially, very narrowly marked with small callosities and granules laterally, moderately elevated posteromedially (male); smooth throughout, unevenly surfaced, lateral margins subrectilinear, oblique (female). Connexivum carinate between dorsal laterotergites (dltg) and reflexed part of pleuron; increasingly reflexed toward apex (male), rather flat (female). Posterolateral angles of dltg III–VI rounded-subquadrate, barely produced, increasingly reflexed, VII broadly rounded-subtriangular, slightly thickened and produced, somewhat reflexed (male); III–VI rounded, barely produced, rather flat, VII rounded, slightly thickened, faintly produced, rather flat (female). Male genitalia. Right paramere (Fig. 31, outer lateral view) with broad subrectangular head and short shaft; anterior margin of head bulbous. Ventral surface. Head. Rostrum nearly reaching posterior margin of carinate, subovate rostral groove. Thorax. Pro-, meso-, and metasternum fused, flat or slightly convex (not depressed) medially; suture line between metasternum and vmtg I of abdomen distinct. Abdomen. Ventral mediotergites (vmtg) I–III fused; other mediotergites well demarcated from each other; IV–VI flat (not depressed) medially; VII about 2.3× longer than VI medially, without wrinkles posteriorly (male), medially split into two subquadrate plates with inner margin of each plate about 1.5× longer than VI medially, surface rugose in inner posterior angle (female). Apodemal spots (sterna IV–VI) flat or slightly elevated, paler than or nearly concolorous with remainder of sterna (sometimes evanescent); inner and outer rows made of similarly sized spots. Connexivum faintly demarcated from remainder of venter (often more distinctly demarcated in female).
Material examined. 150 specimens (CMNZ, LUNZ, NZAC).
Geographic distribution (Fig. 79). Offshore Islands: TH–Great Island (NZAC) (Baylis Stream (LUNZ); Castaway Camp (LUNZ, NZAC); South East Bay (LUNZ); Tasman Stream, NW side (LUNZ); Tasman Valley (NZAC)). North East Island (LUNZ, NZAC). South West Island (NZAC). Three Kings Island [= Great Island], Summit (NZAC). West Island, south east end (NZAC).
Biology. Altitudinal range. Lowland to lower montane (up to 300 m). Habitat. Occurs in broadleaf forests and shrublands. Collected mostly in leaf litter; also in decaying wood debris. Seasonality. Adults and tenerals: November–December. Nymphs: November, December (mostly). Mating probably occurs in December.
Remarks. Lissaptera completa is endemic to the Three Kings Islands (TH). Larivière and Larochelle (2004) ’s North Island records from Northland (ND) were based on misidentified specimens.
