Carventaptera hallae Larivière and Larochelle. Holotype: female (NZAC) labeled “ NEW ZEALAND RI Ruahine Ra. [= Range] Colenso Trig Tk [= Track] 600m 3946 S 17602 E [= 39 ⁰46’S 176 ⁰02’E] 10.XII.2010 Larivière , Larochelle (typed) / Mixed forest (beech-broadleaf-podocarp). Underside of 5 cm diam. rotten fallen branch #4; [at] base of Blechnumferns. (typed) / HOLOTYPE [female symbol] Carventaptera hallae Larivière & Larochelle, 2022 (red label; typed).” Paratypes: 2 males (LUNZ, NZAC) and 2 females (NZAC) from the same locality as the holotype, 1 female (NZAC) from Ruahine Range, Limestone Road end Track, 1 female (NZAC) from Ruahine Range, Rangiwahia Hut Track, and 1 female (LUNZ) from Ruahine Range, start of Daphne Hut Track, bearing blue paratype labels.

Description (incrustation removed). Body length about 4.1 mm (male), 4.9 mm (female). Dorsal color (male) dark reddish brown except for paler backward projection of mesonotum and adjacent metanotum-dmtg I area (other thoracic and abdominal callosities and markings obscure); darker brown to black on collar and to varying degrees thorax and abdomen. Female similarly colored. Eyes reddish. Antennae and legs concolorous with or slightly paler than main body (apices of femora and entire tibiae, often paler). Ventral color mostly matching main dorsal color; thoracic sterna sometimes slightly paler, vmtg III–VI with dark median foveae. Head. Antenniferous tubercles narrowly subconical, their apices divergent and slightly reflexed. Postocular tubercles rounded-subtriangular, slightly produced laterally, flat to slightly reflexed. Lateral margins of head flat to slightly reflexed. Thorax. Pronotum about 3.0× wider than long medially, including collar (male), 3.2× (female); about as wide as or barely wider than mesonotum. Anterolateral angles narrowly rounded-subtriangular (not appearing swollen),slightly to moderately produced in front of collar,slightly to moderately reflexed. Lateral margins slightly to moderately sinuate, moderately oblique, slightly to moderately reflexed. Posterolateral angles bluntly roundedsubtriangular, moderately to strongly produced into a short upper tubercle and a longer lower tubercle, slightly reflexed. Mesonotum about 3.2× wider than long medially, including backward projection. Lateral portions with one or two small, rounded callosities, coarse granules mostly coalesced into oblique wrinkles and, submarginally, closely set finer granules forming a thickened border. Metanotum. Lateral portions with an obscure, moderately large, narrow semicircular or vermiculate plate, coarse granules coalesced into oblique wrinkles, and submarginally, a small, rounded callosity, coarse granules and closely set finer granules forming a thickened border anteriorly. Abdomen. Tergal plate (dmtg III–VI). Lateral margins subrectilinear to slightly convex. Inner rows of apodemal markings made of obscure, suboval, smooth spots; outer rows made of obscure, more rounded, smaller spots. Dmtg VII with a longitudinal slit on a moderate elevation medially (male); with a transverse sulcus followed by a wide bead posteromedially (female). Connexivum slightly to moderately reflexed (more reflexed in male). Dorsal laterotergites (dltg) with a pair of obscure apodemal spots. Posterolateral angles of dltg III–VI rounded-subquadrate, unproduced (V–VI thickened), VII narrowly rounded-subtriangular, barely produced, moderately reflexed (male); III–VI rounded-subquadrate, unproduced (V–VI thickened), VII broadly roundedsubquadrate, unproduced, barely reflexed (female). Male genitalia. Right paramere ( Fig. 37 , inner lateral view) broad and flat; head broadly rounded-subtriangular, posterior margin thickened from apex to about midlength of paramere, ending in a narrowly sinuate-subtriangular flange (appearing as a narrow, subtriangular projection in dorsolateral view, Fig. 27 ). Ventral surface. Abdomen. Apodemal spots (vmtg III–VI) flat or slightly elevated, nearly concolorous with remainder of venter; inner rows usually made of larger, more obscure spots.

Other characters as in C. spinifera .

Material examined. 235 specimens ( AMNZ, LUNZ, NZAC).

Geographic distribution ( Fig. 75 ). North Island: AK, BP,CL, GB, ND, RI, TK, WO.

Biology. Altitudinal range. Lowland to montane (up to 800 m). Habitat. Found in broadleaf–podocarp forests, southern beech ( Nothofagus sensu lato) forests or mixed forests. Collected in large numbers under the loose bark, in wood interstices or on the moist, often moldy, undersurface of fallen rotting branches (5–10 cm diameter) and logs; more rarely collected in leaf or leaf and twig litter. Seasonality. Adults: throughout most of the year (mostly December–January). Tenerals and nymphs: December. Mating observed in December (fully mature adults and tenerals).

Remarks. This species is named after Grace Hall (Landcare Research, Auckland), a longtime friend and colleague, for her special help and encouragement in our Hemiptera research over the last three decades, and for her unwavering commitment to the New Zealand Arthropod Collection, its staff, and the New Zealand entomological community. In addition to characters of the male parameres, Carventaptera hallae is distinguished from C. spinifera by the following features: narrower shape; darker color, with obscure plates, callosities and other markings; lateral margins of head flat to slightly reflexed; antenniferous tubercles narrowly subconical, not strongly reflexed;postocular tubercles rounded-subtriangular, slightly produced laterally, not strongly reflexed; pronotum with anterolateral angles more narrowly rounded-subtriangular, less strongly produced in front of collar, lateral margins less sinuate, and posterolateral angles produced into two tubercles of unequal length. Carventaptera hallae is broadly distributed on the North Island, north of the Wairarapa (WA) and Wellington (WN) regions. The Northland (ND) record is based on a single teneral female from Whangarei (NZAC).
