Redescription
Male ( Fig.39 View FIGURES 39 – 40 ). Body length: 11.8–20.3 mm.
Colour patterns. Body dark brown to reddish brown.
Head. Width 3.6–4.8 as long as distance between upper lobes of eyes; postclypeus with a transverse shining carina in front of transverse groove between tentorial pits; distance between lower lobes of eyes 1.6–1.8 distance between antennal socket and lateral angle of postclypeus, and 1.8–2.1 distance between upper lobes of eyes. Antennae distinctly longer than body; segment 3 as long as or shorter than scape and distinctly shorter than segment 4, segment 5 slightly longer than segment 6.
Thorax. Prothorax cylindrical, 1.0–1.1 as long as wide, widest in middle, sides rounded, with dense punctures and pubescence; disc with dense, pale yellow hairs, a linear longitudinal elevation and some short and less distinct transverse rugae. Prosternum in front of coxae divided by a shallow transverse depression into two parts, anterior carinate, with dense hairs, and posterior with dense deep punctures and pubescence. Elytra 2.6–3.1 as long as shoulders, and 3.7–4.0 as long as prothorax. Metasternum with dense pubescence and sparse erect hairs. Femora with dense pubescence; hind femora 1.8–2.2 as long as prothoracic width.
Terminalia. Apex of both ventral and dorsal median lobes pointed, and ventral lobe longer than dorsal lobe. Basal unspined region of internal sac with a shaped chitinous structure near spined region; spined region about as long as unspined region, and divided into 3 sections: first section with sparse, simple spines; second section> 2 as long as first section, with dense multibranched spines in middle and dense, transversely arranged, sawshaped spines at both sides; third section slightly longer than sections 1+2, with dense, long, simple spines and a Yshape chitinous structure ( Fig. 41 View FIGURES 41 – 48 ). Eighth sternite rounded at sides, apex slightly emarginated, with setae at apex and sparse, simple microspines on sides of ventral surface; middle region with a semicircular membranous area at middle area; width 3.0–3.1 as long as length (middle), and 3.0–3.7 as long as length of needle ( Fig. 42 View FIGURES 41 – 48 ). Eighth tergite rounded at apex, dorsal surface with dense microspines, and waveshaped spines ( Fig. 43 View FIGURES 41 – 48 ). Parameres 1/7–1/9 length of tegmen ( Fig. 44 View FIGURES 41 – 48 ). Ventral apodeme with an inner process between arms, stem about as long as arms ( Fig. 45 View FIGURES 41 – 48 ).
Female ( Fig. 40 View FIGURES 39 – 40 ). Body length: 14.3–20.3 mm.
Antennae as long as or slightly longer than body. Sides of prothorax without punctures; prothorax widest behind middle. Elytra 2.7–2.9 as long as shoulders and 3.7–3.8 as long as prothorax.
Ovipositor. Paraproct bacculi short, 0.6 length of proctiger baculi, a large area around dorsal baculi sclerotised. Length of stylus distinctly shorter than width of coxite ( Fig. 46 View FIGURES 41 – 48 ).
Spermatheca. Robust, terminal part slightly curved. Spermathecal gland arising near base of spermatheca ( Fig. 47 View FIGURES 41 – 48 ).
Eighth sternite. Rectangular, width 2.0–2.4 as long as length; length of needle 2.1– 2.8 as long as length of eighth sternite ( Fig. 48 View FIGURES 41 – 48 ).
Biology
Known host plants are Acacia myrtifolia and Weinmannia sylvicola . Adults were collected between October and February. Females could be collected one month earlier than males. About 60% of adults were collected in December and January.
Distribution ( Fig. 49 View FIGURE 49 )
Distributed in northern South Island, including Marlborough Sounds, Nelson, and Marlborough and the North Island, including Wellington, Northland and Coromandel.
Comments
This species is similar to O. hirta but differs by having the distance between the lower lobes of the eyes 1.8–2.1 distance between the upper lobes of the eyes; transverse rugae on pronotal disc shorter and less distinct; internal sac with a Yshape chitinous structure. The species also resembles O. simplicicollis but differs by having antennal segment 4 distinctly longer than segment 3; apex of both ventral and dorsal median lobes sharply pointed; internal sac with a shaped chitinous structure in unspined region and with dense long simple spines around Yshaped chitinous structure in spined region.
