Diagnosis. One specimen from Cairns has been sequenced (ANIC 25-066530, R. albocincta ; Ashman et al. 2022a): R. collaris is closely related to R. garnetensis sp. nov. (see above), R. piperitia and R. amicula , and is also morphologically similar to R. delicatula ( Figs. 6–8 View FIGURE 6 View FIGURE 7 View FIGURE 8 ). The latter three species have a clypeus extended beyond the mandibular articulation, grey mottled metanepisternum and elytra with the lateral white stripe never extending beyond the basal third. Rhytiphora piperitia and R. amicula are also slightly less elongate (body 3.0–3.1 times as long as wide); R. piperitia and R. delicatula have deeply emarginate eyes (not fully divided); R. amicula and R. delicatula have plain grey antennae (with tubercules slightly further apart: 3.8–3.9 widths apart) and no transverse stripes on the pronotum. Rhytiphora piperitia has banded antennae and dorsal dark patches on the elytra. Rhytiphora amicula has grey elytra with fine ochre mottling, and smaller sex patches (covering only half of ventrite 2). Rhytiphora delicatula has no distinct grooves on the pronotum and pale grey elytra with dorsal dark patches.

Description. Body small to medium-sized, elongate: body length 10.0–19.0 mm, width 3.0–6.0 mm. Winged. Dark brown-black with ochre setae (striped pronotum, mottled elytra) and lateral white stripe on elytra ( Figs. 7A View FIGURE 7 , 8E View FIGURE 8 ).

Head with frontoclypeus rectangular. Eyes moderately faceted, ringed with ochre setae, lobes fully divided. Lower lobes separated by 3.7–4.7 times eye width, approximately same length as gena. Upper lobes separated by 2.2 times width of antennal socket, 1.2 times as long as antennal socket. Antennal tubercules fairly prominent, separated by 3.3 times width of antennal socket. Clypeus flat, short (in line with mandibular articulation), with membranous anteclypeus visible beneath; mandibles apically slightly pointed, maxillary and labial palps fusiform. Frontoclypeus ochre, occipital suture with ochre outline. Antennae extending slightly beyond elytral apices in male, with ventral fringe of long, dense setae on antennomeres 2–11. Scape smooth, gradually expanding apically, 2.5 times as long as wide, 4 times longer than pedicel, shorter than antennomere 3, posteriorly extending a little beyond anterior margin of pronotum. Antennomere 3 longer than 4. Antennomeres usually mottled with grey-white setae (sometimes forming distinct bands).

Prothorax subquadrate, 0.8 times as long as wide, base distinctly narrower than humeri. Lateral margins with distinct anterior ridge; pronotal disc finely punctate with transverse grooves, setae ochre and usually forming distinct transverse stripes. Prosternal process narrow, arcuate. Procoxae sometimes with small spiniform projection in males.

Elytra finely punctate, granulate in basal and central thirds, without distinct basal projections. Elytra dark, heavily mottled with yellow-ochre setae; thin, curved white line on lateral margin, usually extending beyond basal third (either as complete, unbroken line to apices or interrupted by ochre mottling). Elytral apices slightly truncate.

Legs mottled with ochre setae; male protibial tubercule absent. Mesoventrite arcuate without anterior projection. Metaventrite twice as long as mesoventrite, metanepisternum and adjacent metaventrite usually white, rest of metaventrite mottled ochre.

Ventrite 2 with broad yellow-brown sex patches in male, covering almost entire surface; fringe of ventrite 1 slightly thicker in male than other ventrite fringes. Ventrite 5 slightly longer than 4 in female, with slight apical divot and endocarina.

Male genitalia: parameres narrowly separated at base, touching at apices, thick, apically blunt and setose; penis tip with slight projection ( Fig. 9C View FIGURE 9 ).

Distribution and host plants. Mesic east coast from Queensland down to South Australia. Localities include: Cairns, Hughenden, Rockhampton, Brisbane, Taree, Sydney, Canberra, Wyperfeld, Gawler. This species has been collected from Acacia , Allocasuarina , Angophora and Casuarina trees, as well as Dodonaea , Rosa and Viminaria shrubs.

Remarks. Following our examination of the type specimens of Symphyletes compos and R. maculosella (synonyms of R. albocincta ; Breuning 1961a), we have decided to synonymise this species with R. intertincta , R. parafarinosa , R. vermiculosa and Symphyletes vestigialis under the oldest species name: R. collaris (see Discussion for more details). The holotype of Saperda collaris was unable to be found and has presumably been lost. Here we designate ANIC 25-066530 as the neotype of Saperda collaris (male specimen with mitochondrial sequence data published in Ashman et al. 2022a, as R. albocincta ; Fig 10D View FIGURE 10 ).
