Tricheops guillemeti View in CoL new species
( Fig. 3 View FIGURE 3 )
Etymology. This species name is derived from the French noun guillemet (angle quotes), referring to the guillemet shaped markings on the pronotum of the species.
Diagnosis. Tricheops guillemeti can be distinguished from other members of this genus by its golden colouring with dark brown markings, two markings on lateral sides of pronotum and single dark brown marking on the posterior part of the pronotum ( Fig. 3 View FIGURE 3 A). T. guillemeti can be further distinguished by a lateral pronotum length 0.73 times height and the metafemur length 3.5–4.0 times width ( Fig. 3 View FIGURE 3 B, D–E).
Description. Length. 14–15 mm and length 5.0 to 5.5 times width. Dorsal and ventral surface bearing short recumbent setae (Fig. A–B). Head. Not constricted behind eyes and frontoclypeal suture weakly impressed ( Fig. 3 View FIGURE 3 A, C). Gland dispenser bears a single, moderately long, seta ( Fig. 3 View FIGURE 3 C–D). Frontal interocular index of 2.4 and upper lobes separated dorsally by 2.0–2.1 times diameter of antennal socket ( Fig. 3 View FIGURE 3 A, C). Number of stemmata at narrowest point of lobes (near junction with next lobe): upper lobe 8–10; median lobe 7; and lower lobe 10–11 ( Fig. 3 View FIGURE 3 D). Antennal insertions separated by 2.5 times diameter of antennal foramen ( Fig. 3 View FIGURE 3 C). Antenna. Exceeding apex of elytra by 2–3 antennomeres ( Fig. 3 View FIGURE 3 A). Scape 0.5–0.6 of pronotum length and antennomere 3 about 1.0–1.1 times the size of antennomere 4 ( Fig. 3 View FIGURE 3 A). Prothorax. Pronotal disc with two anterior moderately raised nodules with apex, two posterior slightly raised rounded nodules and disc bearing short recumbent setae only ( Fig. 3 View FIGURE 3 A, D– E). Pterothorax. Scutellum disc sparsely setose and mesocoxae narrowly separated, at narrowest point separated by 0.2 of the cavity diameter ( Fig. 3 View FIGURE 3 A–B). Elytra. Length 3.3 times the length of the pronotum and vestiture of elytra comprising of short recumbent setae ( Fig. 3 View FIGURE 3 A). Legs. Metafemur length 3.5–4.0 times greatest width ( Fig. 3 View FIGURE 3 B, E). Abdomen. Ventrites with short recumbent setae. Ventrite 1 about 1.5–1.6 times the length of ventrite 2, ventrite 5 is as long as ventrite 4 and apically emarginate ( Fig. 3 View FIGURE 3 B).

Biological data. The single specimen was collected in unknown circumstances.
Distribution. This species is known from a single specimen collected 2 km west south west of Muggan (now Warburton) Roadhouse and 156 km southwest of Warburton.
