Tricheops remus View in CoL new species
( Fig. 2 View FIGURE 2 )
Etymology. This species name is derived from the Latin noun remus , an oar, referring to the paddle shape markings on the elytra of this species.
Diagnosis. Tricheops remus can be distinguished from other members of this genus by its larger body (length 20–22 mm), tan brown body colour with paddle blade shaped darker brown marking on elytra, the elytra 5.5 times length of head ( Fig. 2 View FIGURE 2 A) and the metafemur 5–6 times longer than its greatest width ( Fig. 2 View FIGURE 2 A,E).
Description. Length. 20–22 mm and length 5.0 to 5.5 times longer than width ( Fig. 2 View FIGURE 2 A). Dorsal and ventral surfaces bearing recumbent setae ( Fig. 2 View FIGURE 2 A–B). Head. Slightly constricted behind eyes and frontoclypeal suture moderately impressed ( Fig. 2 View FIGURE 2 C). Gland dispenser bearing group of stout setae ( Fig. 2 View FIGURE 2 C–D). Frontal interocular index 2.0 and upper lobes separated dorsally by 2.0–2.4 times diameter of antennal socket ( Fig. 2 View FIGURE 2 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. 2 View FIGURE 2 D). Antennal insertions separated by 2.2–2.4 times diameter of antennal foramen. ( Fig. 2 View FIGURE 2 C). Antennae. In female extending past middle of elytra, but not beyond apex of elytra (male unknown) ( Fig. 2 View FIGURE 2 A–B). Scape 0.5–0.7 of pronotum length and antennomere 3 about 1.0–1.1 times length of antennomere 4 ( Fig. 2 View FIGURE 2 B). Prothorax. Pronotal disc with two anterior moderately raised, sharp nodules and two posterior weakly raised rounded nodules ( Fig. 2 View FIGURE 2 A, D). Disc bearing medium recumbent setae only ( Fig. 2 View FIGURE 2 A, D). Pterothorax. Scutellum setose and mesocoxae separated at narrowest point by 0.4 of the cavity diameter ( Fig. 2 View FIGURE 2 A–B). Elytra. Length 5.5 times length of head and 4.0–4.1 times length of pronotum. Vestiture of elytra comprising of medium recumbent setae ( Fig. 2 View FIGURE 2 A). Legs. Metafemur length 5–6 times greatest width ( Fig. 2 View FIGURE 2 B, E). Abdomen. Ventrites with short recumbent setae. Ventrite 1 1.2–1.3 times length of ventrite 2, ventrite 5 in female 1.5 times longer than ventrite 4 and tapered toward a truncate apex ( Fig. 2 View FIGURE 2 B).
Types. Holotype female: Western Australia: 3km S of Kalbarri (27°43’S, 114°12’E), 7.xi.1971 u. v. light, N. McFarland (ANIC). Paratype female: same data as the holotype (ANIC).
Biological data. Both specimens were collected at night by ultraviolet light during the month of November.
Distribution. This species is known from two specimens collected 3 km south of Kalbarri in Western Australia.
