Diagnosis. This species differs from N. ornatus in its larger size (length greater than 1.4 mm), more elongate body (more than 1.4 times combined elytral width), darker elytra (mostly dark brown or black), mesotibia in both sexes with two spurs, one of which in male is apically widened and cleft, and free portion of a paramere narrow and parallel-sided. The yellowish-brown head and pronotum and the dark brown or black elytra with a reddish sutural stripe separates this species from all other described Noteucinetus , and the single metatibial spur also separates it from N. nunni Bullians & Leschen.

Description. Length 1.45–1.65 (1.55 ± 0.06) mm; body 1.42–1.57 (1.47) times as long as combined elytral width; greatest depth 0.73–0.78 (0.75) times elytral width. Colour of head and pronotum yellow to yellowishbrown; elytra primarily dark brown to black, sometimes with red along suture; undersurfaces reddish-brown anteriorly and dark brown posteriorly; legs yellowish-brown; antennae and palps yellow. Head 0.90 times as long as wide; distance across eyes 1.32 times distance between them; inner eye margin without notch. Labrum 0.65 times as long as wide, broadly more or less evenly rounded apically, but with a median prominence cleft at middle. Antenna about 1.4 times as long as head width behind eyes; 3rd antennomere 0.81 times as long as 4th; 11th antennomere 1.32 times as long as 10th, 1.80 times as long as wide and narrowly rounded at apex. Mandibular mola well developed. Galea subequal in width to lacinia at midpoint, widest at middle with sides irregularly converging to narrowly rounded apex. Apical maxillary palpomere 1.57 times as long as wide, with broadly, obliquely truncate apex. Apical labial palpomere 1.87 times as long as wide, more or less fusiform with moderately broadly rounded apex. Pronotum 0.29–0.37 (0.34) times as long as wide; prosternal process expanded and truncate at apex. Scutellar shield 0.3 times as wide as pronotum and 0.55 times as long as wide at base, with narrowly acute apex. Elytra 1.19–1.30 (1.24) times as long as wide and 4.71–6.50 (5.35) times as long as pronotum. Elytral punctation and vestiture as in Fig. 90 View FIGURES 89–103 . Metanepisternum 0.73 times as long as mesepimeron, 1.91 times as long as wide, asymmetrically quadrate with all edges straight, the anterior one slightly oblique and the posterior one strongly oblique. Hind wing reduced and flap-like. Mesotibia in female with two acute spurs, one about 0.45 times as long as first mesotarsomere and the other slightly shorter; male with acute spur about as long as in female and a modified spur arising at an angle, slightly shorter, thicker and widened at apex, with a small articulated piece arising from within a cleft. Metatibia with one acute spur 0.75 times as long as first metatarsome. Parameres with apical free sections very narrow with narrowly rounded apex bearing several setae; connecting membrane located well away from apices. Penis slightly, gradually narrowed to subapex, then more strongly narrowed to subacute apex with median cleft, extending well beyond parameral apices.

Distribution. Known only from eastern VIC but probably occurs in montane regions of NSW or the ACT. Biology. This species was most often collected by pyrethrum fogging, but a number of specimens were collected by hand under bark of logs, in berlesates of sifted log and leaf litter, and in flight intercept/trough traps. Etymology. Derived from the state of Victoria.
