Diagnosis. This species differs from N. victoriae   in its smaller size (length less than 1.4 mm), shorter, broader body (less than 1.4 times combined elytral width), yellow colouration, with or without black elytral markings, and free portion of each paramere broad at base and narrowing towards subacute apex. It also differs from the two Chilean species, N. chilensis Bullians & Leschen   and N. latipennis Bullians & Leschen   , and the New Zealand N. nunni Bullians & Leschen   in that the elytra are primarily yellow, with black markings, if present, not occupying the entire width. Males of N. ornatus   differ from those of N. victoriae   and the three exotic species in having a single unmodified mesotibial spur (as opposed to two with one modified).

Description. Length 1.20–1.40 (1.30 ± 0.05) mm; body 1.25–1.40 (1.33) times as long as combined elytral width; greatest depth 0.67–0.79 (0.72) times elytral width. Colour of dorsal surfaces highly variable; elytra always at least partly yellow, but sometimes with varying amounts of black (a small black spot on each side of suture near middle, a larger black macula crossing both elytra at same point, a large triangular black macula extending from anterior end to about middle, narrowing posteriorly); entirely yellow elytra may appear striped due to longitudinal puncture rows; pronotum varying from yellow to yellowish-brown, reddish-brown or dark brown, but often lighter at the sides; head usually yellow but varying to red or reddish-brown; undersides dark brown or black but with abdominal apex yellow; legs yellowish-brown to reddish-brown or dark brown; antennae and palps yellow. Head 0.88 times as long as wide; distance across eyes 1.30 times as great as distance between them; inner eye margin without notch. Labrum 0.70 times as long as wide, broadly more or less evenly rounded apically, but with a median prominence cleft at middle. Antenna about 1.44 times as long as head width; 3rd antennomere 0.90 times as long as 4th; 11th antennomere 1.33 times as long as 10th, 1.74 times as long as wide and broadly rounded at apex. Galea slightly wider than lacinia at midpoint, widest at basal third with sides irregularly converging to narrowly rounded apex. Apical maxillary palpomere 2.0 times as long as wide, widest at middle, apex broadly, obliquely truncate with small, rounded apicolateral projection. Apical labial palpomere subulate, 2.0 times as long as wide, widest near base, with broad and slightly asymmetrical tip. Pronotum 0.24–0.34 (0.30) times as long as wide; prosternal process expanded and truncate at apex. Scutellar shield 0.2 times as wide as pronotum, 0.75 times as long as wide at base with narrowly acute apex. Elytra together 1.05–1.22 (1.12) times as long as wide and 4.55–7.10 (5.43) times as long as pronotum; elytral punctation and vestiture as in Fig. 89 View FIGURES 89–103 . Hind wings absent. Metanepisternum 0.71 times as long as mesepimeron and 1.52 times as long as wide, roughly pentagonal, with anterior, inner and out edges more or less straight, and posterior portion irregularly triangular, with posteromesal edge longer than posterolateral one. Mesotibia in male with one acute spur and no modified spur. Metatibia with one acute spur 0.87 times as long as first metatarsomere. Parameres about 0.70 times as wide as wide at about middle as penis at same point, sides weakly curved to subacute apex bearing several setae and connected to one another by subapical membrane. Penis slightly, gradually narrowed to subapex, then more strongly narrowed to subacute apex with median cleft, extending well beyond parameral apices.
