Habitus. Elongate oval, elytral margins almost parallel. BL 2.2−3.2 mm, BL/BW ~1.7. Brown to almost black, in relatively pale specimens the sutural interval is vaguely reddish. The appendages are yellowish to brown. The antennal base is unmodified, distal flagellar segments are just twice as long as distally wide. Head and scutellum with fine granular punctures, the granular punctures on the pronotum are larger. Elytra with still larger normal punctures. The pilosity is short, semi-erect, yellowish.

Male (Figs. 32−37). Segments 8 and 9 as for the genus. Penis slender, pala very narrow, longitudinally folded, forming a slender anterior tip. Trigonium and parameroids originate near the caudal third of penis. Trigonium flat, sides and apex with small teeth. Shape varies from triangular to broadly tongue-shaped and truncate; see Notes section below. The parameroids are gently curved flat rods that narrow caudally and are longer than the trigonium. The inner edge is straight, the outer one convex. The tegmen is a long thin sclerite loop caudally supporting the band-like parameres whose caudal portion widens, surrounding the penis ventrolaterally. Parameres with variable armature (see notes), the caudal teeth are always largest. A blunt spur-like sclerite supports the ventrolateral end of the paramere (e.g., Figs. 32, 33, 37).

Female (presumed). S7 with two paramedian oval patches of finely porous cuticle from where minute converging canals lead inward. Near the medial edge of each modified cuticular area stands a group of erect hairs that differ from the normal fine tomentum (Fig. 38). T8 and ovipositor unmodified, rods of S8 connected by a wide ring in front (Fig. 39).

Prehensor (Fig. 40) located in an abruptly widening section of the oviduct. Two parallel bands of slender spines lead towards the wide section. Its projecting caudo-lateral angles are two apparently extensible pockets with concentric folds. Between them lies a trapezoidal sclerite with two paramedian ridges armed with strong anteriorly directed teeth. Anteriorly, on the opposite side of the duct a toothed sclerite ring is located. It ends in two slender strips extending forward towards the balloon-shaped bursella, surface with minute sun-like cuticular ornaments.

Notes. The male genitalia vary. In most specimens the trigonium is bluntly rounded but the tip may also be narrow and pointed, or spade-shaped (Figs. 33, 36, 37). The armature of the parameres varies also. A continuous band of coarse teeth may extend from the large caudal hooks to the anterior end of the paramere (Fig. 33). In other specimens the armature may be altogether finer (Fig. 37). In still others, a few fine teeth only may be present between the large distal hooks and the basal patch of teeth (Fig. 36). In groups of specimens taken together the various morphs coexist, variation seems to be individual. However, ten males taken together at the Gordon River are all small (2.2−2.6mm; Fig. 37), have relatively short genitalia, a sharply pointed trigonium, more strongly bulging parameroids and weak armature of the parameres. The female in that sample has a spermatophore in the bursella. Another male taken at the Lower Gordon R. is normal and resembles Fig. 33. The presumed females agree in habitus and were taken together with male N. lanceolatus.

J. Armstrong attached type labels to specimens of N. lanceolatus but assigned them to two different taxa none of which he described. At the same time he confused N. lanceolatus with other taxa, e.g., N. frater and another presently undescribed species.

N. lanceolatus is widespread in Tasmania. Its occurrence in the Grampians should be confirmed by contemporary collections.

Etymology. The name is a Latin adjective describing the lanceolate shape of the pala.
