Nothocyphon naso , n. sp.

(Figs. 156–159)

Type material: 1 ♂, holotype, Mossman Bluff Track 5–10km NW Mossman, N.Qld., 17–31 Dec 1988, Monteith, Thompson & ANZSES, Site 9, 1260m, flt. intercept (QM Reg.No. T227420); 1 ♂, paratype: Mossman Bluff 10km NW Mossman, N.Qld., 17–18 Dec 1988, 1100–1300m, Monteith & Thompson (QM Reg.No. T227419) ( QMSB).

Habitus. BL 2.4mm, BL/BW ~1.6, elongate-oval, fairly convex. The pattern resembles N. lindensis , the dorsal side is yellow with a brown parasutural spot. Antennae short, flagellar segments slightly conical, not even twice as long as wide at apex. The punctation of the forebody is very fine, on the pronotum essentially only the spaced setal insertions are visible. Punctures on elytra normal, fine, separated by twice their own diameter, the yellow pilosity rather apparent.

Male. Segments 8 and 9 as for the genus (Figs. 156, 157). The penis is slender, the front end of the pala is rounded (Fig. 158). The trigonium inserts just beyond midlength. It is carrot-shaped with wide base narrowing in almost straight line, apex pointed. Raised cones stand in an irregular row along the side, the basal cones are largest, tooth-like and reach over the edge, growing finer towards the tip. The parameroids are closely appressed to the trigonium, straight, with obtuse tip and large outwardly directed triangular process near midlength. Immediately basally from trigonium and parameroids occur two crescent-shaped pale sclerites that are laterally connected to a slender forward-pointing strut. The parameres are connected by a strong arched bar-like tegmen (Fig. 159). Each paramere is a strong rod which widens abruptly a short distance from the base and is divided into 2−3 very large rigid spines and an elongate swelling beset with numerous teeth along its medial face. The largest teeth occur near the base of the swelling.

Female. Unknown.

Note. Resembles N. lindensis , N. ypsilon as well as N. armatus in habitus, but not in the genitalia.

Etymology. The name (the Latin noun naso , the nose) alludes to the nose-like triangular process on the parameroid.
