Nothocyphon brevihamatus , n. sp.

(Figs. 128–131)

Type material: holotype ♂: New England Nat. Park, NSW, rainforest below Wright's L'kout, 11.x.66 E.Britton ( ANIC).

Habitus. Elongate oval, BL 2.3mm, BL/BW ~1.7. Light brown, legs yellowish brown, flagellar segments 2–8 infuscate. The dorsal punctation is fine, with blond semi-erect pilosity. The antennae are slender, the distal flagellar segments are cylindrical, about twice as long as wide, tip of last segment blunt.

Male. Segments 8 and 9 as described for the genus (Figs. 128, 129). Tegmen and parameres together form a thin rectangular frame (Fig. 130). The straight parameres are long. The thin sclerites of the tegmen widen abruptly and form a triangular lobe caudally from which the long straight parameres narrow continuously. They end as gently inwardly curved rods. Penis (Fig. 131) with oval pala supporting long thin inwardly curved parameroids with asperous tip. On their medial side they are excised in the area occupied by the short trigonium. Its basal arms are connected by a transverse bridge from which originate two parallel rods with rectangularly downcurved sharp tip.

Female. Unknown.

Note. The unusual shape of the genitalia, especially the profoundly divided trigonium reminded me of Petrocyphon species. However, the animal's body structure agrees with genus Nothocyphon . No similar species is known.

Etymology. Latin brevihamatus translates as short hooked; the name is an adjective.
