Nothocyphon sp. A

( Fig. 52 )

Material examined: 1♂: 35.51S 146.15E VIC Baw Baw Alpine Res. 1.2 km NE Neulynes Mill, 1145m, 28.Jan.– 10.Feb. 1987 A.Newton & M.Thayer \ wet scler.for. FMHD 87 236 Flight interception trap ( ANIC).

Note. The 2.6 mm long brown beetle is severely damaged and not formally named but is mentioned to document the diversity of the group.

Segment 8 missing. Of segment 9 remain one apodeme of the tergite (not shown) and the unusual, strongly sclerotized angular distal lobes of S9. Of the penis only the slender pala is undamaged. The parameroids seem to resemble the related species, shape of trigonium unknown. The tegmen is strong and supports parameres composed of three large components. The median one has a large medially projecting knee-like sclerite with a few teeth. Caudally it is tongue-shaped, with a few basolateral teeth and a large subapical one. The medial lobe bears a single series of spines along its edge, the basolateral lobe several, in irregular arrangement.
