Nothocyphon
sp. A: 52, lobes of S9, tegmen with parameres and remains of pala (p) and of a parameroid (pd).—
N. denticulatus
: 53, T8; 54, T9; 55, S8 and S9, superimposed; 56, penis and tegmen. The scale applies to Fig. 56; for the other figures, its length corresponds to 400µm.
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.
