Remarks

• Systematics: This genus is monotypic. S. fagi has been described in some detail by Lambdin and Kosztarab (1976) and, based on their description, the key character-states appear to be: (i) small closed pores, each subequal in size to quinquelocular disc-pores, present in a complete submarginal line, extending from head to posterior abdomen; (ii) quinquelocular disc-pores also present in a line submarginally between spiracles and extending posteriorly to about abdominal segment III; (iii) spinose setae along inner margin of each anal lobe absent; (iv) each anal lobe with two short spinose setae on dorsal surface; (v) 8-shaped pores absent from dorsum apart from a transverse line across about abdominal segment VIII; (vi) 8-shaped pores present in a marginal band, probably mainly on venter; (vii) 8-shaped pores on venter also in sparse transverse lines on abdominal segments; (viii) posterior stigmatic band not bifurcated; (ix) cribriform plates present, with two submedial plates on each side of abdominal segment IV; (x) loculate disc-pores absent nenear each antenna, and (xi) tubular ducts all subequal in size. S. fagi is only known from South Island, New Zealand. It seems more likely that it is closest to Antecerococcus. (Hodgson & Williams, 2016)
• Structure: Female test is globose. The exuviae in the middorsal region is flat and shiny, brown, with long white bands of wax in spiracular furrows. Male test is elliptical, yellowish. It has no distinct median carina present and the anal flap is slightly depressed. Adult female is elliptical with membranous derm (Lambdin & Kosztarab, 1976).
