Table 2. Measurements (in µm) of Stegelleta laterocornuta sp. nov. and S. tuarua Yeates, 1967 from Castlecliff, New Zealand, the latter compared to the type population (presented as mean ± s.d. and (range) or only range).* Number of annuli from anterior end to nerve ring, excretory pore and deirid, respectively; - indicates that data is not available or not applicable.
