Taksoni kirjeldused
Lopes & Pereira, 2018
Diagnosis (original): Meandering paths consisting of densely packed longitudinal patches or grooves side by side with straight parallel fine furrows or scratches engraved into the substratum.
Diagnosis (redefined): Groupings of closely spaced, elongated narrow (width <1/3 of length) furrows, irregularly distributed or arranged in patches disposed side by side, forming fan-shaped transverse rows covering large areas of the substrate. The furrows are straight and parallel to each other, with spacing between them ≤ 1/5 of the length of an individual furrow.
Voigt, 1977
Diagnosis: Minute patches or shallow grooves with parallel or subparallel tiny striae arranged side by side in transverse rows or irregularly distributed.
