|Harvestman on a toilet roll; body length approx 8mm|
- The central stripe or 'saddle' is clearly outlines in black and paler in the middle, and its rear margin is cut off in a straight line.
- The legs are relatively short and robust (for a harvestman) unlike the longer and more spindly legs of genera such as Leiobunum. The femora are more or less cylindrical, while the tibiae and patellae are more angular in cross-section.
- The ocularium (eye-bearing structure, indicated by a blue arrow) is relatively small, has small bumps or 'tubercles' on top and is about twice its own length from the from edge of the cephalothorax.
- The trident (red arrow) is titled slightly upwards with the prongs diverging slightly and not especially different in length (the central one is a little longer, but starts further forward so the actual lengths are very similar).
- There is a paler line widening forward from the ocularium to the trident (outlined by green dashes).
- The sides of the cephalothorax bear small, variable prongs and protuberances (green circles).
