Normally quite a dark harvestman with a waisted saddle which becomes parallel sided after the constriction. The small trident is conspicuous under a hand-lens because the pale members can be accompanied by many additional tubercles. The ocularium is dark but can have some quite striking light patches on it - especially around the conspicuous tubercles. Legs usually conspicuously annulated - pale and dark brown.

Oligolophus tridens - trident and associated tubercles are different.  

Paroligolophus agrestis but this species only has some small bristles rather than a trident.

Photos clearly showing the trident and ocularium are required.
