Asiolasma billsheari is a species of harvestmen belonging to the family Nemastomatidae.

[1] Asiolasma billsheari is a relatively small species with rather flat body and short hood.

Notably, only the prolonged anterior region of the prosoma and hood slightly are elevated, as in the geographically close species A. juergengruberi.

The pedipalpal patella has a bent and pointed apophysis medio-distally.

Additionally, I-IV areas of opisthosoma each has a para-median pair of low tubercles.
